The nurse is teaching a patient with stage 5 chronic kidney disease (CKD) about management of CKD. Which of the following patient statements indicate that the teaching was effective?
- A. I need to try to get more protein from dairy products.
- B. I will try to increase my intake of fruits and vegetables.
- C. I will measure my urinary output each day to help calculate the amount I can drink.
- D. I need to take the erythropoietin to boost my immune system and help prevent infection.
Correct Answer: C
Rationale: The patient with end-stage renal disease is taught to measure urine output as a means of determining an appropriate oral fluid intake. Erythropoietin is given to increase the red blood cell count and will not offer any benefit for immune function. Dairy products are restricted because of the high phosphate level. Many fruits and vegetables are high in potassium and should be restricted in the patient with CKD.

The nurse is interviewing a patient with chronic kidney disease (CKD) who brings all home medications to the clinic to be reviewed by the nurse. Which of the following medications being used by the patient indicates that patient teaching is required?
- A. Multivitamin with iron
- B. Milk of magnesia 30 mL
- C. Calcium acetate
- D. Acetaminophen 650 mg
Correct Answer: B
Rationale: Magnesium is excreted by the kidneys, and patients with CKD should not use over-the-counter products containing magnesium. The other medications are appropriate for a patient with CKD.
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.
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 with a history of benign prostatic hyperplasia (BPH) with acute urinary retention and an elevated blood urea nitrogen (BUN) and creatinine. Which of the following prescribed therapies should the nurse implement first?
- A. Obtain renal ultrasound.
- B. Insert retention catheter.
- C. Infuse normal saline at 50 mL/hour.
- D. Draw blood for complete blood count.
Correct Answer: B
Rationale: The patient's elevation in BUN and creatinine is most likely associated with hydronephrosis caused by the acute urinary retention, so the insertion of a retention catheter is the first action to prevent ongoing postrenal failure for this patient. The other actions also are appropriate but should be implemented after the retention catheter.
Which of the following parameters is most important for the nurse to consider when titrating the IV fluid infusion rate immediately after a patient has had kidney transplantation?
- A. Heart rate
- B. Blood urea nitrogen (BUN) level
- C. Urine output
- D. Creatinine clearance
Correct Answer: C
Rationale: Fluid volume is replaced based on urine output after transplant because the urine output can be as high as a litre an hour. The other data will be monitored but are not the most important determinants of fluid infusion rate.
