Question 1
As Diane completes her race, what enables her body to maintain homeostasis despite her
increased activity? Choose 3 answers.
Diane's sports drink helped to replace sodium and water lost due to sweating.
Diane's body produces more angiotensin II, allowing her body to constrict blood vessels and
increase her blood pressure.
Diane's kidney reabsorbs more water and sodium in response to ADH and aldosterone.
Extracellular fluid shifts into intracellular fluid, expanding cells and stimulating the thirst
center in the hypothalamus.
Diane's breathing increases to expel more CO2, which decreases pH and brings it back to
homeostatic levels.

,Question 2
Michael's pulmonary edema leads to respiratory acidosis.
How does pH impact Michael's basal metabolic panel? Choose 3 answers.
His CO2 level is increased because his lungs have difficulty removing it from the
bloodstream.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the
bloodstream, K+ moves from cells into the bloodstream.
His sodium level is decreased due to hypervolemia.
His calcium level is reduced because the elevated concentration of H+ makes it easier for
Ca+ to bind to albumin.
His CO2 level is decreased because his lungs have difficulty adding it into the
bloodstream.
CORRECT ANSWER
His CO2 level is increased because his lungs have difficulty removing it from the
bloodstream.
His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the
bloodstream, K+ moves from cells into the bloodstream.
His sodium level is decreased due to hypervolemia.

@THE STUDY VAULT
,What differentiates type I from type II diabetes?
The insulin producing cells of type I diabetics are destroyed, and they do not produce
insulin. In type II diabetics, their cells are less responsive to insulin.
Type I diabetes can be treated, while type II diabetics do not benefit from supplemental
insulin.
The insulin producing cells of type II diabetics are destroyed, and they do not produce
insulin. In type I diabetics, their cells are less responsive to insulin.
Type I diabetes is characterized by high blood glucose levels, while type II diabetics have
normal blood glucose levels.
CORRECT ANSWER
The insulin producing cells of type I diabetics are destroyed, and they do not produce
insulin. In type II diabetics, their cells are less responsive to insulin.
Question 4
A patient with a viral illness and severe vomiting has an elevated CO2 level and a blood pH
of 7.53. She is breathing slowly.
What condition does the patient have?
Metabolic acidosis
Respiratory alkalosis.
Respiratory acidosis
Metabolic alkalosis
CORRECT ANSWER
3
@THE STUDY VAULT
, Metabolic alkalosis
Rational: The patient's pH and CO2 level are both elevating (moving in the same
direction). This indicates metabolic alkalosis. The CO2 level is high because her
respiratory system is attempting to compensate for the high pH by exhaling less and
retaining more CO2
Question 5
What happens in a dehydrated patient?
ADH levels decrease and the RAAS is activated.
ADH levels decrease and the RAAS is inactivated.
ADH levels increase and the RAAS is inactivated.
ADH levels increase and the RAAS is activated.
CORRECT ANSWER
ADH levels increase and the RAAS is activated.
Question 6
ACE (angiotensin converting enzymes) inhibitors are used to treat abnormal blood
pressure. They prevent the conversion of angiotensin I to angiotensin II.
Which explains how ACE inhibitors work?
The decrease in the production of angiotensin II constricts blood vessels. This lowers blood
pressure.
The decrease in the production of angiotensin II keeps blood vessels more dilated. This
raises blood pressure.
