A nurse is preparing to administer morphine oral solution 30 mg PO for breakthrough pain to a client who has cancer.
Available is morphine oral solution 20 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 20 mg/mL.
So, we calculate 30 mg ÷ 20 mg/mL = 1.5 mL. Rounded to the nearest tenth, this is 1.5 mL.
So the correct answer is 1.5 mL.

Correct Answer is ["33"]
Explanation
Step 1: Calculate the total volume to be administered. The total volume is the volume of the drug (ceftriaxone 1 g) which is in 0.9% sodium chloride 100 mL. So, the total volume is 100 mL.
Step 2: Calculate the total time for the drug to be administered. The drug is to be administered over 45 minutes.
Step 3: Calculate the flow rate in mL/min. The flow rate is the total volume divided by the total time. So, the flow rate is (100 mL ÷ 45 min) = 2.22 mL/min.
Step 4: Calculate the flow rate in gtt/min. The flow rate in gtt/min is the flow rate in mL/min multiplied by the drop factor. The drop factor is 15 gtt/mL. So, the flow rate in gtt/min is (2.22 mL/min × 15 gtt/mL) = 33.33 gtt/min.
Step 5: Round the answer to the nearest whole number. The flow rate in gtt/min rounded to the nearest whole number is 33 gtt/min.
So, the nurse should set the IV flow rate to deliver 33 gtt/min.
Correct Answer is ["9.4"]
Explanation
Step 1 is to calculate the dose to be administered which is 300 mg. Step 2 is to calculate the concentration of the available medication which is 160 mg/5 mL. Step 3 is to calculate the volume to be administered as (300 mg ÷ (160 mg/5mL)) = 9.375 mL.
So, the correct answer is, after analyzing all steps, the nurse should administer 9.4 mL per dose (rounded to the nearest tenth).
