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 A
Explanation
Choice A rationale
The symptoms described - right-sided numbness and weakness in the arm and leg, along with a distinct droop on the right side of the face - are indicative of a stroke. Immediate medical intervention is crucial in such cases. Initiating two large-bore IV catheters would allow for rapid administration of necessary medications and fluids. Reviewing the inclusion criteria for IV fibrinolytic therapy is also important, as this type of therapy can help dissolve the clot causing the stroke and restore blood flow to the brain.
Choice B rationale
While continuous observation for transient episodes of neurological dysfunction is important in the care of a patient with suspected stroke, it is not the first course of action. Immediate medical intervention to treat the stroke is the priority.
Choice C rationale
Elevating the head of the bed to 30 degrees can help reduce intracranial pressure in a patient with a stroke. However, this is not the first course of action. Immediate medical intervention to treat the stroke is the priority.
Choice D rationale
Administering aspirin can help prevent further clot formation and platelet aggregation in patients with certain types of stroke. However, aspirin is not typically the first line treatment in the acute phase of a stroke, especially when the type of stroke (ischemic or hemorrhagic) has not yet been determined.
Correct Answer is B
Explanation
Choice A rationale
Verifying that the nurse has gathered the necessary supplies is important, but it is not the most critical action in this scenario. The new nurse has already gathered the necessary supplies for the procedure.
Choice B rationale
This is the correct answer. A transparent dressing is preferred over a gauze dressing for securing an IV catheter. It allows for easy inspection of the insertion site for signs of infection.
Choice C rationale
Ensuring that the gauze dressing is taped securely in place is not the most critical action in this scenario. As mentioned, a transparent dressing is generally preferred for securing an IV catheter.
Choice D rationale
While inspecting the secured IV site after the insertion procedure is important, advising the nurse to use a transparent dressing over the site is a more immediate need. This will allow for continuous visual inspection of the site.
