RPN Infection Prevention and Control 5

Question 1

A nurse prepares to perform a urinary catheter insertion. Which action is essential to prevent CAUTI?

Accepted Answer

Maintain a closed drainage system and keep the bag below bladder level

Answer

A closed drainage system prevents retrograde bacterial entry, and keeping the bag below the bladder prevents reflux of contaminated urine.

Question 2

Which organism is the most common cause of healthcare-associated pneumonia?

Accepted Answer

Pseudomonas aeruginosa

Answer

Pseudomonas aeruginosa is one of the most common and difficult-to-treat causes of healthcare-associated and ventilator-associated pneumonia.

Question 3

A nurse is assigned to a patient in protective (reverse) isolation. What is the primary purpose of this precaution?

Accepted Answer

To protect a severely immunocompromised patient from external pathogens

Answer

Reverse isolation protects immunocompromised patients (e.g., those post-bone marrow transplant) from pathogens carried by visitors, staff, or the environment.

Question 4

When should the nurse perform hand hygiene according to WHO's Five Moments for Hand Hygiene?

Accepted Answer

Before patient contact, before an aseptic task, after body fluid exposure, after patient contact, and after contact with the patient's surroundings

Answer

WHO's Five Moments define all critical points during patient care where hand hygiene must occur to break the chain of infection.

Question 5

A nurse uses a reusable blood pressure cuff on a patient with VRE (vancomycin-resistant Enterococcus). What is required?

Accepted Answer

Dedicate the cuff to that patient only and disinfect before reassignment

Answer

Equipment used on a patient with VRE should be dedicated to that patient and properly disinfected before use on another patient to prevent cross-transmission.
