The nurse is caring for a patient who had kidney transplantation several years ago. Which of the following findings may indicate that the patient is experiencing adverse effects to the prescribed corticosteroid?
- A. Joint pain
- B. Tachycardia
- C. Postural hypotension
- D. Increase in creatinine level
Correct Answer: A
Rationale: Aseptic necrosis of the weight-bearing joints can occur when patients take corticosteroids over a prolonged period. Increased creatinine level, orthostatic dizziness, and tachycardia are not caused by corticosteroid use.

The nurse is caring for a patient who has had progressive chronic kidney disease (CKD) for several years and is starting hemodialysis. Which of the following information about diet should the nurse include in patient teaching?
- A. Increased calories are needed because glucose is lost during hemodialysis.
- B. Unlimited fluids are allowed since retained fluid is removed during dialysis.
- C. More protein will be allowed because of the removal of urea and creatinine by dialysis.
- D. Dietary sodium and potassium are unrestricted because these levels are normalized by dialysis.
Correct Answer: C
Rationale: Once the patient is started on dialysis and nitrogenous wastes are removed, there is less protein lost, therefore more protein in the diet is encouraged. Fluids are still restricted to avoid excessive weight gain and complications such as shortness of breath. Glucose is not lost during hemodialysis. Sodium and potassium intake continues to be restricted to avoid the complications associated with high levels of these electrolytes.
The nurse is caring for a patient with acute kidney injury (AKI) who has an arterial blood pH of 7.30 Which of the following assessment findings should the nurse anticipate?
- A. Vasodilation
- B. Poor skin turgor
- C. Bounding pulses
- D. Rapid respirations
Correct Answer: D
Rationale: Patients with metabolic acidosis caused by AKI may have Kussmaul's respirations as the lungs try to regulate carbon dioxide. Bounding pulses and vasodilation are not associated with metabolic acidosis. Because the patient is likely to have fluid retention, poor skin turgor would not be a finding in AKI.
The nurse is caring for a patient who is receiving hemodialysis and has symptoms of nausea, vomiting, and sudden onset of confusion. Which of the following actions is priority?
- A. Infuse a hypotonic solution.
- B. Increase the rate of the dialysis.
- C. Administer an antiemetic medication.
- D. Stop the dialysis solution.
Correct Answer: D
Rationale: The patient's symptoms suggest disequilibrium syndrome, which is a rare complication of modern HD and develops as a result of very rapid changes in the composition of the extracellular fluid. Urea, sodium, and other solutes are removed more rapidly from the blood than from the cerebrospinal fluid and the brain. This creates a high osmotic gradient in the brain resulting in the shift of fluid into the brain, causing cerebral edema. Manifestations include nausea, vomiting, confusion, restlessness, headaches, twitching and jerking, and seizures. Treatment consists of slowing or stopping dialysis and infusing hypertonic saline solution, albumin, or mannitol to draw fluid from the brain cells back into the systemic circulation.
The nurse is caring for a patient with diabetes who has been admitted with pneumonia and is prescribed gentamicin 60 mg IV. Which of the following parameters should the nurse monitor to evaluate the patient for adverse effects of the medication?
- A. Urine osmolality
- B. Serum potassium and sodium
- C. Blood glucose level
- D. Blood urea nitrogen (BUN) and creatinine
Correct Answer: D
Rationale: When a patient at risk for chronic kidney disease (CKD) receives a nephrotoxic medication, it is important to monitor renal function with BUN and creatinine levels. The other laboratory values would not be useful in determining the effect of the gentamicin.
After noting lengthening QRS intervals in a patient with acute kidney injury (AKI), which of the following actions should the nurse take first?
- A. Document the QRS interval.
- B. Notify the patient's health care provider.
- C. Look at the patient's current blood urea nitrogen (BUN) and creatinine levels.
- D. Check the patient's most recent blood potassium level.
Correct Answer: D
Rationale: The increasing QRS interval is suggestive of hyperkalemia, so the nurse should check the most recent potassium and then notify the patient's health care provider. The BUN and creatinine will be elevated in a patient with AKI, but they would not directly affect the electrocardiogram (ECG). Documentation of the QRS interval also is appropriate, but interventions to decrease the potassium level are needed to prevent life-threatening bradycardia.
