The nurse recognizes that teaching a client to wash the hands after using the bathroom is an attempt to break the chain of infection between the:

infectious agent and reservoir.

portal of exit and mode of transmission.

mode of transmission and portal of entry.

susceptible host and infectious agent.

Answer and Explanation

The Correct Answer is C

A.   This option refers to the pathogens themselves (infectious agents) and the places where they live and multiply (reservoirs). Washing hands does not directly affect the relationship between these two.
B.   The portal of exit refers to how an infectious agent leaves the reservoir (e.g., through feces, urine, etc.), and the mode of transmission refers to how the agent spreads (e.g., via hands, surfaces, etc.). Handwashing helps reduce the potential for pathogens to be transmitted but does not specifically break the chain between these two links.
C.   Handwashing after using the bathroom effectively breaks the chain of infection by interrupting the mode of transmission (direct contact with contaminated hands) and preventing pathogens from entering another person's body (portal of entry). By cleaning hands, the risk of spreading infectious agents to others is significantly reduced.

D.   This option refers to the relationship between a person who is vulnerable to infection (susceptible host) and the pathogens that cause disease (infectious agents). While handwashing helps prevent infections, it primarily acts on the transmission aspect rather than directly affecting susceptibility.

This is the expected peak time for regular insulin. After administration, insulin will generally reach its maximum effectiveness in lowering blood glucose within this timeframe, making it crucial for the client to eat or take carbohydrates to prevent hypoglycemia.

A. Change the dressing B. Notify the physician C. Lower the head of the bed D. Mark the area of drainage, time and date

Correct Answer is D

Explanation

A. While it is important to maintain a clean and dry dressing, changing it immediately may not be necessary at this stage. The small amount of bloody drainage could be a normal postoperative finding, and changing the dressing could disturb the surgical site.
B. While it is important to keep the physician informed of any changes, in this case, a small amount of bloody drainage may not warrant immediate notification unless it becomes excessive or is accompanied by other concerning symptoms.
C. Lowering the head of the bed might not directly address the situation. It may be more appropriate if the patient shows signs of hypotension or distress, but there is no indication that the drainage has caused such a concern at this moment.
D. Marking the area of drainage allows for proper monitoring of the situation. It helps track whether the drainage increases, remains the same, or decreases over time. Documentation of the time and date also provides a clear record for the healthcare team regarding the postoperative course, which is essential for ongoing assessment.
