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. A client has driven himself to the emergency department. He is 50 years old, has a history of hypertension, and informs the nurse that his father died from a heart attack at age 60. The client has indigestion. The nurse connects him to an electrocardiogram monitor and begins administering oxygen at 2 L/min via nasal cannula. What should the nurse do next?

• A. Call for the physician.
• B. Start an IV infusion.
• C. Obtain a portable chest radiograph.
• D. Draw blood for laboratory studies.

Correct answer: B

Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.

4. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?

• A. As a single-dose 200 mEq oral tablet
• B. As an intravenous bolus over 15 to 20 minutes
• C. In an intravenous solution at a rate of 10 mEq/hour
• D. In an intravenous solution at a rate of 45 mEq/hour

Correct answer: C

Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.

5. A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?

• A. Check the client’s digoxin (Lanoxin) level.
• B. Administer an anti-nausea medication.
• C. Ask if the client can eat crackers.
• D. Refer the client to a gastrointestinal specialist.

Correct answer: A

Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.
