✍️ Sample PCCN Questions & Answers
1. 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?
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.
2. 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:
Bilateral infiltrates, severe hypoxemia (P/F < 200), and non-cardiac etiology following sepsis meet the Berlin criteria for ARDS.
3. In a patient with chronic obstructive pulmonary disease (COPD), which symptom suggests the need for hospitalization?
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.
4. A patient with a spinal cord injury at the level of T4 is at risk for which potentially life-threatening complication?
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.
5. A nurse is caring for a patient experiencing opioid withdrawal. Which cluster of symptoms should the nurse expect?
Opioid withdrawal produces a hyperadrenergic state characterized by tachycardia, diaphoresis, piloerection (goosebumps), yawning, lacrimation, and muscle aches.
6. A patient with liver cirrhosis is at risk for hepatic encephalopathy. Which assessment finding most supports this diagnosis?
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.
