Correct Answer is D

Explanation

Choice A rationale:

Switching brands of phenytoin can lead to variations in drug absorption and serum drug levels, potentially leading to a loss of seizure control or toxicity. Therefore, this is not a correct instruction.

Choice B rationale:

Altering the phenytoin administration regimen each week can lead to fluctuations in serum drug levels, potentially leading to a loss of seizure control or toxicity. Therefore, this is not a correct instruction.

Choice C rationale:

Phenytoin does not turn urine blue. This is a side effect associated with some other medications, but not phenytoin. Therefore, this is not a correct instruction.

Choice D rationale:

Alcohol can increase serum phenytoin levels, potentially leading to toxicity. Therefore, this is a correct instruction.

So, the correct answer is D. Alcohol increases the chance of phenytoin toxicity.

Correct Answer is ["7.5"]

Explanation

To calculate the volume of fluoxetine to administer, we need to use the formula for dose conversion.

Step 1 is to set up the equation: 30 mg (desired dose) ÷ (20 mg/5 mL). This simplifies to 30 mg × (5 mL/20 mg). The mg units cancel out, leaving us with the volume in mL.

So, the correct answer is 7.5 mL.
