NSG 5003 WEEK 5 QUIZ : ADVANCED PATHOPHYSIOLOGY-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 metab ... olic rate c. Kidneys are not mature enough to counter fluid losses d. Inability to communicate adequately when he or she is thirsty - a 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. A patient's blood gases reveal the following findings: pH, 7.3; bicarbonate (HCO3) 27 mEq/L; carbon dioxide (CO2), 58 mm Hg.

Respiratory acidosis 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 In addition to osmosis, what force is involved in the movement of water between the plasma and interstitial fluid spaces? a. Oncotic pressure b. Buffering c. Net filtration d. Hydrostatic pressure - d. Hydrostatic pressure Venous obstruction is a cause of edema because of an increase in which pressure? a. Capillary hydrostatic b. Interstitial hydrostatic c.
