1. Question 1
   A lab note states: "After 2 minutes of hyperventilation, a student’s end-tidal CO2 decreased and their blood pH increased. Therefore, hyperventilation can cause respiratory alkalosis." Which statement is the reasoning?

   Hyperventilation can cause respiratory alkalosis.After 2 minutes of hyperventilation, a student’s end-tidal CO2 decreased and their blood pH increased.Blood pH is regulated only by the kidneys over several days.Lower CO2 shifts the carbonic acid–bicarbonate equilibrium to reduce H+ concentration, raising blood pH.

2. Question 2
   A student writes: "After drinking 500 mL of water, a volunteer’s urine became lighter in color and urine volume increased over the next hour. Therefore, increased water intake decreases ADH release, leading to reduced water reabsorption in the kidney." Which sentence is the reasoning?

   The volunteer consumed 500 mL of water in a single sitting.Therefore, increased water intake decreases ADH release, leading to reduced water reabsorption in the kidney.After drinking 500 mL of water, a volunteer’s urine became lighter in color and urine volume increased over the next hour.ADH normally increases water reabsorption in the collecting ducts, so less ADH results in more water excreted as dilute urine.

3. Question 3
   A student writes: "After a high-carbohydrate meal, a patient’s blood glucose increased. Thirty minutes later, blood insulin was higher and blood glucose began to decrease. Therefore, insulin promotes uptake of glucose by body cells." Which statement is the reasoning?

   Because insulin signals cells (especially skeletal muscle and adipose tissue) to take up glucose, increased insulin can lead to a decrease in blood glucose.Thirty minutes later, blood insulin was higher and blood glucose began to decrease.Insulin promotes uptake of glucose by body cells.After a high-carbohydrate meal, a patient’s blood glucose increased.

4. Question 4
   A student writes: "After giving a patient a dose of furosemide, the patient produced more urine over the next 2 hours and their ankle swelling decreased. Therefore, furosemide reduces edema by increasing renal excretion of sodium and water." Which sentence is the reasoning?

   Furosemide reduces edema by increasing renal excretion of sodium and water.After giving a patient a dose of furosemide, the patient produced more urine over the next 2 hours and their ankle swelling decreased.Edema is swelling caused by fluid accumulation in tissues.When the kidneys excrete more sodium, water follows osmotically into the urine, decreasing plasma volume and reducing fluid movement into interstitial spaces.

5. Question 5
   A student writes: "After a patient receives an intramuscular epinephrine injection, the patient’s heart rate increases within minutes. Therefore, epinephrine increases heart rate by activating beta-1 adrenergic receptors in the heart." Which statement is the reasoning?

   After a patient receives an intramuscular epinephrine injection, the patient’s heart rate increases within minutes.Epinephrine increases heart rate by activating beta-1 adrenergic receptors in the heart.Epinephrine is administered intramuscularly for certain acute allergic reactions.Beta-1 adrenergic receptor activation in cardiac tissue increases the rate of SA node firing, which increases heart rate.
