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. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?

A. Apply the patch to a different site each day.
B. Remove the patch at bedtime each day.
C. Apply the patch over an area with little or no hair.
D. Keep the patch on for 24 hours at a time.

Correct answer: B

Rationale: The correct instruction for a Nitroglycerin transdermal patch is to remove it each day, usually at bedtime, to prevent tolerance. Keeping the patch on for 24 hours at a time can lead to tolerance development. Applying the patch to a different site each day is not necessary, as long as the area is rotated to prevent skin irritation. Applying the patch over an area with little or no hair is not a critical instruction for the Nitroglycerin patch.

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

A. Brush and floss your teeth regularly.
B. Avoid drinking grapefruit juice.
C. Take this medication with food.
D. Increase your intake of calcium-rich foods.

Correct answer: A

Rationale: The correct answer is to instruct the client to brush and floss their teeth regularly. Phenytoin can lead to gingival hyperplasia, making oral hygiene crucial to prevent complications. Encouraging good oral care practices helps reduce the risk of adverse effects on the gums and teeth. Avoiding grapefruit juice is not specifically related to Phenytoin. While some medications require intake with food, Phenytoin is usually taken on an empty stomach for better absorption. Increasing calcium-rich foods is not directly associated with Phenytoin therapy.

4. What is a desired outcome of the drug Phenytoin?

A. Decrease symptoms of PTSD
B. Resolution of signs of infection
C. Decrease or cessation of seizures without excessive sedation
D. Prevention or relief of bronchospasm

Correct answer: C

Rationale: The correct answer is C: Decrease or cessation of seizures without excessive sedation. Phenytoin is primarily used as an antiepileptic medication to manage and prevent seizures. It does not directly impact symptoms of PTSD (Choice A), resolution of signs of infection (Choice B), or prevention or relief of bronchospasm (Choice D). Therefore, the desired outcome of Phenytoin is to control seizures effectively while avoiding excessive sedation.

5. Which medication is a beta blocker?

A. Atenolol (Tenormin)
B. Verapamil (Calan)
C. Captopril (Capoten)
D. Clopidogrel (Plavix)

Correct answer: A

Rationale: Atenolol (Tenormin) is a beta blocker commonly used to treat conditions like hypertension and angina by blocking the action of adrenaline on the heart. Verapamil is a calcium channel blocker, Captopril is an ACE inhibitor, and Clopidogrel is an antiplatelet medication. Therefore, the correct answer is Atenolol (Tenormin) as it belongs to the beta blocker class of medications.
