A nurse is teaching a client who has a new prescription for disulfiram. Which of the following information should the nurse include in the teaching?

"Do not drink alcohol while taking this medication."

"Do not crush this medication before swallowing."

"Avoid grapefruit juice while taking this medication."

"Take this medication with food."

Answer and Explanation

The Correct Answer is A

A. "Do not drink alcohol while taking this medication": Disulfiram is a medication used to deter alcohol consumption by producing unpleasant effects, such as nausea, vomiting, and flushing, if alcohol is consumed. Therefore, it is crucial for the client to abstain from alcohol while taking disulfiram to avoid these adverse reactions.

B. "Do not crush this medication before swallowing": While it is generally important not to alter the formulation of medications unless instructed by a healthcare provider or indicated in the medication's instructions, crushing disulfiram is not typically a concern. However, the primary focus of disulfiram therapy is the avoidance of alcohol, rather than specific administration instructions.

C. "Avoid grapefruit juice while taking this medication": Grapefruit juice is known to interact with certain medications by inhibiting cytochrome P450 enzymes in the liver, affecting drug metabolism. However, there is no significant interaction between disulfiram and grapefruit juice. Therefore, this information is not relevant to disulfiram therapy.

D. "Take this medication with food": Disulfiram is typically taken on an empty stomach, as food can interfere with its absorption. Therefore, advising the client to take disulfiram with food is not accurate and may compromise its effectiveness. The primary concern with disulfiram therapy is adherence to abstinence from alcohol.

Correct Answer is B

Explanation

A. Clamping the catheter: Clamping the catheter may interrupt the flow of fluids or medications, which could worsen the client's condition. This action is not appropriate as the first intervention.

B. Initiate oxygen therapy: Acute shortness of breath is a critical symptom that requires immediate intervention to ensure adequate oxygenation. Initiating oxygen therapy is the priority action to improve the client's oxygenation status while further assessment and interventions are conducted.

C. Auscultate breath sounds: Assessing breath sounds is an essential component of the assessment for a client experiencing shortness of breath. However, in this scenario, the priority is to ensure the client's oxygenation needs are met by initiating oxygen therapy first.

D. Position the client in left lateral Trendelenburg: Positioning the client in left lateral Trendelenburg may help optimize oxygenation by improving blood flow and ventilation-perfusion matching. However, this action is not the priority compared to initiating oxygen therapy, which directly addresses the client's respiratory distress.

A. Avoid flossing the teeth to prevent gum irritation. B. Alcohol increases the chance of phenytoin toxicity. C. Take an antacid with the medication if indigestion occurs. D. Phenytoin turns urine blue.

Correct Answer is B

Explanation

A. Avoid flossing the teeth to prevent gum irritation: There is no evidence to suggest that flossing the teeth increases the risk of gum irritation with phenytoin use. In fact, proper dental hygiene, including flossing, is essential to prevent gum disease, which can be exacerbated by the medication.

B. Alcohol increases the chance of phenytoin toxicity: Consumption of alcohol can increase the risk of phenytoin toxicity by enhancing its effects. Therefore, clients taking phenytoin should avoid alcohol consumption to prevent adverse effects and ensure the medication's efficacy.

C. Take an antacid with the medication if indigestion occurs: Phenytoin can interact with antacids, reducing its absorption and effectiveness. Therefore, clients should not take antacids concurrently with phenytoin unless directed by their healthcare provider.

D. Phenytoin turns urine blue: Phenytoin does not typically cause changes in urine color. This statement is incorrect and not relevant to the client's medication regimen.
