Before administering cefazolin (Ancef), the nurse checks for a previous allergic reaction to:

Sulfonamides

Macrolides

Yeast

Penicillin

Answer and Explanation

The Correct Answer is D

A. Sulfonamides:

Sulfonamides are a class of antibiotics that are structurally distinct from cephalosporins like cefazolin. Allergic reactions to sulfonamides do not necessarily indicate a risk of allergy to cefazolin. However, it's still important to assess for any previous allergic reactions to medications, including sulfonamides, as individuals can have multiple medication allergies.

B. Macrolides:

Macrolides are another class of antibiotics that are structurally different from cephalosporins. Allergic reactions to macrolides do not directly indicate an allergy to cefazolin. However, as with sulfonamides, it's crucial to assess for any history of allergic reactions to medications, including macrolides.

C. Yeast:

Yeast is not a class of antibiotics but rather a type of fungus. Allergic reactions to yeast are unrelated to cephalosporin antibiotics like cefazolin. Therefore, a history of allergic reactions to yeast does not suggest an allergy to cefazolin.

D. Penicillin:

This is the correct choice. Penicillins and cephalosporins share a similar beta-lactam ring structure. Individuals who have had allergic reactions to penicillin may have an increased risk of cross-reactivity with cephalosporins, including cefazolin. Therefore, it's crucial to assess for any previous allergic reactions to penicillin before administering cefazolin to avoid potential allergic reactions or adverse effects.

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.

A. Penicillins B. Fluoroquinolones C. Aminoglycosides D. Sulfonamides

Correct Answer is B

Explanation

A. Penicillins:

Penicillins are a class of antibiotics commonly used to treat various bacterial infections. While they are generally well-tolerated and have a low incidence of adverse effects, they are not typically associated with cartilage toxicity or tendon rupture, including the Achilles tendon.

B. Fluoroquinolones:

Fluoroquinolones are broad-spectrum antibiotics known for their effectiveness against a wide range of bacteria. However, they are associated with several significant adverse effects, including cartilage toxicity and tendon rupture. These adverse effects, particularly tendon rupture, are most commonly observed in weight-bearing tendons such as the Achilles tendon. Fluoroquinolones should be used cautiously, especially in populations at higher risk for tendon injuries.

C. Aminoglycosides:

Aminoglycosides are another class of antibiotics used to treat severe bacterial infections. While they have their own set of potential adverse effects, such as nephrotoxicity and ototoxicity, they are not associated with cartilage toxicity or tendon rupture.

D. Sulfonamides:

Sulfonamides are antibiotics that inhibit bacterial growth by interfering with the synthesis of folate. While they can cause various adverse effects, including skin reactions and hematologic abnormalities, they are not associated with cartilage toxicity or tendon rupture.
