A nurse is preparing to administer ketorolac 0.4 mg/kg IM to an adolescent who weighs
96.8 lb. The amount available is ketorolac 15 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: 1.2 mL
Rationale:
To calculate this dosage, first convert the adolescent's weight from pounds to kilograms:
96.8 lb ÷ 2.2 lb/kg = 44 kg. Then calculate the dose of ketorolac in mg: 0.4 mg/kg × 44
kg = 17.6 mg. Finally, divide the dose in mg by the concentration of the ketorolac to
find the volume to administer: 17.6 mg ÷ 15 mg/mL = 1.173 mL, which rounds to 1.2 mL
when rounded to the nearest tenth. The nurse should administer 1.2 mL of ketorolac IM.
A nurse is preparing to administer diazepam 0.3 mg/kg IV bolus to a toddler who
weighs 24 lb. Available is diazepam injection 5 mg/mL. How many mL should the nurse
administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies.
Do not use a trailing zero.)
✔️ Correct Answer: 0.65 mL
Rationale:
Step 1: Convert the toddler's weight from pounds to kilograms using the conversion
factor 1 kg = 2.2 lb: 24 lb ÷ 2.2 lb/kg = 10.91 kg. Step 2: Calculate the total amount of
,diazepam needed using the dosage of 0.3 mg/kg: 0.3 mg/kg × 10.91 kg = 3.27 mg. Step
3: Calculate the volume of diazepam injection to administer using the concentration of 5
mg/mL: 3.27 mg ÷ 5 mg/mL = 0.654 mL. Rounding to the nearest hundredth, the nurse
should administer 0.65 mL of diazepam injection IV bolus.
A nurse is preparing to administer 7.5 mL of ampicillin 250 mg oral suspension to a
toddler who has otitis media. The nurse should recognize that 7.5 mL is equivalent to
how many tsp? (Round the answer to the nearest tenth. Use a leading zero if it applies.
Do not use a trailing zero.)
✔️ Correct Answer: 1.5 tsp
Rationale:
To calculate this conversion, use the conversion factor that 1 teaspoon (tsp) is
equivalent to 5 mL. So, 7.5 mL × (1 tsp / 5 mL) = 1.5 tsp. The nurse should administer 1.5
tsp of ampicillin oral suspension.
A nurse is preparing to administer dextrose 5% in 0.9% sodium chloride 125 mL IV to
infuse over 15 min. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not
use a trailing zero.)
✔️ Correct Answer: 500 mL/hr
Rationale:
To calculate this, first convert the infusion time from minutes to hours: 15 min × (1 hr /
60 min) = 0.25 hr. Then, divide the volume of the infusion by the infusion time to find
the rate: 125 mL ÷ 0.25 hr = 500 mL/hr. The nurse should set the IV pump to deliver 500
mL/hr.
A nurse is preparing to administer dextrose 5% in water 800 mL IV to infuse over 6 hr to
an adolescent client. The nurse should set the IV pump to deliver how many mL/hr?
, (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not
use a trailing zero.)
✔️ Correct Answer: 133 mL/hr
Rationale:
To calculate this, divide the volume of the infusion by the infusion time to find the rate:
800 mL ÷ 6 hr = 133.33 mL/hr, which rounds to 133 mL/hr when rounded to the nearest
whole number. The nurse should set the IV pump to deliver 133 mL/hr.
A nurse is preparing to administer morphine 0.1 mg/kg IV bolus every 3 to 4 hr PRN for
pain to a school-age child who weighs 51 lb. Available is morphine injection 2 mg/mL.
How many mL should 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.)
✔️ Correct Answer: 1.2 mL
Rationale:
Step 1: Convert the child's weight from pounds to kilograms: 51 lb ÷ 2.2 = 23.18 kg.
Step 2: Calculate the total amount of morphine the child should receive per dose: 0.1
mg/kg × 23.18 kg = 2.318 mg. Step 3: Calculate the volume of morphine injection to be
administered: 2.318 mg ÷ 2 mg/mL = 1.159 mL. Rounding to the nearest tenth gives 1.2
mL. The nurse should administer 1.2 mL of morphine injection per dose.
A nurse is preparing to administer ephedrine 3 mg/kg/day IV bolus divided in equal
doses every 6 hr to a school-age child who weighs 70 lb. Available is ephedrine injection
50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to
the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
✔️ Correct Answer: 0.48 mL
Rationale:
Step 1: Convert the child's weight from pounds to kilograms: 70 lb ÷ 2.2 = 31.82 kg.
Step 2: Calculate the total daily dose of ephedrine in mg: 3 mg/kg/day × 31.82 kg/day =
95.45 mg/day. Step 3: Since the daily dose is divided into equal doses every 6 hours,
