A nurse is preparing to administer lithium 300 mg PO every 8 hr. Available is lithium carbonate 150 mg capsules. How many capsules should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
2
Rationale
To calculate how many capsules the nurse should administer, divide the total dose by the dose per capsule. In this case, 300 mg ├À 150 mg = 2 capsules. The correct answer is 2 because each capsule contains 150 mg of lithium carbonate, and the total dose required is 300 mg. Choice A would be incorrect as it does not follow the calculation. Other choices are incorrect as they do not align with the proper calculation method of dividing the total dose by the dose per capsule.
