A nurse is assessing a client’s pulmonary artery wedge pressure (PAWP). The nurse should recognize that an elevated PAWP indicates which of the following complications?
Cardiogenic shock
Left ventricular failure
Hypotension
Hypovolemia
The Correct Answer is B
Choice A reason: Cardiogenic shock involves reduced cardiac output, typically with low PAWP due to decreased preload from poor heart function. Elevated PAWP reflects left atrial pressure buildup, not characteristic of cardiogenic shock alone, which is distinct from heart failure, requiring specific hemodynamic management.
Choice B reason: Elevated PAWP indicates left ventricular failure, where the heart cannot pump blood effectively, causing pulmonary congestion. This increases left atrial pressure, leading to pulmonary edema, a hallmark of heart failure. Diuretics and inotropes are needed to reduce fluid overload and improve cardiac function.
Choice C reason: Hypotension is a symptom, not a direct complication of elevated PAWP. It may occur in heart failure due to reduced cardiac output, but elevated PAWP specifically signals left heart dysfunction, not hypotension itself, which is a systemic response rather than a primary cardiac issue.
Choice D reason: Hypovolemia reduces blood volume, lowering PAWP due to decreased preload. Elevated PAWP suggests fluid overload or left ventricular dysfunction, not hypovolemia, which presents with low central venous pressure and dehydration signs, requiring fluid resuscitation rather than management of heart failure.

Correct Answer is B
Explanation
Choice A reason: Financial power of attorney manages monetary decisions, not health care, unless specified as a health care surrogate. Advance directives guide health decisions, but this role is distinct, making this statement incorrect under the Patient Self-Determination Act’s provisions.
Choice B reason: The Patient Self-Determination Act ensures clients’ rights to refuse treatment, even against provider recommendations, promoting autonomy through advance directives. This legal protection applies in Medicare/Medicaid facilities, making it the correct principle for end-of-life decision-making in this context.
Choice C reason: Advance directives can be changed by a competent client, even if notarized, as the Act supports ongoing autonomy. Stating they cannot be altered is incorrect, as flexibility is a core feature, making this an inaccurate representation of the law.
Choice D reason: The eldest adult child cannot change advance directives unless designated as a surrogate. The Act prioritizes the client’s documented wishes or appointed decision-maker, not family hierarchy, making this statement incorrect and misaligned with legal requirements.
Correct Answer is C
Explanation
Choice A reason: Administering atomoxetine, used for ADHD, is inappropriate for panic attacks, which require short-acting anxiolytics like benzodiazepines if medicated. This medication does not address acute anxiety and may worsen symptoms, making it incorrect and potentially harmful.
Choice B reason: Encouraging television watching may distract but does not address the acute distress of a panic attack. It lacks the calming, supportive presence needed to reduce anxiety, making it less effective and inappropriate compared to direct emotional support.
Choice C reason: Sitting with the client provides a calming presence, reducing fear and enhancing security during a panic attack. This therapeutic intervention supports emotional regulation and aligns with evidence-based anxiety management, making it the correct and most effective action.
Choice D reason: Instructing strenuous exercise during a panic attack can exacerbate symptoms like tachycardia and breathlessness, worsening anxiety. Calming techniques like deep breathing are preferred, so this action is counterproductive and potentially harmful, making it incorrect.
