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.
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.

Correct Answer is C
Explanation
A. While anxiety can exacerbate feelings of breathlessness, treating anxiety does not address the
underlying issue of respiratory distress. It is important to first stabilize the client’s respiratory condition
before managing anxiety.
B. Auscultating breath sounds can provide valuable information regarding the client’s respiratory status. However, in an emergency situation, immediate interventions to stabilize the client should take precedence over assessments, especially since the vital signs indicate significant distress.
C. Elevating the head of the bed can help improve respiratory effort by allowing better lung expansion and reducing the work of breathing. Given the client’s low oxygen saturation and signs of respiratory distress, this intervention can provide immediate relief and improve oxygenation.
D. While this may be necessary if the client's condition worsens or does not improve, it is not the first action to take. Preparing for mechanical ventilation is a more advanced intervention and should only occur after initial stabilization efforts have been made.
Correct Answer is B
Explanation
This timing allows for 30 minutes after administration. Since insulin lispro starts working in about 15 minutes, having breakfast at this time ensures that the client’s blood sugar is managed effectively without risking hypoglycemia.
