ATI Med Surg Exam 2 Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has chronic kidney disease (CKD) and reports heartburn. The provider prescribes aluminum hydroxide. The client asks, 'Why can't I just take the antacid magaldrate that my husband has at home?' The nurse explains to the client that aluminum hydroxide is the preferred antacid because it lowers which of the following?
Correct Answer: B
Rationale: Aluminum hydroxide binds phosphate, lowering serum phosphorus in CKD. It does not primarily affect calcium, potassium, or magnesium.
Question 2 of 5
A nurse is teaching a client who has urolithiasis (renal calculi). The nurse should explain that which of the following conditions can increase the risk for renal calculi?
Correct Answer: C
Rationale: Dehydration concentrates urine, promoting stone formation. Iron deficiency, proteinuria, and obesity are less directly linked.
Question 3 of 5
A nurse is reviewing the laboratory test results from a client who has prerenal acute kidney injury (AKI). Which of the following electrolyte imbalances should the nurse expect?
Correct Answer: D
Rationale: Hyperkalemia occurs in prerenal AKI due to reduced potassium excretion from decreased renal perfusion. Hypernatremia, hypophosphatemia, and hypercalcemia are not typical.
Question 4 of 5
A nurse is teaching a client who has chronic kidney disease about the process of continuous ambulatory peritoneal dialysis (CAPD). Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: CAPD allows fewer dietary/fluid restrictions than hemodialysis due to continuous waste removal. It's not specific to surgery, rigid schedules, or dialyzers.
Question 5 of 5
A nurse is reviewing the arterial blood gas values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
Correct Answer: C
Rationale: Metabolic acidosis (pH 7.25, HCO3- 19) is expected in CKD due to acid accumulation. Other sets indicate respiratory or metabolic alkalosis.
