Question 1 of 5
A female client with mild depression reports to the nurse of recently starting St. John's wort. Which information provided by the client requires further instruction? Which information provided by the client requires further instruction?
Correct Answer: D
Rationale: St. John’s wort induces cytochrome P450 enzymes, reducing the efficacy of hormonal contraceptives. The client’s statement that no additional contraception is needed is incorrect, requiring instruction to use alternative methods to prevent pregnancy.
Question 2 of 5
A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition? Which condition should the nurse review the medical record for?
Correct Answer: C
Rationale: Methylphenidate, a stimulant, can increase blood pressure and heart rate, exacerbating hypertension. Reviewing the medical record for hypertension ensures safe administration and prevents cardiovascular complications.

How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.) How many mL should the nurse administer?
Correct Answer: 0.8
Rationale: Dose = 80 mg; concentration = 60 mg/0.6 mL = 100 mg/mL; volume = 80 mg ÷ 100 mg/mL = 0.8 mL.
Question 4 of 5
