A patient is taking aspirin for secondary prevention of myocardial infarction and is experiencing moderate gastrointestinal upset. The nurse will contact the patient™s provider to discuss changing from aspirin to which of the following?

Correct Answer: D

Rationale: Coated aspirin refers to enteric-coated aspirin, which is a type of aspirin that has a special coating designed to help protect the stomach lining and reduce gastrointestinal upset. Unlike regular aspirin, enteric-coated aspirin is less likely to cause irritation to the stomach and therefore may be a better option for patients experiencing gastrointestinal issues. Switching to coated aspirin can help alleviate the patient's symptoms while still providing the antiplatelet benefits needed for secondary prevention of myocardial infarction. It is important for the nurse to communicate with the provider to discuss this alternative option and ensure the patient's safety and well-being.

Correct Answer: A

Rationale: When taking Digoxin, low levels of potassium can cause toxicity because digoxin competes with potassium for binding sites on the sodium-potassium pump in cardiac cells. Low potassium levels can lead to increased binding of digoxin to the pump, resulting in increased intracellular calcium levels and an increased risk of digoxin toxicity, including arrhythmias. Therefore, monitoring and maintaining adequate potassium levels are crucial in patients taking digoxin to prevent toxicity.

Correct Answer: A

Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin therapy. Green tea is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Maintaining a consistent intake of vitamin K is important for patients on warfarin in order to keep their INR (International Normalized Ratio) levels stable. It is not necessary to avoid all sources of vitamin K, but rather to keep intake consistent and moderate. Drinking large amounts of green tea, which is high in vitamin K, can potentially impact the patient's INR levels and increase the risk of bleeding or clotting issues.

Correct Answer: D

Rationale: Paliperidone, a second-generation antipsychotic, treats schizoaffective disorder's psychotic and mood symptoms via D2 and 5HT2 antagonism. Its moderate sedative effect, less than chlorpromazine's, can aid sleep onset without excessive drowsiness, fitting her insomnia complaint. Lithium stabilizes mood but doesn't sedate or address psychosis directly. Chlorpromazine, a sedating first-generation antipsychotic, risks oversedation and EPS. Haloperidol, non-sedating, controls psychosis but not mood or sleep. Ziprasidone lacks strong sedation. Paliperidone's balanced profile manages her condition holistically, improving sleep while targeting core symptoms, per evidence.
