A nurse is caring for a client with hypertension.The client's current vital signs include a blood pressure of 155/95 mmHg and heart rate of 130 bpm in sinus rhythm.
Which of the following medications should the nurse anticipate giving to the client?
Metoprolol.
Enoxaparin.
Heparin.
Simvastatin.
The Correct Answer is A
Choice A rationale
Metoprolol is a beta-blocker that is commonly used to manage hypertension and control heart rate. It works by blocking beta-adrenergic receptors, which decreases heart rate and blood pressure.
Choice B rationale
Enoxaparin is an anticoagulant used to prevent and treat deep vein thrombosis and pulmonary embolism, not primarily to manage hypertension.
Choice C rationale
Heparin is an anticoagulant used to prevent and treat blood clots, and it is not indicated for the management of hypertension.
Choice D rationale
Simvastatin is a lipid-lowering medication used to manage high cholesterol levels and is not used to manage hypertension.

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
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.
