A nurse is caring for a client that is newly diagnosed with hypertension.Which of the following medications is a beta-adrenergic blocker that has a mechanism of action to decrease heart rate, myocardial contractility, and cardiac output, and is also used to treat hypertension?

The correct answer is Choice B. Choice A rationale: Ondansetron (Zofran) is an antiemetic used to prevent nausea and vomiting. The client denies nausea and vomiting, so this medication is not necessary at this time.

Choice B rationale: Acetaminophen (Tylenol) is appropriate for managing mild pain, which the client reports as 2 out of 10 on the pain scale. This medication effectively alleviates mild pain without significant side effects, making it suitable for the client’s current condition.

Choice C rationale: Hydrocodone/Acetaminophen (Norco) is a combination of an opioid and acetaminophen used for moderate to severe pain. Since the client reports only mild pain (2 out of 10), this stronger medication is not warranted and could cause unnecessary side effects.

Choice D rationale: Melatonin is used to help with sleep. The client does not report any issues with sleep, so administering this medication is not relevant to the current situation.

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.
