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 C
Explanation
Choice A reason: Asking for more information about the surgery indicates the client seeks clarification but does not confirm understanding of informed consent. Informed consent requires comprehension of the procedure, risks, benefits, and alternatives, with agreement to proceed. This statement reflects curiosity, not confirmation of understanding, making it insufficient to demonstrate informed consent.
Choice B reason: Planning to ask the doctor about the surgery in the operating room suggests the client has not yet received or understood the necessary information. Informed consent must be obtained before entering the operating room, with full comprehension of risks and benefits. This statement indicates a lack of prior understanding, making it incorrect.
Choice C reason: Stating understanding of the risks, benefits, and agreement to the procedure demonstrates informed consent. This reflects that the client has been educated about the knee arthroplasty, including potential complications like infection or blood clots, and alternatives, and voluntarily agrees to proceed. This meets legal and ethical standards, indicating full comprehension and consent.
Choice D reason: Having family sign the consent form is inappropriate unless the client lacks decision-making capacity, which is not indicated. Informed consent requires the competent client’s understanding and agreement. This statement suggests reliance on others, not personal comprehension of the procedure’s risks and benefits, making it an incorrect indicator of understanding.
Correct Answer is ["B","C"]
Explanation
Choice A reason: Telling the daughter not to worry dismisses her emotional concerns and does not facilitate open communication. Addressing fears about a loved one’s death requires empathy and discussion to process grief and understand hospice care, which focuses on comfort. This response is inappropriate, as it avoids addressing the daughter’s needs.
Choice B reason: Acknowledging the daughter’s concerns about her mother’s death and inviting discussion is therapeutic. It validates her emotions, encouraging open dialogue about grief, hospice care, and end-of-life expectations. This approach supports psychological coping, aligns with palliative care principles, and helps the daughter prepare for her mother’s transition, making it appropriate.
Choice C reason: Discussing the mother’s cancer and its implications helps the daughter understand the disease progression and hospice care’s role in symptom management. This fosters informed communication, addressing fears and clarifying expectations. It supports emotional preparation for end-of-life discussions, making this response appropriate for facilitating understanding and coping.
Choice D reason: Encouraging the daughter to avoid thinking about dying dismisses the reality of the situation and hinders emotional processing. Hospice care involves preparing for end-of-life, and open discussions about death are therapeutic. This response is inappropriate, as it discourages necessary conversations about the mother’s condition and prognosis.
