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. If this medication is effective, the nurse should expect which of the following changes on the client's ECG?
Correct Answer: C
Rationale: This is correct because a reduction of T-wave amplitude is a sign of hyperkalemia reversal. Polystyrene sulfonate lowers serum potassium, reversing ECG changes like peaked T waves.
Question 2 of 5
A nurse is caring for a client who has hypertension and develops epistaxis. Which of the following actions should the nurse take?
Correct Answer: A,C,E
Rationale: Correct actions include placing ice to cause vasoconstriction, moving to high-Fowler's to lower head/neck blood pressure, and applying pressure to compress the bleeding site.
Question 3 of 5
A nurse is observing the closed chest drainage system of a client who is 24 hr post thoracotomy. The nurse notes slow, steady bubbling in the suction control chamber. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: Slow, steady bubbling in the suction control chamber indicates proper suction, so the nurse should continue monitoring.
Question 4 of 5
A nurse is reviewing the laboratory data of a client following a hemodialysis treatment. The nurse should expect to find a decrease in which of the following laboratory values?
Correct Answer: B
Rationale: Potassium levels decrease after hemodialysis, which removes excess potassium from the blood.
Question 5 of 5
A nurse is caring for a client who has a cardiopulmonary arrest. The nurse anticipates the emergency response team will administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?
Correct Answer: D
Rationale: This is correct because atropine is used for symptomatic bradycardia, increasing heart rate by blocking parasympathetic activity.
