Showing 10 questions, Sign in for moreA nurse is preparing to administer prednisolone 2 mg/kg/day PO divided in equal doses every 12 hr to a toddler who has acute asthma and weighs 26lb. Available is prednisolone syrup 15 mg/5 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.)
Explanation
Step-by-Step Solution:
Convert the toddler's weight from pounds to kilograms.
1 pound= 0.453592 kilograms.
26 pounds = 26 x 0.453592 = 11.793592 kilograms.
Calculate the total daily dose of prednisolone.
The prescribed dose is 2 mg/kg/day.
The toddler weighs 11.793592 kg.
Total daily dose = 2 mg/kg/day x 11.793592 kg = 23.587184 mg/day.
Determine the dose per administration.
Total daily dose is divided into two equal doses (every 12 hours).
The dose per administration = 23.587184 mg/day / 2 = 11.793592 mg per dose.
Calculate the volume of prednisolone syrup to administer.
The available prednisolone syrup is 15 mg/5 ml.
To find the volume, we can set up a proportion:
15 mg / 5 ml = 11.793592 mg / x ml
Cross-multiplying:
15x = 5 x 11.793592
Solving for x:
x = (5 x 11.793592) / 15 = 3.931197 ml
Round the answer to the nearest tenth.
​​3.9 mL
A nurse is preparing to administer dimercaprol 3 mg/kg IM to an adolescent who weighs 79 lb. Available is dimercaprol injection 100 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.)
Explanation
Step-by-Step Solution:
Convert the adolescent's weight from pounds to kilograms.
1 pound is = 0.453592 kilograms.
79 pounds = 79 x 0.453592 = 35.793592 kilograms.
Calculate the total dose of dimercaprol.
The prescribed dose is 3 mg/kg.
The adolescent weighs 35.793592 kg.
The total dose = 3 mg/kg x 35.793592 kg = 107.380776 mg.
Calculate the volume of dimercaprol injection to administer.
The available dimercaprol injection is 100 mg/mL.
To find the volume, we can set up a proportion:
100 mg / 1 mL = 107.380776 mg / x mL
Cross-multiplying:
100x = 107.380776
Solving for x:
x = 107.380776 / 100 = 1.07380776 mL
Round the answer to the nearest tenth: 1.1 mL.
A nurse is preparing to administer morphine 0.1 mg/kg IM to a school-age child who weighs 88 Ib. The amount available is morphine 4 mg/mL. How many ml should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step-by-Step Solution:
Convert the child's weight from pounds to kilograms.
1 pound is approximately 0.453592 kilograms.
88 pounds = 88 x 0.453592 = 39.916736 kilograms.
Calculate the total dose of morphine.
The prescribed dose is 0.1 mg/kg.
The child weighs 39.916736 kg.
Total dose = 0.1 mg/kg x 39.916736 kg = 3.9916736 mg.
Calculate the volume of morphine injection to administer.
The available morphine injection is 4 mg/mL.
To find the volume, we can set up a proportion:
4 mg / 1 mL = 3.9916736 mg / x mL
Cross-multiplying:
4x = 3.9916736
Solving for x:
x = 3.9916736 / 4 = 0.9979184 mL
Round the answer to the nearest whole number: 1 mL
A nurse is preparing to administer dextrose 5% in water 40 mL IV to infuse over 20 min to a child. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Step-by-Step Solution:
Determine the total infusion time in hours.
The infusion time is 20 minutes.
There are 60 minutes in an hour.
The infusion time in hours = 20 minutes / 60 minutes/hour = 0.3333 hours.
Calculate the infusion rate in mL/hr.
The total volume to be infused is 40 mL.
The infusion time is 0.3333 hours.
The infusion rate = 40 mL / 0.3333 hours = 120 mL/hr.
A nurse is preparing to administer ibuprofen 10 mg/kg PO every 6 to 8 hr PRN pain to a child who weighs 55 lb. Available is ibuprofen suspension 100 mg/5 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.)
Explanation
Step-by-Step Solution:
Convert the child's weight from pounds to kilograms.
1 pound is= 0.453592 kilograms.
55 pounds = 55 x 0.453592 = 24.94756 kilograms.
