PCCN® Exam (Progressive Care Certified Nurse) — Questions and Answers

Question 1: Which of the following rhythms requires immediate defibrillation?

Ventricular fibrillation (Correct answer)
Atrial flutter
Second-degree AV block type II
Sinus tachycardia

Correct answer: Ventricular fibrillation

Ventricular fibrillation (VFib) is a chaotic, life-threatening arrhythmia characterized by disorganized electrical activity in the ventricles, leading to ineffective cardiac contraction and immediate loss of consciousness. Immediate defibrillation is crucial to terminate VFib and restore a perfusing rhythm, as it is a pulseless rhythm requiring immediate electrical intervention.

Question 2: Which finding indicates a patient with sickle cell crisis is developing acute chest syndrome?

New infiltrate on chest X-ray with hypoxia (Correct answer)
Pain localized to the lower back
WBC of 12,000/mm³
Hemoglobin of 10 g/dL

Correct answer: New infiltrate on chest X-ray with hypoxia

Acute chest syndrome is diagnosed by a new pulmonary infiltrate on imaging combined with respiratory symptoms such as hypoxia.

Question 3: The nurse is differentiating between delirium, dementia, and depression ('the 3 Ds') in a progressive care patient. Which feature is MOST characteristic of delirium compared to the other two?

Acute onset with fluctuating level of consciousness (Correct answer)
Gradual onset over months to years
Persistent low mood with anhedonia
Intact short-term memory with personality changes

Correct answer: Acute onset with fluctuating level of consciousness

Delirium is distinguished by its acute onset (hours to days), fluctuating course, and impaired consciousness, distinguishing it from the gradual progression of dementia and the mood-focused presentation of depression.

Question 4: Which of the following medication classes is considered first-line for rate control in a stable patient newly diagnosed with atrial fibrillation and a rapid ventricular response?

Beta-blockers (Correct answer)
Digoxin
Sodium channel blockers
Amiodarone

Correct answer: Beta-blockers

For stable patients with atrial fibrillation and a rapid ventricular response, beta-blockers (e.g., metoprolol) or non-dihydropyridine calcium channel blockers (e.g., diltiazem) are recommended as first-line agents for rate control. Amiodarone is typically used for rhythm control or in specific situations like heart failure. Digoxin is generally considered a second-line agent as it is less effective at controlling heart rate during exercise. Sodium channel blockers are used for rhythm control, not rate control.

Question 5: Which of the following medications is classified as a beta-1 selective blocker and commonly used in heart failure management?

Propranolol
Carvedilol
Labetalol
Metoprolol (Correct answer)

Correct answer: Metoprolol

Metoprolol is a beta-1 selective blocker, meaning it primarily blocks beta-1 adrenergic receptors in the heart, reducing heart rate and myocardial contractility. This action helps to decrease myocardial oxygen demand and is beneficial in managing heart failure. Propranolol, carvedilol, and labetalol are non-selective or have additional alpha-blocking properties.

Question 6: Which finding is most consistent with a left hemispheric stroke?

Impulsive behavior and neglect
Right-sided hemiparesis and aphasia (Correct answer)
Left-sided weakness and visual neglect
Intact speech with right-sided weakness

Correct answer: Right-sided hemiparesis and aphasia

The left cerebral hemisphere controls the right side of the body and is typically dominant for language in most individuals. Therefore, a left hemispheric stroke commonly results in right-sided weakness or paralysis (hemiparesis/hemiplegia) and language disturbances such as aphasia (difficulty with speech or understanding). This pattern of deficits helps localize the stroke to the left hemisphere.

Question 7: A patient presents with slurred speech, facial droop, and right-sided weakness. Which diagnostic test should be prioritized first?

Computed Tomography (CT) scan of the head (Correct answer)
Magnetic Resonance Imaging (MRI)
Carotid Doppler ultrasound
Electroencephalogram (EEG)

Correct answer: Computed Tomography (CT) scan of the head

A patient presenting with acute neurological deficits like slurred speech, facial droop, and weakness suggests a possible stroke. A CT scan of the head is prioritized to rapidly differentiate between ischemic and hemorrhagic stroke, as this distinction dictates immediate treatment. This quick assessment is critical for timely intervention, such as administering thrombolytics for ischemic stroke, and improving patient outcomes.

Question 8: A patient in neurogenic shock following a cervical spine injury presents with hypotension and bradycardia. This pattern is caused by:

Parasympathetic overstimulation due to pain
Increased intracranial pressure
Massive hemorrhage from cord injury
Loss of sympathetic nervous system tone below injury level (Correct answer)

Correct answer: Loss of sympathetic nervous system tone below injury level

Cervical cord injury disrupts sympathetic outflow, causing loss of vasomotor tone and cardiac acceleration, resulting in hypotension and bradycardia.

Question 9: Confidentiality is best maintained in the progressive care setting by:

Speaking quietly during handoff at the nurses' station (Correct answer)
Sharing information only with friends or family
Using only initials on whiteboards
Discussing patient cases during breaks in the lounge

Correct answer: Speaking quietly during handoff at the nurses' station

Maintaining patient confidentiality is paramount in healthcare. Speaking quietly during handoff reports at the nurses' station minimizes the risk of unauthorized individuals overhearing sensitive patient information. Discussing cases in public areas, using only initials, or sharing information with friends/family are breaches of confidentiality and HIPAA violations.

Question 10: Which laboratory result is most indicative of acute pancreatitis?

Elevated amylase and lipase (Correct answer)
Elevated alkaline phosphatase
Decreased ALT and AST
Low bilirubin

Correct answer: Elevated amylase and lipase

Acute pancreatitis involves inflammation of the pancreas, leading to the release of digestive enzymes into the bloodstream. Amylase and lipase are pancreatic enzymes, and their levels become significantly elevated in acute pancreatitis, often several times the normal range. Lipase is generally considered more specific for pancreatitis than amylase.

Question 11: Post-intensive care syndrome (PICS) includes which combination of long-term sequelae that progressive care nurses should educate patients and families about?

Cognitive impairment, psychological disturbances (PTSD/depression/anxiety), and physical weakness (Correct answer)
Chronic pain, insomnia, and weight gain only
Hypertension, diabetes, and renal failure
Cardiac arrhythmias, neuropathy, and visual changes

Correct answer: Cognitive impairment, psychological disturbances (PTSD/depression/anxiety), and physical weakness

PICS encompasses a constellation of new or worsening impairments in cognitive function, mental health (PTSD, depression, anxiety), and physical/functional status that persist after critical illness.

Question 12: A patient with a spinal cord injury at the level of T4 is at risk for which potentially life-threatening complication?

Autonomic dysreflexia (Correct answer)
Cerebral aneurysm
Seizures
Brain herniation

Correct answer: Autonomic dysreflexia

Autonomic dysreflexia is a potentially life-threatening condition that can occur in patients with spinal cord injuries at or above T6. It is characterized by an exaggerated sympathetic response to noxious stimuli below the level of injury, leading to severe hypertension, bradycardia, and headache. A T4 injury places the patient at high risk for this emergency, requiring immediate recognition and management.

Question 13: What is the most serious complication associated with esophageal varices?

Acid reflux
Strangulated hernia
Massive upper GI bleeding (Correct answer)
Aspiration pneumonia

Correct answer: Massive upper GI bleeding

Esophageal varices are dilated blood vessels in the esophagus that develop due to portal hypertension in liver disease. These vessels are fragile and prone to rupture, leading to life-threatening, massive upper gastrointestinal bleeding. This complication is a medical emergency with a high mortality rate, making it the most serious concern.

Question 14: A nurse is caring for a patient experiencing opioid withdrawal. Which cluster of symptoms should the nurse expect?

Bradycardia, hypotension, miosis, and sedation
Hypertension, fever, hallucinations, and seizures
Bradypnea, hypothermia, constipation, and euphoria
Tachycardia, diaphoresis, piloerection, and yawning (Correct answer)

Correct answer: Tachycardia, diaphoresis, piloerection, and yawning

Opioid withdrawal produces a hyperadrenergic state characterized by tachycardia, diaphoresis, piloerection (goosebumps), yawning, lacrimation, and muscle aches.

Question 15: A nurse assigned to care for a former romantic partner should:

Continue with care as assigned
Request reassignment to avoid potential conflict (Correct answer)
Inform the patient not to disclose their past relationship
Ask a co-worker to do all treatments

Correct answer: Request reassignment to avoid potential conflict

To maintain professional boundaries, avoid potential conflicts of interest, and ensure objective care, a nurse should request reassignment if a patient is a former romantic partner. This protects both the patient's privacy and the nurse's professional integrity, preventing any emotional or personal biases from affecting care. Continuing care could compromise the therapeutic relationship.

Question 16: A nurse notices that a colleague is documenting vital signs without actually taking them. What is the most appropriate first step?

