Nursing Elites

1. A 68-year-old man with a history of diabetes, hypertension, and coronary artery disease (s/p coronary artery bypass graft two years ago) presents to the emergency room with fevers and left-sided abdominal pain. His physical examination reveals a temperature of 101.5°F, pulse 96, and blood pressure of 135/80. His abdomen is soft with moderate left lower quadrant tenderness. There is no rebound or guarding. Bowel sounds are present. A CT scan is done which reveals inflammation around an area of the left colon. The next step in his workup/management should be

• A. Antibiotic therapy with ciprofloxacin and metronidazole
• B. Referral for urgent colonoscopy
• C. Referral to a surgeon for immediate hemicolectomy
• D. Barium enema

Correct answer: A

Rationale: The patient's presentation is consistent with diverticulitis without evidence of perforation or abscess formation on CT scan. During acute infections, procedures like barium enema and colonoscopy should be avoided to prevent the risk of perforation. Urgent surgery is not indicated initially. The appropriate next step is to start antibiotic therapy aimed at gram-negative aerobes and anaerobes, such as ciprofloxacin and metronidazole, which are the initial treatment of choice for diverticulitis.

2. 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.

3. Why is a client with ascites scheduled for a paracentesis procedure?

• A. To diagnose liver disease
• B. To relieve abdominal pressure
• C. To assess kidney function
• D. To reduce blood pressure

Correct answer: B

Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.

4. A client with newly diagnosed diabetes mellitus is receiving teaching on foot care. Which instruction should the nurse include?

• A. Walk barefoot whenever possible to toughen your feet.
• B. Soak your feet in hot water daily to improve circulation.
• C. Trim your toenails straight across to prevent ingrown toenails.
• D. Use a heating pad to keep your feet warm.

Correct answer: C

Rationale: Correctly trimming toenails straight across is crucial in preventing ingrown toenails and potential infections in individuals with diabetes. Ingrown toenails can lead to complications, so it is essential for diabetic clients to practice proper nail care to avoid these issues. Choices A, B, and D are incorrect. Walking barefoot can increase the risk of foot injuries, soaking feet in hot water can cause burns or skin damage, and using a heating pad can lead to burns or injuries due to decreased sensation in the feet, which is common in diabetes.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.
