✍️ Sample FCCS Questions & Answers
1. Catheter-associated urinary tract infection (CAUTI) prevention is best achieved by:
The most effective CAUTI prevention measure is daily reassessment and prompt removal of urinary catheters when no longer clinically indicated.
2. In diabetic ketoacidosis (DKA), why may serum potassium appear normal or elevated despite total body potassium depletion?
Metabolic acidosis drives hydrogen ions into cells in exchange for potassium moving out, falsely elevating serum potassium despite total body depletion.
3. A patient with decompensated heart failure and hyponatremia (Na = 128 mEq/L) presents to the ICU. What is the most appropriate initial fluid management?
Dilutional hyponatremia in heart failure is treated with free water restriction and diuresis; adding more fluid worsens volume overload without correcting sodium.
4. A patient's SpO2 drops from 96% to 88% after suctioning. What is the best immediate action?
After suctioning, reconnecting to supplemental oxygen and temporarily increasing FiO2 rapidly corrects hypoxemia caused by the interruption of ventilation.
5. A pressure injury (bedsore) in the ICU is best prevented by repositioning patients every how many hours?
Repositioning every 2 hours redistributes pressure over bony prominences, preventing ischemic skin breakdown and pressure injury development.
6. Which of the following are common initial settings for mechanical ventilation in an adult with acute respiratory distress syndrome (ARDS)?
For adults with Acute Respiratory Distress Syndrome (ARDS), a lung-protective ventilation strategy is crucial, which includes a low tidal volume of 4-6 mL/kg of predicted body weight. This setting minimizes volutrauma and barotrauma to the fragile lungs, preventing further injury and improving outcomes. High tidal volumes can overdistend damaged alveoli, exacerbating lung injury.
