A nurse is caring for a client with hypertension that is prescribed metoprolol due at 0900.
The nurse took the client's blood pressure at 0855, and it was noted to be 80/60. The client also notes that he feels dizzy and weak.
What is the next intervention for the nurse?

Administer metoprolol as scheduled.

Withhold the medication and notify the provider.

Administer an additional dose of metoprolol.

Administer lisinopril instead of the prescribed dose of metoprolol.

Answer and Explanation

The Correct Answer is B

Choice B rationale

Withholding the medication and notifying the provider is the appropriate intervention when a client's blood pressure is significantly low, such as 80/60 mmHg. Administering metoprolol, a beta-blocker, in this scenario could further lower the blood pressure, causing more harm. The provider needs to be informed to reassess the treatment plan.

Correct Answer is A

Explanation

Choice A rationale

Propylthiouracil (PTU) is used to treat hyperthyroidism. It works by inhibiting the production of thyroid hormones, thereby reducing symptoms of hyperthyroidism such as rapid heart rate, sweating, and nervousness.

Choice B rationale

Propylthiouracil (PTU) is not used to treat hyperglycemia. Medications for hyperglycemia include insulin and oral hypoglycemic agents.

Choice C rationale

Propylthiouracil (PTU) is not indicated for hypoglycemia. Treatment for hypoglycemia typically includes glucose administration or glucagon.

Choice D rationale

Propylthiouracil (PTU) is not used to treat hypothyroidism. Hypothyroidism is treated with thyroid hormone replacement therapy, such as levothyroxine.

A. Excretion. B. Phlebitis. C. Distribution. D. Absorption.

Correct Answer is B

Explanation

Choice A rationale

Excretion is a phase of pharmacokinetics where the drug or its metabolites are eliminated from the body, primarily via the kidneys.

Choice B rationale

Phlebitis is inflammation of a vein and is not a phase of pharmacokinetics. It is a medical condition rather than a pharmacokinetic process.

Choice C rationale

Distribution is a phase of pharmacokinetics where the drug is dispersed throughout the body’s tissues and fluids after absorption.

Choice D rationale

Absorption is a phase of pharmacokinetics where the drug is absorbed into the bloodstream from the site of administration.
