A nurse is analyzing the laboratory data on a client who has dehydration. Which finding should the nurse anticipate in a client who has fluid volume deficit?
Decreased serum osmolarity
Decreased hematocrit
Elevated blood urea nitrogen (BUN)
Lower urine specific gravity
The Correct Answer is C
A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.
B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.
C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.
D. Lower urine specific gravity: Dehydration causes increased urine concentration, resulting in higher urine specific gravity, not lower.

Correct Answer is B
Explanation
A. Place the client's valuables in the facility's safe - While securing the client's valuables is important, it is not the priority upon admission.
B. Observe the client's level of mobility - This is the priority as it allows the nurse to assess the client's immediate physical condition and risk of falls or other mobility-related issues.
C. Administer prescribed medications - Medication administration can wait until the client's initial assessment, including mobility, has been completed.
D. Electronically enter the prescriptions from the provider - Entering prescriptions can be done after the initial assessment and immediate needs of the client have been addressed.
