Saudi Prometric Nursing Infection Control and Saudi MOH Regulations 4

Question 1

The nurse is cleaning and disinfecting a blood spill on the floor. What is the correct sequence?

Accepted Answer

Put on PPE, remove gross contamination with absorbent material, then disinfect with appropriate agent (e.g., 0.5% sodium hypochlorite)

Answer

Blood spill management: PPE first (protect self), then remove gross soiling using paper towels/absorbent material (never bare hands), then apply approved disinfectant (0.5% sodium hypochlorite/bleach), allow contact time, and dispose of waste as clinical waste.

Question 2

A hospital is implementing a healthcare-associated infection (HAI) surveillance program. Which calculation is used to measure the CAUTI rate for reporting purposes?

Accepted Answer

(CAUTI events / Urinary catheter days) × 1,000

Answer

The CAUTI rate is expressed per 1,000 catheter-days — not per patient or admission — because the risk of infection is proportional to the duration of catheterization. This standardized measure allows benchmarking between facilities and over time.

Question 3

What is the required contact time for a 1,000 ppm sodium hypochlorite (bleach) solution to be effective against HIV, hepatitis B, and standard bacteria?

Accepted Answer

At least 1 minute contact time

Answer

For blood/body fluid spills, 0.1% (1,000 ppm) sodium hypochlorite requires at least 1 minute of contact time to kill HIV and hepatitis B virus. For C. difficile spores, a higher concentration (5,000 ppm/0.5%) with longer contact time is needed.

Question 4

The nurse is preparing the patient's room after discharge for terminal cleaning. Which surfaces are highest priority?

Accepted Answer

High-touch surfaces: bed rails, call button, IV pole, light switches, door handles

Answer

High-touch surfaces in the patient environment harbor the most pathogens and are highest priority for terminal (discharge) cleaning. These include bed rails, call buttons, IV poles, light switches, door handles, faucets, and tray tables. Thorough cleaning of these surfaces significantly reduces pathogen transmission.

Question 5

A nurse is caring for a patient with a Vancomycin-Resistant Enterococcus (VRE) infection. When should contact precautions be discontinued?

Accepted Answer

After three consecutive negative cultures from relevant sites, per institutional policy

Answer

For VRE, contact precautions are typically continued until three consecutive negative cultures (stool/rectal swabs) are obtained from appropriate sites, at least one week apart, demonstrating decolonization. Institutional policy may specify additional criteria.