Ignore the situation
Report the behavior to the nurse manager (Correct answer)
Confront the colleague in front of others
Document your own vital signs over theirs

Correct answer: Report the behavior to the nurse manager

Falsifying documentation is a serious breach of professional ethics and patient safety. The most appropriate first step is to report the behavior to the nurse manager, who has the authority and responsibility to address such misconduct. This ensures patient safety is maintained and professional standards are upheld, without directly confronting the colleague in a potentially unprofessional manner.

Question 17: A patient with MODS (multiple organ dysfunction syndrome) has the following: creatinine 3.1, bilirubin 4.2, PaO2/FiO2 ratio of 180, and GCS of 12. How many organ systems are affected?

Three
Two
Four (Correct answer)
Five

Correct answer: Four

Renal (creatinine), hepatic (bilirubin), pulmonary (PaO2/FiO2 < 300), and neurological (GCS) dysfunction indicate four organ systems are failing.

Question 18: A patient is prescribed filgrastim (G-CSF) following chemotherapy. The nurse understands this medication works by:

Suppressing the immune response
Replacing clotting factors
Stimulating platelet production
Stimulating neutrophil production (Correct answer)

Correct answer: Stimulating neutrophil production

Filgrastim (G-CSF) stimulates the bone marrow to produce neutrophils, reducing the duration and severity of neutropenia after chemotherapy.

Question 19: A patient with liver cirrhosis is at risk for hepatic encephalopathy. Which assessment finding most supports this diagnosis?

Clay-colored stools
Hypoactive bowel sounds
Asterixis (flapping hand tremor) (Correct answer)
Right upper quadrant pain

Correct answer: Asterixis (flapping hand tremor)

Hepatic encephalopathy is a neurological complication of liver cirrhosis caused by the accumulation of toxins, primarily ammonia, in the bloodstream. Asterixis, often called a 'liver flap,' is a characteristic motor disturbance seen in patients with this condition. It indicates impaired neurological function due to the liver's inability to detoxify harmful substances.

Question 20: A patient has a central venous catheter. Which sign most suggests a catheter-related bloodstream infection?

Phlebitis and vein discoloration
Edema around the insertion site
Fever with no obvious source (Correct answer)
Tachypnea and wheezing

Correct answer: Fever with no obvious source

Fever with no obvious source is a hallmark sign of a catheter-related bloodstream infection (CRBSI). While local signs like redness or edema can occur, a systemic fever without another identifiable cause strongly suggests that the central line is the source of infection. Prompt investigation and management are crucial to prevent severe sepsis.

Question 21: A patient with acute respiratory distress syndrome (ARDS) is receiving mechanical ventilation with a low tidal volume strategy. What is the primary rationale for this intervention?

To facilitate sedation and neuromuscular blockade.
To decrease the patient's work of breathing and improve comfort.
To prevent hypotension and cardiovascular collapse.
To reduce the risk of barotrauma and volutrauma. (Correct answer)

Correct answer: To reduce the risk of barotrauma and volutrauma.

The primary goal of a low tidal volume ventilation strategy (typically 4-8 mL/kg of predicted body weight) in ARDS is to minimize ventilator-induced lung injury (VILI). High tidal volumes can overdistend and injure the less-affected alveoli, leading to volutrauma and barotrauma. Keeping plateau pressures below 30 cm H2O is a key component of this protective strategy.

Question 22: Which ethical principle involves doing no harm to the patient?

Justice
Veracity
Nonmaleficence (Correct answer)
Autonomy

Correct answer: Nonmaleficence

Nonmaleficence is the ethical principle that means "do no harm." In nursing, this involves avoiding actions that could intentionally or unintentionally cause harm to a patient. It is a fundamental principle guiding all healthcare interventions and decisions, ensuring patient safety is prioritized.

Question 23: A patient receiving heparin begins to develop signs of heparin-induced thrombocytopenia (HIT). What is the most appropriate action?

Increase the heparin dose
Administer vitamin K
Discontinue heparin and notify the provider (Correct answer)
Administer platelet transfusion

Correct answer: Discontinue heparin and notify the provider

If a patient develops signs of heparin-induced thrombocytopenia (HIT), such as a significant drop in platelet count or new thrombosis, the most appropriate and immediate action is to discontinue all heparin products. Notifying the provider is crucial for initiating alternative anticoagulation and further management, as HIT is a serious, potentially life-threatening condition.

Question 24: Which finding best differentiates cardiogenic shock from hypovolemic shock?

Tachycardia
Hypotension
Elevated PCWP and reduced cardiac output (Correct answer)
Cool, clammy skin

Correct answer: Elevated PCWP and reduced cardiac output

Cardiogenic shock is characterized by elevated PCWP (fluid backing up) and reduced cardiac output, unlike hypovolemic shock which has low PCWP.

Question 25: A patient is prescribed a fentanyl patch for chronic pain. Which of the following instructions is most important?

Change the patch every 12 hours
Apply only to the upper chest
Apply over broken skin for better absorption
Avoid exposing the patch to heat (Correct answer)

Correct answer: Avoid exposing the patch to heat

Fentanyl patches release medication systemically, and heat (from heating pads, hot baths, or fever) can significantly increase the rate of fentanyl absorption. This accelerated absorption can lead to dangerously high serum fentanyl levels, increasing the risk of severe respiratory depression and overdose. Patients must be educated to avoid heat exposure to the patch.

Question 26: A nurse is preparing to suction a patient’s endotracheal tube. What is the most appropriate action before suctioning?

Turn off the ventilator
Instill normal saline into the airway
Increase suction pressure to maximum
Hyperoxygenate the patient (Correct answer)

Correct answer: Hyperoxygenate the patient

Hyperoxygenating the patient before suctioning is a crucial step to prevent hypoxemia, which can occur during the procedure due to the removal of oxygen from the airway. This action helps to maintain adequate oxygen saturation and minimize the risk of complications such as arrhythmias or cardiac arrest. It ensures the patient has a reserve of oxygen during the temporary interruption of ventilation.

Question 27: Which of the following signs is most concerning for impending brain herniation in a patient with traumatic brain injury?

Vomiting
Dilated, non-reactive pupils (Correct answer)
Headache
Restlessness and agitation

Correct answer: Dilated, non-reactive pupils

Dilated, non-reactive pupils, especially if unilateral, are a critical sign of impending brain herniation. This indicates compression of the oculomotor nerve (CN III) due to severe increased intracranial pressure, which is a neurological emergency. While restlessness, headache, and vomiting are also symptoms of increased ICP, dilated non-reactive pupils signify a more advanced and life-threatening stage of brain compression.

Question 28: In a patient with chronic obstructive pulmonary disease (COPD), which symptom suggests the need for hospitalization?

Barrel-shaped chest
Use of accessory muscles to breathe (Correct answer)
Cough with white sputum
Dyspnea on exertion

Correct answer: Use of accessory muscles to breathe

The use of accessory muscles to breathe signifies increased work of breathing and severe respiratory distress, indicating a significant exacerbation of COPD. This symptom suggests that the patient's respiratory system is struggling to maintain adequate oxygenation and ventilation. It is a critical sign requiring immediate medical attention and likely hospitalization to prevent respiratory failure.

Question 29: The nurse is caring for a patient admitted with Diabetic Ketoacidosis (DKA). The initial potassium level was 5.8 mEq/L. After several hours of treatment with intravenous fluids and an insulin infusion, the patient's potassium level is now 3.2 mEq/L. What is the nurse's priority action?

Continue to monitor the patient without intervention.
Administer intravenous potassium as ordered. (Correct answer)
Administer a dose of sodium polystyrene sulfonate (Kayexalate).
Decrease the rate of the insulin infusion.

Correct answer: Administer intravenous potassium as ordered.

Insulin therapy in DKA drives potassium from the extracellular fluid into the cells, which can lead to a rapid drop in serum potassium levels and cause hypokalemia. A potassium level of 3.2 mEq/L is low and requires replacement to prevent cardiac dysrhythmias and other complications. Administering potassium is the priority.

Question 30: What is the primary action of nitroglycerin when used in acute coronary syndrome (ACS)?

Decreases heart rate
Dilates coronary arteries (Correct answer)
Increases myocardial oxygen demand
Promotes platelet aggregation

Correct answer: Dilates coronary arteries

Nitroglycerin primarily acts as a vasodilator, relaxing smooth muscle in both veins and arteries, including the coronary arteries. In acute coronary syndrome, this dilation increases blood flow to the ischemic myocardium, improving oxygen supply. It also reduces preload by venous dilation, which decreases myocardial oxygen demand.

Question 31: Which intervention is most effective in preventing ventilator-associated pneumonia (VAP)?

Administering broad-spectrum antibiotics
Keeping the patient NPO
Elevating the head of bed to 30–45 degrees (Correct answer)
Suctioning every hour

Correct answer: Elevating the head of bed to 30–45 degrees

Elevating the head of the bed to 30-45 degrees (semi-recumbent position) is a cornerstone intervention for preventing ventilator-associated pneumonia (VAP). This position helps to reduce gastric reflux and the aspiration of oral and gastric secretions into the lungs, which are primary pathways for bacterial entry and subsequent pneumonia development in mechanically ventilated patients.

