1. A healthcare professional is caring for a group of clients receiving antimicrobial therapy. Which of the following clients should the professional plan to monitor for manifestations of antibiotic toxicity?

A. An adolescent client with a sinus infection
B. An older adult client with prostatitis
C. A client who is postpartum with mastitis
D. A middle-aged client with a urinary tract infection

Correct answer: B

Rationale: An older adult client with prostatitis who is receiving antibiotics should be monitored for toxicity due to age-related reductions in medication metabolism and excretion. Older adults are more susceptible to antibiotic toxicity, making them a high-risk group for adverse effects.

2. What is the classification of Ondansetron?

A. Antihypertensive
B. Antiarrhythmic
C. Antiemetic
D. Antiulcer agent

Correct answer: C

Rationale: Ondansetron is classified as an antiemetic. It is commonly used to prevent nausea and vomiting, especially in patients undergoing chemotherapy or surgery. Choice A, Antihypertensive, is incorrect as Ondansetron is not used to treat high blood pressure. Choice B, Antiarrhythmic, is incorrect as Ondansetron is not used to manage heart rhythm abnormalities. Choice D, Antiulcer agent, is incorrect as Ondansetron is not primarily indicated for treating ulcers.

3. A client has a new prescription for Lovastatin. Which of the following instructions should the nurse include?

A. Take this medication on an empty stomach.
B. Take this medication in the morning.
C. Take this medication at bedtime.
D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: The correct instruction for taking Lovastatin is to take it at bedtime. Cholesterol production in the liver is highest at night, so taking Lovastatin at bedtime aligns with the body's natural rhythm and maximizes its effectiveness.

4. A healthcare professional is preparing to administer Diltiazem IV to a client who has atrial fibrillation. Which of the following findings should the healthcare professional report immediately?

A. Bradycardia.
B. Hypertension.
C. Shortness of breath.
D. Tachycardia.

Correct answer: A

Rationale: The correct answer is bradycardia. Diltiazem, a calcium channel blocker, can lead to bradycardia as a side effect. Bradycardia should be reported immediately because it can result in serious cardiac complications, especially in a client with atrial fibrillation. Hypertension, shortness of breath, and tachycardia are not typically associated with Diltiazem administration and would not be immediate concerns in this scenario.

5. Which of the following is commonly used to treat migraine headaches?

A. Beta-blockers
B. Cholinesterase Inhibitors
C. ACE inhibitors
D. Anti-epileptic drugs (AEDs)

Correct answer: D

Rationale: Anti-epileptic drugs (AEDs) are often used in the management of migraine headaches due to their ability to help prevent or reduce the frequency and intensity of migraines. They work by stabilizing electrical activity in the brain, which can help in controlling migraine symptoms. While beta-blockers are also sometimes used in migraine prevention, anti-epileptic drugs are more commonly associated with migraine treatment. Cholinesterase Inhibitors are not typically used for migraine headaches, as they are more commonly associated with conditions like Alzheimer's disease. ACE inhibitors are a type of medication used to treat conditions like high blood pressure and heart failure, but they are not a first-line treatment for migraines.
