Answer: After completing the health and physical assessment, before administering the medication, the home health nurse should perform the following actions:
Review the medication order: The nurse should verify that the prescribed dosage of digoxin (Lanoxin) is appropriate for the patient. They should double-check the order for any discrepancies or potential errors.
Assess the patient's vital signs: It is essential to assess the patient's current vital signs, including heart rate, blood pressure, and respiratory rate. These measurements provide important baseline data to evaluate the patient's response to the medication.
Assess the patient's cardiac status: Since digoxin is used for cardiac dysrhythmias, the nurse should evaluate the patient's cardiac status, including heart rhythm and any symptoms such as palpitations, shortness of breath, or chest pain. This information helps determine the appropriateness of administering digoxin and establishes a baseline for evaluating its effectiveness.
Assess the patient's electrolyte levels: Low potassium (hypokalemia) and low magnesium (hypomagnesemia) levels can increase the risk of digoxin toxicity. Therefore, it is crucial to assess the patient's electrolyte levels, particularly potassium and magnesium, through laboratory test results or previous documentation.
Review the patient's medical history and current medications: The nurse should review the patient's medical history, paying particular attention to any conditions or medications that may interact with digoxin. Conditions such as renal impairment or thyroid disorders, as well as medications like diuretics or beta-blockers, can affect digoxin's efficacy and increase the risk of toxicity.
By following these steps, the nurse ensures that the medication is appropriate for the patient, reduces the risk of adverse effects or interactions, and establishes a baseline for monitoring the patient's response to digoxin therapy.
