A nurse is reinforcing teaching with the partner of a client who is immobile. Which of the following instructions should the nurse give the partner about turning the client in bed?

The correct answer is choice B: A thready pulse.

Choice A rationale:

BUN (blood urea nitrogen) level of 18 mg/dL falls within the normal range, which is typically around 7-20 mg/dL. An elevated BUN might indicate dehydration or kidney dysfunction, but a value of 18 mg/dL does not necessarily suggest fluid volume deficit.

Choice B rationale:

A thready pulse is a weak and easily compressible pulse that indicates poor circulation and reduced fluid volume in the circulatory system. Vomiting and diarrhea lead to fluid loss, which can result in fluid volume deficit. Thus, a thready pulse is a significant finding in this context.

Choice C rationale:

Hemoglobin level of 15 g/dL is within the normal range for hemoglobin (usually around 12-16 g/dL for women and 14-18 g/dL for men). While vomiting and diarrhea can lead to mild dehydration, a hemoglobin level of 15 g/dL alone does not strongly suggest fluid volume deficit.

Choice D rationale:

Prominent neck veins are typically associated with increased central venous pressure, which can indicate fluid volume overload rather than fluid volume deficit. In the context of vomiting and diarrhea, neck veins are unlikely to become prominent due to volume depletion.

The correct answer is choice C: "I should remove constrictive clothing prior to measuring my blood pressure."

Choice A rationale:

"I will wait 15 minutes after drinking coffee to measure my blood pressure." Caffeine intake can temporarily elevate blood pressure, so waiting 15 minutes after drinking coffee is a good practice. However, this is not the most relevant instruction to ensure accurate blood pressure measurement.

Choice B rationale:

"I will measure my blood pressure while my arm is elevated above my heart." Measuring blood pressure with the arm elevated above the heart can result in artificially low readings. The arm should be supported at heart level for accurate results. Therefore, this statement is incorrect.

Choice C rationale:

"I should remove constrictive clothing prior to measuring my blood pressure." This is the correct choice. Constrictive clothing can impact blood flow and give inaccurate readings. Removing tight clothing ensures the blood pressure cuff can be appropriately placed and that the measurements are reliable.

Choice D rationale:

"I should measure my blood pressure immediately after eating breakfast." Blood pressure can be affected by food intake, so it's recommended to wait at least 30 minutes after eating before measuring blood pressure. This choice is not accurate as immediate post-breakfast measurements may not provide accurate results.
