Question 1 of 5
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: Solution: 150 mg is to 1 capsule as 300 mg is to x capsules. So 150 / 1 = 300 / x. Cross-multiplying: 150x = 300. Dividing both sides by 150: x = 2.
Therefore the nurse should administer 2 capsules per dose.

A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.8
Rationale: Solution: Volume (mL) = Dose (mg) / Concentration (mg/mL). Dose = 30 mg Concentration = 40 mg/mL. So Volume = 30 mg / 40 mg/mL = 0.75 mL rounded to 0.8 mL.
