Pharmacology Myocardial Infarction Meds #1

Question

Which treatment(s) are considered standard medical treatment for a client admitted with chest pain associated with myocardial infarction (MI)? Select all that apply.

Answers

  1. IV morphine
    • Rationale:

      This answer is correct because Advanced Care Life Support (ACLS) and medical protocol treatment for MI in the hospital setting includes initiation intravenous (IV) morphine to reduce angina pain and to enhance oxygenation to the myocardium. Swift action by the medical personnel will hopefully decrease damage to the heart muscle and provide a more positive outcome for the client.

  2. IV nitroglycerin
    • Rationale:

      This answer is correct because Advanced Care Life Support (ACLS) and medical protocol treatment for MI in the hospital setting includes initiation of nitroglycerin to vasodilate coronary arteries and increase oxygenation to the myocardium. Swift action by the medical personnel will hopefully increase cardiac output and decrease damage to the heart muscle and provide a more positive outcome for the client.

  3. PO warfarin
    • Rationale:

      This answer is not correct because PO warfarin is not an appropriate ACLS medical protocol to treat myocardial infarction (MI). Warfarin is used in non-acute situations as an anticoagulant for management of blood clots in the body.

  4. IV digoxin
    • Rationale:

      This answer is not correct because IV digoxin is not appropriate treatment for chest pain or myocardial infarction. Digoxin is a cardiac glycoside which strengthens the contractility of the heart. It is usually used for treatment of heart failure and as an antiarrhythmic for clients with atrial fibrillation. If the provider suspects heart failure is occurring related to the MI, digoxin may be ordered.

  5. Nasal cannula O2
    • Rationale:

      This answer is correct because Advanced Care Life Support (ACLS) and medical protocol treatment for MI in the hospital setting includes initiation of oxygen therapy to increase oxygenation to the myocardium. Swift action by the medical personnel will hopefully decrease damage to the heart muscle and provide a more positive outcome for the client.

Overview

Myocardial infarction is a serious occurrence requiring swift action from the healthcare team to help provide an optimal client outcome. Knowing the standard medical protocol treatment will help expedite effective treatment.

Explanation

Learning Outcomes

Myocardial infarction (MI) occurs when there is loss of perfusion to the myocardium (heart muscle). This is usually caused by narrowing and/or blockage of coronary arteries. Advanced Care Life Support (ACLS) and medical protocol treatment for MI in the hospital setting includes initiation of nitroglycerin, intravenous (IV) morphine, and bi-nasal cannula oxygen. Swift action by the medical personnel will hopefully decrease damage to the heart muscle and provide a more positive outcome for the client.

Test Taking Tip

When answering questions that select all that apply (SATA) questions, address each question as if answering the question is a true or false question. This keeps the question from being intimidating.
