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.
incorrect - Ans--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.
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. - Ans--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.
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. - Ans--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.
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 - Ans--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. - Ans--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 constricts blood vessels.
This raises blood pressure. - Ans--The decrease in the production of
angiotensin II keeps blood vessels more dilated. This lowers blood
pressure.
