A physician orders Lithium 5 grams/day is three divided doses PO for a client with bipolar disorder. The medication is supplied 400 mg/5 mL. How much will the nurse administer per dose? (Round the answer to the nearest tenth Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["6.2"]
Total daily dose in mg:
1.5 grams/day = 1500 mg/day Dose per administration in mg:
1500 mg/day ÷ 3 doses/day = 500 mg/dose Volume to be administered per dose in mL:
(500 mg/dose) / (400 mg/5 mL) = 6.25 mL/dose
Rounding to the nearest tenth, the nurse will administer 6.2 mL per dose.

Correct Answer is ["0.5"]
Explanation
Volume to administer (mL)=( Desired dose (mcg)/Available concentration (mcg/mL) 100 mcg is in 2 mL, so the concentration is:
100 mcg/2 Ml =50 mcg/mL
Volume to administer =25 mcg/ 50 mcg/mL=0.5mL
So, the nurse will administer 0.5 mL of fentanyl for the correct dose.
