1. Infants are most susceptible to significant losses in total body water because
of an infant's:
a. High body surface-to-body size ratio
b. Slow metabolic rate
c. Kidneys are not mature enough to counter fluid losses
d. Inability to communicate adequately when he or she is thirsty:
2. Obesity creates a greater risk for dehydration in people because:
a. Adipose cells contain little water because fat is water repelling.
b. The metabolic rate of obese adults is slower than the rate of lean adults.
c. The rate of urine output of obese adults is higher than the rate of output of
lean adults.
d. The thirst receptors of the hypothalamus do not function effectively.: a. Adipose
cells contain little water because fat is water repelling.
3. A patient's blood gases reveal the following findings: pH, 7.3; bicarbonate
(HCO3) 27 mEq/L; carbon dioxide (CO2), 58 mm Hg. What is the interpretation
of these gases?
a. Respiratory alkalosis
b. Metabolic acidosis
c. Respiratory acidosis
d. Metabolic alkalosis: c. Respiratory acidosis
4. Water movement between the intracellular fluid (ICF) compartment and the
extracellular fluid (ECF) compartment is primarily a function of:
a. Osmotic forces
b. Plasma oncotic pressure
c. Antidiuretic hormone
d. Hydrostatic forces: a. Osmotic forces

between the plasma and interstitial fluid spaces?
a. Oncotic pressure
b. Buffering
c. Net filtration
d. Hydrostatic pressure: d. Hydrostatic pressure
6. Venous obstruction is a cause of edema because of an increase in which
pressure?
a. Capillary hydrostatic
b. Interstitial hydrostatic
c. Capillary oncotic
d. Interstitial oncotic: a. Capillary hydrostatic
7. At the arterial end of capillaries, fluid moves from the intravascular space into
the interstitial space because the:
a. Interstitial hydrostatic pressure is higher than the capillary hydrostatic pres-
sure.
b. Capillary hydrostatic pressure is higher than the capillary oncotic pressure.
c. Interstitial oncotic pressure is higher than the interstitial hydrostatic pres-
sure.
d. Capillary oncotic pressure is lower than the interstitial hydrostatic pressure.:
8. Low plasma albumin causes edema as a result of a reduction in which pres-
sure?
a. Capillary hydrostatic
b. Interstitial hydrostatic
c. Plasma oncotic
d. Interstitial oncotic: c. Plasma oncotic
