Final answer:
The statement indicating a need for further teaching is that the client can prevent stomach upset by taking digoxin with an antacid. Antacids can affect the absorption of digoxin, and patients should be advised about the proper way to take their medication to ensure its effectiveness.
Step-by-step explanation:
The subject of this question is Medicine, specifically pharmacology and patient education related to the medication Digitek (digoxin), which is used to treat congestive heart failure. The correct answer to the question, which asks which statement indicates the client needs further teaching is: "I can prevent stomach upset by taking the medication with an antacid." This statement is incorrect because antacids can interfere with the absorption of digoxin, potentially leading to subtherapeutic levels and reduced efficacy of the medication. Patients should be advised to take digoxin on an empty stomach and avoid taking antacids within 2 hours of their digoxin dose.
Patients need to take digoxin at the same time each day due to its pharmacokinetics; eating foods containing fiber may help prevent drug toxicity by preventing constipation, which can affect medication absorption; and visual changes can be a sign of digoxin toxicity, thus reporting them to a doctor is appropriate.