Question 32: A patient in septic shock has a MAP of 58 mmHg despite 2 liters of IV fluid. Which vasopressor is the first-line agent per Surviving Sepsis guidelines?

Phenylephrine
Norepinephrine (Correct answer)
Vasopressin
Epinephrine

Correct answer: Norepinephrine

Norepinephrine is the first-line vasopressor for septic shock per Surviving Sepsis Campaign guidelines due to its alpha-adrenergic effects.

Question 33: Which of the following best describes the mechanism of action of ACE inhibitors?

Inhibits conversion of angiotensin I to angiotensin II (Correct answer)
Blocks calcium channels in myocardial cells
Promotes reabsorption of sodium in renal tubules
Inhibits beta-adrenergic receptors

Correct answer: Inhibits conversion of angiotensin I to angiotensin II

ACE inhibitors (Angiotensin-Converting Enzyme inhibitors) block the enzyme responsible for converting angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor and stimulates aldosterone release, so inhibiting its formation leads to vasodilation, reduced blood pressure, and decreased fluid retention. This mechanism makes them effective in treating hypertension and heart failure.

Question 34: What is the correct sequence for donning personal protective equipment (PPE)?

Gown, mask, goggles, gloves (Correct answer)
Gloves, gown, mask, goggles
Gown, gloves, mask, goggles
Mask, gown, gloves, goggles

Correct answer: Gown, mask, goggles, gloves

The correct sequence for donning personal protective equipment (PPE) is designed to protect the healthcare worker from contamination, starting with the body and moving to the hands. Donning the gown first covers the body, followed by the mask and goggles for facial protection, and finally gloves as the last barrier for direct contact. This order ensures maximum protection and minimizes self-contamination.

Question 35: What is the primary concern when administering IV potassium chloride to a patient?

Renal insufficiency
Hypotension
Nausea and vomiting
Arrhythmias (Correct answer)

Correct answer: Arrhythmias

Administering IV potassium chloride too rapidly or in excessive amounts can lead to hyperkalemia, which significantly affects cardiac electrical activity. This can cause life-threatening arrhythmias, including bradycardia, heart block, and even cardiac arrest. Therefore, it must be administered slowly and carefully, often diluted, with close cardiac monitoring.

Question 36: Which of the following Glasgow Coma Scale (GCS) scores indicates moderate brain injury?

9–12 (Correct answer)
3–8
6–9
13–15

Correct answer: 9–12

The Glasgow Coma Scale (GCS) is a standardized neurological assessment tool used to measure a person's level of consciousness. A GCS score of 9–12 indicates a moderate brain injury, reflecting a significant but not severe impairment. Scores of 13–15 are considered mild, while 3–8 signify a severe brain injury, requiring close monitoring and intervention.

Question 37: Which medication is commonly used to reduce afterload in heart failure?

Furosemide
Metoprolol
Lisinopril (Correct answer)
Digoxin

Correct answer: Lisinopril

Lisinopril, an ACE inhibitor, reduces afterload by causing vasodilation, which decreases systemic vascular resistance. By lowering the resistance against which the heart must pump, it improves cardiac output and reduces the workload on the failing heart in patients with heart failure. This makes it a cornerstone medication for managing heart failure symptoms.

Question 38: Which of the following is a key nursing intervention for a patient admitted with a suspected pulmonary embolism (PE)?

Initiating a fluid bolus to improve cardiac output.
Encouraging frequent ambulation to improve circulation.
Administering anticoagulation therapy as ordered.
Placing the patient in a high Fowler's position. (Correct answer)

Correct answer: Placing the patient in a high Fowler's position.

Placing the patient in a high Fowler's position helps to maximize chest expansion and alleviate dyspnea, which is a common and distressing symptom of a pulmonary embolism. While anticoagulation is the cornerstone of treatment, immediate positioning to improve breathing is a critical initial nursing action. Ambulation is contraindicated as it could dislodge more clots. Fluid boluses should be given with caution as they can worsen right ventricular strain.

Question 39: Which medication is typically administered to reverse the effects of opioid overdose?

Atropine
Protamine sulfate
Naloxone (Correct answer)
Flumazenil

Correct answer: Naloxone

Naloxone is an opioid antagonist specifically used to rapidly reverse the effects of opioid overdose by blocking opioid receptors. It is a life-saving medication that can quickly restore respiratory function in patients experiencing opioid-induced respiratory depression. Its rapid action makes it the drug of choice for opioid overdose emergencies.

Question 40: Which of the following medications requires a peak and trough level for safe administration?

Vancomycin (Correct answer)
Azithromycin
Ciprofloxacin
Acetaminophen

Correct answer: Vancomycin

Vancomycin is an antibiotic with a narrow therapeutic index, meaning the difference between an effective and a toxic dose is small. Therefore, peak and trough levels are routinely monitored to ensure therapeutic concentrations are achieved while minimizing the risk of serious adverse effects such as nephrotoxicity (kidney damage) and ototoxicity (hearing damage).

Question 41: In assessing a patient with cholecystitis, which clinical sign is most commonly expected?

Left lower quadrant pain
Murphy’s sign (pain with inspiration during palpation of RUQ) (Correct answer)
Ascites
Hematochezia

Correct answer: Murphy’s sign (pain with inspiration during palpation of RUQ)

Cholecystitis is inflammation of the gallbladder, typically caused by gallstones obstructing the cystic duct. Murphy's sign is a classic clinical finding where a patient experiences sharp pain and inspiratory arrest when the examiner palpates the right upper quadrant (RUQ) beneath the liver edge during inspiration. This maneuver causes the inflamed gallbladder to descend and contact the examiner's hand, eliciting pain.

Question 42: A patient receiving morphine sulfate IV begins to experience respiratory depression. What is the most appropriate immediate intervention?

Increase IV fluid rate
Reposition the patient and observe
Administer naloxone (Correct answer)
Place in Trendelenburg position

Correct answer: Administer naloxone

Morphine sulfate is an opioid analgesic, and respiratory depression is a serious adverse effect. Naloxone is an opioid antagonist that rapidly reverses the effects of opioids by competing for receptor sites. Administering naloxone is the immediate and most appropriate intervention to counteract life-threatening respiratory depression.

Question 43: A patient with a history of heart failure is being discharged from the progressive care unit. The nurse is providing education on lifestyle modifications. Which statement by the patient indicates a need for further teaching?

"I will weigh myself every morning and call my doctor if I gain more than 3 pounds in a day."
"I need to make sure I take my medications every day, even if I am feeling better."
"I should limit my sodium intake to no more than 2,000 milligrams per day."
"I will try to drink at least 3 liters of water every day to stay hydrated." (Correct answer)

Correct answer: "I will try to drink at least 3 liters of water every day to stay hydrated."

Patients with heart failure are often on a fluid restriction to prevent volume overload. Encouraging a high fluid intake, such as 3 liters per day, would be contraindicated and indicates a need for further education. Daily weights, sodium restriction, and medication adherence are all key components of successful heart failure self-management.

Question 44: Which clinical manifestation is most concerning in a patient with suspected sepsis?

Heart rate of 88 bpm
White blood cell count of 11,000/mm³
Warm, flushed skin
Blood pressure 86/52 mmHg (Correct answer)

Correct answer: Blood pressure 86/52 mmHg

A blood pressure of 86/52 mmHg indicates hypotension, which is a critical sign of septic shock. Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Hypotension in sepsis signifies inadequate tissue perfusion and is a medical emergency requiring immediate fluid resuscitation and vasopressors to prevent irreversible organ damage and death.

Question 45: Which drug is commonly used for sedation in mechanically ventilated patients and has both anxiolytic and amnestic effects?

Propofol
Dexmedetomidine
Lorazepam
Midazolam (Correct answer)

Correct answer: Midazolam

Midazolam is a short-acting benzodiazepine commonly used for sedation in mechanically ventilated patients due to its rapid onset and relatively short duration of action. It provides both anxiolytic (anxiety-reducing) and amnestic (memory-impairing) effects, which are beneficial for patient comfort and tolerance of mechanical ventilation. Other options have different primary uses or side effect profiles.

Question 46: A nurse is caring for a patient who was recently extubated after several days of mechanical ventilation. Which of the following parameters is the BEST indicator of the patient's readiness to be weaned from mechanical ventilation?

PaO2 of 85 mmHg on FiO2 of 40%
Maximal inspiratory pressure (MIP) of -20 cm H2O
Tidal volume of 450 mL with a respiratory rate of 18 breaths/min
A rapid shallow breathing index (RSBI) of 95 (Correct answer)

Correct answer: A rapid shallow breathing index (RSBI) of 95

The rapid shallow breathing index (RSBI), which is the ratio of respiratory frequency to tidal volume (f/VT), is a strong predictor of weaning success. An RSBI of less than 105 is a commonly accepted parameter indicating that a patient is likely to be successfully weaned. The other values, while important, are not as comprehensively predictive as the RSBI.

