Correct Answer is D

Explanation

A. Equal to the excretion of urea: Urea excretion contributes to osmolality but does not define it.

B. In a ratio of 10:1 with the serum: This is not a recognized ratio for urine and serum osmolality.

C. Approximately half of the serum: In a healthy kidney, urine osmolality may vary but typically equals serum osmolality in a state of balance.

D. Equal to the osmolality of the serum: Under normal conditions, the kidney regulates urine osmolality to maintain a balance with serum osmolality, reflecting adequate kidney function.

A. “I will limit my fluid intake.” B. “I will chew gum to relieve my dry mouth.” C. “I will eat fresh fruits.” D. “I will not drive if I develop blurred vision.”

Correct Answer is A

Explanation

A. "I will limit my fluid intake.": Anticholinergic agents can lead to urinary retention and dehydration, so limiting fluid intake can exacerbate side effects. Patients should be encouraged to maintain adequate hydration.

B. "I will chew gum to relieve my dry mouth.": Dry mouth is a common side effect of anticholinergics, and chewing gum can help alleviate it.

C. "I will eat fresh fruits.": Fresh fruits can help prevent constipation, another common side effect of anticholinergic medications.

D. "I will not drive if I develop blurred vision.": Blurred vision is a side effect of anticholinergics, and patients should avoid driving or operating machinery if it occurs.
