The nurse is evaluating the outcome of the treatment goals for a client with heart failure.
Which of the following would be the best query for the nurse to ask?

Choice A rationale

Phosphodiesterase type 5 inhibitors, such as sildenafil, are the next step in treating erectile dysfunction after lifestyle changes fail. These medications enhance nitric oxide-mediated vasodilation in the penile tissues, improving erectile function. Their efficacy, safety, and widespread availability make them the first-line pharmacological option.

Choice B rationale

Negative-pressure devices, like vacuum erection devices, mechanically increase blood flow to the penis to maintain an erection. While effective for some, they are typically considered after the failure of oral pharmacological agents, as they require significant user compliance and may cause discomfort.

Choice C rationale

Penile injections of vasodilatory agents, such as alprostadil, are effective for managing erectile dysfunction. However, these are invasive and often reserved for cases unresponsive to oral medications or mechanical devices. They are not typically the first choice after lifestyle modification.

Choice D rationale

Penis transplantation is an experimental treatment and not a standard approach to managing erectile dysfunction. Its application is limited to cases of significant penile trauma or congenital abnormalities and is not relevant for individuals without such conditions.

Choice A rationale

Assessing energy levels provides indirect information about cardiac output but lacks specificity regarding fluid overload or pulmonary congestion, which are key indicators of heart failure exacerbation. It is a relevant question but not the best for evaluating treatment outcomes.

Choice B rationale

Asking about pillow use evaluates orthopnea, a common symptom of heart failure due to fluid buildup in the lungs when lying flat. It provides a direct assessment of fluid status and the effectiveness of heart failure management, making it the best question.

Choice C rationale

Exercising regularly is an important lifestyle aspect for heart failure patients but does not directly assess the status of symptoms such as fluid overload or cardiac function. Thus, it is not the most critical outcome measure.

Choice D rationale

Chest pain can indicate ischemia or worsening cardiac function but is not specific to fluid status or pulmonary congestion in heart failure. Therefore, it is a relevant but less optimal question for evaluating treatment goals.
