Which of the following actions should the nurse plan to take?

Aspirate carefully after inserting the needle into the client's skin.

Expel the air bubble from the prefilled syringe before injection.

Administer the injection in the client's thigh.

Insert the needle completely into the client's tissue.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Aspiration is not recommended for subcutaneous injections because it can increase tissue damage and pain. Enoxaparin should be administered without aspiration.

Choice B rationale

Prefilled syringes of enoxaparin contain an air bubble to ensure the entire dose is administered. Expelling the air bubble before injection is not recommended.

Choice C rationale

Enoxaparin should be administered in the abdomen, at least 2 inches away from the umbilicus, to ensure proper absorption and effectiveness.

Choice D rationale

Enoxaparin should be administered subcutaneously, and the needle should be inserted completely to ensure the medication is delivered into the subcutaneous tissue.

Correct Answer is A

Explanation

Choice A rationale

Metoprolol is a beta-adrenergic blocker that works by decreasing heart rate, myocardial contractility, and cardiac output. It is commonly used to treat hypertension by reducing the workload on the heart and lowering blood pressure.

Choice B rationale

Nitroglycerin is a vasodilator that is used to treat angina by dilating blood vessels and improving blood flow to the heart. It does not have the same mechanism of action as beta-adrenergic blockers.

Choice C rationale

Losartan is an angiotensin II receptor blocker (ARB) that helps relax blood vessels and lower blood pressure. It does not directly decrease heart rate or myocardial contractility like beta-adrenergic blockers.

Choice D rationale

Metformin is an oral hypoglycemic agent used to manage type 2 diabetes by improving insulin sensitivity and reducing glucose production in the liver. It is not used to treat hypertension and does not have the same mechanism of action as beta-adrenergic blockers.

A. Decongestant. B. Mucolytic. C. Antitussive. D. Expectorant.

Correct Answer is D

Explanation

Choice A rationale

Decongestants relieve nasal congestion by reducing swelling of the nasal passages.

Choice B rationale

Mucolytics thin and loosen mucus in the airways, making it easier to cough up.

Choice C rationale

Antitussives suppress coughing.

Choice D rationale

Expectorants, like guaifenesin, help thin and loosen mucus, making it easier to clear from the airways.
