A nurse is caring for a client who has a new prescription for warfarin.Which of the following is a therapeutic use of this medication?
This medication prevents venous thrombosis.
This medication prevents angina pectoris.
This medication is to treat bradycardia.
This medication is to treat hypertension.
The Correct Answer is A
Choice A rationale
Warfarin is an anticoagulant that is used to prevent venous thrombosis and thromboembolic events by inhibiting the synthesis of vitamin K-dependent clotting factors.
Choice B rationale
Warfarin is not used to prevent angina pectoris, which is typically managed with nitrates, beta-blockers, or calcium channel blockers.
Choice C rationale
Warfarin is not used to treat bradycardia, which is usually managed with medications like atropine or pacemaker implantation.
Choice D rationale
Warfarin is not used to treat hypertension. Antihypertensive medications such as ACE inhibitors, beta-blockers, or diuretics are used for this purpose.

Correct Answer is A
Explanation
Choice A rationale
Rotating injection sites helps prevent lipohypertrophy, which is the thickening of subcutaneous tissue due to repeated insulin injections at the same site.
Choice B rationale
Performing injections at the same location every time increases the risk of lipohypertrophy, leading to poor insulin absorption and erratic glucose control.
Choice C rationale
Administering an additional dose of insulin as needed does not address the issue of lipohypertrophy and can lead to hypoglycemia if not carefully monitored.
Choice D rationale
Insulin is a peptide hormone that must be injected. Taking it orally is ineffective as it would be broken down in the digestive system.
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.
