A nurse is reviewing the medical record of a client who is prescribed tetracycline.
The nurse would be alert for an increased risk of toxicity if the client is taking which of the following?

Digoxin (Lanoxin).

Phenytoin (Dilantin).

Vancomycin (Vancocin).

Carbamazepine (Tegretol). .

Answer and Explanation

The Correct Answer is A

Choice A rationale: Tetracycline can increase the levels of digoxin (Lanoxin) in the blood, leading to an increased risk of digoxin toxicity. This interaction occurs because tetracycline can interfere with the metabolism and excretion of digoxin, causing higher concentrations of the drug in the bloodstream1. Symptoms of digoxin toxicity include nausea, vomiting, dizziness, and cardiac arrhythmias. Therefore, patients taking both medications should be closely monitored for signs of toxicity and may require dosage adjustments.

Choice B rationale: Phenytoin (Dilantin) does not have a significant interaction with tetracycline that increases the risk of toxicity. While both medications can be used together, they do not significantly affect each other's metabolism or excretion1.

Choice C rationale: Vancomycin (Vancocin) does not have a significant interaction with tetracycline that increases the risk of toxicity. Both medications can be used together without causing significant changes in their metabolism or excretion1.

Choice D rationale: Carbamazepine (Tegretol) does not have a significant interaction with tetracycline that increases the risk of toxicity. While both medications can be used together, they do not significantly affect each other's metabolism or excretion

Correct Answer is A

Explanation

Choice A rationale:

Emetics are medications that induce vomiting and are used in cases of drug overdose, ingestion of toxic substances, or other situations where rapid removal of the ingested substance is necessary. However, it is crucial that the client's mental status is intact and they can cooperate and understand the need to induce vomiting. If a client is unconscious or unable to protect their airway, inducing vomiting can lead to aspiration and further complications.

Choice B rationale:

Clients with existing severe hypertension should not be administered emetics, as the act of inducing vomiting can lead to a sudden increase in blood pressure, potentially causing adverse cardiovascular events.

Choice C rationale:

Clients with a medical history of convulsions (seizures) should not be given emetics. Inducing vomiting may lead to a convulsive episode, which can be harmful and increase the risk of aspiration.

Choice D rationale:

Clients with an existing condition of hemorrhagic diathesis (a tendency to bleed excessively) should not be administered emetics. Inducing vomiting can cause mucosal damage and bleeding in the gastrointestinal tract, further exacerbating the client's condition.

A. Leads to a complete cure of cancer. B. Destroys only cancerous cells. C. Provides complete relief of symptoms of cancer. D. Delays the spread of cancer to other sites.
