A nurse is caring for a client who has been vomiting and has diarrhea. Which of the following findings should the nurse identify as an indication of fluid volume deficit?
BUN 18 mg/dL.
A thready pulse.
Hemoglobin 15 g/dL.
Prominent neck veins.
The Correct Answer is B
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.

Correct Answer is D
Explanation
The correct answer is choiced. "Describe your concerns about sleeping to me.".
Choice A rationale:
While offering frequent checks can provide some reassurance, it does not address the underlying fear the client is experiencing. It is more of a practical solution rather than a therapeutic one.
Choice B rationale:
Agreeing with the client’s fear without offering a solution or support can increase their anxiety. It is important to acknowledge their feelings but also to provide comfort and reassurance.
Choice C rationale:
Offering sleeping medication might help the client fall asleep, but it does not address the root cause of their fear. It is important to understand and address the client’s concerns directly.
Choice D rationale:
Asking the client to describe their concerns is a therapeutic approach that encourages them to express their fears.This allows the nurse to understand the client’s perspective and provide appropriate emotional support.
Correct Answer is A
Explanation
The correct answer is choice A: "Stand with your feet together and your arms at your sides."
Choice A rationale:
This statement is correct. The nurse should instruct the client to stand with their feet together and their arms at their sides for a Romberg test. This position helps to assess the client's ability to maintain balance with minimal sensory input, evaluating their proprioception and vestibular function.
Choice B rationale:
The instruction about the tuning fork is unrelated to the Romberg test. The tuning fork is commonly used to assess hearing and vibratory sensations, not balance.
Choice C rationale:
This statement is unrelated to the Romberg test. Mentioning the lateral side of the foot suggests a neurological examination related to assessing reflexes, such as the Babinski reflex.
Choice D rationale:
This instruction pertains to a different test known as the "finger-to-nose" test, which is used to assess coordination, not balance.
