The patient weighs 38 pounds, and the concentration of the medication is 50 mg/mL. How many mL will the nurse administer to the patient? Round to the nearest tenths place. Record numerical answer only.
Explanation
Convert the patient's weight from pounds (lb) to kilograms (kg).
Weight in kg = 38 lb / 2.2 lb/kg
= 17.2727 kg.
Calculate the total desired dose in milligrams (mg).
Desired dose (mg) = Desired dose (mg/kg) × Weight (kg)
= 6.25 mg/kg × 17.2727 kg
= 107.954 mg.
Available concentration of the medication = 50 mg/mL.
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 107.954 mg / 50 mg/mL
= 2.15908 mL.
Round the answer to the nearest tenths place.
= 2.2 mL.

A child weighs 52 lb. The child has a fever and the doctor orders acetaminophen. The safe dose range of this medication is 10-15 mg/kg every 6 hours. What is the maximum safe daily dose of the medication the client can receive? Round to the nearest whole number. Record numerical answers only.
Explanation
Convert the child's weight from pounds (lb) to kilograms (kg).
Weight in kg = 52 lb / 2.2 lb/kg
= 23.636 kg.
Maximum safe dose per kilogram per administration = 15 mg/kg.
Calculate the maximum single dose in milligrams (mg).
Maximum single dose (mg) = Maximum dose per administration (mg/kg) × Weight (kg)
= 15 mg/kg × 23.636 kg
= 354.54 mg.
Determine the number of times the medication can be administered per day.
Given every 6 hours, Number of doses per day = 24 hours / 6 hours/dose
= 4 doses/day.
Calculate the maximum safe daily dose of the medication.
Maximum safe daily dose (mg) = Maximum single dose (mg) × Number of doses per day
= 354.54 mg × 4 doses
= 1418.16 mg.
Round the answer to the nearest whole number.
= 1418 mg.
The nurse is checking a newborn for the presence of Ortolani maneuver and Barlow sign. For which health problem are these assessments used?
A child with a bacterial infection is prescribed penicillin. The provider orders 25,000 units/kg/day of penicillin to be given every four hours. The client weighs 56.9 lb. How many units will the nurse administer to the client for one dose? Round to the nearest whole number. Record numerical answer only.
Explanation
Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 56.9 lb / 2.2 lb/kg
= 25.8636 kg.
Calculate the total daily dose in units.
Total daily dose (units) = Prescribed dose (units/kg/day) × Weight (kg)
= 25,000 units/kg/day × 25.8636 kg
= 646590 units/day.
Determine the number of doses per day.
Doses are given every 4 hours, so Number of doses per day = 24 hours / 4 hours/dose
= 6 doses/day.
Calculate the dose per administration in units.
Dose per administration (units) = Total daily dose (units) / Number of doses per day
= 646590 units / 6 doses
= 107765 units.
On the second day after a surgical repair for a cleft lip, which of the following would be most important?
A client who weighs 76.5 kg is ordered hydromorphone 0.2 mg/kg/day intravenous push divided as needed every 6 hours. Available supply is 1 mg/mL. How many milliliters would the nurse administer in one dose? Round the answer to the nearest tenths place. Record the numeric answers only.
Explanation
Calculate the total daily desired dose in milligrams (mg).
Total daily desired dose (mg) = Desired dose (mg/kg/day) × Weight (kg)
= 0.2 mg/kg/day × 76.5 kg
= 15.3 mg/day.
Determine the number of doses per day.
Doses are ordered every 6 hours, so Number of doses per day = 24 hr / 6 hr
= 4 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily desired dose (mg) / Number of doses per day
= 15.3 mg / 4 doses
= 3.825 mg.
Available concentration of the medication = 1 mg/mL.
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose per administration (mg) / Available concentration (mg/mL)
= 3.825 mg / 1 mg/mL
= 3.825 mL.
Round the answer to the nearest tenths place.
= 3.8 mL.
The nurse is closely monitoring the intake and output of an infant with heart failure who is receiving diuretic therapy. Which of the following is the most appropriate method to assess urine output?
A nurse is administering 30 mg/kg/day of amoxicillin every six hours to a 48.6 lb client. The concentration available is 0.2 g/5 mL. How many mL will the nurse administer to the client per dose? Round to the nearest tenths place. Record numerical answer only.
Explanation
Convert the client's weight from pounds (lb) to kilograms (kg).
Weight in kg = 48.6 lb / 2.2 lb/kg
= 22.09 kg.
Calculate the total daily desired dose in milligrams (mg).
Total daily desired dose (mg) = Desired dose (mg/kg/day) × Weight (kg)
= 30 mg/kg/day × 22.09 kg
= 662.7 mg/day.
Determine the number of doses per day.
Doses are administered every six hours, so Number of doses per day = 24 hours / 6 hours/dose
= 4 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily desired dose (mg) / Number of doses per day
= 662.7 mg / 4 doses
= 165.675 mg.
Convert the available concentration from grams (g) to milligrams (mg).
Available concentration = 0.2 g/5 mL
1 g = 1000 mg
Available concentration in mg/mL = (0.2 g × 1000 mg/g) / 5 mL
= 200 mg / 5 mL
= 40 mg/mL.
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose per administration (mg) / Available concentration (mg/mL)
= 165.675 mg / 40 mg/mL
= 4.141875 mL.
Round the answer to the nearest tenths place.
= 4.1mL
