A nurse is caring for a client who has a new prescription for oxygen at 7 L/min via a simple face mask. Which of the following actions should the nurse take to ensure client safety?

The correct answer is choice B. Removing the client's dentures.

Choice A rationale:

Gathering the client's personal belongings is an appropriate action in the postmortem care process. This step allows the family to receive their loved one's belongings, contributing to a compassionate and respectful care process.

Choice B rationale:

Removing the client's dentures requires intervention by the nurse. In postmortem care, dentures should be left in place to maintain the natural appearance of the deceased's face and to ensure that the mouth and lips maintain their proper form.

Choice C rationale:

Placing absorbent pads under the client's buttocks is a common practice to manage any potential leakage of bodily fluids after death. This action helps maintain the cleanliness and dignity of the deceased individual.

Choice D rationale:

Closing the client's eyes is an appropriate action during postmortem care. It provides a peaceful appearance and shows respect for the deceased person.

The correct answer is choice C. Headache.

Choice A rationale:

Fluid overload is not a potential adverse effect of a lumbar puncture. A lumbar puncture involves the removal of cerebrospinal fluid (CSF) from the spinal canal, which wouldn't lead to fluid overload. This choice is not relevant to the procedure.

Choice B rationale:

Diarrhea is not a common adverse effect of a lumbar puncture. The procedure involves accessing the spinal canal and collecting CSF, which is not directly connected to the gastrointestinal system. Diarrhea is unrelated to the procedure.

Choice C rationale:

Headache is a potential adverse effect of a lumbar puncture. This is caused by the leakage of cerebrospinal fluid (CSF) through the puncture site, leading to a decrease in CSF pressure. This drop in pressure can cause a headache, particularly when the client sits or stands up. The headache is often described as severe and may be accompanied by neck pain and sensitivity to light. It usually resolves within a few days but can be managed with pain relief medications and plenty of fluids.

Choice D rationale:

Difficulty voiding is not a common adverse effect of a lumbar puncture. The procedure involves the lower back and spinal canal, and it doesn't directly affect the urinary system. This choice is unrelated to the procedure and its potential complications.
