A nurse is preparing to administer cefazolin 1g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min.
The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.). gtt/min.

Full Explanation
Step 1 is to calculate the total volume to be infused in mL/min. This is done by dividing the total volume (250 mL) by the time in minutes (30 min). So, 250 mL ÷ 30 min = 8.33 mL/min. Step 2 is to convert mL/min to gtt/min using the drop factor. So, (8.33 mL/min) × (10 gtt/mL) = 83.3 gtt/min. Round off to the nearest whole number, the correct answer is 83 gtt/min.

B. After reconstitution, the vial will contain a total of 500 mg of medication.
After reconstitution, the vial will contain 1 gram of medication, not 500 mg. So, choice B is incorrect.
C. Administer the medication within 1 hr of reconstitution.
The label does state to use the solution within 1 hour of reconstitution. So, choice C is correct.
D. This medication can only be administered IM. .

Full Explanation
Choice A rationale:
The label states to add 3.5 mL of diluent for reconstitution, not 5 mL. So, choice A is incorrect.
Choice B rationale:
After reconstitution, the vial will contain 1 gram of medication, not 500 mg. So, choice B is incorrect.
Choice C rationale:
The label does state to use the solution within 1 hour of reconstitution. So, choice C is correct.
Choice D rationale:
The label states the medication can be used for IM or IV, not only IM. So, choice D is incorrect.
A nurse is preparing to administer ketorolac 30 mg IM to a client.
Available is ketorolac injection 15 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.)
Full Explanation
Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 15 mg/mL.
So, we calculate 30 mg ÷ 15 mg/mL = 2 mL.
So the correct answer is 2 mL.
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?

Full Explanation
Step 1 is: (30 mg ÷ 20 mg/mL) Step 2 is: 1.5 mL Step 3 is: Round 1.5 mL to the nearest whole number = 2 mL
Final calculated answer: 2 mL
