✍️ 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.

What Practice Test Geeks adds beyond an AI chat for FCCS
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length FCCS mock exam — 50 questions in 60 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed FCCS question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable FCCS cheat sheet you can print or save as a PDF.
- FCCS flashcards built from the same question bank.
- Free FCCS practice tests with the correct answer shown after each question.
