Extract:
Question 1 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg 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
Rationale: 1. Convert weight from pounds to kilograms: Child's weight = 66 lb, Conversion factor: 1 kg = 2.2 lb, 66 lb ÷ 2.2 = 30 kg. 2. Calculate the total weekly dose: Prescribed dose = 0.24 mg/kg/week, 30 kg × 0.24 mg/kg = 7.2 mg/week. 3. Determine the daily dose: The dose is given six times per week, 7.2 mg ÷ 6 = 1.2 mg/day. The nurse should administer 1.2 mg of somatropin per dose subcutaneously to the child.
Question 2 of 5
A nurse is reinforcing teaching about the iPLEDGE program with a female client who has a new prescription for isotretinoin. The nurse should tell the client that which of the following is a requirement of the program?
Correct Answer: D
Rationale: Isotretinoin is not associated with cervical cancer risk, and this requirement is not part of the iPLEDGE program. Mammogram is not a requirement of the iPLEDGE program. While vitamin A supplementation may be recommended, it is not a specific requirement of the iPLEDGE program. This is a key requirement of the iPLEDGE program due to the teratogenic effects of isotretinoin.
Question 3 of 5
A nurse is preparing to administer gentamicin to a child who weighs 44 lb. The provider prescribes 6 mg/kg/day IV to be administered in three equal doses. Available is gentamicin 40 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 1
Rationale:
To answer this question, the nurse needs to perform the following steps: Convert the child's weight from pounds to kilograms by dividing 44 by 2.2. The result is 20 kg. Calculate the total daily dose of gentamicin by multiplying 6 mg/kg by 20 kg. The result is 120 mg/day. Divide the total daily dose by three to get the dose for each administration. The result is 40 mg/dose. Calculate the volume of gentamicin to be administered by dividing 40 mg by 40 mg/mL. The result is 1 mL/dose.
Therefore, the nurse should administer 1 mL of gentamicin with each dose.
Question 4 of 5
A nurse is preparing to administer medications to a client through an enteral feeding tube. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Medications should be administered separately to ensure proper absorption and effectiveness. This action helps prevent aspiration during medication administration but is not specific to enteral feeding tube administration. Flushing the tube with normal saline helps ensure that the entire medication dose reaches the client and prevents tube blockage. This action is not necessary and may disrupt the flow of the medication.
Question 5 of 5
A nurse is reinforcing teaching with the family of a client who has a new prescription for donepezil. Which of the following therapeutic effects should the nurse inform the family to expect?
Correct Answer: A
Rationale: Donepezil is used to treat Alzheimer's disease and is expected to improve cognitive function. Donepezil is not indicated for pulmonary function improvement. Donepezil is not primarily used for seizure control. Donepezil does not typically affect urinary output.
