A patient is receiving an IV infusion of a thrombolytic drug during treatment for an acute MI. The nurse notices that there is a slight amount of bleeding from the antecubital area where venous lab work was drawn. What will the nurse do first?

Correct Answer: B

Rationale: In this situation, the nurse's first priority should be to apply pressure to the site with a gauze pad. Bleeding from the antecubital area where venous lab work was drawn can be due to the effect of the thrombolytic drug, particularly in a patient who is already at risk for bleeding due to the acute MI. Applying pressure to the site will help control the bleeding and prevent any further complications. Once the bleeding is controlled, the nurse should monitor the site closely for any signs of increased bleeding or other complications. Slowing the rate of infusion or stopping the infusion of the thrombolytic drug may be considered depending on the severity of the bleeding and the patient's overall condition, but the immediate response should be to apply pressure to the site.

Correct Answer: C

Rationale: Digoxin is a medication commonly used to treat heart failure and certain types of irregular heartbeats. Its therapeutic effect includes increasing cardiac output, which helps improve the function of the heart. Digoxin also has the ability to slow down the heart rate, making it particularly beneficial for patients with conditions like atrial fibrillation or atrial flutter. Therefore, among the options provided, Digoxin is the drug that has a therapeutic effect of increasing cardiac output and slowing heart rate.

Correct Answer: C

Rationale: Amiodarone is the drug of choice for treating severe ventricular dysrhythmias, such as those seen in patients with acute myocardial infarction. It is effective in treating both ventricular tachycardia and ventricular fibrillation. Amiodarone works by prolonging the action potential duration and refractory period in cardiac tissues, thereby helping to stabilize the heart's electrical activity. Diltiazem and Verapamil are calcium channel blockers that are not typically used for treating ventricular dysrhythmias. Adenosine is primarily used for treating supraventricular tachycardias.

Correct Answer: C

Rationale: Acetaminophen is a commonly used analgesic and antipyretic, but excessive doses can lead to severe liver damage. The maximum recommended daily dose for adults is 4 grams (4000 mg). Exceeding this limit increases the risk of hepatotoxicity, which can be life-threatening. Nurses should educate patients about the importance of adhering to the recommended dosage and checking the acetaminophen content in over-the-counter medications to avoid accidental overdose. This teaching is critical for patient safety and preventing adverse outcomes.

Correct Answer: D

Rationale: Phenylbutazone is a nonsteroidal anti-inflammatory drug (NSAID) known for its potential to cause bone marrow depression. Bone marrow depression is a serious side effect that can lead to decreased production of blood cells, including white blood cells, red blood cells, and platelets. This can result in an increased risk of infections, anemia, and bleeding disorders. Therefore, phenylbutazone should be used cautiously and under close monitoring to avoid this complication. Aspirin, Colchicine, Ibuprofen, and Acetaminophen are not typically associated with causing bone marrow depression as a side effect.
