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 B
Explanation
The correct answer is choice B. Remove the cover gown in the client’s room after providing care. This is because Clostridium difficile spores are not effectively killed by alcohol-based hand rubs and can survive on surfaces for a long time. Removing the gown in the client’s room helps to contain any spores that may have settled on the gown, preventing them from being spread to other areas.
Choice A rationale:
Cleaning hands with an alcohol-based hand rub immediately after removing gloves is wrong because C. difficile spores are resistant to alcohol-based hand rubs. The recommended practice is thorough handwashing with soap and water to physically remove the spores from the hands.
Choice C rationale:
Placing the client in a room with negative-pressure airflow is wrong because this measure is used for airborne infections, such as tuberculosis. C. difficile is spread via the fecal-oral route, primarily through contact with contaminated surfaces or hands, not through the air.
Choice D rationale:
Wearing a mask when administering oral medications to the client is wrong because C. difficile is not spread through respiratory droplets. Masks are not necessary unless there is a risk of splash or spray of contaminated material.
Correct Answer is C
Explanation
The correct answer is choice C. Pallor with scaly skin.
Choice A rationale:
"Heart rate 89/min." Heart rate within the range of 60-100 beats per minute is generally considered normal for adults at rest. This value doesn't specifically indicate malnourishment.
Choice B rationale:
"Pink mucous membranes." Pink mucous membranes indicate adequate oxygenation and hydration but don't necessarily reflect nutritional status or malnourishment.
Choice C rationale:
"Pallor with scaly skin." Pallor (pale skin) along with scaly skin can be indicative of malnourishment. Malnourished individuals may not receive adequate n
Choice D rationale:
"Body mass index 23." A body mass index (BMI) of 23 falls within the normal range (18.5-24.9), so it doesn't necessarily indicate malnourishment. However, BMI alone may not fully capture malnourishment, as it doesn't consider other factors like muscle mass and specific nutrient deficiencies.
