Question 1 of 5
A nurse is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Respiratory acidosis can cause hyperkalemia, leading to widened QRS complexes due to altered cardiac conduction.
Question 2 of 5
A patient with atrial fibrillation and a serum potassium level of 3.0 mEq/L takes digoxin (Lanoxin), ASA (aspirin), KCL (potassium chloride) and warfarin (Coumadin) daily. The patient reports visual disturbances. The nurse suspects problems with which medication?
Correct Answer: A
Rationale: Digoxin toxicity, exacerbated by hypokalemia, can cause visual disturbances such as blurred vision or halos.
