The nurse is caring for a client following a myocardial infarction (MI) and prescribed asprin 325mg PO daily. Which of following effects of this medication would this client benefit from following a MI?

A.

Inhibits platelet aggregation

B.

Anti-inflammatory properties

C.

Antiemetic

D.

Anti-pyretic

Answer and Explanation

The Correct Answer is A


A) Inhibits platelet aggregation: The primary benefit of aspirin following a myocardial infarction (MI) is its ability to inhibit platelet aggregation. By preventing platelets from clumping together, aspirin reduces the risk of further clot formation, which is critical in preventing additional cardiac events and improving overall cardiovascular outcomes.

 

B) Anti-inflammatory properties: While aspirin does have anti-inflammatory effects, this is not the primary reason it is prescribed after an MI. The focus in the post-MI setting is on its role in preventing clot formation rather than addressing inflammation.

 

C) Antiemetic: Aspirin is not an antiemetic and does not alleviate nausea or vomiting. Clients experiencing gastrointestinal issues or nausea would require different medications for those symptoms.

D) Anti-pyretic: Although aspirin can reduce fever, this effect is not the primary concern in the post-MI setting. The immediate goal is to improve heart health and prevent further thrombotic events, making platelet inhibition the most relevant benefit.

Correct Answer is A

Explanation

A) Hypokalemia: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Since digoxin competes with potassium for binding at the sodium-potassium ATPase site in the heart, low potassium levels can lead to increased digoxin effects and toxicity. Therefore, it is crucial to monitor potassium levels and correct any deficiencies before administering digoxin.

B) Hyperkalemia: While hyperkalemia is a serious concern and can also affect digoxin therapy, it usually results in decreased effectiveness of digoxin rather than increasing toxicity. Elevated potassium levels can diminish the drug's positive inotropic effect.

C) Hypocalcemia: Although calcium levels can influence cardiac function, hypocalcemia is not directly related to digoxin toxicity. Monitoring calcium is important for overall cardiac health, but it is not the primary focus when assessing the risk for digoxin toxicity.

D) Hypernatremia: Elevated sodium levels do not have a direct impact on the efficacy or toxicity of digoxin. While sodium levels are essential to monitor for overall health, they are not critical in the context of digoxin administration and toxicity risk.
