- Daily sedation holidays
- Routine antibiotic prophylaxis
- Frequent repositioning and head-of-bed elevation (Correct answer)
- Early extubation
Correct answer: Frequent repositioning and head-of-bed elevation
Ventilator-associated pneumonia (VAP) is a serious complication in mechanically ventilated patients. Frequent repositioning helps prevent atelectasis and promotes secretion clearance, while elevating the head of the bed (typically 30-45 degrees) reduces the risk of aspiration of gastric contents or oropharyngeal secretions into the lungs. These simple, evidence-based interventions are cornerstones of VAP prevention bundles.
Question 102: The Fick equation is primarily used to calculate which hemodynamic parameter?
- Cardiac output (Correct answer)
- Stroke volume variation
- Mean arterial pressure
- Pulmonary vascular resistance
Correct answer: Cardiac output
The Fick equation calculates cardiac output by dividing oxygen consumption (VO2) by the arteriovenous oxygen content difference (CaO2 – CvO2).
Question 103: When should empiric antibiotics be de-escalated in a septic ICU patient?
- Only after the patient is extubated
- Once procalcitonin normalizes below 0.5 ng/mL
- Once culture results identify the pathogen and sensitivities (Correct answer)
- After 24 hours regardless of culture results
Correct answer: Once culture results identify the pathogen and sensitivities
De-escalation should occur once culture results identify the causative organism and its sensitivities, allowing narrow-spectrum therapy.
Question 104: A critically ill patient has serum sodium of 118 mEq/L and is having seizures. What is the immediate treatment?
- Restrict free water to 1 L/day
- Administer 3% hypertonic saline IV (Correct answer)
- Give oral sodium chloride tablets
- Initiate slow continuous venovenous hemofiltration
Correct answer: Administer 3% hypertonic saline IV
Symptomatic severe hyponatremia with seizures requires immediate 3% hypertonic saline to raise sodium by 1-2 mEq/L/hr until symptoms resolve.
Question 105: What makes a professional competent in Pharmacology?

- Increase FiO2 to 1.0
- Immediately return to supine position
Correct answer: Assess endotracheal tube position and secretion clearance
Endotracheal tube displacement and secretion accumulation are the most common reversible causes of oxygenation decline during prone positioning and should be assessed first.
Question 107: A patient with severe sepsis has a central venous oxygen saturation (ScvO2) of 58%. What does this indicate?
- Hyperoxic state from excessive FiO2
- Excessive oxygen consumption relative to delivery (Correct answer)
- Normal venous return
- Adequate oxygen delivery to tissues
Correct answer: Excessive oxygen consumption relative to delivery
ScvO2 below 70% indicates the tissues are extracting more oxygen than normal, reflecting inadequate oxygen delivery relative to demand.
Question 108: A critically ill patient on CRRT requires anticoagulation. Which agent is preferred to minimize systemic bleeding risk?
- Regional citrate anticoagulation (Correct answer)
- Low-molecular-weight heparin
- Systemic unfractionated heparin
