A nurse is caring for a client with allergic rhinitis.
The client is newly prescribed guaifenesin.
What is the medication class for this medication?

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.

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.