Question 47: A 68-year-old male with a history of type 2 diabetes is admitted to the progressive care unit with altered mental status. His laboratory results show a blood glucose of 850 mg/dL, serum osmolality of 340 mOsm/kg, and a negative urine ketone test. Which of the following interventions is the highest priority?

Obtaining a STAT head CT scan.
Placing the patient on a cardiac monitor.
Initiating fluid resuscitation with an isotonic solution. (Correct answer)
Administering an intravenous insulin bolus.

Correct answer: Initiating fluid resuscitation with an isotonic solution.

The patient's presentation is consistent with Hyperosmolar Hyperglycemic State (HHS). The most critical initial intervention is aggressive fluid resuscitation to correct the profound dehydration and hyperosmolality, which are the primary causes of the altered mental status. While insulin will be administered, correcting the fluid deficit is the first priority to restore tissue perfusion.

Question 48: A progressive care patient has a platelet count of 18,000/mm³. Which intervention is the highest priority?

Administer aspirin for pain
Encourage ambulation
Initiate bleeding precautions (Correct answer)
Apply compression stockings

Correct answer: Initiate bleeding precautions

A platelet count below 20,000/mm³ carries a high risk of spontaneous bleeding, requiring immediate bleeding precautions.

Question 49: A patient with advanced heart failure has completed an advance directive designating 'comfort measures only.' The patient then loses decision-making capacity. The healthcare proxy requests aggressive interventions. The nurse should:

Proceed with aggressive interventions as directed by the healthcare proxy
Attempt to reverse the patient's loss of decision-making capacity before proceeding
Follow the patient's documented advance directive, which reflects the patient's previously expressed wishes (Correct answer)
Defer the decision entirely to the attending physician

Correct answer: Follow the patient's documented advance directive, which reflects the patient's previously expressed wishes

A valid advance directive reflects the patient's own autonomous wishes and takes precedence when the patient lacks decision-making capacity; a proxy cannot override a clearly documented prior competent decision.

Question 50: Which nursing intervention helps prevent complications of portal hypertension in a patient with cirrhosis?

Administering lactulose (Correct answer)
Encouraging high-protein intake
Restricting physical activity
Limiting fluid intake

Correct answer: Administering lactulose

Portal hypertension in cirrhosis can lead to hepatic encephalopathy due to the accumulation of ammonia and other toxins. Lactulose works by trapping ammonia in the gut and promoting its excretion through the stool, thereby reducing systemic ammonia levels. This intervention directly addresses a major complication of portal hypertension by preventing or treating hepatic encephalopathy.

Question 51: A progressive care nurse is educating a patient being discharged after an asthma exacerbation. Which statement by the patient indicates a need for further teaching?

"I will use my albuterol inhaler 15 minutes before I exercise."
"I should use my rescue inhaler more often if my symptoms get worse."
"I need to use my inhaled corticosteroid every day, even when I feel fine."
"If I feel short of breath, I will take my oral prednisone immediately." (Correct answer)

Correct answer: "If I feel short of breath, I will take my oral prednisone immediately."

Oral corticosteroids like prednisone are not rescue medications for acute shortness of breath. They are used for managing more severe, prolonged exacerbations, typically as a prescribed tapering course. The patient should have a clear action plan that involves using their short-acting beta-agonist (rescue inhaler) for acute symptoms and seeking medical attention if symptoms do not improve. The other statements demonstrate correct understanding of asthma self-management.

Question 52: When preparing to transfuse irradiated blood products, the nurse understands this measure prevents which complication?

Transfusion-associated graft-versus-host disease (Correct answer)
Hyperkalemia
Febrile non-hemolytic reaction
Allergic urticarial reaction

Correct answer: Transfusion-associated graft-versus-host disease

Irradiation inactivates donor T lymphocytes, preventing transfusion-associated graft-versus-host disease in immunocompromised patients.

Question 53: What is the primary goal of thrombolytic therapy in patients with acute myocardial infarction (MI)?

Prevent platelet aggregation
Reduce myocardial oxygen demand
Decrease heart rate
Dissolve the existing blood clot (Correct answer)

Correct answer: Dissolve the existing blood clot

The primary goal of thrombolytic therapy in acute myocardial infarction (MI) is to dissolve the blood clot (thrombus) that is obstructing blood flow in the coronary artery. By restoring blood flow (reperfusion) to the ischemic myocardial tissue, thrombolytics aim to limit infarct size, preserve cardiac function, and improve patient outcomes.

Question 54: Which assessment tool is specifically validated for measuring delirium in acute care settings?

Glasgow Coma Scale (GCS)
Montreal Cognitive Assessment (MoCA)
Confusion Assessment Method (CAM) (Correct answer)
Mini-Mental State Examination (MMSE)

Correct answer: Confusion Assessment Method (CAM)

The Confusion Assessment Method (CAM) is the gold-standard validated tool for delirium assessment in acute/progressive care; the CAM-ICU is adapted for non-verbal/intubated patients.

Question 55: A patient recovering from septic shock develops bilateral pulmonary infiltrates, PaO2/FiO2 ratio of 150, and respiratory failure without cardiac cause. The nurse recognizes this as:

Cardiogenic pulmonary edema
Pulmonary embolism
Acute respiratory distress syndrome (ARDS) (Correct answer)
Hospital-acquired pneumonia

Correct answer: Acute respiratory distress syndrome (ARDS)

Bilateral infiltrates, severe hypoxemia (P/F < 200), and non-cardiac etiology following sepsis meet the Berlin criteria for ARDS.

Question 56: Which lactate level is most consistent with significant tissue hypoperfusion in a critically ill patient?

4.5 mmol/L (Correct answer)
0.8 mmol/L
1.5 mmol/L
2.2 mmol/L

Correct answer: 4.5 mmol/L

A lactate ≥ 4 mmol/L indicates severe tissue hypoperfusion and is associated with increased mortality, meeting the threshold for septic shock workup.

Question 57: Which ECG change is commonly associated with hypokalemia?

Peaked T waves
U waves (Correct answer)
Prolonged QT interval
ST elevation

Correct answer: U waves

Hypokalemia, a low potassium level, commonly manifests on an ECG as the presence of U waves, which are small, positive deflections following the T wave. It can also cause flattened or inverted T waves and a prolonged QT interval. Peaked T waves, in contrast, are characteristic of hyperkalemia.

Question 58: A progressive care patient meets SIRS criteria and has a suspected infection. According to current definitions, this patient has:

Sepsis (Correct answer)
Bacteremia
Septic shock
SIRS without sepsis

Correct answer: Sepsis

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection; SIRS + infection meets the older sepsis definition and warrants treatment.

Question 59: Which parameter is most reliable in evaluating the effectiveness of oxygen therapy?

Capillary refill
SpO₂ level (Correct answer)
Respiratory rate
Lung sounds

Correct answer: SpO₂ level

The SpO₂ (pulse oximetry) level directly measures the percentage of hemoglobin saturated with oxygen in the arterial blood. It provides an immediate and objective assessment of oxygenation status and the effectiveness of oxygen therapy. While other parameters like respiratory rate and lung sounds are important, SpO₂ offers a direct physiological measure of how well the body is being oxygenated.

Question 60: The nurse notices that a patient who was previously cooperative has become withdrawn, stopped eating, and states 'nothing matters anymore.' These findings are MOST consistent with:

Physiologic response to pain medication
Delirium with hypoactive features
Normal adjustment to hospitalization
Clinical depression requiring further assessment and intervention (Correct answer)

Correct answer: Clinical depression requiring further assessment and intervention

Withdrawal, anhedonia (loss of interest), anorexia, and hopelessness are hallmark symptoms of clinical depression that require formal assessment using validated tools (e.g., PHQ-2/PHQ-9) and prompt intervention.

Question 61: Which condition is characterized by a sudden onset of sharp chest pain and dyspnea, often associated with a pneumothorax?

Pulmonary edema
Pleural effusion
Pneumothorax (Correct answer)
Pulmonary embolism

Correct answer: Pneumothorax

A pneumothorax is the presence of air in the pleural space, which causes the lung to collapse. This condition typically presents with a sudden onset of sharp, pleuritic chest pain (pain that worsens with breathing) and dyspnea (shortness of breath) as the lung's ability to expand is compromised. The other options have different primary presentations.

Question 62: A nurse caring for a patient with a nasogastric (NG) tube notes abdominal distention and high residual volumes. What is the priority nursing action?

Position the patient in supine
Flush the NG tube with air
Hold the feeding and notify the provider (Correct answer)
Increase the feeding rate

Correct answer: Hold the feeding and notify the provider

Abdominal distention and high residual volumes in a patient with an NG tube receiving feedings indicate delayed gastric emptying or intolerance to the feeding. Continuing the feeding could lead to aspiration, nausea, vomiting, or further abdominal discomfort. The priority is to stop the feeding to prevent complications and then notify the provider for further assessment and orders.

