(c) the ICF becomes hypotonic with respect to the plasma. (d) water moves from the ICF into the ECF.arrow_forward70. A 68-year-old man with chronic respiratory acidosis has an arterial pH of 7.34 and an arterial PCO₂ of 55 mm Hg. Which of the following best explains the compensatory response to the acidosis?

- Hypokalemia can cause life-threatening cardiac arrhythmias. What is the underlying cause of hypokalemia in DKA and HHNKS? Question 9 options: a) Osmotic diuresis b) Prior deficit from poor nutrition c) Shift of potassium back into cell due to fluid rehydration d) Shift of potassium out of the cell due to correction of metabolic acidosisarrow_forward70.

What is the most important buffer inside cells?arrow_forwardRespiratory acidosis can occur when___ A) a person’s breathing is shallow due to obstruction B) a runner has complete completed a very long marathon C) kidneys secrete hydrogen ionsarrow_forward
- What factors control the movement of water between interstitial fluid and intracellular fluid?arrow_forwardOne type of diuretic given to people with high blood pressure, renal disease and congestive heart failure are thiazide-type diuretics. These drugs inhibit sodium ion reabsorption by inhibiting the transport in the ascending limb of the loop of Henle. A) What does it mean to inhibit the transport of sodium ions in the loop of Henle? B) Explain how this inhibition of sodium ions in the loop of Henle could help increase urine production.arrow_forwardWhat is acid-base homeostasis?arrow_forward
