1. When should prophylactic antibiotics usually be given to reduce the risk of surgical site infection?
- A. On the day before surgery with the evening meal
- B. For 7 days after surgery to cover the healing period
- C. Within 60 minutes before the surgical incision
- D. Only after the wound has been closed
Show answer and rationale
Surgical antibiotic prophylaxis is given within 120 minutes, and usually within 60 minutes, before incision so that tissue levels are adequate when the skin is opened. Prolonged postoperative prophylaxis is not recommended.
Reference: WHO Global Guidelines for the Prevention of Surgical Site Infection
2. A patient is diagnosed with scabies. Which type of transmission-based precautions should the nurse implement?
- A. Contact precautions
- B. Standard precautions only, with no additional measures
- C. Airborne precautions
- D. Droplet precautions
Show answer and rationale
Scabies mites spread by direct skin-to-skin contact and via contaminated linen and clothing, so contact precautions are required.
Reference: CDC Guideline for Isolation Precautions – Appendix A
3. What is the minimum level of reprocessing required for a semi-critical item, such as a flexible endoscope that contacts mucous membranes?
- A. High-level disinfection
- B. Low-level disinfection
- C. Cleaning with detergent only
- D. Rinsing with tap water
Show answer and rationale
Semi-critical items contact mucous membranes or non-intact skin and require at least high-level disinfection, which kills all microorganisms except large numbers of bacterial spores.
Reference: CDC Guideline for Disinfection and Sterilization in Healthcare Facilities
4. Which PPE is required, in addition to standard precautions, when caring for a patient on droplet precautions?
- A. A surgical mask worn on entering the room
- B. A powered air-purifying respirator
- C. A gown and gloves for all contact
- D. An N95 respirator worn at all times in the room
Show answer and rationale
Droplet precautions require a surgical (medical) mask for close contact, typically put on when entering the room. Respirators are required for airborne precautions.
Reference: CDC Guideline for Isolation Precautions – droplet precautions
5. A glass specimen tube containing blood breaks on the floor. What is the priority safety action when cleaning it up?
- A. Collect the glass pieces carefully by hand while wearing gloves
- B. Sweep the glass into the general waste bin first
- C. Pick up the broken glass with forceps or a scoop, not with the hands
- D. Pour disinfectant over the area and wait an hour before touching it
Show answer and rationale
Broken glass contaminated with blood is a sharps hazard; it must never be picked up by hand, even when wearing gloves, but with mechanical means such as forceps or a scoop and placed in a sharps container.
Reference: CDC Standard Precautions – sharps safety
Study tip
Learn which diseases need which precautions (for example TB, measles and varicella are airborne). Questions often hinge on that single fact.
