Nursing Elites

1. The client with chronic renal failure is receiving hemodialysis. Which of the following laboratory values should the nurse monitor closely?

• A. Hemoglobin level.
• B. Blood urea nitrogen (BUN) level.
• C. Serum potassium level.
• D. Creatinine level.

Correct answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

2. A client with chronic kidney disease missed dialysis yesterday to attend a funeral. The client's wife calls the home health nurse and reports that her husband is lethargic and hard to arouse. Which instruction is most important for the nurse to provide?

• A. Apply the client's home oxygen.
• B. Check for a thrill and bruit at the client's dialysis access site.
• C. Ensure the client avoids salt intake for the rest of the day.
• D. Take the client to the emergency department (ED).

Correct answer: D

Rationale: In this scenario, the most crucial instruction for the nurse to provide is to take the client to the emergency department (ED). Missing dialysis can lead to severe complications in clients with chronic kidney disease, such as electrolyte imbalances and fluid overload. Lethargy and difficulty in arousing the client suggest a critical situation that requires immediate medical attention. Applying home oxygen, checking the dialysis access site, and ensuring salt intake avoidance, although important, are not as urgent as seeking emergency care to address the potential severe complications from missed dialysis.

3. After educating a client with a history of renal calculi, the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?

• A. I should drink at least 3 liters of fluid every day.
• B. I will eliminate all dairy or sources of calcium from my diet.
• C. Aspirin and aspirin-containing products can lead to stones.
• D. The doctor can give me antibiotics at the first sign of a stone.

Correct answer: A

Rationale: To prevent the formation of renal calculi, it is essential to maintain adequate hydration as dehydration can contribute to the precipitation of minerals leading to stone formation. Therefore, the correct statement indicating understanding of the teaching is choice A. Increasing fluid intake helps dilute urine and reduces the risk of stone formation. Eliminating all sources of calcium is not recommended as calcium is essential for various bodily functions and eliminating it can lead to other health issues. Aspirin and aspirin-containing products do not directly cause kidney stones. Antibiotics are not used to prevent or treat renal calculi, as they are not caused by bacterial infections.

4. Prior to administering tissue plasminogen activator (t-PA), the nurse should assess the client for which of the following contraindications to administering the drug?

• A. Age over 60 years.
• B. History of cerebral hemorrhage.
• C. History of heart failure.
• D. Cigarette smoking.

Correct answer: B

Rationale: The correct answer is B: History of cerebral hemorrhage. A history of cerebral hemorrhage is a contraindication to t-PA administration because of the increased risk of bleeding. Choices A, C, and D are incorrect. Age over 60 years is not a contraindication for t-PA administration. While older age may pose some risks, it is not an absolute contraindication. History of heart failure is not a direct contraindication to t-PA administration. Cigarette smoking, while a risk factor for cardiovascular disease, is not a specific contraindication for t-PA administration.

5. A client has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?

• A. Pulse rate
• B. Blood pressure
• C. Pulmonary artery systolic pressure
• D. Pulmonary artery end-diastolic pressure

Correct answer: A

Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.
