Nsg 5003 Week 5 Quiz Study Ch 3 The Cellular
Environment: Fluids & Electrolytes, Acids & Bases UPDATED
ACTUAL Questions and CORRECT Answers
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
Obesity creates a greater risk for dehydration in people a. Adipose cells contain little water because fat is water repelling.
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 patient's blood gases reveal the following findings: pH, c. Respiratory acidosis
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
Water movement between the intracellular fluid (ICF) a. Osmotic forces
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
In addition to osmosis, what force is involved in the d. Hydrostatic pressure
movement of water between the plasma and interstitial
fluid spaces?
a. Oncotic pressure
b. Buffering
c. Net filtration
d. Hydrostatic pressure
Venous obstruction is a cause of edema because of an a. Capillary hydrostatic
increase in which pressure?
a. Capillary hydrostatic
b. Interstitial hydrostatic
c. Capillary oncotic
d. Interstitial oncotic
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 pressure.
b. Capillary hydrostatic pressure is higher than the
capillary oncotic pressure.
c. Interstitial oncotic pressure is higher than the interstitial
hydrostatic pressure.
d. Capillary oncotic pressure is lower than the interstitial
hydrostatic pressure.
