A client enters the emergency department with suspected exposure to anthrax. The physician confirms this suspicion and orders the client an antibiotic. Which medication would the nurse expect the physician to order?
Doxycycline
Penicillin
Oxytetracycline (Terramycin)
Ciprofloxacin
The Correct Answer is D
A. Doxycycline:
Doxycycline is a tetracycline antibiotic that is effective against anthrax. It is commonly used for post-exposure prophylaxis and treatment of anthrax infections.
B. Penicillin:
Penicillin is not typically the first-line antibiotic for treating anthrax. While some strains of Bacillus anthracis may be susceptible to penicillin, other antibiotics like doxycycline or ciprofloxacin are preferred due to their broader spectrum of activity and better penetration into tissues.
C. Oxytetracycline (Terramycin):
Oxytetracycline is another tetracycline antibiotic similar to doxycycline. Like doxycycline, oxytetracycline is effective against anthrax and can be used for post-exposure prophylaxis and treatment of anthrax infections.
D. Ciprofloxacin:
Ciprofloxacin is a fluoroquinolone antibiotic that is effective against anthrax. It is commonly used as an alternative to doxycycline for post-exposure prophylaxis and treatment of anthrax infections, particularly for individuals who cannot tolerate tetracyclines.

Correct Answer is B
Explanation
A. Never take with prescription medications:
This statement is not accurate. Many herbal products can interact with prescription medications, potentially leading to adverse effects or reduced efficacy. However, avoiding taking herbal products with prescription medications altogether may not be practical or necessary in all cases. Instead, it's essential to assess for potential interactions and consult with healthcare professionals.
B. Use only one herbal preparation at a time:
This is the correct approach. Using only one herbal preparation at a time allows for better identification of any allergic reactions or adverse effects. If multiple herbal products are taken simultaneously, it can be challenging to determine which product is causing a particular reaction. Starting with one product also simplifies monitoring for efficacy and safety.
C. Take less than the recommended dose initially:
While starting with a lower dose initially may be a prudent approach for some individuals, it is not necessarily the best way to identify allergic or adverse reactions. Taking less than the recommended dose may not provide a full assessment of the product's effects and may not adequately identify potential adverse reactions.
D. Check with a reputable pharmacist:
Consulting with a reputable pharmacist is essential for obtaining information about herbal products, including potential interactions, side effects, and recommended dosages. While a pharmacist can provide valuable guidance, they may not be present during the initial use of the herbal product to monitor for adverse reactions directly.
Correct Answer is A
Explanation
A. Refers to an infection that is resistant to conventional antibiotics:
This statement is partially correct. Acquired resistance does indeed refer to bacteria becoming resistant to antibiotics, but it is not specific to conventional antibiotics. Bacteria can develop resistance to various types of antibiotics, including conventional antibiotics and newer antimicrobial agents.
B. Superinfection that has significant antifungal resistance:
This statement is incorrect. Acquired resistance specifically pertains to bacteria and their ability to resist antibiotics. It does not involve antifungal resistance or superinfections.
C. Refers to a term used for antibiotic coverage:
This statement is incorrect. Acquired resistance is not a term used to describe antibiotic coverage. It describes the phenomenon of bacteria becoming resistant to antibiotics.
D. There is no such phenomenon of acquired resistance:
This statement is incorrect. Acquired resistance is a well-documented phenomenon in microbiology and is a significant challenge in the treatment of bacterial infections. Ignoring or denying the existence of acquired resistance would overlook a critical aspect of antibiotic stewardship and management of bacterial infections.