Question 63: Which of the following is a key differentiating feature between Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS)?

The degree of hyperglycemia
The presence of significant ketosis and metabolic acidosis (Correct answer)
The level of consciousness
The presence of severe dehydration

Correct answer: The presence of significant ketosis and metabolic acidosis

While both DKA and HHS involve hyperglycemia and dehydration, the hallmark of DKA is the presence of significant ketosis (leading to ketone bodies in the blood and urine) and a subsequent metabolic acidosis. In HHS, there is enough insulin to prevent ketosis, but not enough to prevent severe hyperglycemia.

Question 64: Which cranial nerve is responsible for pupillary constriction in response to light?

Cranial Nerve III (Oculomotor) (Correct answer)
Cranial Nerve VII (Facial)
Cranial Nerve V (Trigeminal)
Cranial Nerve II (Optic)

Correct answer: Cranial Nerve III (Oculomotor)

Cranial Nerve III, the Oculomotor nerve, is responsible for several eye movements, including pupillary constriction (miosis) in response to light. It carries parasympathetic fibers that innervate the sphincter pupillae muscle, causing the pupil to constrict. Cranial Nerve II (Optic) is responsible for vision, but not the motor function of pupillary constriction.

Question 65: Which medication is used to reverse the anticoagulant effects of warfarin in case of major bleeding?

Vitamin D
Vitamin K (Correct answer)
Idarucizumab
Protamine sulfate

Correct answer: Vitamin K

Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Therefore, in cases of major bleeding or significant overdose, administering Vitamin K (phytonadione) can reverse its anticoagulant effects by promoting the synthesis of these clotting factors. Protamine sulfate reverses heparin, and idarucizumab reverses dabigatran.

Question 66: Which intervention is MOST effective in preventing delirium in a progressive care patient?

Promoting sleep hygiene, early mobility, and reorientation strategies (Correct answer)
Providing continuous physical restraints to prevent falls
Keeping the room darkened and quiet at all times
Administering prophylactic haloperidol nightly

Correct answer: Promoting sleep hygiene, early mobility, and reorientation strategies

Non-pharmacologic bundles including sleep promotion, early mobilization, cognitive stimulation, and reorientation (e.g., ABCDEF bundle) are the most evidence-based approach to delirium prevention.

Question 67: Which intervention is a core component of sepsis bundle completion within 3 hours of identification?

Insert a central venous catheter
Initiate vasopressors immediately
Perform a lumbar puncture
Obtain blood cultures before antibiotics (Correct answer)

Correct answer: Obtain blood cultures before antibiotics

Obtaining blood cultures before antibiotic administration is a mandatory component of the Surviving Sepsis 1-hour bundle.

Question 68: A patient on heparin infusion has a PTT of 210 seconds (goal 60–100 seconds). What is the priority nursing action?

Administer vitamin K
Obtain a platelet count only
Hold the infusion and notify the provider (Correct answer)
Increase the heparin rate

Correct answer: Hold the infusion and notify the provider

A supratherapeutic PTT significantly above goal indicates over-anticoagulation; the infusion should be stopped and the provider notified immediately.

Question 69: A nurse assesses a tracheostomy patient and notes a sudden drop in oxygen saturation and the sound of air escaping. What should the nurse suspect?

Cuff leak or tracheostomy dislodgement (Correct answer)
Bronchospasm
Tracheal stenosis
Mucus plug

Correct answer: Cuff leak or tracheostomy dislodgement

A sudden drop in oxygen saturation combined with the sound of air escaping around a tracheostomy tube strongly suggests a problem with the cuff or the tube's position. A cuff leak means air is escaping past the cuff instead of going into the lungs, reducing ventilation. Dislodgement means the tube is no longer correctly positioned in the trachea, leading to ineffective ventilation and air leakage, both requiring immediate intervention.

Question 70: A patient with a known seizure disorder experiences a tonic-clonic seizure lasting 8 minutes. What is the priority nursing action?

Record the seizure activity in the chart
Prepare for lumbar puncture
Administer IV lorazepam (Correct answer)
Apply soft wrist restraints

Correct answer: Administer IV lorazepam

A tonic-clonic seizure lasting 8 minutes is considered status epilepticus, a medical emergency requiring immediate intervention to prevent brain damage. IV lorazepam is a benzodiazepine that is the first-line treatment to abort prolonged seizures by enhancing GABAergic inhibition in the brain. Administering it promptly is the priority to stop the seizure activity.

Question 71: Which action best reflects the ethical principle of justice in nursing?

Providing equal care and resources to all patients (Correct answer)
Choosing to help the family of a VIP patient first
Spending more time with the most agreeable patient
Prioritizing care based on who arrives first

Correct answer: Providing equal care and resources to all patients

The ethical principle of justice in nursing dictates that all patients should receive fair and equitable care, regardless of their background, socioeconomic status, or personal characteristics. This means distributing resources and care impartially and without discrimination. Prioritizing based on personal preference or arrival time does not align with justice.

Question 72: A patient with anemia has hemoglobin of 7.2 g/dL and reports dizziness with exertion. Which nursing intervention is the priority?

Encourage increased oral iron intake
Prepare for immediate blood transfusion
Assess activity tolerance and implement fall precautions (Correct answer)
Administer supplemental oxygen at 10 L/min

Correct answer: Assess activity tolerance and implement fall precautions

Dizziness related to anemia increases fall risk; assessing activity tolerance and implementing fall precautions is the immediate safety priority.

Question 73: Which action by the nurse demonstrates advocacy for a critically ill patient?

Avoiding conflict with the healthcare provider
Communicating the patient’s wishes to the care team (Correct answer)
Administering medications on time
Reassuring the patient’s family that everything is fine

Correct answer: Communicating the patient’s wishes to the care team

Patient advocacy involves speaking up for the patient, ensuring their rights are respected, and their needs and wishes are communicated effectively to the healthcare team. This empowers the patient, especially when they are critically ill and may not be able to advocate for themselves. Administering medications or reassuring family are important but do not solely define advocacy.

Question 74: A patient with a history of adrenal insufficiency presents with hypotension, weakness, and hyperpigmentation. What is the likely diagnosis?

Addisonian crisis (Correct answer)
Graves’ disease
Myxedema coma
Cushing syndrome

Correct answer: Addisonian crisis

Addisonian crisis is a severe, life-threatening emergency caused by acute adrenal insufficiency. The classic symptoms of hypotension, weakness, and hyperpigmentation, especially in a patient with a history of adrenal insufficiency, are indicative of this condition. These manifestations result from critical deficiencies in cortisol and aldosterone, leading to circulatory collapse and electrolyte imbalances.

Question 75: A patient with atrial fibrillation is started on warfarin. What is the primary lab value used to monitor its therapeutic effect?

Fibrinogen level
aPTT
Platelet count
INR (Correct answer)

Correct answer: INR

The International Normalized Ratio (INR) is the standard laboratory test used to monitor the therapeutic effect of warfarin. It measures the extrinsic pathway of coagulation and helps ensure the patient's blood is adequately thinned to prevent clots without increasing the risk of bleeding. Maintaining the INR within the therapeutic range is crucial for patient safety and efficacy.

Question 76: What is the most important early goal in managing hemorrhagic shock following trauma?

Control the source of bleeding (Correct answer)
Administer high-dose corticosteroids
Insert a pulmonary artery catheter
Achieve a MAP > 90 mmHg with crystalloid

Correct answer: Control the source of bleeding

Definitive hemorrhage control is the primary goal because ongoing blood loss cannot be corrected by fluid resuscitation alone.

Question 77: A patient with polycythemia vera is most at risk for which complication in the progressive care unit?

Spontaneous hemorrhage
Severe anemia
Thromboembolic events (Correct answer)
Opportunistic infections

Correct answer: Thromboembolic events

Polycythemia vera causes increased blood viscosity due to excess RBCs, significantly elevating risk for thrombosis and embolic events.

Question 78: A progressive care nurse is supporting the family of a patient who has just been told the prognosis is terminal. The family members are arguing among themselves and appear angry. The nurse should recognize this behavior as:

A normal grief response that may reflect denial, fear, and helplessness (Correct answer)
A sign that family members require psychiatric evaluation
A dysfunctional family dynamic requiring immediate social work referral
Evidence that the family has not been adequately informed of the diagnosis

Correct answer: A normal grief response that may reflect denial, fear, and helplessness

Anger and conflict among family members in crisis situations are common manifestations of grief and reflect normal emotional responses including helplessness, fear, and denial.

Question 79: A patient receiving a blood transfusion develops fever, chills, and flank pain 15 minutes after initiation. What is the nurse's first action?

Stop the transfusion immediately (Correct answer)
Administer acetaminophen
Slow the transfusion rate
Obtain a repeat type and crossmatch

Correct answer: Stop the transfusion immediately

Signs of a hemolytic transfusion reaction require immediate cessation of the transfusion to prevent life-threatening complications.

