1. What is/are the possible cause(s) of acute pancreatitis in this patient?

Correct answer: B

Rationale: This patient presents with symptoms and lab findings consistent with acute pancreatitis. Cytomegalovirus is a common viral infection associated with pancreatitis. In patients with AIDS, the pancreas can be affected by various infections (e.g., cryptococcus, Mycobacterium tuberculosis, candida, Toxoplasma gondii) and medications (such as ddI, pentamidine, trimethoprim/sulfamethoxazole, metronidazole) can also lead to acute pancreatitis. While HIV infection predisposes individuals to various opportunistic infections, in this case, the most likely cause of the acute pancreatitis is cytomegalovirus infection.

2. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

3. A patient with chronic heart failure is prescribed carvedilol. What is the primary purpose of this medication?

Correct answer: C

Rationale: Carvedilol, a beta-blocker, is primarily prescribed in patients with chronic heart failure to decrease heart rate and reduce the workload on the heart. By lowering the heart rate, carvedilol helps the heart function more efficiently and improves symptoms in patients with heart failure.

4. The client is prescribed clozapine (Clozaril), and the nurse plans to educate them about its purpose. Which statement should the nurse provide?

Correct answer: B

Rationale: Clozapine (Clozaril) is an antipsychotic medication that is known to improve cognitive function and thought clarity in individuals with schizophrenia. It primarily helps in managing symptoms related to thought processes rather than focusing on community function, coping with symptoms, or grooming and hygiene.

5. When implementing patient teaching for a patient admitted with hyperglycemia and newly diagnosed diabetes mellitus scheduled for discharge the second day after admission, what is the priority action for the nurse?

Correct answer: C

Rationale: The priority action for the nurse when time is limited is to focus on essential teaching. In this scenario, the patient should be educated on how to self-monitor glucose levels and administer medications to control glucose levels. This empowers the patient with immediate skills for managing their condition. Instructing about the increased risk of cardiovascular disease (choice A) is important but not as urgent as teaching self-monitoring and medication administration. Providing detailed information about dietary glucose control (choice B) can be beneficial but is secondary to ensuring the patient can monitor and manage their glucose levels. Teaching about the effects of exercise (choice D) is relevant but not as critical as immediate self-monitoring and medication administration education.
