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?
Attach the leads for a 12-lead ECG.
Initiate oxygen therapy.
Insert the IV catheter.
Obtain a blood sample.
The Correct Answer is B
The correct answer is: B. Initiate oxygen therapy.
Choice A reason:
Attaching the leads for a 12-lead ECG is crucial for diagnosing a myocardial infarction. However, it is not the first priority. Ensuring the patient receives adequate oxygen is more critical to prevent further myocardial damage. The ECG can be performed immediately after oxygen therapy is initiated to confirm the diagnosis and guide further treatment.
Choice B reason:
Initiating oxygen therapy is the first priority because it ensures that the heart muscle receives adequate oxygen, which is essential to prevent further damage during a myocardial infarction. Oxygen therapy helps to maintain tissue oxygenation and can reduce the extent of myocardial injury. This immediate intervention is vital to stabilize the patient and improve outcomes.
Choice C reason:
Inserting the IV catheter is important for administering medications and fluids. However, it is not the first step. Oxygen therapy takes precedence to ensure the heart and other vital organs receive sufficient oxygen. Once oxygen is administered, IV access can be established to facilitate further treatment.
Choice D reason:
Obtaining a blood sample is necessary for confirming the diagnosis and assessing cardiac markers. However, it is not the immediate priority. Ensuring the patient is oxygenated is more urgent to prevent further myocardial damage. Blood samples can be drawn after oxygen therapy is initiated.

Correct Answer is ["A","C","E"]
Explanation
Choice A Reason: This is correct because placing ice to the bridge of the client’s nose can cause vasoconstriction and reduce blood flow to the nasal mucosa.
Choice B Reason: This is incorrect because tilting the client's head backward can cause blood to drain into the throat and increase the risk of aspiration, nausea, and vomiting.
Choice C Reason: This is correct because moving the client into high-Fowler position can lower the blood pressure in the head and neck and decrease bleeding.
Choice D reason Reason This is incorrect because instructing the client to blow his nose can dislodge any clots that have formed and worsen bleeding.
Choice E Reason: This is correct because applying pressure to the nares can compress the bleeding site and promote clotting.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect. The balloons should not be deflated without a physician's order, as this can cause rebleeding or aspiration.
Choice B Reason: This is incorrect. The head of the bed should be elevated to 30 to 45 degrees to reduce pressure on the balloons and prevent gastric reflux.
Choice C Reason: This is correct. The nurse should monitor the client closely for signs of complications, such as airway obstruction, aspiration, or balloon rupture. The nurse should also keep scissors at the bedside to cut the tube and release the balloons in case of an emergency.
Choice D Reason: This is incorrect. The tube should not be suctioned, as this can damage the mucosa and cause bleeding. The nurse should only aspirate gastric contents through the gastric lumen to decompress the stomach.
