RPN - Registered Practical Nurse Infection Prevention and Control Questions and Answers

Question 1

An RPN is caring for a client with a confirmed Clostridioides difficile (C. difficile) infection. In addition to using a private room, which of the following infection control measures are essential?

Accepted Answer

Wearing a gown and gloves, and performing hand hygiene with soap and water.

Answer

Clostridioides difficile requires Contact Precautions, which includes wearing a gown and gloves. Crucially, C. difficile produces spores that are resistant to alcohol-based hand rubs. Therefore, hand hygiene must be performed with soap and water to mechanically remove the spores.

Question 2

An RPN is preparing to perform a sterile dressing change. After opening the sterile tray on the bedside table, the RPN turns away from the field to retrieve a bottle of saline from a supply cart. What is the most appropriate next action?

Accepted Answer

Discard the current sterile field and prepare a new one.

Answer

A fundamental principle of surgical asepsis is that a sterile field must always be kept in sight. Turning your back on a sterile field renders it contaminated because you cannot ensure its sterility was maintained. The only safe and correct action is to discard the compromised field and set up a new one.

Question 3

Which of the following actions by an RPN is the MOST effective way to break the chain of infection at the 'mode of transmission' link?

Accepted Answer

Performing diligent hand hygiene between all client encounters.

Answer

Hand hygiene is the single most effective intervention to break the chain of infection by interrupting the mode of transmission. It prevents the transfer of microorganisms from the healthcare provider's hands to clients or between clients. Immunizations target the 'susceptible host', antibiotics target the 'infectious agent', and a dressing targets the 'portal of exit'.

Question 4

An RPN must enter the room of a client on Droplet Precautions for influenza. What is the minimum Personal Protective Equipment (PPE) required for routine care?

Accepted Answer

A procedure/surgical mask and eye protection.

Answer

Droplet Precautions are required for pathogens transmitted by large respiratory droplets, such as influenza. When working within 2 meters of the client, the RPN must wear a procedure/surgical mask and eye protection (goggles or face shield) to protect the mucous membranes of the eyes, nose, and mouth from splashes or sprays. A gown and gloves would also be required based on a point-of-care risk assessment for contact with body fluids.

Question 5

According to the principles of Routine Practices, when is it mandatory for an RPN to perform hand hygiene?

Accepted Answer

Before initial client contact and after contact with the client's environment.

Answer

Routine practices include the 4 Moments for Hand Hygiene. Key moments include before initial patient/client contact and after contact with the patient/client or their environment. Hand hygiene is required at many other points as well, including after removing gloves and before a clean/aseptic procedure, but this answer choice captures two of the most fundamental mandatory moments.
