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. Which lab result would be most indicative of renal failure?
- A. Elevated creatinine levels.
- B. Low potassium levels.
- C. Low calcium levels.
- D. High sodium levels.
Correct answer: A
Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.
3. 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.
4. A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?
- A. Albumin level of 2.5 g/dL
- B. Phosphorus level of 5 mg/dL
- C. Sodium level of 135 mmol/L
- D. Potassium level of 5.5 mmol/L
Correct answer: A
Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.
5. In a patient with chronic kidney disease, which of the following is a common complication?
- A. Hyperkalemia.
- B. Hypernatremia.
- C. Hypocalcemia.
- D. Hyperphosphatemia.
Correct answer: A
Rationale: Hyperkalemia is a common complication in chronic kidney disease due to the kidneys' reduced ability to excrete potassium. As kidney function declines, potassium levels may increase, leading to hyperkalemia. Hypernatremia (increased sodium levels), hypocalcemia (low calcium levels), and hyperphosphatemia (elevated phosphate levels) are not typically associated with chronic kidney disease. Therefore, the correct answer is hyperkalemia.
