Question 1 of 5
A female client who has a history of seizures went to a healthcare facility to ask the nurse regarding the use of birth control pills while on phenytoin therapy. The nurse correctly states to the client that:
Correct Answer: A
Rationale: Phenytoin induces liver enzymes that increase the metabolism of oral contraceptives, reducing their effectiveness. This increases the risk of unintended pregnancy. Pregnancy is not prohibited, but effective contraception is essential. Discontinuing phenytoin is not recommended without medical advice. Therefore, the nurse should inform the client about the decreased effectiveness of birth control pills.
Question 2 of 5
A 22-year-old woman ingests an entire bottle of acetaminophen in an attempted suicide. She unexpectedly feels well; and when her boyfriend discovers what she has done, he takes her to the emergency department. Which of the following drugs should be given in the ER?
Correct Answer: B
Rationale: Acetaminophen overdose needs acetylcysteine , replenishing glutathione to detoxify NAPQI, preventing liver damage. Aspirin , bicarbonate , fomepizole , and penicillamine (E) don't apply. Early administration reverses her silent toxicity.

Question 4 of 5
The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?
Correct Answer: B
Rationale: Risperidone risks agranulocytosis, requiring blood monitoring . This statement shows understanding of a critical safety step, indicating effective education. Nightmares , weight loss , and metallic taste aren't key concerns. B ensures safety, making it the best indicator.
Question 5 of 5
ACE inhibitors:
Correct Answer: D
Rationale: ACE inhibitors increase bradykinin by blocking its breakdown, not decrease it, so that's false. Hyperkalemia is more common in diabetes due to renal issues, not less, making that false. They're not absolutely contraindicated with NSAIDs, though caution applies, so that's incorrect. They decrease efferent arteriolar resistance, reducing glomerular pressure, a true statement, key in renoprotection. They don't reduce prostaglandins (NSAIDs do). This hemodynamic effect is vital in hypertension and diabetic nephropathy.
