Patho D236 WGU questions with correct answers
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 CORRECT ANSWER 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. 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.
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. 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 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. CORRECT ANSWER 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. CORRECT ANSWER 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? CORRECT ANSWER 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. CORRECT ANSWER 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.
