Saudi Prometric Nursing Infection Control and Saudi MOH Regulations 3 — Questions and Answers
Question 1: A patient on a surgical ward develops fever, chills, and hypotension 48 hours after placement of a urinary catheter. The nurse suspects CAUTI. What is the most important immediate nursing action?
- Obtain urine culture and blood cultures, notify physician, and monitor vital signs (Correct answer)
- Change the urinary catheter immediately
- Administer antipyretics and reassess in 4 hours
- Irrigate the bladder with normal saline
Correct answer: Obtain urine culture and blood cultures, notify physician, and monitor vital signs
Suspected CAUTI with systemic signs (fever, chills, hypotension) may indicate urosepsis — a medical emergency. Obtaining cultures (urine and blood) before antibiotics are started provides diagnostic information. Immediate physician notification and hemodynamic monitoring are critical.
Question 2: The nurse is performing surgical hand antisepsis before an operation. What is the minimum recommended duration for this procedure?
- 2–5 minutes using an antimicrobial scrub (or per manufacturer's instructions for alcohol-based formulations) (Correct answer)
- 30 seconds using alcohol-based hand rub
- 1 minute with soap and water
- 10 minutes using povidone-iodine
Correct answer: 2–5 minutes using an antimicrobial scrub (or per manufacturer's instructions for alcohol-based formulations)
Surgical hand antisepsis requires 2–5 minutes (or per the alcohol-based product manufacturer instructions) to remove transient flora and significantly reduce resident flora, achieving the 'clean' state required for surgical procedures. It differs from routine hand hygiene (20–30 sec).
Question 3: Which isolation precaution is required for a patient with active pulmonary tuberculosis?
- Airborne precautions with negative-pressure isolation room and N95 respirator (Correct answer)
- Droplet precautions with surgical mask
- Contact precautions with gown and gloves
- Standard precautions only
Correct answer: Airborne precautions with negative-pressure isolation room and N95 respirator
Pulmonary TB is spread via airborne droplet nuclei (<5 micrometers) that remain suspended in air. Airborne precautions require: negative-pressure (at least 6–12 air changes/hour), N95 or higher respirator for healthcare workers, and door kept closed.
Question 4: A nurse working in the ICU in Saudi Arabia is reviewing the ventilator-associated pneumonia (VAP) prevention bundle. Which intervention has the strongest evidence for VAP reduction?
- Head-of-bed elevation 30–45 degrees and oral care with chlorhexidine (Correct answer)
- Routine ventilator circuit changes every 48 hours
- Prophylactic antibiotics for all ventilated patients
- Daily routine suctioning whether secretions are present or not
Correct answer: Head-of-bed elevation 30–45 degrees and oral care with chlorhexidine
The VAP bundle with strongest evidence includes: head-of-bed elevation 30–45 degrees (prevents aspiration), oral care with 0.12% chlorhexidine (reduces oral colonization), daily sedation vacations, and assessment for extubation. Routine circuit changes increase VAP risk.
Question 5: The Saudi MOH regulations require healthcare workers to report occupational blood or body fluid exposures within what time frame?
- Immediately or as soon as possible — within hours, not days (Correct answer)
- Within 48 hours
- Within 72 hours, before starting PEP
- Within 1 week
Correct answer: Immediately or as soon as possible — within hours, not days
Occupational exposure to blood/body fluids requires immediate reporting to the occupational health department because post-exposure prophylaxis (PEP) for HIV must begin within 2 hours (maximum 72 hours) to be effective. Immediate reporting enables timely decision-making.
Question 6: A nurse notes that a patient's blood culture has grown MRSA. Which precautions should be implemented?
- Contact precautions (gown and gloves) for all patient care activities (Correct answer)
- Airborne precautions only
- Droplet precautions with surgical mask
- No additional precautions beyond standard precautions
Correct answer: Contact precautions (gown and gloves) for all patient care activities
MRSA (methicillin-resistant Staphylococcus aureus) is transmitted primarily through direct skin-to-skin contact and contact with contaminated surfaces. Contact precautions (gown and gloves for all patient contact) are required in addition to standard precautions.
A patient on a surgical ward develops fever, chills, and hypotension 48 hours after placement of a urinary catheter.
The nurse suspects CAUTI.
