Answers | NCLEX®-RN® Readiness)
A nurse is planning care for a client who has experienced excessive fluid loss. Which of the
following interventions should the nurse include in the plan of care? A. Administer IV fluids
evenly over 24 hr.
B. Provide the client with a salt substitute.
C. Assess for pitting edema.
D. Encourage the client to rise slowly when standing up.
E. Weigh the client every 8 hr.
A, D, E
A nurse is caring for a client who has a serum sodium level of 155 mEq/L. Which of the
following IV fluid prescriptions should the nurse anticipate administering?
a. Dextrose 5% in 0.9% sodium chloride
b. dextrose 5% in lactated ringer's
c. 3% sodium chloride
d. 0.45% sodium chloride
D. this pt is hypernatremic, so want to give a hypotonic solution The 0.45% sodium chloride is a
hypotonic solution used to provide free water and treat cellular dehydration, which promotes
waste elimination by the kidneys.
A nurse is reviewing the lab report of a client who has fluid volume excess. Which of the

Answers | NCLEX®-RN® Readiness)
a. Hemoglobin 20 g/dL.
b. Hematocrit 34%.
c. BUN 25 mg/dL.
d. Urine specific gravity 1.050.
b. hematocrit 34%
fluid volume excess will cause what in hemoglobin levels?
Hgb reference range = 13.5-17.5 for males & 12-15.5 for females, therefore, the listed value is
above the reference range. Fluid volume excess can cause hemodilution and a decreased Hgb
level.
fluid volume excess will do what to the BUN level? why?
Fluid volume excess can cause a decrease in BUN (normal reference range = 10-20 mg/dL). The
BUN level listed is increased, which is associated with dehydration.
Fluid volume excess will do what to specific gravity of urine? why?
Fluid volume excess can cause a decrease in urine specific gravity (normal reference range =
1.010-1.025). The urine specific gravity listed is increased, which is associated with dehydration.
