Correct Answer is ["2.1"]
Explanation
First, we need to calculate the total daily dose of tobramycin for the client. The total daily dose is calculated as follows:
Total daily dose = Dose per kg per day x Weight Total daily dose = 3 mg/kg/day x 85 kg Total daily dose = 255 mg/day
Since the total daily dose is divided into three doses, each dose will be:
Each dose = Total daily dose / Number of doses Each dose = 255 mg / 3 Each dose = 85 mg
Now, we need to convert this dose into mL. We know that we have tobramycin 40 mg/mL, so:
Volume to administer = Each dose / Concentration Volume to administer = 85 mg / 40 mg/mL Volume to administer = 2.125 mL
Rounding this to the nearest tenth, we get 2.1 mL.
Correct Answer is ["56"]
Explanation
Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.