Question 80: What is the priority nursing action after inserting a nasogastric (NG) tube for feeding?

Ask the patient if they can feel the tube in their throat
Confirm placement with an abdominal X-ray (Correct answer)
Start the feeding immediately
Clamp the tube and reassess in 30 minutes

Correct answer: Confirm placement with an abdominal X-ray

Confirming nasogastric (NG) tube placement with an abdominal X-ray is the most reliable and gold standard method to ensure the tube is correctly positioned in the stomach or small intestine. This critical step prevents serious complications such as aspiration pneumonia if the tube were inadvertently placed in the lungs. Never initiate feeding until placement is radiographically confirmed.

Question 81: Which parameter best reflects the adequacy of oxygen delivery during resuscitation from shock?

Central venous oxygen saturation (ScvO2) > 70% (Correct answer)
Heart rate below 100 bpm
Blood pressure normalization
Urine output > 30 mL/hr alone

Correct answer: Central venous oxygen saturation (ScvO2) > 70%

ScvO2 > 70% indicates that tissues are receiving adequate oxygen relative to demand, reflecting successful resuscitation at the cellular level.

Question 82: Which hemodynamic profile is characteristic of early distributive (septic) shock?

Low SVR, high CO, low PCWP (Correct answer)
Low SVR, low CO, high PCWP
High SVR, high CO, normal PCWP
High SVR, low CO, high PCWP

Correct answer: Low SVR, high CO, low PCWP

Septic shock causes vasodilation (low SVR), compensatory high cardiac output, and low filling pressures (low PCWP) in early stages.

Question 83: A nurse forgets to document a dose of medication but gave it. What is the appropriate action?

Alter the MAR to show it was given earlier
Chart a late entry with the correct time and explanation (Correct answer)
Create a new entry with the current time
Ignore it to avoid getting in trouble

Correct answer: Chart a late entry with the correct time and explanation

If a medication was given but not documented, the nurse must make a late entry in the patient's chart. This entry should accurately reflect the time the medication was administered and include an concise explanation for the delay in documentation. This ensures the medical record is accurate and complete, reflecting the actual care provided and maintaining legal integrity.

Question 84: Which symptom is most specific for myocardial infarction (MI) in older adult women?

Crushing chest pain
Jaw pain and fatigue (Correct answer)
Bradycardia
Left arm numbness

Correct answer: Jaw pain and fatigue

Older adult women often experience atypical symptoms of myocardial infarction (MI) compared to the classic crushing chest pain. Their symptoms can be more subtle and non-specific, including unusual fatigue, shortness of breath, nausea, and pain in the jaw, neck, or back. Recognizing these atypical presentations is crucial for timely diagnosis and intervention in this population.

Question 85: A patient with severe asthma is prescribed methylprednisolone. Which nursing action is most appropriate when administering this medication?

Monitor blood glucose levels closely (Correct answer)
Encourage fluid restriction
Administer with grapefruit juice
Avoid giving with meals

Correct answer: Monitor blood glucose levels closely

Methylprednisolone is a corticosteroid, and a common and significant side effect of corticosteroids is hyperglycemia (elevated blood glucose levels). Nurses must closely monitor blood glucose, especially in patients with diabetes or those at risk, to manage this potential complication effectively. This monitoring helps prevent adverse outcomes related to uncontrolled blood sugar.

Question 86: A family member of a dying patient asks the nurse, 'Is my mother suffering?' The patient is unconscious and receiving palliative sedation. Which response best reflects palliative care principles?

"It's hard to say — she may still be aware of pain at some level."
"She is not suffering; the medications are keeping her comfortable and peaceful." (Correct answer)
"You should speak with the physician about your concerns."
"We cannot know for certain what she is experiencing."

Correct answer: "She is not suffering; the medications are keeping her comfortable and peaceful."

Palliative sedation is titrated to ensure comfort; reassuring the family that the patient is comfortable is accurate, compassionate, and consistent with palliative care goals.

Question 87: A patient is admitted with a diagnosis of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). The nurse would expect which of the following laboratory findings?

Hyponatremia and decreased serum osmolality (Correct answer)
Hypernatremia and increased serum osmolality
Hyponatremia and increased serum osmolality
Hypernatremia and decreased serum osmolality

Correct answer: Hyponatremia and decreased serum osmolality

In SIADH, there is an excessive release of antidiuretic hormone (ADH), leading to water retention by the kidneys. This results in a dilutional hyponatremia (low serum sodium) and a decreased serum osmolality because the excess water dilutes the blood solutes.

Question 88: When titrating a norepinephrine infusion for a patient in septic shock, the nurse's target MAP is:

50 mmHg
80 mmHg
65 mmHg (Correct answer)
55 mmHg

Correct answer: 65 mmHg

Surviving Sepsis guidelines recommend maintaining a MAP ≥ 65 mmHg as the initial resuscitation target for septic shock.

Question 89: Which finding in a patient with pneumonia requires immediate intervention?

Temperature of 101.2°F (38.4°C)
Productive cough with yellow sputum
New-onset confusion and restlessness (Correct answer)
Respiratory rate of 24 breaths per minute

Correct answer: New-onset confusion and restlessness

New-onset confusion and restlessness in a patient with pneumonia can indicate hypoxemia (low oxygen levels) or developing sepsis, especially in older adults. These are signs of worsening respiratory status or systemic compromise that require immediate assessment and intervention to prevent further deterioration. Other findings like cough and fever are expected with pneumonia but are less immediately concerning than acute neurological changes.

Question 90: The nurse is assessing a patient for alcohol withdrawal using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale. Which finding would indicate the most severe level of withdrawal?

Moderate tremor and nausea with a score of 15
Mild diaphoresis and anxiety with a score of 8
Tachycardia and hypertension only with a score of 10
Severe agitation, hallucinations, and seizures with a score of 22 (Correct answer)

Correct answer: Severe agitation, hallucinations, and seizures with a score of 22

A CIWA-Ar score ≥20 indicates severe withdrawal requiring aggressive pharmacologic intervention; scores with seizures and hallucinations represent the highest risk category.

Question 91: A nurse is caring for a patient with a chest tube. Which finding should be reported immediately?

Constant bubbling in the water seal chamber (Correct answer)
Drainage of 50 mL serosanguinous fluid in 2 hours
Gentle bubbling in the suction chamber
Intermittent tidaling in the water seal

Correct answer: Constant bubbling in the water seal chamber

Constant bubbling in the water seal chamber, especially if it's a new finding or persists after an initial air leak has resolved, indicates a persistent air leak in the chest tube system or from the patient's lung. This requires immediate investigation and intervention as it suggests ongoing air leakage from the pleural space or a problem with the tubing integrity. Gentle bubbling in the suction chamber is normal.

Question 92: Which breath sound is most commonly associated with fluid in the alveoli?

Fine crackles (Correct answer)
Wheezes
Rhonchi
Stridor

Correct answer: Fine crackles

Fine crackles, also known as rales, are short, high-pitched, popping sounds heard during inspiration. They are produced when collapsed alveoli or small airways suddenly open, often due to the presence of fluid. This makes them a characteristic finding in conditions like pulmonary edema or pneumonia where fluid accumulates in the alveoli.

Question 93: Which of the following best describes the nurse's role in supporting a patient's spiritual needs in the progressive care setting?

Referring all spiritual concerns to the patient's family to handle outside the hospital
Avoiding spiritual topics to maintain professional boundaries
Providing direct spiritual guidance and counseling based on the nurse's own religious beliefs
Assessing spiritual needs, facilitating access to chaplaincy services, and respecting the patient's beliefs without imposing the nurse's own (Correct answer)

Correct answer: Assessing spiritual needs, facilitating access to chaplaincy services, and respecting the patient's beliefs without imposing the nurse's own

Nurses assess and acknowledge spiritual needs using open, non-judgmental approaches and facilitate chaplaincy or other appropriate resources while respecting the patient's beliefs without imposing personal views.

Question 94: Which clinical finding is most indicative of heparin-induced thrombocytopenia (HIT)?

Platelet count drop of >50% after 5–14 days of heparin (Correct answer)
Platelet count of 400,000/mm³
Immediate platelet drop after first heparin dose
Bleeding from IV sites within 24 hours

Correct answer: Platelet count drop of >50% after 5–14 days of heparin

HIT classically presents with a >50% decline in platelets occurring 5–14 days after heparin exposure due to antibody formation.

Question 95: Which laboratory finding is most consistent with disseminated intravascular coagulation (DIC)?

Elevated platelets and normal PT
Low fibrinogen and elevated D-dimer (Correct answer)
Normal PTT and low INR
Elevated fibrinogen and low D-dimer

Correct answer: Low fibrinogen and elevated D-dimer

DIC is characterized by consumption of clotting factors and fibrinogen, along with elevated D-dimer from fibrinolysis.

Question 96: What is a priority nursing concern in a patient with suspected deep vein thrombosis (DVT)?

