Nursing Elites

1. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

2. A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: When a patient is prescribed lisinopril, an ACE inhibitor, the nurse should monitor for hyperkalemia. Lisinopril can cause hyperkalemia by decreasing aldosterone secretion, which leads to potassium retention in the body. Hyperkalemia is a potential side effect of ACE inhibitors and should be closely monitored, as it can have serious consequences such as affecting cardiac function.

3. A 65-year-old female client arrives in the emergency department with shortness of breath and chest pain. The nurse accidentally administers 10 mg of morphine sulfate instead of the prescribed 4 mg. Later, the client's respiratory rate is 10 breaths/minute, oxygen saturation is 98%, and she states her pain has subsided. What is the legal status of the nurse?

• A. The nurse is guilty of negligence and will be sued.
• B. The client would not be able to prove malpractice in court.
• C. The nurse is protected by the Good Samaritan Act.
• D. The healthcare provider should have given the morphine sulfate dose.

Correct answer: B

Rationale: The correct answer is B because, in this scenario, the client would not be able to prove malpractice in court. Despite the nurse administering a higher dose of morphine than prescribed, the client's respiratory rate, oxygen saturation, and pain relief indicate that no harm resulted from the error. Therefore, the client would not have legal grounds to pursue a malpractice case against the nurse.

4. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

5. A 48-year-old woman presents with fatigue, pruritus, and jaundice. She has a history of ulcerative colitis. Laboratory tests reveal elevated bilirubin and alkaline phosphatase. What is the most likely diagnosis?

• A. Hepatitis B
• B. Primary biliary cirrhosis
• C. Primary sclerosing cholangitis
• D. Autoimmune hepatitis

Correct answer: C

Rationale: The combination of symptoms (fatigue, pruritus, jaundice) along with a history of ulcerative colitis and elevated bilirubin and alkaline phosphatase levels suggests primary sclerosing cholangitis. Primary sclerosing cholangitis is commonly associated with inflammatory bowel disease, such as ulcerative colitis. It is characterized by inflammation and fibrosis of the bile ducts, leading to cholestasis and elevated alkaline phosphatase and bilirubin levels.
