Question 1 of 5
A client prescribed fluoxetine (Prozac) returns to the clinic one week after beginning therapy and states, "This drug is not working, I am still very sad." Which of the following would be the nurse's best response?
Correct Answer: D
Rationale: Fluoxetine, an SSRI, typically takes 4-6 weeks for full antidepressant effects. Adding drugs, switching early, or expecting results in 1-3 weeks is premature.
Question 2 of 5
The nurse is preparing to administer enoxaparin (Lovenox) to a client before hip replacement surgery. Which of the following conditions would prevent the nurse from administering this drug?
Correct Answer: B
Rationale: A bleeding disorder contraindicates enoxaparin due to hemorrhage risk. It's used for DVT/PE prevention, and a HR of 60 is normal.
Question 3 of 5
Which of the following would the nurse correctly include in client teaching about nitroglycerin (Nitrostat)?
Correct Answer: A,B,C,D
Rationale: Sublingual use, proper storage, timely replacement, and posture precautions ensure nitroglycerin efficacy and safety. Headaches are common and not a reason to stop.
Question 4 of 5
The nurse is teaching the client prescribed verapamil to avoid which of the following foods?
Correct Answer: A
Rationale: Grapefruit increases verapamil levels by inhibiting metabolism, risking toxicity. Apples, bananas, and oranges have no significant interaction.
Question 5 of 5
The nurse is caring for a client with a medical prescription for clozapine [Clozaril]. The nurse knows which of the following is the priority laboratory value that should be reviewed prior to medication administration?
Correct Answer: A
Rationale: Clozapine risks agranulocytosis; monitoring WBC count is critical before administration. Other labs are less urgent.
