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.

Correct Answer is A

Explanation

A. The loss of a pulse and the cool, dusky appearance of the foot indicate potential complications such as thrombus formation or arterial occlusion, which require prompt medical evaluation and intervention. Notifying the physician ensures that appropriate diagnostic and therapeutic measures can be taken quickly.
B. While keeping the client warm is important, simply covering the limb does not address the underlying issue of compromised circulation. This action could potentially delay necessary interventions that address the lack of blood flow.
C. Although repositioning the limb might help with circulation, it is not sufficient given the critical nature of the symptoms. It is essential to first inform the physician to get guidance on further evaluation or interventions. Repositioning could also delay timely intervention needed to prevent tissue damage.
D. Elevating the limb might worsen blood flow in a case of compromised circulation. In cases of suspected arterial occlusion, keeping the limb at heart level or below may be more appropriate to promote blood flow. Elevating it could delay necessary treatment.

A. limit intake to non-caloric containing liquids until the glucose is within normal limits. B. monitor blood glucose levels every 4 hours and go to the clinic if it continues to rise. C. decrease intake of carbohydrates until blood glucose level is less than 200 mg/dL D. hold the morning prescribed dose of insulin.

Correct Answer is B

Explanation

A. While staying hydrated is essential, especially during illness, limiting intake to non-caloric liquids could lead to inadequate caloric intake and worsen the client’s condition. Instead, the client should maintain a balanced intake of fluids and carbohydrates as tolerated.
B. This is a reasonable approach. Monitoring blood glucose levels regularly allows the client to assess how their body is responding to the illness and any adjustments in insulin. If the levels continue to rise, it is important for the client to seek medical attention to prevent complications like diabetic ketoacidosis (DKA).
C. While it is important to manage carbohydrate intake, completely decreasing carbohydrate intake can lead to inadequate caloric consumption, which is especially risky during an illness. The body needs energy, and people with diabetes must balance carbohydrate intake with insulin administration to avoid complications.
D. Holding insulin can lead to dangerously high blood glucose levels. Clients with Type 1 diabetes require insulin regardless of illness, and it’s crucial to adjust the insulin regimen based on current blood glucose levels and carbohydrate intake.
