1. A nurse is assessing a client who has a new prescription for chlorpromazine to treat schizophrenia. The client has a mask-like facial expression and is experiencing involuntary movements and tremors. Which of the following medications should the nurse anticipate administering?

• A. Amantadine
• B. Bupropion
• C. Phenelzine
• D. Hydroxyzine

Correct Answer: A

Rationale: The correct answer is Amantadine. Amantadine is used to treat extrapyramidal symptoms, such as mask-like facial expressions, involuntary movements, and tremors, which are common side effects of antipsychotic medications like chlorpromazine. Bupropion is an antidepressant and not indicated for treating these symptoms. Phenelzine is a monoamine oxidase inhibitor used for depression and anxiety disorders, not for extrapyramidal symptoms. Hydroxyzine is an antihistamine used for anxiety and allergic conditions, not for the side effects described in the client.

2. A nurse on a medical unit is preparing to administer alendronate 40 mg PO for an older adult client who has Paget's disease of the bone. Which of the following actions should be the nurse's priority?

• A. Administer the medication to the client before breakfast in the morning.
• B. Assist the client to a chair before administering the medication.
• C. Give the medication to the client with water rather than milk.
• D. Educate the client on how to take the medication at home.

Correct Answer: A

Rationale: The correct answer is to administer the medication to the client before breakfast in the morning. Alendronate should be taken on an empty stomach before breakfast to ensure optimal absorption. Choice B is incorrect because assisting the client to a chair is not directly related to the administration of alendronate. Choice C is incorrect as there is no specific requirement to avoid taking alendronate with milk. Choice D is also incorrect as the priority at this moment is the correct administration of the medication in the hospital setting.

3. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?

• A. Increases blood pressure
• B. Prevents esophageal bleeding
• C. Decreases heart rate
• D. Reduces ammonia levels

Correct Answer: D

Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.

4. A nurse is teaching a newly licensed nurse about contraindications to ceftriaxone. The nurse should include that a severe allergy to which of the following medications is a contraindication to ceftriaxone?

• A. Gentamicin
• B. Clindamycin
• C. Piperacillin
• D. Sulfamethoxazole-trimethoprim

Correct Answer: C

Rationale: The correct answer is C. Ceftriaxone, a cephalosporin antibiotic, has a cross-sensitivity with penicillin antibiotics like piperacillin. Therefore, a severe allergy to penicillin or penicillin-related antibiotics would be a contraindication to ceftriaxone. Choices A, B, and D are incorrect because they are not associated with a known cross-sensitivity with ceftriaxone.

5. A client with peptic ulcer disease reports a headache. Which of the following medications should the nurse plan to administer?

• A. Ibuprofen
• B. Naproxen
• C. Aspirin
• D. Acetaminophen

Correct Answer: D

Rationale: Acetaminophen is the preferred analgesic for clients with peptic ulcer disease because it does not cause gastrointestinal irritation, unlike Ibuprofen, Naproxen, and Aspirin, which can exacerbate peptic ulcer symptoms and lead to gastrointestinal complications.
