Full Explanation
Step 1: Determine how many milligrams are in each milliliter of the suspension.
- Total milligrams ÷ Total milliliters
- 25 mg ÷ 5 mL = 5 mg/mL
Step 2: Determine how many milliliters are needed to administer 75 mg.
- Desired milligrams ÷ Milligrams per milliliter
- 75 mg ÷ 5 mg/mL = 15 mL

A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/mL. The nurse should set the manual IV infusion 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.)
Full Explanation
Step 1 is to determine the total volume to be infused in minutes. This is done by multiplying the total volume by the drop factor: (1000 mL ÷ 480 min) × 15 gtt/mL = 31.25 gtt/min.
A nurse is reinforcing teaching with a client who has a new prescription for phenytoin.
The nurse should recognize that which of the following statements by the client indicates a need for further teaching?.
A. "I will notify my provider before taking any other medications.”.
The client should indeed notify their provider before taking any other medications, as phenytoin can interact with many other drugs. This statement does not indicate a need for further teaching.
B. "I have made an appointment to see my dentist next week.”.
Regular dental appointments are important as phenytoin can cause gum hyperplasia. This statement does not indicate a need for further teaching.
C. "I'll be glad when my seizures stop so I can quit taking this medicine.”.
This statement indicates a misunderstanding. Phenytoin is used to control seizures, not cure them. The client should not stop taking the medication when their seizures stop.
D. "I will take this medication with meals.”.
Phenytoin can be taken with or without food, but it should be taken consistently in the same manner. This statement does not indicate a need for further teaching. So, the correct answer is C, after analyzing all choices.
