An 84-year-old patient is hospitalized for an infected stasis ulcer on his ankle. The nurse is aware that this patient is at risk for a hospital-acquired infection (HAI) because the:

Stasis ulcers predispose the older adult to pneumonia and urinary infections.

Patient's defenses are already engaged with the initial infection.

Ulcer will make this patient bedfast.

Patient already has a blood-borne infection.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is A

Explanation

Choice A rationale

A 10% solution of chlorine bleach is an effective disinfectant for contaminated areas in the home. Chlorine bleach has broad-spectrum antimicrobial properties, making it suitable for killing various pathogens, including bacteria and viruses.

Choice B rationale

Soaking in a solution of povidone iodine for 30 minutes and rinsing with hot water is not practical for home disinfection. While povidone iodine is effective as a disinfectant, it is typically used for medical purposes and not for cleaning household surfaces.

Choice C rationale

A 12% solution of alcohol is not as effective as a 10% solution of chlorine bleach for disinfecting contaminated areas in the home. Alcohol concentrations above 70% are generally more effective for disinfection purposes.

Choice D rationale

Covering the area with boiling water and letting it air dry is not a reliable method for disinfecting contaminated areas. Boiling water may not effectively kill all pathogens, and this method lacks the broad-spectrum efficacy of chemical disinfectants.

A. Lowers it below his chin to use the next time he enters that patient's room. B. Removes the mask first before removing any other PPE. C. Discards the mask only if it is wet; otherwise, he folds and stores it to reuse the next time. D. Unties the bottom ties first, then the top, and disposes of the mask without touching it.

Correct Answer is D

Explanation

Choice A rationale

Lowering a used mask below the chin to reuse it later is not safe as it can lead to contamination of the mask and facial area, increasing the risk of infection.

Choice B rationale

Removing the mask first before any other personal protective equipment (PPE) can lead to contamination and is not the recommended sequence for doffing PPE.

Choice C rationale

Discarding the mask only if it is wet and storing it for reuse is not safe. Masks should not be reused, as they can harbor infectious agents and increase the risk of contamination.

Choice D rationale

Untying the bottom ties first, then the top, and disposing of the mask without touching it ensures that the person removing the mask avoids contamination. This method adheres to proper doffing procedures and minimizes the risk of infection.
