Chapter 49 Questions
Question 1 of 5
Which of the following assessments should the nurse complete before administering sodium polystyrene sulphonate to a patient with hyperkalemia?
Correct Answer: C
Rationale: Sodium polystyrene sulphonate should not be given to a patient who does not have normal bowel function because bowel necrosis can occur. The BUN and creatinine, blood glucose, and LOC would not affect the nurse's decision to give the medication.
Question 2 of 5
The nurse is caring for a patient who has had an insertion of an arteriovenous graft (AVG) in the right forearm and has symptoms of pain and coldness of the right fingers. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The patient's complaints suggest the development of distal ischemia (steal syndrome) and may require revision of the AVG. Elevation of the arm above the heart will decrease perfusion. Pain and coolness are not normal after AVG insertion. Aspirin therapy is not used to maintain grafts.
Question 3 of 5
Which of the following actions by a patient who is using peritoneal dialysis (PD) indicates that the nurse should provide more teaching about PD?
Correct Answer: D
Rationale: Patients are taught to avoid insertion site infection and should be encouraged to take showers rather than baths to avoid infections at the catheter insertion side. The other patient actions indicate good understanding of peritoneal dialysis.
Question 4 of 5
The nurse is caring for a patient with chronic kidney disease (CKD) who is prescribed calcium carbonate. Which of the following parameters should the nurse assess in order to determine the effectiveness of the treatment?
Correct Answer: B
Rationale: Calcium carbonate is prescribed to bind phosphorus and prevent mineral and bone disease in patients with CKD. The other data will not be helpful in evaluating the effectiveness of calcium carbonate.
Question 5 of 5
Which of the following information is most useful to the nurse in evaluating improvement in kidney function for a patient who is hospitalized with acute kidney injury (AKI)?
Correct Answer: D
Rationale: GFR is the preferred method for evaluating kidney function. BUN levels can fluctuate based on factors such as fluid volume status. Urine output can be normal or high in patients with AKI and does not accurately reflect kidney function. Creatinine alone is not an accurate reflection of renal function.
