The nurse is caring for a client diagnosed with a systemic staphylococci infection from the client’s own flora. The nurse correctly notes that this is an example of a(n):

Exogenous Infection.

Endogenous Infection.

Community Acquired Infection.

Nosocomial Infection.

Answer and Explanation

The Correct Answer is B

Choice A rationale
An exogenous infection occurs when a pathogen enters a patient’s body from their environment. For example, a healthcare worker can spread the infection due to poor adherence to infection control practices. This is not the case here as the infection is from the client’s own flora.
Choice B rationale
An endogenous infection is caused by the body’s normal flora. These microorganisms may act as opportunistic pathogens when the host is susceptible. In this case, the client’s systemic staphylococci infection originated from their own flora, making it an endogenous infection.
Choice C rationale
A community-acquired infection is one that was present or incubating prior to the patient being admitted to the hospital. Since the infection in this case originated from the client’s own flora and not from the community, this choice is incorrect.
Choice D rationale
A nosocomial infection, also known as a hospital-acquired infection, is an infection that is acquired in a hospital or other healthcare facility. Since the client’s infection originated from their own flora and not from the hospital environment, this choice is incorrect.

Correct Answer is D

Explanation

Choice A rationale
Respiratory acidosis is characterized by a pH less than 7.35 and a PaCO2 greater than 454. In this case, the pH is 7.43, which is within the normal range, and the PaCO2 is 46, which is slightly above the normal range. Therefore, this does not indicate respiratory acidosis.
Choice B rationale
Respiratory alkalosis is characterized by a pH greater than 7.45 and a PaCO2 less than 354. In this case, the pH is 7.43, which is within the normal range, and the PaCO2 is 46, which is slightly above the normal range. Therefore, this does not indicate respiratory alkalosis.
Choice C rationale
Metabolic acidosis is characterized by a pH less than 7.35 and a HCO3 less than 224. In this case, the pH is 7.43, which is within the normal range, and the HCO3 is 35, which is above the normal range. Therefore, this does not indicate metabolic acidosis.
Choice D rationale
Metabolic alkalosis is characterized by a pH greater than 7.45 and a HCO3 greater than 264. In this case, the pH is 7.43, which is within the normal range, and the HCO3 is 35, which is above the normal range. Therefore, this indicates metabolic alkalosis.

A. Clients should designate a single area in the home for smoking while using oxygen. B. To prevent falls, throw rugs should have bright patterns. C. Carbon monoxide detectors should be strategically installed throughout the home. D. If any poison is ingested, ipecac should be administered to induce vomiting.

Correct Answer is C

Explanation

Choice A rationale
Designating a single area in the home for smoking while using oxygen is not a safe practice. Oxygen supports combustion and can cause materials to ignite more easily and burn faster, increasing the risk of fires and severe burns.
Choice B rationale
While bright patterns on throw rugs may make them more visible, they can still pose a tripping hazard, especially for older adults or individuals with mobility issues.
Choice C rationale
Installing carbon monoxide detectors throughout the home is a key safety measure. Carbon monoxide is a colorless, odorless gas that can cause sudden illness and death if inhaled.
Choice D rationale
Administering ipecac to induce vomiting after ingesting poison is not recommended. It can cause harm and is not effective for all types of poisonings.
