A nurse is reviewing the medical records of a client who has heart failure. The nurse should identify which of the following laboratory results as an indication that the client has fluid volume excess.
Urine specific gravity 1.015
Hematocrit 42%
Urine pH 6.5
BUN 5 mg/dL
The Correct Answer is D
A. A urine specific gravity of 1.015 is within the normal range (1.005–1.030). While fluid volume excess may lead to a lower specific gravity due to urine dilution, this value does not indicate fluid overload and is considered normal.
B. A hematocrit level of 42% is within the normal range for adults (men: 38–50%, women: 35–45%). Hematocrit levels tend to decrease in fluid volume excess due to hemodilution, but this value does not suggest fluid overload.
C. A urine pH of 6.5 is within the normal range (4.5–8.0). Urine pH reflects the acid-base balance rather than fluid status and is not a reliable indicator of fluid volume excess.
D. A BUN level of 5 mg/dL is below the normal range (10–20 mg/dL). In fluid volume excess, the dilution of blood plasma can lead to decreased BUN levels. This low BUN value, in conjunction with clinical symptoms, supports the diagnosis of fluid volume excess.

Correct Answer is B
Explanation
A: Incorrect. Leaning on the crutches for support while standing still is not the correct way to use crutches. It can lead to discomfort and instability.
B: Correct. The client should advance the unaffected leg first while climbing stairs when using crutches. This technique ensures better stability and safety during stair ascent.
C: Incorrect. Standing 5 cm (2 in) from the front of a chair before sitting is not directly related to the use of crutches.
D: Incorrect. Bearing weight on the axilla while standing in the tripod position is not the correct way to use crutches. The tripod position is used for resting, not weight bearing.
Correct Answer is C
Explanation
A. Remove dentures:
- Removing dentures is a step often performed during post-mortem care but may not necessarily need to be completed before family viewing, especially if the dentures are normally worn by the deceased.
B. Apply a shroud around the body with a visible identification tag:
- Applying a shroud with a visible identification tag is an important step for dignified covering and identification but might be more appropriate after the family has viewed the body.
C. Clean soiled areas of the body:
- This is the most appropriate action to ensure the body appears as dignified and comfortable as possible for family viewing. It involves cleaning any visible soiled areas to provide a respectful presentation to the family.
D. Place the client's head in a dependent position:
- Placing the client's head in a dependent position is not typically necessary or recommended in this context. The goal is to ensure the body appears as natural and dignified as possible.
