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.

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.

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.

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
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
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.
ADH levels increase and the RAAS is activated.
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.
The decrease in the production of angiotensin II keeps blood vessels more dilated. This lowers
blood pressure.

The decrease in the production of angiotensin II keeps blood vessels more dilated. This lowers
blood pressure.
When is the RASS system activated? In low blood pressure or high blood pressure?
Low blood pressure
In diabetic ketoacidosis, what happens to the anion gap?
Because extra HCO3- is produced, the anion gap decreases.
Because extra HCO3- is produced, the anion gap increases.
Because HCO3- is consumed, the anion gap increases.
Because HCO3- is consumed, the anion gap decreases.
Because HCO3- is consumed, the anion gap increases.
Patients with end stage renal disease are not able to maintain homeostatic levels of potassium,
and the increased level of potassium in their bloodstream can impair cardiac function.
To remove potassium from the blood during dialysis, what should the dialysate do?
It should not contain potassium.
It should have a higher concentration of potassium than that of the bloodstream.
It should have a concentration of potassium that is equal to that of the bloodstream.
It should have a lower concentration of potassium than that of the bloodstream.
It should have a lower concentration of potassium than that of the bloodstream.
Rational: Dialysis relies on diffusion to remove solutes, including waste and potassium, from
the blood. Solutes move from areas of high concentration to areas of low concentration.
When the amount of potassium is lower in the dialysate than in the bloodstream, potassium
