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?
Hypotension
Hypovolemia
Cardiogenic shock
Left ventricular failure
The Correct Answer is D
Rationale:
A. Hypotension: Hypotension is typically associated with decreased preload and low PAWP rather than elevated values. An elevated PAWP reflects increased pressure in the left heart, which does not occur with simple hypotension alone.
B. Hypovolemia: Hypovolemia leads to decreased circulating blood volume, reducing preload and PAWP. It is typically marked by low filling pressures, not elevated wedge pressures.
C. Cardiogenic shock: Although cardiogenic shock can be associated with elevated PAWP due to poor cardiac output and fluid backup, it is not as specific a marker as left ventricular failure, which directly affects PAWP.
D. Left ventricular failure: Elevated PAWP reflects increased pressure in the left atrium and pulmonary circulation, which is a hallmark of left-sided heart failure. This elevation occurs because the failing left ventricle cannot efficiently pump blood forward.

Correct Answer is ["200"]
Explanation
Calculation:
Total volume = 100 mL.
- Convert the infusion time from minutes to hours.
Infusion time = 30 min / 60 min/hr
= 0.5 hr.
- Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
= 100 mL / 0.5 hr
= 200 mL/hr.
Correct Answer is D
Explanation
Rationale:
A. "You are feeling anxious now; why don't you give it some time before making a final decision?": This minimizes the client’s current emotional distress and does not address the seriousness of the statement. It may come across as dismissive rather than therapeutic.
B. "You should talk with your family members before making this decision.": Although involving family in major decisions can be helpful, the focus should be on the client's feelings and wishes first.
C. "I will discuss this with your primary health care provider, and we can discuss this more tomorrow.": Deferring the conversation may delay support for someone expressing emotional exhaustion and possible suicidal ideation. Prompt intervention is essential in these situations.
D. "Let me refer you to talk to someone regarding your treatment options.": This response acknowledges the client's emotional state while also offering a supportive and appropriate next step. It opens access to counseling or mental health services and helps the client explore options without judgment.
