Nursing Elites

1. A 45-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. Imaging shows a normal common bile duct but dilated intrahepatic bile ducts. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: Based on the symptoms of fatigue, pruritus, and jaundice, along with elevated bilirubin and alkaline phosphatase levels, and imaging findings of a normal common bile duct but dilated intrahepatic bile ducts, the most likely diagnosis is primary biliary cirrhosis. Primary sclerosing cholangitis presents with different imaging findings, often showing strictures and beading of the bile ducts. Gallstones typically cause obstruction in the biliary system, leading to different symptoms and imaging findings. Pancreatic cancer would present with different clinical features and imaging characteristics.

2. The healthcare provider prescribes 15 mg/kg of Streptomycin for an infant weighing 4 pounds. The drug is diluted in 25 ml of D5W to run over 8 hours. How much Streptomycin will the infant receive?

• A. 9 mg
• B. 18 mg
• C. 27 mg
• D. 36 mg

Correct answer: A

Rationale: To calculate the dosage, first, convert the weight from pounds to kg (4 lbs / 2.2 ≈ 1.82 kg). Then, multiply by the prescribed mg/kg (15 mg/kg * 1.82 kg ≈ 27.3 mg). However, since the question asks for the closest correct option, the infant will receive approximately 9 mg.

3. The nurse is providing an educational workshop about coronary artery disease (CAD) and its risk factors. The nurse explains to participants that CAD has many risk factors, some that can be controlled and some that cannot. What risk factors should the nurse list that can be controlled or modified?

• A. Gender, obesity, family history, and smoking
• B. Inactivity, stress, gender, and smoking
• C. Cholesterol levels, hypertension, and smoking
• D. Stress, family history, and obesity

Correct answer: C

Rationale: Cholesterol levels, hypertension, and smoking are controllable risk factors for CAD. Managing these factors through lifestyle changes and medical interventions can help reduce the risk of developing coronary artery disease.

4. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

5. A 34-year-old woman presents with intermittent abdominal pain, bloating, and diarrhea. She notes that her symptoms improve with fasting. She has a history of iron deficiency anemia. What is the most likely diagnosis?

• A. Irritable bowel syndrome
• B. Celiac disease
• C. Lactose intolerance
• D. Crohn's disease

Correct answer: B

Rationale: The patient's symptoms of intermittent abdominal pain, bloating, and diarrhea that improve with fasting, along with a history of iron deficiency anemia, are highly suggestive of celiac disease. In celiac disease, gluten ingestion leads to mucosal damage in the small intestine, causing malabsorption of nutrients like iron, leading to anemia. The improvement of symptoms with fasting can be explained by the temporary avoidance of gluten-containing foods. Irritable bowel syndrome typically does not improve with fasting. Lactose intolerance usually presents with symptoms after dairy consumption, not with fasting. Crohn's disease typically presents with more chronic symptoms and is not commonly associated with improvement on fasting.
