Correct Answer is C

Explanation

A. Decreased GFR (glomerular filtration rate): A low GFR would reduce urine output, not increase it.

B. Over secretion of aldosterone: Aldosterone promotes sodium and water reabsorption, which decreases urine output.

C. Decrease amounts of ADH: Antidiuretic hormone (ADH) helps retain water. A deficiency leads to diuresis, causing polyuria (as seen in diabetes insipidus).

D. Activation of angiotensinogen: This leads to vasoconstriction and aldosterone release, promoting water retention, not polyuria.

A. Avoid gas-producing foods. B. Request that the provider prescribe a stool softener. C. Promote active range-of-motion activities. D. Add fluid and fiber to the diet.

Correct Answer is D

Explanation

A. Avoid gas-producing foods: While this may reduce bloating or discomfort, it does not address constipation directly.

B. Request that the provider prescribe a stool softener: This may help symptomatically, but it's not the first-line intervention.

C. Promote active range-of-motion activities: Exercise helps bowel movement, but fluid and fiber intake is more essential initially.

D. Add fluid and fiber to the diet: Increased fiber adds bulk to the stool, and fluids soften it, both of which promote bowel movement and relieve constipation.
