The nurse is teaching a patient to wash their hands after using the bathroom as an attempt to break the chain of infection.
Between which two links in the chain of infection does this action intervene?

Infectious agent and reservoir.

Mode of transmission and portal of entry.

Susceptible host and infectious agent.

Portal of exit and mode of transmission.

Answer and Explanation

The Correct Answer is D

Choice A rationale

The infectious agent is the pathogen that causes the disease, and the reservoir is where the infectious agent lives and multiplies. Hand washing does not directly intervene between these two links.

Choice B rationale

The mode of transmission is how the infectious agent travels to other people and places, and the portal of entry is the route by which an infectious agent enters a new host. Hand washing does not directly intervene between these two links.

Choice C rationale

The susceptible host is a person who is vulnerable to the disease, and the infectious agent is the pathogen that causes the disease. Hand washing does not directly intervene between these two links.

Choice D rationale

The portal of exit is the route by which an infectious agent escapes or leaves the reservoir, and the mode of transmission is how the infectious agent travels to other people and places. Hand washing directly intervenes between these two links by removing the infectious agent from the hands (portal of exit) and preventing its transmission to other people or surfaces.

Correct Answer is A

Explanation

Choice A rationale

Trimethoprim-sulfamethoxazole is an antibiotic used to treat or prevent bacterial infections. One of the key instructions for patients taking this medication is to increase fluid intake to 3 to

4 liters per 24 hours. This is because the medication can crystallize in the urine, which can lead to kidney stones or damage if the patient is not adequately hydrated.

Choice B rationale

Spending time in the sun does not improve the metabolism of trimethoprim-sulfamethoxazole. In fact, the medication can make the skin more sensitive to the sun, increasing the risk of sunburn.

Choice C rationale

Taking Kaopectate daily to prevent diarrhea is not a standard instruction for patients taking trimethoprim-sulfamethoxazole. Diarrhea can be a side effect of the medication, but it should be managed under the guidance of a healthcare provider.

Choice D rationale

There is no specific instruction to take trimethoprim-sulfamethoxazole every morning at the same time as hydrochlorothiazide. The timing of medication administration should be determined by the healthcare provider based on the patient’s overall treatment plan.

A. Febrile and shallow respirations B. Increased rate and depth of respiration C. Weakness and weight gain D. Extremity tremors followed by seizure activity

Correct Answer is B

Explanation

Choice A rationale

Febrile and shallow respirations are not typically associated with uncontrolled diabetes mellitus and ketoacidosis. These symptoms could be indicative of a different medical condition.

Choice B rationale

An increased rate and depth of respiration, also known as Kussmaul breathing, is a common clinical manifestation in patients with uncontrolled diabetes mellitus and ketoacidosis.

Choice C rationale

Weakness and weight gain are not typically associated with uncontrolled diabetes mellitus and ketoacidosis. These symptoms could be indicative of a different medical condition.

Choice D rationale

Extremity tremors followed by seizure activity are not typically associated with uncontrolled diabetes mellitus and ketoacidosis. These symptoms could be indicative of a different medical condition.
