A nurse is preparing to administer fluoxetine 30 mg PO for a client who has depression and cannot swallow capsules. Available is fluoxetine 20 mg/5 mL oral solution.
How many mL should the nurse plan to administer?
(Round to the nearest tenth. Use a leading zero if it applies.)
The Correct Answer is ["7.5"]
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.

Correct Answer is A
Explanation
Choice A rationale:
Withholding the dose if having a fine hand tremor is not recommended. Hand tremors are a common side effect of lithium, but they can be managed by adjusting the dose.
Choice B rationale:
Avoiding foods with a high tyramine content is not necessary for lithium users. This dietary restriction is typically associated with certain antidepressants, not lithium.
Choice C rationale:
Limiting daily fluid intake is incorrect. Lithium can cause increased thirst and urination, so it’s important to maintain adequate hydration.
Choice D rationale:
Following a low-sodium diet is not advised. Both salt and fluid can affect the levels of lithium in your blood, so it’s important to consume a steady amount every day.
So, the correct answer is, none of the above.
