A nurse is educating a client that is newly prescribed with prazosin for hypertension.Which of the following statements should the nurse include in her education about this medication?
This medication should be started at the lowest dose and taken at night.
Start this medication at the highest dose possible.
No need to monitor your blood pressure with the first dose of this medication.
This medication will control your hypertension within a week.
The Correct Answer is A
Choice A rationale
Prazosin, an alpha-blocker, is often started at the lowest dose and taken at night to minimize the risk of orthostatic hypotension, a sudden drop in blood pressure upon standing.
Choice B rationale
Starting prazosin at the highest dose is not recommended due to the risk of severe orthostatic hypotension, which can lead to dizziness and fainting.
Choice C rationale
It is important to monitor blood pressure with the first dose of prazosin to assess the patient's response and avoid significant drops in blood pressure.
Choice D rationale
Prazosin may take several weeks to achieve full therapeutic effect. It does not control hypertension within a week.

Correct Answer is B
Explanation
Choice A rationale
Benztropine is an anticholinergic agent used to treat Parkinsonism and extrapyramidal symptoms, not suitable for reversing heparin effects.
Choice B rationale
Protamine sulfate is the specific antidote for heparin overdose. It works by neutralizing the anticoagulant effects of heparin.
Choice C rationale
Vitamin K is an antidote for warfarin overdose, promoting the synthesis of clotting factors, but ineffective against heparin.
Choice D rationale
Digibind is an antidote for digoxin toxicity, not appropriate for counteracting heparin.
Correct Answer is A
Explanation
Choice A rationale
Losartan is an angiotensin II receptor blocker (ARB) that helps lower blood pressure by relaxing blood vessels. It is often prescribed for clients who cannot tolerate angiotensin-converting enzyme (ACE) inhibitors like Captopril or Lisinopril due to side effects such as a persistent cough.
Choice B rationale
Digoxin is a medication primarily used to treat heart failure and atrial fibrillation. It is not typically prescribed for the management of hypertension as it does not directly lower blood pressure.
Choice C rationale
Captopril is an ACE inhibitor that can cause a persistent cough in some patients. Since the client has experienced this side effect, it is unlikely that Captopril would be prescribed again.
Choice D rationale
Lisinopril is another ACE inhibitor, similar to Captopril. Given the client's history of a cough caused by ACE inhibitors, Lisinopril is also not a suitable option.
