1. Question : At the arterial end of capillaries, fluid moves from the intravascular space into the
interstitial space because the:
Student Answer:
Interstitial hydrostatic pressure is higher than the capillary hydrostatic pressure.
Capillary hydrostatic pressure is higher than the capillary oncotic pressure.
Interstitial oncotic pressure is higher than the interstitial hydrostatic pressure.
Capillary oncotic pressure is lower than the interstitial hydrostatic pressure.
Instructor Explanation: At the arterial end of capillaries, fluid moves from the intravascular space
into the interstitial because capillary hydrostatic pressure is higher than the capillary oncotic
pressure.
2. Question : Physiologic pH is maintained at approximately 7.4 because bicarbonate (HCO3)
and carbonic acid (H2CO3) exist in a ratio of:
Student Answer:
20:1
1:20
10:2
10:5
, Instructor Explanation: The relationship between HCO3 and H2CO3 is usually expressed as a
ratio. When the pH is 7.4, this ratio is 20:1 (HCO3:H2CO3). The other options do not accurately
identify physiologic pH by the correct ratio of HCO3 and H2CO3.
3. Question : Which organic compounds facilitate transportation across the cell membrane by
acting as receptors, transport channels for electrolytes, and enzymes to drive active pumps?
Student Answer:
Lipids
Proteases
Proteins
Carbohydrates
Instructor Explanation: Proteins act as (1) recognition and binding units (receptors) for
substances moving in and out of the cell; (2) pores or transport channels for various electrically
charged particles called ions or electrolytes and specific carriers for amino acids and
monosaccharides; and (3) specific enzymes that drive active pumps that promote the
concentration of certain ions, particularly potassium (K+), within the cell while keeping
concentrations of other ions, for example, sodium (Na+), below the concentrations found in the
extracellular environment. The other options do not correctly describe this process.
4. Question : The most common cause of hypermagnesemia is:
Student Answer:
Hepatitis
