Ati lpn med surg proctored exam (blood immune test)
A patient is scheduled to take tetracycline and aluminum hydroxide (Amphojel) at the same time. Which time accurately describes when the nurse will administer the medications to achieve the optimal effects?
Explanation & Rationale
A. Both medications together: Antacids (Amphojel) contain metal cations that bind to tetracycline, preventing its absorption. B. Tetracycline 1 hour before Amphojel: To prevent a drug-drug interaction, tetracycline should be taken on an empty stomach at least 1 hour before or 2 hours after antacids. C. Amphojel 30 minutes before tetracycline: The antacid will still be in the stomach and will interfere with the antibiotic's absorption. D. Tetracycline with orange juice: While Vitamin C helps iron absorption, it does not solve the interaction issue with aluminum hydroxide.
