LVN Infection Control & Safety Practices 4

Question 1

Which patient scenario represents the highest risk for developing a healthcare-associated infection (HAI)?

Accepted Answer

An 80-year-old with an indwelling urinary catheter on broad-spectrum antibiotics

Answer

Invasive devices, advanced age, and antibiotic use are major HAI risk factors that compound each other in the elderly patient.

Question 2

The nurse observes a colleague reusing a single-use item on a second patient. What is the appropriate response?

Accepted Answer

Report the observation to the charge nurse or supervisor

Answer

Reuse of single-use items violates infection control policy and patient safety standards; reporting to a supervisor ensures immediate corrective action.

Question 3

Which cleaning agent is the gold standard for eliminating C. difficile spores from environmental surfaces?

Accepted Answer

Diluted bleach solution (1:10)

Answer

C. difficile spores are resistant to alcohol and most disinfectants; a 1:10 bleach (sodium hypochlorite) solution is sporicidal and recommended by the CDC.

Question 4

A nurse prepares to change a central line dressing. Which action is essential to maintain aseptic technique?

Accepted Answer

Apply sterile drape and don sterile gloves before touching the insertion site

Answer

Central line dressing changes require sterile technique, including a sterile field, sterile drape, and sterile gloves, to prevent catheter-related bloodstream infections.

Question 5

Which statement about the chain of infection is correct?

Accepted Answer

Breaking any single link in the chain prevents infection transmission

Answer

Infection transmission requires all links in the chain to be intact; interrupting any single link — portal of exit, transmission, or susceptible host — stops the process.
