1. The nurse is assessing a client with chronic kidney disease (CKD). Which finding is most important for the nurse to respond to first?
- A. Potassium 6.0 mEq/L.
- B. Daily urine output of 400 ml.
- C. Peripheral neuropathy.
- D. Uremic fetor.
Correct answer: A
Rationale: The correct answer is A. Potassium level of 6.0 mEq/L indicates hyperkalemia, which is a critical electrolyte imbalance in clients with chronic kidney disease. Hyperkalemia can lead to life-threatening arrhythmias, making it the priority finding to address. Choice B, a daily urine output of 400 ml, may indicate decreased kidney function but does not pose an immediate life-threatening risk compared to hyperkalemia. Peripheral neuropathy (Choice C) and uremic fetor (Choice D) are common manifestations of CKD but are not as urgent as addressing a potentially fatal electrolyte imbalance like hyperkalemia.
2. A client has a serum potassium level of 6.5 mmol/L, a serum creatinine level of 2 mg/dL, and a urine output of 350 mL/day. What is the best action by the nurse?
- A. Place the client on a cardiac monitor immediately.
- B. Teach the client to limit high-potassium foods.
- C. Continue to monitor the client’s intake and output.
- D. Ask to have the laboratory redraw the blood specimen.
Correct answer: A
Rationale: The best immediate action by the nurse in this situation is to place the client on a cardiac monitor immediately. A serum potassium level of 6.5 mmol/L indicates hyperkalemia, which can lead to life-threatening dysrhythmias. Monitoring the cardiac status is crucial to detect any potential arrhythmias promptly. Teaching the client to limit high-potassium foods (Choice B) may be important for long-term management, but it is not the priority at this moment. Continuing to monitor intake and output (Choice C) is important for assessing renal function but does not address the immediate risk of dysrhythmias. Asking to have the laboratory redraw the blood specimen (Choice D) is unnecessary since the current results indicate a critical situation that requires immediate action.
3. An older adult client with a long history of chronic obstructive pulmonary disease (COPD) is admitted with progressive shortness of breath and a persistent cough. The client is anxious and complaining of a dry mouth. Which intervention should the nurse implement?
- A. Assist the client to an upright position
- B. Administer a prescribed sedative
- C. Apply a high-flow Venturi mask
- D. Encourage the client to drink water
Correct answer: A
Rationale: Assisting the client to an upright position is the most appropriate intervention in this scenario. An upright position helps optimize lung expansion and aids in improving ventilation, which can alleviate shortness of breath. This position also assists in reducing anxiety by providing a sense of control and comfort. Administering a sedative (Choice B) may further depress the respiratory drive in a client with COPD and should be avoided unless absolutely necessary. Applying a high-flow Venturi mask (Choice C) may be indicated later based on oxygenation needs, but the immediate focus should be on positioning. Encouraging the client to drink water (Choice D) may not directly address the respiratory distress and anxiety experienced by the client.
4. A patient has been taking spironolactone (Aldactone) to treat heart failure. The nurse will monitor for
- A. hyperkalemia.
- B. hypermagnesemia.
- C. hypocalcemia.
- D. hypoglycemia.
Correct answer: A
Rationale: The correct answer is A: hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in heart failure management. One of the major side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the blood. Monitoring for hyperkalemia is crucial as it can lead to serious cardiac arrhythmias. Choices B, C, and D are incorrect. Hypermagnesemia (choice B) is not typically associated with spironolactone use. Hypocalcemia (choice C) and hypoglycemia (choice D) are also not directly linked to the use of spironolactone in heart failure treatment.
5. A client with chronic renal failure is prescribed a low-protein diet. The nurse should explain to the client that the purpose of this diet is to:
- A. Prevent fluid overload.
- B. Reduce the workload on the kidneys.
- C. Prevent dehydration.
- D. Maintain electrolyte balance.
Correct answer: B
Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.
