Question 1 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.
Question 2 of 5
A nurse is caring for a client who has a serum potassium level of 5.5 mEq/L. The provider prescribes polystyrene sulfonate. If this medication is effective, the nurse should expect which of the following changes on the client's ECG?
Correct Answer: C
Rationale: Effective treatment of hyperkalemia with polystyrene sulfonate reduces peaked T-waves, normalizing T-wave amplitude.
Question 3 of 5
A nurse is caring for a patient whose sodium level is 118 mEq/L. Which nursing diagnosis is a priority for this patient?
Correct Answer: B
Rationale: Severe hyponatremia (118 mEq/L) can cause cerebral edema, leading to disturbed sensory perception, a priority diagnosis.
Question 4 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.
