. A nurse is caring for a client who has a prescription for hydrochlorothiazide for the initial treatment of hypertension. Which of the following should the nurse recognize as the action of this medication?
Hydrochlorothiazide prevents angiotensin II from binding with receptor sites.
Hydrochlorothiazide decreases the reabsorption of sodium and water in the distal renal tubule.
Hydrochlorothiazide blocks stimulation of beta receptors in the sympathetic nervous system.
Hydrochlorothiazide promotes the movement of extravascular fluids into the vascular compartment.
The Correct Answer is B
A. Hydrochlorothiazide does not prevent angiotensin II from binding with receptor sites; this action is typically associated with ACE inhibitors or angiotensin receptor blockers.
B. Hydrochlorothiazide decreases the reabsorption of sodium and water in the distal renal tubule, which leads to increased urine output and decreased blood volume, effectively lowering blood pressure.
C. Hydrochlorothiazide does not block beta receptors; this is the mechanism of action for beta-blockers.
D. Hydrochlorothiazide does not promote the movement of extravascular fluids into the vascular compartment; instead, it reduces blood volume by promoting diuresis.

Correct Answer is ["100"]
Explanation
Infusion rate (mL/hr) = Volume to be infused (mL) / Time (hr)
In this case:
- Volume to be infused = 100 mL
- Time = 1 hour
Plugging the values into the formula:
- Infusion rate = 100 mL / 1 hour = 100 mL/hr
