## Question

Complete the administration teaching for oral omadacycline.

Before oral omadacycline, fast for at least ::선택::1 hour2 hours4 hours8 hours. After the dose, consume only water for ::선택::1 hour2 hours4 hours6 hours and avoid dairy, antacids, or multivitamins for ::선택::1 hour2 hours3 hours4 hours.

## Explanation

Oral omadacycline is taken after at least 4 hours of fasting. After the dose, only water is allowed for 2 hours, and dairy, antacids, or multivitamins are avoided for 4 hours.

## In-depth explanation

Quick answer
Protect omadacycline absorption from food and polyvalent cations.

Why this is correct
Food and products containing calcium, magnesium, aluminum, bismuth, or iron can reduce tetracycline-class absorption and undermine the prescribed exposure.

Easy analogy or mental picture
Use a closed medication-safety loop: identify the exposure, connect the new findings, interrupt further harm, support physiology, and verify the response over time.

Memory hook
Exposure, interaction, toxicity pattern, immediate action, serial reassessment.

NCLEX decision rule
Choose the action that reduces the most immediate medication-related risk while preserving monitoring and escalation.

Why the other choices are wrong
Options that continue the exposure, treat only one symptom, or delay reassessment leave the toxic process active.References
