Question 1 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. Which of the following ECG results should indicate to the nurse that the medication has been effective?
Correct Answer: A
Rationale: Reduced T wave amplitude indicates normalized potassium levels, as hyperkalemia causes peaked T waves, and polystyrene sulfonate lowers potassium.
Question 2 of 5
A nurse is caring for a client who is using a patient-controlled analgesia (PCA) pump. The client's partner asks if she can press the button for the client while he is sleeping. Which of the following responses should the nurse make?

Rationale: A thallium scan detects heart muscle damage by identifying areas with reduced blood flow, indicating ischemia or infarction.
Question 4 of 5
A nurse is assisting with the care of a client who has hypocalcemia. For which of the following signs should the nurse monitor?

Rationale: Chvostek's sign, facial muscle twitching when tapping the facial nerve, indicates neuromuscular irritability due to hypocalcemia.
Question 5 of 5
A nurse is planning care for a client who has end-stage cirrhosis of the liver with hepatic encephalopathy. Which of the following interventions should the nurse plan to implement to decrease the client's ammonia level?
