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."
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. 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.
Correct Answer is ["8"]
Explanation
To calculate the flow rate in drops per minute (gtt/min), we first need to find the total number of drops (gtt) that will be infused over 3 hours and then divide by the total infusion time in minutes.
Given: Volume to infuse = 150 mL
Infusion time = 3 hours
Drop factor = 10 gtt/mL
First, let's find the total number of drops for the entire infusion:
Total drops = Volume × Drop factor
Total drops = 150 mL × 10 gtt/mL = 1500 drops
Now, let's find the infusion time in minutes: Infusion time (in minutes) = 3 hours × 60 minutes/hour = 180 minutes
Finally, let's calculate the flow rate:
Flow rate (gtt/min) = Total drops / Infusion time
Flow rate = 1500 drops / 180 minutes ≈ 8.33 gtt/min
Rounded to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 8 gtt/min.
