1. The nurse uses a diagram to demonstrate how in dehydration the water is drawn into the plasma from
the cells by which process?
a. Distillation
b. Diffusion
c. Filtration
d. Osmosis
ANS: D
The process of osmosis accomplishes the movement of water from the cells into the plasma, causing
dehydration.
2. The nurse assessing a patient with vomiting and diarrhea observes that the urine is scant and
concentrated. Which controlling factor is responsible for compensatory reabsorption of water?
a. Osmoreceptors in the hypothalamus
b. Antidiuretic hormone in the posterior pituitary
c. Baroreceptors in the carotid sinus
d. Insulin from the pancreas
ANS: B
The antidiuretic hormone controls how much water leaves the body by reabsorbing water in the renal
tubules.

they are equally divided.
4. Which term describes the active transport process that moves sodium and potassium into or out of
cells?
a. Filtration

hours. The nurse calculates that this weight loss is equivalent to how many liters (L) of fluid?
a. 1 L
b. 1.5 L
c. 2.0 L
d. 2.5 L
ANS: D
Each kilogram (2.2 pounds) of weight loss is equivalent to 1 liter of fluid. Therefore, 5.5 pounds ÷ 2.2
pounds = 2.5 liters.
6. The nurse is caring for a patient with a potassium level of 2.9 mEq/L. The nurse should carefully
monitor the patient for which potential problem?
a. Excessive urinary output
