A nurse is caring for a client who is receiving morphine intravenously. Which of the following findings indicates the client is experiencing morphine toxicity?

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.

Rationale:

A. Keep objects in the client's room in the same place: Maintaining a consistent environment helps clients with vision loss navigate safely and confidently. Sudden changes in object placement can increase the risk of disorientation and injury.

B. Ensure there is high-wattage lighting in the client's room: While good lighting benefits clients with partial vision, high-wattage lighting can cause glare or discomfort. The focus should be on well-distributed, non-glare lighting suited to individual needs rather than universally high intensity.

C. Touch the client gently to announce presence: Gently touching a visually impaired client before speaking helps avoid startling them and fosters trust. It is a respectful way to make presence known when visual cues are unavailable.

D. Approach the client from the side: Approaching from the front is preferable so the client can better perceive the nurse's presence through remaining visual fields or auditory cues. Side approaches may lead to disorientation or surprise.

E. Allow extra time for the client to perform tasks: Clients with vision loss may require additional time to complete self-care or communication tasks. Rushing them can increase stress and compromise safety, so patience supports their independence.
