A nurse is preparing to administer lithium 300 mg PO to a client who has bipolar disorder. Available is lithium 150 mg capsules. How many capsules should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
D
Rationale
To administer 300 mg of lithium PO using 150 mg capsules, the nurse should divide the desired dose by the dose per capsule. 300 mg ├À 150 mg = 2 capsules. Rounding to the nearest whole number, the nurse should administer 2 capsules (Option D). Option A is incorrect as it would not provide the full dose. Option B is incorrect as it would be an insufficient dose. Option C is incorrect as it would also not provide the full dose.
