Nursing Elites

1. In a patient with chronic kidney disease (CKD) receiving erythropoietin therapy, what laboratory result should the nurse monitor to evaluate the effectiveness of this therapy?

• A. Serum creatinine
• B. White blood cell count
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is C: Hemoglobin level. Erythropoietin therapy is used to stimulate red blood cell production in patients with chronic kidney disease who often develop anemia due to reduced erythropoietin production by the kidneys. Monitoring the hemoglobin level is essential to evaluate the effectiveness of erythropoietin therapy as an increase in hemoglobin indicates improved red blood cell production and better management of anemia in these patients. Serum creatinine, white blood cell count, and serum potassium levels are important parameters to monitor in CKD patients but are not specific indicators of the effectiveness of erythropoietin therapy for managing anemia.

2. A 50-year-old man presents with progressive jaundice, dark urine, and pruritus. Imaging reveals a mass in the head of the pancreas. What is the most likely diagnosis?

• A. Pancreatic cancer
• B. Chronic pancreatitis
• C. Gallstones
• D. Primary sclerosing cholangitis

Correct answer: A

Rationale: The presentation of progressive jaundice, dark urine, and pruritus along with a pancreatic mass, particularly in the head of the pancreas, strongly suggests pancreatic cancer as the most likely diagnosis. These symptoms are classic for obstructive jaundice caused by a mass in the head of the pancreas, making pancreatic cancer the most fitting choice.

3. A 65-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

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

Correct answer: C

Rationale: The combination of weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels strongly suggests pancreatic cancer. The presentation is classic for pancreatic malignancy, which commonly presents with obstructive jaundice due to the tumor blocking the common bile duct, leading to elevated bilirubin and alkaline phosphatase levels. Weight loss is a common symptom of advanced pancreatic cancer. The palpable mass in the right upper quadrant corresponds to the location of the pancreas. Gallstones typically manifest with different symptoms, while hepatitis and primary biliary cirrhosis are less likely to present with a palpable mass and weight loss in this scenario.

4. A patient with type 1 diabetes is prescribed insulin glargine. What is the primary characteristic of this insulin?

• A. Rapid-acting
• B. Intermediate-acting
• C. Long-acting
• D. Short-acting

Correct answer: C

Rationale: Insulin glargine is classified as a long-acting insulin. It is designed to provide a consistent level of insulin over approximately 24 hours, helping to keep blood glucose levels stable throughout the day. This long duration of action makes it suitable for basal insulin replacement in patients with type 1 diabetes, providing a background level of insulin to mimic the body's natural release of insulin between meals and overnight.

5. What instruction should be provided to a client with a history of myocardial infarction (MI) who is prescribed nitroglycerin?

• A. Take nitroglycerin with food to avoid stomach upset.
• B. Store nitroglycerin tablets in a dark, glass container.
• C. Swallow nitroglycerin tablets whole without chewing.
• D. Discontinue the medication if a headache occurs.

Correct answer: B

Rationale: Nitroglycerin is a medication that should be stored in a dark, glass container to protect it from light and moisture. Exposure to light and moisture can reduce its effectiveness. Storing it in a dark, glass container helps maintain the medication's stability and potency, ensuring that it remains safe and effective for use in emergencies, such as angina attacks.
