An adult patient at an outpatient clinic has been prescribed the antibiotic tetracycline HCI. What should the nurse include in the patient’s teaching plan?

Consume with milk or antacids to prevent gastrointestinal irritation.

Protect your skin from sunlight while on this medication.

Enhance gastrointestinal absorption by taking with orange juice.

Return to the clinic weekly for serum drug level checks.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Tetracycline should not be consumed with milk or antacids. These substances contain calcium, which can bind to tetracycline in the stomach and reduce its absorption and effectiveness.

Choice B rationale

Tetracycline can make the skin more sensitive to sunlight, increasing the risk of sunburn. Patients should be advised to protect their skin from sunlight while taking this medication.

Choice C rationale

Taking tetracycline with orange juice is not recommended. Citrus fruits and juices contain calcium, which can bind to tetracycline in the stomach and reduce its absorption and effectiveness.

Choice D rationale

Returning to the clinic weekly for serum drug level checks is not typically necessary for patients taking tetracycline. While regular follow-up appointments may be needed to monitor the patient’s response to treatment, weekly serum drug level checks are not a standard part of tetracycline therapy.

Correct Answer is A

Explanation

Choice A rationale

A. One hour after completion of the IV dose and one hour before the next administration of the medication. B. Two hours after completion of the IV dose and two hours before the next administration of the medication. C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication. D. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Correct Answer is D

Explanation

The correct answer is D. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Explanation:

Peak levels measure the highest concentration of the drug in the bloodstream and should be drawn immediately after the IV infusion is completed.
Trough levels measure the lowest concentration of the drug and should be drawn 30 minutes before the next scheduled dose. This helps ensure the drug remains within therapeutic levels and prevents toxicity.

Why the other options are incorrect:

A. One hour after completion of the IV dose and one hour before the next administration – Waiting one hour for the peak level is too long and may lead to an inaccurate measurement.
B. Two hours after completion of the IV dose and two hours before the next administration – Waiting two hours for both peak and trough levels is too late for effective monitoring.
C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration – The sample drawn mid-infusion does not represent peak levels, making this method ineffective.

Key takeaway:

Proper timing of vancomycin peak and trough monitoring ensures therapeutic drug levels while minimizing nephrotoxicity and ototoxicity.
