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.)
The Correct Answer is ["1.2"]
To calculate the dose of somatropin to be administered per dose, we first need to convert the child's weight from pounds to kilograms. We can do this using the following conversion factor:
1 kg = 2.2 lbs
Therefore, the child's weight in kilograms is:
weight_kg = 66 lbs / 2.2 lbs/kg = 30 kg
Next, we can calculate the total dose of somatropin to be administered per week using the following formula:
total_dose = weight_kg * 0.24 mg/kg/week
This gives us a total dose of:
total_dose = 30 kg * 0.24 mg/kg/week = 7.2 mg/week
Finally, we can calculate the dose of somatropin to be administered per dose by dividing the total dose by the number of daily doses:
dose_per_dose = total_dose / 6 doses/day = 1.2 mg/dose
Therefore, the nurse should administer 1.2 mg of somatropin per dose.
Answer: 1.2 mg of somatropin per dose.

Correct Answer is D
Explanation
Choice A rationale:
Two loose stools in the past 24 hours could be a symptom of Clostridioides difficile infection, but it’s not necessarily a priority finding. The infection can cause diarrhea, but it’s not life-threatening.
Choice B rationale:
A WBC count of 11,000/mm³ is slightly elevated, indicating a possible infection. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice C rationale:
A heart rate of 104/min is slightly elevated, indicating possible stress or anxiety. However, it’s not necessarily a priority finding as it’s not significantly high.
Choice D rationale:
Creatinine level of 3.1 mg/dL is significantly high, indicating possible kidney damage, which can be a side effect of vancomycin treatment. This should be reported to the provider immediately.
Correct Answer is A
Explanation
Choice A rationale:
A respiratory rate of 10/min is lower than the normal range (12-20 breaths per minute for adults), indicating respiratory depression, which is a serious side effect of morphine and should be reported immediately.
Choice B rationale:
Facial flushing is a common side effect of morphine due to histamine release but it’s not life-threatening.
Choice C rationale:
Constipation is a common side effect of morphine and can be managed with laxatives and diet.
Choice D rationale:
Blood pressure 88/56 mm Hg is lower than the normal range (90/60mmHg to 120/80mmHg), indicating hypotension, which can be a side effect of morphine but it’s not as immediately life-threatening as respiratory depression.
