PCCN Medical Conditions & Symptoms — Questions and Answers
Question 1: Which clinical manifestation is most concerning in a patient with suspected sepsis?
- Warm, flushed skin
- Blood pressure 86/52 mmHg (Correct answer)
- White blood cell count of 11,000/mm³
- Heart rate of 88 bpm
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 2: A diabetic patient presents with fruity-smelling breath, confusion, and rapid, deep respirations. Which condition should the nurse suspect?
- Hypoglycemia
- Hyperosmolar hyperglycemic syndrome (HHS)
- Diabetic ketoacidosis (DKA) (Correct answer)
- Metabolic alkalosis
Correct answer: Diabetic ketoacidosis (DKA)
Diabetic ketoacidosis (DKA) is a severe complication of diabetes characterized by hyperglycemia, metabolic acidosis, and the presence of ketones. The classic signs include fruity-smelling breath (due to acetone), confusion (due to acidosis and dehydration), and Kussmaul respirations (rapid, deep breathing) as the body attempts to compensate for the acidosis.
Question 3: Which symptom is most specific for myocardial infarction (MI) in older adult women?
- Crushing chest pain
- Left arm numbness
- Jaw pain and fatigue (Correct answer)
- Bradycardia
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 4: Which electrolyte imbalance is most associated with mental status changes and muscle cramps?
- Hypernatremia
- Hyponatremia (Correct answer)
- Hyperkalemia
- Hypocalcemia
Correct answer: Hyponatremia
Hyponatremia, a low serum sodium level, significantly affects neurological function because sodium is critical for nerve impulse transmission and maintaining fluid balance in brain cells. Symptoms often include mental status changes such as confusion, lethargy, and disorientation, as well as muscle cramps, weakness, and seizures in severe cases.
Question 5: What is a priority nursing concern in a patient with suspected deep vein thrombosis (DVT)?
- Activity intolerance
- Risk for bleeding
- Potential for pulmonary embolism (Correct answer)
- Fluid volume excess
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 6: A patient with chronic kidney disease reports nausea, fatigue, and a metallic taste. Which lab result supports uremia?
- Creatinine 0.9 mg/dL
- BUN 80 mg/dL (Correct answer)
- Hematocrit 42%
- Sodium 140 mEq/L
Correct answer: BUN 80 mg/dL
Uremia is a syndrome of symptoms and signs associated with severe kidney failure, resulting from the accumulation of nitrogenous waste products in the blood. A significantly elevated Blood Urea Nitrogen (BUN) level, such as 80 mg/dL (normal range typically 7-20 mg/dL), is a key indicator of impaired kidney function and the presence of uremia, correlating with symptoms like nausea, fatigue, and a metallic taste.
Question 7: 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 8: Which sign is most associated with increased intracranial pressure (ICP)?
- Tachycardia
- Hypotension
- Widening pulse pressure and bradycardia (Correct answer)
- Diaphoresis
Correct answer: Widening pulse pressure and bradycardia
Widening pulse pressure and bradycardia are two key components of Cushing's triad, which is a classic physiological response to increased intracranial pressure (ICP). Cushing's triad also includes irregular respirations. These signs indicate the body's attempt to maintain cerebral perfusion in the face of rising ICP, making them critical indicators of neurological deterioration.
Question 9: In a patient with chronic obstructive pulmonary disease (COPD), which symptom suggests the need for hospitalization?
- Cough with white sputum
- Dyspnea on exertion
- Use of accessory muscles to breathe (Correct answer)
- Barrel-shaped chest
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.
