The nurse explains that the body's normal flora serves as:

Cell rebuilders.

Aids to digestion and blood production.

Prevention to the colonizing of pathogens.

Managers of fluid balance of the body.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Normal flora does not function as cell rebuilders. They primarily exist in a symbiotic relationship with the host without directly participating in cell repair processes.

Choice B rationale

While some normal flora aid in digestion, they are not involved in blood production. Blood production is a function of bone marrow and not influenced by normal flora.

Choice C rationale

Normal flora play a crucial role in preventing the colonization of pathogens by competing for nutrients and space, thereby protecting the body from harmful microorganisms.

Choice D rationale

Normal flora do not manage the fluid balance of the body. Fluid balance is regulated by the kidneys and the body's endocrine system, not by the normal flora.

Correct Answer is B

Explanation

Choice A rationale

Stasis ulcers do not specifically predispose older adults to pneumonia and urinary infections. These infections have different primary risk factors and are not directly related to the presence of stasis ulcers.

Choice B rationale

The patient's defenses are already engaged with the initial infection, which can weaken the immune response and make the body more susceptible to additional infections, such as hospital-acquired infections (HAIs).

Choice C rationale

While being bedfast can increase the risk of pressure sores and related infections, it is not directly caused by the presence of a stasis ulcer. The patient's mobility status and overall health condition are more relevant factors.

Choice D rationale

The patient does not have a blood-borne infection. The presence of a stasis ulcer indicates a local infection, not a systemic blood-borne infection.

A. Caring for patients who have wounds draining body fluids. B. Preventing transmission of respiratory and wound infections. C. Caring for all patients. D. There is a suspicion of or risk of infection.

Correct Answer is C

Explanation

Choice A rationale

While it is true that Standard Precautions apply to patients with draining wounds, these precautions are not limited to such scenarios. They are a broader set of practices.

Choice B rationale

Standard Precautions do help prevent the transmission of respiratory and wound infections, but their application is universal, not limited to these conditions.

Choice C rationale

Standard Precautions are designed to be used when caring for all patients, regardless of their diagnosis or infection status, to prevent the spread of infections.

Choice D rationale

Standard Precautions are used routinely with all patients, not only when there is a suspicion or risk of infection. This universal approach helps ensure a high level of infection control.