Fluid volume excess
Activity intolerance
Potential for pulmonary embolism (Correct answer)
Risk for bleeding

Correct answer: Potential for pulmonary embolism

Deep vein thrombosis (DVT) involves the formation of a blood clot in a deep vein, most commonly in the legs. The most serious and life-threatening complication of a DVT is a pulmonary embolism (PE), which occurs if a piece of the clot breaks off and travels to the lungs, obstructing blood flow. Therefore, preventing PE is the paramount concern in DVT management.

Question 97: A patient is brought to the unit with suspected adrenal crisis (Addisonian crisis). Which of the following assessment findings would be most consistent with this diagnosis?

Bradycardia, fluid overload, and hypokalemia
Tachycardia, hypertension, and hypercalcemia
Hypertension, hyperglycemia, and hypernatremia
Hypotension, hypoglycemia, and hyperkalemia (Correct answer)

Correct answer: Hypotension, hypoglycemia, and hyperkalemia

Adrenal crisis is a life-threatening condition caused by an acute deficiency of cortisol. The classic presentation includes severe hypotension (due to loss of vascular tone and volume), hypoglycemia (due to decreased gluconeogenesis), and hyperkalemia (due to aldosterone deficiency).

Question 98: A patient receiving IV heparin has an aPTT that is significantly above the therapeutic range. What is the appropriate reversal agent?

Desmopressin
Vitamin K
Protamine sulfate (Correct answer)
Fresh frozen plasma

Correct answer: Protamine sulfate

Protamine sulfate is the specific antidote for heparin overdose. It works by forming a stable complex with heparin, neutralizing its anticoagulant effects. When a patient's aPTT is significantly elevated above the therapeutic range, indicating excessive anticoagulation, protamine sulfate is administered to reverse the effects and reduce bleeding risk.

Question 99: A patient with immune thrombocytopenic purpura (ITP) has a platelet count of 10,000/mm³. Which finding would require the most urgent intervention?

Mild bruising on the arms
Sudden severe headache and altered mental status (Correct answer)
Prolonged bleeding after venipuncture
Petechiae on the lower extremities

Correct answer: Sudden severe headache and altered mental status

Sudden severe headache and altered mental status suggest intracranial hemorrhage, the most dangerous complication of severe thrombocytopenia.

Question 100: A patient on telemetry suddenly reports chest pain and shortness of breath. What should the nurse do first?

Notify the physician
Call respiratory therapy
Assess vital signs and cardiac monitor (Correct answer)
Increase oxygen flow rate

Correct answer: Assess vital signs and cardiac monitor

When a patient on telemetry reports acute symptoms like chest pain and shortness of breath, the priority is to immediately assess their physiological status. This involves checking vital signs and observing the cardiac monitor for any changes, which provides critical information to guide subsequent interventions. This rapid assessment allows the nurse to determine the severity of the situation and initiate appropriate care.

Question 101: When performing a neurologic assessment, what does decerebrate posturing indicate?

Mild brain injury
Midbrain or brainstem dysfunction (Correct answer)
Cervical spinal injury
Increased oxygenation

Correct answer: Midbrain or brainstem dysfunction

Decerebrate posturing, characterized by extension and internal rotation of the arms and extension of the legs, indicates severe damage to the brainstem, specifically below the red nucleus (midbrain or pons). It signifies a more severe brain injury than decorticate posturing and often suggests a poor prognosis. This posturing reflects significant neurological dysfunction.

Question 102: A 68-year-old male with a history of heart failure is admitted with a diagnosis of community-acquired pneumonia. He presents with a productive cough, fever of 38.9°C, and crackles in the right lower lobe. Which of the following orders should the nurse prioritize?

Administer PRN antipyretics.
Administer intravenous antibiotics.
Obtain blood and sputum cultures.
Titrate oxygen to maintain SpO2 > 92%. (Correct answer)

Correct answer: Titrate oxygen to maintain SpO2 > 92%.

While all orders are important, ensuring adequate oxygenation is the immediate priority according to the ABCs (Airway, Breathing, Circulation). Hypoxia is a common and life-threatening complication of pneumonia. Once oxygenation is stabilized, the nurse should proceed with obtaining cultures before administering antibiotics to ensure the correct pathogen is identified.

Question 103: A progressive care patient who has been hospitalized for 5 days becomes confused at night, attempts to pull out his IV, and reports seeing insects on the ceiling. Which condition does this presentation most likely indicate?

Hyponatremia
ICU/hospital-acquired delirium (Correct answer)
New-onset dementia
Psychotic depression

Correct answer: ICU/hospital-acquired delirium

Hospital-acquired delirium is characterized by acute onset of fluctuating confusion, disorientation, and perceptual disturbances, and is extremely common in progressive care patients.

Question 104: A patient admitted for cardiac monitoring discloses feelings of hopelessness and that life is not worth living. What is the nurse's priority action?

Reassure the patient that these feelings are normal after a cardiac event
Document the statement and notify the physician at the next scheduled rounding
Perform a structured suicidal ideation assessment and notify the care team immediately (Correct answer)
Administer an as-needed anxiolytic medication

Correct answer: Perform a structured suicidal ideation assessment and notify the care team immediately

Statements indicating hopelessness and passive suicidal ideation require immediate structured risk assessment and prompt notification of the multidisciplinary team to ensure patient safety.

Question 105: Which of the following hemodynamic parameters is most indicative of left ventricular preload?

Cardiac output (CO)
Pulmonary artery wedge pressure (PAWP) (Correct answer)
Systemic vascular resistance (SVR)
Central venous pressure (CVP)

Correct answer: Pulmonary artery wedge pressure (PAWP)

Pulmonary artery wedge pressure (PAWP), also known as pulmonary capillary wedge pressure (PCWP), is the most accurate hemodynamic parameter for estimating left ventricular preload. It reflects the pressure in the left atrium and, indirectly, the left ventricular end-diastolic pressure, which determines the stretch of the left ventricular muscle fibers before contraction. This measurement is crucial for assessing fluid status and cardiac function.

Question 106: In monitoring a patient with a myocardial infarction, which cardiac marker rises first?

BNP
Myoglobin (Correct answer)
CK-MB
Troponin I

Correct answer: Myoglobin

Myoglobin is one of the earliest cardiac markers to rise following myocardial injury, typically within 1-4 hours after symptom onset. While it is sensitive for muscle damage, it is not specific to cardiac muscle. Troponin I and CK-MB rise later but are more specific for myocardial damage.

Question 107: Which action is appropriate when administering IV potassium chloride?

Use a central line for concentrations above 10 mEq/hr (Correct answer)
Give with loop diuretics simultaneously
Administer via IV push for rapid replacement
Mix with dextrose 5% in water (D5W) only

Correct answer: Use a central line for concentrations above 10 mEq/hr

Intravenous potassium chloride is a high-alert medication that can cause severe irritation and damage to peripheral veins, especially at higher concentrations or rapid infusion rates. Therefore, concentrations exceeding 10 mEq/hr are typically administered via a central venous catheter. This allows for greater dilution and minimizes the risk of phlebitis, pain, and tissue damage.

Question 108: A patient is admitted with acute decompensated heart failure. Which medication class is most appropriate to reduce preload and relieve pulmonary congestion?

Calcium channel blockers
Loop diuretics (Correct answer)
ACE inhibitors
Beta blockers

Correct answer: Loop diuretics

Loop diuretics, such as furosemide, are highly effective in acute decompensated heart failure because they promote rapid diuresis. By inhibiting sodium and chloride reabsorption in the loop of Henle, they reduce circulating blood volume. This action directly decreases preload and alleviates pulmonary congestion, which are key goals in managing acute heart failure.

Question 109: Which action is most important when administering leukocyte-reduced blood products?

Ensure the product is used to prevent CMV transmission (Correct answer)
Administer slowly over 6 hours
Use a standard blood filter (170–260 microns)
Warm the blood to 40°C before infusion

Correct answer: Ensure the product is used to prevent CMV transmission

Leukocyte reduction reduces the risk of CMV transmission and febrile non-hemolytic reactions in at-risk patients.

Question 110: A progressive care nurse is caring for a patient who is 48 hours post-coronary artery bypass graft (CABG) surgery. The patient is hemodynamically stable and has been extubated. Which nursing intervention is crucial to prevent postoperative pulmonary complications?

Encouraging the use of an incentive spirometer and splinting the incision when coughing. (Correct answer)
Maintaining strict bed rest for 72 hours.
Administering cough suppressants to minimize incisional pain.
Limiting oral fluid intake to prevent fluid overload.

Correct answer: Encouraging the use of an incentive spirometer and splinting the incision when coughing.

Postoperative pulmonary complications, such as atelectasis and pneumonia, are significant risks after CABG surgery. Encouraging deep breathing and coughing is essential to keep the lungs clear. Using an incentive spirometer helps with deep breathing, and splinting the chest incision with a pillow provides support and reduces pain during coughing, making it more effective. Strict bed rest, cough suppression, and fluid restriction would increase the risk of pulmonary complications.

