Question 1 of 5
A nurse in the emergency room is caring for a client who presents with manifestations that indicate a myocardial infarction. Which of the following prescriptions should the nurse take first?
Correct Answer: B

Question 2 of 5
A nurse is triaging victims of a multiple motor-vehicle crash. The nurse assesses a client trapped under a car who is apneic and has a weak pulse at 120/min. After repositioning his upper airway, the client remains apneic. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: In mass casualty triage, an apneic client who does not resume breathing after airway repositioning is tagged black, indicating non-salvageable status.
Question 3 of 5
A nurse in an emergency department is assessing a client who was bitten on the left leg by a poisonous snake. The client has placed elastic bandages snugly above and below the bite marks and is in no apparent distress. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Removing elastic bandages prevents impaired blood flow and tissue damage, while elevating the leg reduces venom absorption.
Question 4 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.
