Nursing Elites

1. A 40-year-old man presents with abdominal pain, diarrhea, and weight loss. He has a history of Crohn's disease. Laboratory tests reveal low hemoglobin and elevated ESR. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Crohn's disease flare

Correct answer: D

Rationale: The symptoms of abdominal pain, diarrhea, weight loss, along with the history of Crohn's disease, and the laboratory findings of low hemoglobin and elevated ESR, strongly suggest a Crohn's disease flare. These clinical manifestations are classic features of a flare-up in a patient with a known history of Crohn's disease.

2. A patient with heart failure is prescribed digoxin. What is the most important instruction the nurse should provide?

• A. Take an extra dose if you miss one.
• B. Avoid high-potassium foods.
• C. Report any visual disturbances.
• D. Stop taking the medication if your pulse is normal.

Correct answer: C

Rationale: The correct answer is C: 'Report any visual disturbances.' Patients taking digoxin should be instructed to report any visual disturbances, as this can be a sign of digoxin toxicity. Visual disturbances like changes in color vision, blurred vision, or seeing halos around lights can indicate an overdose of digoxin. Choices A, B, and D are incorrect. Instructing a patient to take an extra dose if they miss one can lead to overdose. Avoiding high-potassium foods is important for patients on potassium-sparing diuretics, not digoxin. Stopping the medication if the pulse is normal is incorrect, as the pulse rate alone is not an indicator of digoxin effectiveness or toxicity.

3. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.

4. A client from a nursing home is admitted with urinary sepsis and has a single-lumen, peripherally-inserted central catheter (PICC). Four medications are prescribed for 9:00 a.m. and the nurse is running behind schedule. Which medication should the nurse administer first?

• A. Piperacillin/tazobactam (Zosyn) in 100 ml D5W, IV over 30 minutes q8 hours.
• B. Vancomycin (Vancocin) 1 gm in 250 ml D5W, IV over 90 minutes q12 hours.
• C. Pantoprazole (Protonix) 40 mg PO daily.
• D. Enoxaparin (Lovenox) 40 mg subq q24 hours.

Correct answer: A

Rationale: In a patient with urinary sepsis, administering Piperacillin/tazobactam first is crucial as it is an antibiotic that directly targets the infection. Addressing the infection promptly is essential to prevent its progression and complications. Vancomycin, Pantoprazole, and Enoxaparin are important medications for the patient's overall treatment plan, but in this scenario, the antibiotic should take precedence due to the urgency of managing the sepsis.

5. A 48-year-old man presents with fatigue, weight gain, and cold intolerance. Laboratory tests reveal high TSH and low free T4 levels. What is the most likely diagnosis?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Thyroiditis
• D. Thyroid cancer

Correct answer: A

Rationale: The scenario describes a classic presentation of hypothyroidism, supported by the laboratory findings of high TSH and low free T4 levels. In hypothyroidism, the body's thyroid hormone levels are inadequate, leading to symptoms like fatigue, weight gain, and cold intolerance. High TSH is a compensatory mechanism by the body to increase thyroid hormone production, which is deficient, resulting in a negative feedback loop. Therefore, the correct answer is hypothyroidism.