Question 111: Which of the following pain scales is most appropriate for use with a nonverbal, intubated patient?

Visual Analog Scale (VAS)
Numeric Rating Scale (NRS)
Behavioral Pain Scale (BPS) (Correct answer)
Wong-Baker FACES scale

Correct answer: Behavioral Pain Scale (BPS)

The Behavioral Pain Scale (BPS) is specifically designed for assessing pain in critically ill, nonverbal, and intubated patients. It evaluates observable behaviors such as facial expression, upper limb movements, and compliance with ventilation, providing an objective measure of pain when self-report is not possible. Other scales require verbal or cognitive ability.

Question 112: What principle of ethical practice is demonstrated by respecting a patient’s right to refuse treatment?

Fidelity
Autonomy (Correct answer)
Nonmaleficence
Justice

Correct answer: Autonomy

Autonomy is the ethical principle that respects an individual's right to make their own decisions about their healthcare, free from coercion. Allowing a patient to refuse treatment, even if it goes against medical advice, upholds their right to self-determination and their personal values. This principle is fundamental to patient-centered care.

Question 113: Which intervention is contraindicated in a patient with severe thrombocytopenia (platelets < 20,000/mm³)?

Soft toothbrush for oral hygiene
Stool softeners
Rectal temperature measurement (Correct answer)
IV saline lock for access

Correct answer: Rectal temperature measurement

Rectal procedures are contraindicated in severe thrombocytopenia due to the risk of rectal trauma and uncontrolled hemorrhage.

Question 114: A nurse is providing culturally competent care to a patient from a culture where direct eye contact is considered disrespectful. Which approach should the nurse take?

Defer all communication to a family member who acts as a cultural intermediary
Adapt communication style to avoid prolonged direct eye contact while continuing to provide complete care (Correct answer)
Insist on eye contact to ensure the patient is engaged and understands instructions
Avoid all eye contact and communicate only through written materials

Correct answer: Adapt communication style to avoid prolonged direct eye contact while continuing to provide complete care

Culturally competent care requires adapting communication practices — including non-verbal behaviors like eye contact — to respect cultural norms while still providing complete, individualized patient care.

Question 115: A trauma patient develops hypotension, distended neck veins, and absent breath sounds on the left. The nurse should prepare for:

Endotracheal intubation
Pericardiocentesis
Needle decompression of the left chest (Correct answer)
Immediate blood transfusion

Correct answer: Needle decompression of the left chest

Absent breath sounds with hypotension and JVD after trauma indicates tension pneumothorax requiring emergency needle decompression.

Question 116: Which laboratory result requires immediate reporting in a patient suspected of having thrombotic thrombocytopenic purpura (TTP)?

BUN of 22 mg/dL
Platelet count of 150,000/mm³
Peripheral smear showing schistocytes (Correct answer)
Hemoglobin of 11 g/dL

Correct answer: Peripheral smear showing schistocytes

Schistocytes (fragmented RBCs) on peripheral smear indicate microangiopathic hemolytic anemia, a hallmark finding of TTP.

Question 117: When a nurse admits a terminally ill patient who requests no life-prolonging treatment, the nurse should:

Call the physician to clarify advance directives (Correct answer)
Respect the verbal request as legal and stop all interventions
Inform the patient they must be resuscitated in all situations
Provide life-sustaining treatments until the DNR is written

Correct answer: Call the physician to clarify advance directives

A verbal request for no life-prolonging treatment is important, but it must be legally documented as an advance directive (e.g., DNR/DNI) to be actionable. The nurse's role is to ensure the patient's wishes are formally recognized and ordered by the physician, protecting both the patient's autonomy and the healthcare team legally. Calling the physician clarifies the patient's wishes and initiates the proper documentation process.

Question 118: Which of the following best reflects proper technique when inserting an indwelling urinary catheter in a female patient?

Use sterile gloves and sterile technique (Correct answer)
Insert catheter 1 inch beyond urine flow return
Inflate the balloon before advancing the catheter
Use clean gloves and clean technique

Correct answer: Use sterile gloves and sterile technique

Inserting an indwelling urinary catheter is a sterile procedure that requires the use of sterile gloves and strict sterile technique. This is crucial to prevent the introduction of microorganisms into the urinary tract, thereby minimizing the risk of catheter-associated urinary tract infections (CAUTIs). Maintaining sterility throughout the procedure is paramount for patient safety.

Question 119: Which finding would be most concerning in a patient with suspected bowel perforation?

Abdominal cramping
Hyperactive bowel sounds
Nausea
Rigid, board-like abdomen (Correct answer)

Correct answer: Rigid, board-like abdomen

A rigid, board-like abdomen is a classic sign of peritonitis, which is severe inflammation of the peritoneum, often caused by the leakage of gastrointestinal contents into the abdominal cavity due to bowel perforation. This finding indicates a medical emergency requiring immediate surgical intervention. Other symptoms like nausea and cramping are common but less specific for perforation.

Question 120: Which medication is most appropriate for treating increased intracranial pressure (ICP)?

Lorazepam
Mannitol (Correct answer)
Morphine sulfate
Amiodarone

Correct answer: Mannitol

Mannitol is an osmotic diuretic commonly used to treat increased intracranial pressure (ICP). It works by drawing fluid from the brain tissue into the vascular space, thereby reducing cerebral edema and ICP. This medication is crucial in neurocritical care to prevent secondary brain injury by maintaining adequate cerebral perfusion pressure. Other options like morphine or lorazepam are not primary treatments for ICP.

Question 121: A patient is admitted with an acute inferior wall myocardial infarction. The nurse should be most vigilant for the development of which of the following dysrhythmias?

Ventricular tachycardia
Atrial fibrillation
Sinus tachycardia
Atrioventricular (AV) block (Correct answer)

Correct answer: Atrioventricular (AV) block

An inferior wall myocardial infarction often involves the right coronary artery (RCA), which supplies blood to the atrioventricular (AV) node in the majority of the population. Ischemia or damage to the AV node can lead to conduction disturbances, such as first-degree, second-degree, or third-degree AV block. Therefore, the nurse must closely monitor the patient's ECG for signs of heart block.

Question 122: A patient with a history of benzodiazepine dependence is admitted for a non-related procedure. The nurse anticipates withdrawal symptoms will most likely begin:

After 72 hours regardless of the benzodiazepine used
12–24 hours after the last dose for short-acting agents and up to 5–7 days for long-acting agents (Correct answer)
Within 1–2 hours of last dose
Only if the patient has been using benzodiazepines for more than 10 years

Correct answer: 12–24 hours after the last dose for short-acting agents and up to 5–7 days for long-acting agents

Benzodiazepine withdrawal timing depends on the drug's half-life; short-acting agents (e.g., lorazepam) produce symptoms within 12–24 hours, while long-acting agents (e.g., diazepam) may not produce symptoms for several days.

Question 123: Which intervention is most appropriate for a patient with upper gastrointestinal bleeding and hematemesis?

Administering proton pump inhibitor (Correct answer)
Encouraging ambulation
Providing oral fluids
Initiating a high-fiber diet

Correct answer: Administering proton pump inhibitor

Upper gastrointestinal bleeding, especially with hematemesis, often results from conditions like peptic ulcers or erosions where stomach acid plays a significant role. Proton pump inhibitors (PPIs) reduce gastric acid secretion, which helps to stabilize the clot, prevent further bleeding, and promote healing of the gastric mucosa. This is a critical intervention to manage the underlying cause and prevent re-bleeding.

Question 124: A patient in the progressive care unit develops an acute kidney injury (AKI) following a severe hypotensive episode. Their urine output is 20 mL/hr, BUN is 45 mg/dL, and creatinine is 2.8 mg/dL. Which classification of AKI is most likely?

Chronic
Postrenal
Prerenal (Correct answer)
Intrarenal

Correct answer: Prerenal

Prerenal AKI is caused by decreased blood flow to the kidneys. A severe hypotensive episode leads to renal hypoperfusion. This is characterized by a high BUN to creatinine ratio (in this case >20:1 is suggested but not explicitly calculated without a baseline) and oliguria, as the kidneys attempt to conserve volume.

Question 125: A patient in the progressive care unit is being treated for a severe exacerbation of chronic obstructive pulmonary disease (COPD). Which of the following assessment findings would indicate the most urgent need for intervention?

Use of accessory muscles and a respiratory rate of 28 breaths/min
Oxygen saturation of 91% on 2L nasal cannula
Reports of increased sputum production and cough
Decreased level of consciousness and confusion (Correct answer)

Correct answer: Decreased level of consciousness and confusion

A decreased level of consciousness and confusion are signs of hypercapnia and severe respiratory distress, indicating impending respiratory failure. This is a life-threatening situation that requires immediate intervention, possibly including non-invasive or invasive mechanical ventilation. While the other options are concerning, they do not represent the same level of immediate threat as a change in mental status.
