1. When a client has a new prescription for Warfarin, which of the following foods should they avoid based on the nurse's instructions?
- A. Broccoli
- B. Bananas
- C. Chicken
- D. Potatoes
Correct answer: A
Rationale: Clients prescribed Warfarin should avoid foods high in vitamin K, like broccoli, as they can counteract the medication's effectiveness. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming high vitamin K foods can interfere with its anticoagulant effects. Bananas, chicken, and potatoes are not high in vitamin K and do not have a significant impact on Warfarin therapy.
2. A client with end-stage cancer receiving Morphine is prescribed Methylnaltrexone. The client's daughter asks why the provider prescribed Methylnaltrexone. Which of the following responses should the nurse make?
- A. The medication will increase your mother's respirations.
- B. The medication will prevent dependence on the Morphine.
- C. The medication will relieve your mother's constipation.
- D. The medication works with the Morphine to increase pain relief.
Correct answer: C
Rationale: The correct response is C: 'The medication will relieve your mother's constipation.' Methylnaltrexone is an opioid antagonist used to treat severe constipation unrelieved by laxatives in opioid-dependent clients. It works by blocking the mu opioid receptors in the GI tract, which helps alleviate constipation without affecting pain relief or causing withdrawal symptoms. Choices A, B, and D are incorrect. Methylnaltrexone's primary action is related to managing constipation rather than increasing respirations, preventing dependence on Morphine, or enhancing pain relief when used alongside Morphine.
3. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?
- A. These medications work by inhibiting enzymes to prevent HIV replication.
- B. These medications work by preventing protein synthesis within the HIV cell.
- C. These medications work by weakening the cell wall of the HIV virus.
- D. These medications work by blocking HIV entry into cells.
Correct answer: A
Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.
4. A client has been prescribed a new oral hypoglycemic agent for diabetes. Which of the following statements by the client indicates a need for further teaching?
- A. I will take this medication with my evening snack.
- B. I will monitor my blood sugar levels before each meal.
- C. I will take this medication as soon as I wake up.
- D. I will follow my exercise plan as usual.
Correct answer: A
Rationale: Taking an oral hypoglycemic agent with an evening snack may lead to hypoglycemia during the night. It is important to follow the prescribed timing for medication administration to maintain blood sugar levels within the target range. The medication is usually taken before meals to help control postprandial blood glucose levels effectively. Choice B is correct as monitoring blood sugar levels before each meal is a good practice. Choice C is incorrect as taking the medication upon waking up may align with certain oral hypoglycemic agents' dosing schedules. Choice D is also correct as regular exercise is an important part of managing diabetes.
5. A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The healthcare provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?
- A. Bursitis
- B. Sinusitis
- C. Depression
- D. Glaucoma
Correct answer: D
Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Choosing option D, Glaucoma, as the correct answer is crucial for the client's safety and to prevent exacerbation of their eye condition. Options A, B, and C are not contraindications for Oxybutynin use and are unrelated to the pharmacological effects of this medication.
