A 14-year-old male is taking tolterodine (Detrol). What is the action of this drug?

A.

Decreases the urge to void.

B.

Acidifies urine

C.

Prevents urinary retention.

D.

Restores bladder tone and function.

Answer and Explanation

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.

Correct Answer is ["7.5"]

Explanation

Order: 750 mg PO

Available: 0.5 g/5 mL

Convert 0.5 g to mg:

0.5g=500 mg

To calculate the volume:

Volumetoadminister= (Ordered dose /Available concentration)× Volumeperavailabledose

= (750mg /500 mg) × 5ml

= 7.5 ml

Correct Answer is B

Explanation

A. Check for edema of the legs and ankles: Edema is not a common complication of lithotripsy. Monitoring for stone fragments and urinary symptoms is more relevant.

B. Watch for stone debris in the urine in 1 to 4 weeks: Lithotripsy fragments stones, and the patient is expected to pass debris in the urine for several weeks post-procedure.

C. Remain on restricted activity for a week: Patients can usually resume normal activity shortly after lithotripsy unless otherwise instructed.

D. Decrease fluid intake to 1000 mL/day: Increased fluid intake is encouraged to help flush out stone fragments and reduce the risk of recurrence.
