ATI Med Surg Exam 2 Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has acute kidney injury (AKI). Which of the following arterial blood gas (ABG) values would the nurse expect this client to have?
Correct Answer: D
Rationale: Metabolic acidosis (pH 7.26, HCO3 14) is expected in AKI due to acid accumulation. Other sets indicate respiratory or metabolic alkalosis.
Question 2 of 5
A nurse is caring for a client who has impaired renal function. For which of the following findings should the nurse notify the provider?
Correct Answer: B
Rationale: Oliguria (175 mL/8 hr) suggests worsening renal function, requiring notification. Strong odor, normal output, and cloudy urine are less urgent.
Question 3 of 5
A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.5 tablets
Rationale: 0.125 mg ÷0.25 mg/tablet = 0.5 tablets per dose.
Question 4 of 5
A nurse is caring for a male client who reports nausea and vomiting and is receiving IV fluid therapy. His blood urea nitrogen (BUN) is 32 mg/dL, creatinine is 1.1 mg/dL, and hematocrit is 50%. Which of the following nursing interventions is appropriate?
Correct Answer: C
Rationale: Elevated BUN suggests dehydration; evaluating urine amount and specific gravity assesses hydration status. Fluid reduction, cultures, or routine care are inappropriate.
Question 5 of 5
A nurse is caring for a client who has chronic renal disease and is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?
Correct Answer: B
Rationale: Epoetin alfa increases red blood cell production, raising hematocrit. ESR, platelets, and leukocytes are unaffected.
