Nursing Elites

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

• A. HIV
• B. Cytomegalovirus
• C. Dideoxyinosine (ddI)
• D. Pentamidine

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. The nurse is caring for four clients: Client A, who has emphysema and an oxygen saturation of 94%; Client B, with a postoperative hemoglobin of 8.7 g/dL; Client C, newly admitted with a potassium level of 3.8 mEq/L; and Client D, scheduled for an appendectomy with a white blood cell count of 15,000/mm3. What intervention should the nurse implement?

• A. Increase Client A's oxygen to 4 liters per minute via nasal cannula.
• B. Determine if Client B has two units of packed cells available in the blood bank.
• C. Ask the dietitian to add a banana to Client C's breakfast tray.
• D. Inform Client D that surgery is likely to be delayed until the infection is treated.

Correct answer: D

Rationale: A high white blood cell count, as seen in Client D, indicates infection, which may require postponing surgery to treat the infection adequately. It is crucial to address the underlying infection before proceeding with the appendectomy to prevent complications and ensure a successful surgical outcome.

3. A patient with chronic obstructive pulmonary disease (COPD) is experiencing severe dyspnea. What position should the nurse encourage the patient to assume?

• A. Supine
• B. Prone
• C. High Fowler's
• D. Trendelenburg

Correct answer: C

Rationale: The High Fowler's position is the most appropriate position for a patient with COPD experiencing severe dyspnea. This position helps improve lung expansion and reduce dyspnea by allowing the diaphragm to move more freely and increasing the efficiency of breathing. It also helps reduce the work of breathing and enhances oxygenation in patients with COPD. Supine position (Choice A) may worsen dyspnea by limiting lung expansion. Prone position (Choice B) is not ideal for COPD patients experiencing severe dyspnea as it may restrict breathing. Trendelenburg position (Choice D) is not recommended for COPD patients with dyspnea as it can further compromise breathing.

4. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

5. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.
