A client with neuroleptic malignant syndrome receives a prescription for dantrolene 1.5 mg/kg IV. The client weighs 132 pounds.
The label on the 250 mg vial reads, “Reconstitute with 5 mL sterile water for injection, USP. Reconstitution yields 50 mg/mL.”. How many mL should the nurse administer?
The Correct Answer is ["1.8"]
The client weighs 132 pounds. To convert pounds to kilograms, divide the weight in pounds by
2.2. So, the client’s weight in kilograms is: Step 1: 132 pounds ÷ 2.2 = 60 kg The prescription for dantrolene is 1.5 mg/kg. To find out how many milligrams the client should receive, multiply the client’s weight in kilograms by the dosage in mg/kg: Step 2: 60 kg × 1.5 mg/kg = 90 mg The vial is reconstituted to yield a concentration of 50 mg/mL. To find out how many mL the nurse should administer, divide the total dosage in milligrams by the concentration in mg/mL: Step 3: 90 mg ÷ 50 mg/mL = 1.8 mL So, the nurse should administer 1.8 mL of dantrolene.

Correct Answer is ["6.8"]
Explanation
Step 1: Convert the client’s weight from lbs to kg. 1 kg is approximately 2.2 lbs. So, 198 lbs ÷
2.2 = 90 kg (rounded to the nearest whole number).
Step 2: Calculate the total mcg of Dopamine needed per minute. The prescription is for 2 mcg/kg/minute. So, 90 kg × 2 mcg/kg/minute = 180 mcg/minute.
Step 3: Convert the total mcg of Dopamine in the bag to mcg/mL. The bag contains 400 mg of Dopamine in 250 mL. 1 mg is equal to 1000 mcg. So, 400 mg × 1000 = 400,000 mcg. Therefore, the concentration is 400,000 mcg ÷ 250 mL = 1600 mcg/mL.
Step 4: Calculate the mL of Dopamine needed per minute. So, 180 mcg/minute ÷ 1600 mcg/mL
= 0.1125 mL/minute.
Step 5: Convert mL/minute to mL/hour. There are 60 minutes in an hour. So, 0.1125 mL/minute × 60 = 6.75 mL/hour. The IV pump should be set to deliver 6.8 mL/hour (rounded to the nearest tenth).
