The patient is complaining of a viselike pain in the chest and has been diagnosed with a myocardial infarction. The nurse anticipates that he may be given which of the following medications? (Select all that apply.)
A.
An ACE inhibitor
B.
Thrombolytics
C.
Aspirin
D.
A potassium-sparing diuretic
E.
A beta blocker
The correct answer and Explanation is :
For a patient diagnosed with a myocardial infarction (MI), the nurse should anticipate the administration of the following medications:
B. Thrombolytics
C. Aspirin
E. A beta blocker
Explanation:
- Thrombolytics: Thrombolytic agents are crucial in the acute management of myocardial infarction, especially when administered within the first few hours of symptom onset. These medications work by dissolving the blood clot that is obstructing the coronary artery, thereby restoring blood flow to the heart muscle. Common thrombolytics include alteplase, reteplase, and tenecteplase.
- Aspirin: Aspirin is a cornerstone in the treatment of myocardial infarction. It acts as an antiplatelet agent, reducing the ability of platelets to clump together and form additional clots. This helps in minimizing further blockage in the coronary arteries and reduces the risk of subsequent cardiovascular events.
- Beta Blockers: Beta blockers are used to reduce the workload on the heart by decreasing heart rate, blood pressure, and the heart’s oxygen demand. This can help limit the size of the infarction and improve outcomes. Examples include metoprolol and atenolol. They are typically administered after the initial acute phase and may be continued long-term to prevent further complications.
Not typically used in acute MI management:
- An ACE inhibitor (A): While ACE inhibitors are beneficial for patients with heart failure, left ventricular dysfunction, or high blood pressure, they are generally introduced in the post-acute phase of myocardial infarction rather than immediately during the acute treatment.
- A potassium-sparing diuretic (D): Potassium-sparing diuretics are not a first-line treatment in acute myocardial infarction. They are used in cases of heart failure or to manage fluid balance but are not typically administered during the initial MI treatment phase.
In summary, thrombolytics, aspirin, and beta blockers are integral to the management of myocardial infarction, addressing clot dissolution, platelet aggregation, and myocardial stress reduction, respectively.