Calculate the total dose of ibuprofen.
The prescribed dose is 10 mg/kg.
The child weighs 24.94756 kg.
The total dose = 10 mg/kg x 24.94756 kg = 249.4756 mg.
Calculate the volume of ibuprofen suspension to administer.
The available ibuprofen suspension is 100 mg/5 mL.
To find the volume, we can set up a proportion:
100 mg / 5 mL = 249.4756 mg / x mL
Cross-multiplying:
100x = 249.4756 x 5
Solving for x:
x = (249.4756 x 5) / 100 = 12.47378 mL
Round the answer to the nearest tenth.
12.5 mL.
A nurse is preparing to administer quinine 25 mg/kg/day PO divided in equal doses every 8 hr to a school-age child who weighs 86 lb. Available is quinine 325 mg tablets. How many tablets 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.)
Explanation
Step-by-Step Solution:
Convert the child's weight from pounds to kilograms.
1 pound is =0.453592 kilograms.
86 pounds = 86 x 0.453592 = 38.999952 kilograms.
Calculate the total daily dose of quinine.
The prescribed dose is 25 mg/kg/day.
The child weighs 38.999952 kg.
The total daily dose = 25 mg/kg/day x 38.999952 kg = 974.9988 mg/day.
Determine the dose per administration.
The total daily dose is divided into three equal doses (every 8 hours).
The dose per administration = 974.9988 mg/day / 3 = 324.9996 mg per dose.
Calculate the number of tablets to administer per dose.
Each tablet contains 325 mg of quinine.
To find the number of tablets, divide the dose per administration by the amount of quinine per tablet:
Number of tablets = 324.9996 mg / 325 mg/tablet = 0.999999 tablets
Round the answer to the nearest whole number: 1 tablet.
A nurse is preparing to administer 0.9% sodium chloride 250 mL IV to infuse over 4 hr to a school-age child. The nurse should ensure the IV pump is set 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.)
Explanation
Step-by-step calculation:
IV rate= Total volume/Time (hours)
250/4 =62.5 mL/hr
Round the answer off: 63L/hr
A nurse is caring for a school-age child who has a new prescription for an IV infusion of 250 mL lactated Ringers to run over 6 hr. The nurse should ensure the IV pump is set 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.)
Explanation
Identify the given information:
Volume of lactated Ringer's solution: 250 mL
Infusion time: 6 hours
Calculate the infusion rate in mL/hr:
Infusion rate = Volume / Time
Substitute the values:
Infusion rate = 250 mL / 6 hr
Calculate the result:
Infusion rate ≈ 41.67 mL/hr
Round the answer to the nearest whole number:
Infusion rate ≈ 42 mL/hr
A nurse is preparing to administer 1.5 tsp fluconazole oral suspension PO to a toddler who has systemic candidiasis. The nurse should recognize that this is equivalent to how many mL? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Identify the given information:
Volume of fluconazole oral suspension: 1.5 tsp
Use the conversion factor:
1 tsp = 5 mL
Set up the conversion:
1.5 tsp x (5mL / 1 tsp)
Calculate the result:
1.5 tsp x 5mL/tsp = 7.5 mL
Round the answer to the nearest tenth: 7.5 mL
A nurse is preparing to administer hydroxyzine 1 mg/kg IM to a school-age child who weighs 67 lb. Available is hydroxyzine injection 25 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.)
Explanation
Identify the given information:
Dose of hydroxyzine: 1.1 mg/kg
Weight of the child: 67 lb
Concentration of hydroxyzine injection: 25 mg/mL
Convert the child's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total dose of hydroxyzine in mg:
Total dose = Dose/kg x Weight (kg)
Substitute the values:
Total dose = 1.1 mg/kg x 67 lb x (0.453592 kg/1 lb)
Calculate the result:
Total dose ≈ 33.7 mg
Calculate the volume of hydroxyzine to be administered:
Volume = Total dose / Concentration
Substitute the values:
Volume = 33.7 mg / 25 mg/mL
Calculate the result:
Volume ≈ 1.348 mL
Round the answer to the nearest tenth:
Volume ≈ 1.3 mL
