Correct Answer is C
Explanation
Choice A rationale:
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.
Choice B rationale:
Regular dental appointments are important as phenytoin can cause gum hyperplasia. This statement does not indicate a need for further teaching.
Choice C rationale:
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.
Choice D rationale:
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.
Correct Answer is ["0.5"]
Explanation
Step 1 is to determine the amount of lorazepam that needs to be administered, which is 1 mg.
Step 2 is to calculate the volume of lorazepam oral solution needed to deliver this dose. This is done using the formula:
Dose (mg) ÷ Concentration (mg/mL)
Given that the solution has a concentration of 2 mg/mL, we calculate:
1 mg ÷ 2 mg/mL = 0.5 mL
Therefore, the nurse should administer 0.5 mL of lorazepam oral solution.
