A 14-year-old male is taking tolterodine (Detrol). What is the action of this drug?
Decreases the urge to void.
Acidifies urine
Prevents urinary retention.
Restores bladder tone and function.
The Correct Answer is A
A. Decreases the urge to void: Tolterodine (Detrol) is an anticholinergic medication used to treat overactive bladder by reducing bladder contractions, thereby decreasing the urge to void.
B. Acidifies urine: Tolterodine does not alter urine pH. Medications like ascorbic acid are used to acidify urine.
C. Prevents urinary retention: Tolterodine can actually cause or exacerbate urinary retention as a side effect.
D. Restores bladder tone and function: Tolterodine does not restore bladder tone but works by relaxing the bladder muscles to reduce urinary urgency and frequency.

Explanation
A. Hyperkalemia: Hyperkalemia is the most life-threatening effect of renal failure because elevated potassium levels can cause dangerous cardiac arrhythmias or cardiac arrest.
B. Hypokalemia: Hypokalemia is not commonly associated with renal failure and is less immediately life-threatening than hyperkalemia.
C. Hypernatremia: While fluid imbalances can lead to hypernatremia, it is less critical than hyperkalemia in renal failure.
D. Hyponatremia: Although hyponatremia can occur in renal failure, its effects are typically less acutely life-threatening than hyperkalemia.
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.
