A patient who has been placed on contact precautions for Clostridium difficile (C. difficile) asks you to explain what he should know about this organism. Which statements made by the patient show an understanding of the patient teaching? Select all that apply

Correct use and reuse of PPE depends on the type of equipment, the level of contamination, and the nature of patient care. In some situations, certain PPE items may be reused for the same client during a single shift-but only if not visibly soiled, damaged, or contaminated.

Rationale for correct answer:

A. Goggles provide eye protection and are typically made of durable materials that can withstand cleaning and disinfection. When used for the same client, they may be reused during a shift as long as they are not visibly soiled or contaminated.

Rationale for incorrect answers:

B. Gowns, especially disposable ones, are single-use and should be removed after each client contact. Even with the same client, gowns can become contaminated with body fluids, increasing the risk of cross-contamination to the environment or nurse.

C. Surgical masks are single-use items. Prolonged use can lead to moisture buildup, reducing effectiveness. Masks should be discarded after removal or if they become damp or contaminated.

D. Clean gloves must be changed between tasks and after contact with potentially infectious material, even when caring for the same client. Reusing gloves increases the risk of spreading pathogens between clean and contaminated body sites.

Take home points:

• Goggles are the only PPE in this list that can be safely reused for the same client during a shift.
• Gloves, gowns, and surgical masks are considered single-use and should never be reused due to the high risk of cross-contamination.

Preventing the spread of infection involves understanding and interrupting the chain of infection, which includes six links: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

Rationale for correct answer:

B. Block the portal of exit from the reservoir: The most effective way to prevent transmission from a chronic carrier is by preventing the infectious agent from leaving the body. This includes using standard and transmission-based precautions.

Rationale for incorrect answers:

A. Eliminate the reservoir: While eliminating the reservoir (i.e., the source of infection) would be ideal, it is not always feasible in chronic carriers, as the host is the reservoir. Chronic carriers often cannot be cured completely, so this strategy is limited in practice.

C. Block the portal of entry into the host: This is a reactive measure focused on the next host, not the source, and does not address the spread from the chronic carrier.

D. Decrease the susceptibility of the host: Strengthening the immune system (e.g., through vaccination or proper nutrition) can help reduce a host’s risk of infection. However, this does not stop the chronic carrier from exposing others.

Take home points:

• Understanding the chain of infection helps nurses implement targeted interventions.
• When managing a client who is a chronic carrier, the most critical infection control strategy is to block the portal of exit to prevent the pathogen from reaching others.
