A nurse is preparing to give clindamycin 1,200 mg IV bolus over 1 hr to a patient who is allergic to penicillin.
Available is clindamycin 1,200 mg in dextrose 5% in water 100 mL. The drop factor on the manual IV tubing is 15 gtt/mL. The nurse should set the flow rate to deliver how many gtt/min?
The Correct Answer is ["25"]
Step 1: Calculate the total volume of the IV solution. The available clindamycin is 1,200 mg in dextrose 5% in water 100 mL. So, the total volume is 100 mL.
Step 2: Calculate the time for the IV bolus. The medication will be given over 1 hour. So, the time is 60 minutes.
Step 3: Calculate the flow rate in mL/min. The flow rate is the total volume divided by the time. So, the flow rate is 100 mL ÷ 60 min = 1.67 mL/min.
Step 4: Calculate the flow rate in gtt/min. The drop factor on the manual IV tubing is 15 gtt/mL. So, the flow rate in gtt/min is 1.67 mL/min × 15 gtt/mL = 25 gtt/min. Therefore, the nurse should set the flow rate to deliver 25 gtt/min.

Correct Answer is ["2"]
Explanation
Step 1: The available ampicillin is in a 500 mg vial. The package insert instructs to add 1.8 mL of sterile water to yield ampicillin 250 mg/mL.
Step 2: We need to administer 500 mg of ampicillin. Step 3: The concentration of the solution is 250 mg/mL.
Step 4: To find out how many mL should the nurse administer per dose, we divide the required dose by the concentration.
Step 5: So, 500 mg ÷ 250 mg/mL = 2 mL. The nurse should administer 2 mL per dose.
Correct Answer is ["1"]
Explanation
Step 1: Calculate the number of tablets. The available medication is in 37.5 mg tablets, so 75 mg/day ÷ 2 ÷ 37.5 mg/tablet = 1 tablet (rounded to the nearest whole number).
