A child with an Escherichia coli urinary tract infection is receiving a secondary infusion of gentamicin 60 mg every 8 hours IV, which is to be infused over 30 minutes.
The medication is delivered by the pharmacy diluted in a 50 ml bag of saline.
What should be the infusion pump’s regulation in mL/hour? (Provide the numeric value only.)
The Correct Answer is ["100"]
Step 1: The child is receiving gentamicin 60 mg every 8 hours IV, which is to be infused over 30 minutes. The medication is delivered by the pharmacy diluted in a 50 ml bag of saline.
Step 2: We need to find the infusion pump’s regulation in mL/hour.
Step 3: Since the medication is to be infused over 30 minutes, we convert this to hours by dividing by 60. So, 30 minutes is 0.5 hours.
Step 4: The rate of infusion is then the total volume (50 mL) divided by the time in hours (0.5 hours).
Step 5: So, the infusion pump’s regulation is (50 mL ÷ 0.5 hours) = 100 mL/hour.

Correct Answer is B
Explanation
Choice A rationale
Suggesting that the child participate in a team sport to encourage socialization is not the best response. Duchenne muscular dystrophy (DMD) is a progressive disease that causes muscle weakness and loss of muscle mass. Participating in a team sport could be physically challenging for the child and could potentially lead to injury.
Choice B rationale
Encouraging the parents to allow the child to continue attending swimming lessons with supervision is the best response. Swimming is a low-impact exercise that can help maintain muscle strength and flexibility in children with DMD. It also provides an opportunity for socialization.
Choice C rationale
Explaining that the child is too young to understand the risks associated with swimming is not the best response. Children with DMD can participate in swimming with appropriate supervision and safety measures in place.
Choice D rationale
Providing a list of alternative activities that are less likely to cause the child to experience fatigue is not the best response. While it’s important to consider activities that are appropriate for the child’s physical abilities, it’s also important to consider the child’s interests. The child has expressed a desire to continue swimming, and with appropriate supervision, this activity can be beneficial.
Correct Answer is B
Explanation
Choice A rationale
A blood glucose level of 90 mg/dL (5 mmol/L) is within the normal range and would not need to be reported to the surgeon.
Choice B rationale
A serum creatinine level of 5 mg/dL (442 µmol/L) is significantly elevated, indicating impaired kidney function. This is a critical lab value that should be reported to the surgeon immediately, as it could impact the patient’s ability to safely undergo surgery and recover postoperatively.
Choice C rationale
A hemoglobin level of 13 g/dL (130 g/L) is within the normal range and would not need to be reported to the surgeon.
Choice D rationale
A potassium level of 4 mEq/L (4 mmol/L) is within the normal range and would not need to be reported to the surgeon.
