A client exposed to anthrax has presented to the healthcare setting. Which of the following medications below is the treatment for this biological exposure?
Amoxicillin/clavulanate (Augmentin)
Nystatin (Mycostatin)
Ciprofloxacin (Cipro)
Tamoxifen
The Correct Answer is C
A. Amoxicillin/clavulanate (Augmentin): Amoxicillin/clavulanate is a broad-spectrum antibiotic but not the preferred choice for anthrax exposure.
B. Nystatin (Mycostatin): Nystatin is an antifungal medication used for treating fungal infections, such as oral thrush or cutaneous candidiasis. It is not effective against anthrax, which is a bacterial infection.
C. Ciprofloxacin (Cipro): Ciprofloxacin, a fluoroquinolone, is the recommended first-line antibiotic for treating anthrax exposure due to its efficacy against Bacillus anthracis, the bacteria causing anthrax.
D. Tamoxifen: Tamoxifen is a selective estrogen receptor modulator (SERM) used primarily in the treatment of breast cancer. It has no role in treating bacterial infections like anthrax.

Correct Answer is D
Explanation
A. Regular sun exposure is needed to maximize drug efficacy: This is incorrect; in fact, doxycycline can cause photosensitivity, and sun exposure should be minimized.
B. Avoid water while taking this medication: Water should be taken with doxycycline to help prevent esophageal irritation.
C. Take this medication with antacids to relieve gastrointestinal symptoms: Antacids can also interfere with doxycycline absorption, so they should be avoided.
D. Avoid dairy products when taking this medication: Dairy products can bind to doxycycline and reduce its absorption in the gastrointestinal tract, which decreases its effectiveness. The client should avoid dairy when taking the medication.
