3. The order is for 50 mg of meperidine IM. Available on the unit is meperidine 75 mg/ml. How much should the nurse administer? 1. 0.67 ml. 2. 0.75 ml. 3. 1.33 ml. 4. 1.5 ml. Answer: ____________________________________________________________

Answer 1

1) Answer : Rate of IV infusion is 25 gtts/minute

Total Volume = 1000 ml

Drop factor = 12 gtts/ml

Time in minute =( 8 × 60) = 480 minutes

Rate ( drops per minute) = ?

Use the following formula

Drops per minute =

Drops per minute =  

Drops per minute =

Rate of IV infusion = 25 gtts/minute

2) Answer : The nurse should record the intake as 1050 ml

Here total intake given as = 4 oz water + 6 oz orange juice + 10 oz ginger ale + 300 ml apple juice + 5 oz water

Intake = 4 oz + 6 oz + 10 oz + 300 ml + 5 oz

Intake = 25 oz + 300 ml

To convert oz to ml, Consider 1 oz fluid = 30 ml

ie,Intake = ( 25×30) ml + 300 ml

Intake = 750 ml + 300 ml

Intake = 1050 ml

3) Answer : The nurse should administer 0.67 ml of meperidine

(Medicine order is 50 mg IM, available medicine is 75 mg/ml)

Medication dosage = × Quantity

( Here "desired" is the prescribed dosage, "available" is the dosage strength as stated on medication label, "quantity" is the volume in which the dosage strength available in milliliters.

So Medication dosage =   ×

Medicine dose = 0.66667 ml

Medicine dose = 0.67 ml
