A nurse is caring for a client.

Exhibits

After reviewing the information in the client's medical record, which of the following provider prescriptions should the nurse anticipate?

Complete the following sentence by using the list of options.

The nurse should anticipate a provider prescription for

___

as evidenced by the client's

___

.

A. Macrolides:
Macrolides, such as azithromycin and erythromycin, are not structurally related to penicillin and are generally considered safe alternatives for individuals with penicillin allergies. These antibiotics are commonly prescribed for conditions like strep throat when the patient cannot tolerate penicillin. Macrolides do not have a significant risk of cross-sensitivity with penicillin.

B. Cephalosporins:
Cephalosporins, a class of antibiotics such as cefazolin, ceftriaxone, and cephalexin, are structurally similar to penicillin and carry a risk of cross-sensitivity in individuals who are allergic to penicillin. Although not all patients with a penicillin allergy will react to cephalosporins, there is a higher likelihood of an allergic reaction due to the similar beta-lactam ring structure. Therefore, cephalosporins should generally be avoided in patients with a known penicillin allergy unless there is no alternative treatment and the benefits outweigh the risks.

C. Tetracyclines:
Tetracyclines, including drugs like doxycycline and tetracycline, are a separate class of antibiotics that are not structurally related to penicillin. As such, tetracyclines do not present a significant risk of cross-sensitivity with penicillin. These antibiotics are often used as alternatives for patients who cannot tolerate penicillin or cephalosporins.

D. Sulfonamides:
Sulfonamides (e.g., trimethoprim-sulfamethoxazole) are another distinct class of antibiotics that do not have cross-sensitivity with penicillin. They are safe for patients with a penicillin allergy and are not related to the beta-lactam structure found in penicillin and cephalosporins. Sulfonamides are commonly used for various infections but would be chosen based on the specific pathogen and resistance patterns, rather than as a direct alternative for penicillin.

A) Increase in the client's liver panel:
Fluconazole (Diflucan) is an antifungal medication that is metabolized in the liver, and one of the potential side effects of this drug is liver toxicity. This can manifest as an increase in liver enzymes (such as AST, ALT, or alkaline phosphatase) seen in the liver panel. It is important for the nurse to monitor the client’s liver function, especially if the patient has pre-existing liver conditions. If there are signs of liver toxicity, such as jaundice, abdominal pain, or elevated liver enzymes, the healthcare provider should be notified and the medication may need to be adjusted or discontinued.

B) Increase in the client's creatinine clearance:
Fluconazole is primarily eliminated through the kidneys, but it does not typically cause an increase in creatinine clearance. In fact, in patients with renal impairment, fluconazole can lead to an increase in serum creatinine levels due to reduced renal clearance of the drug. Therefore, a decrease (rather than an increase) in creatinine clearance is a more common concern, and renal function should be monitored during treatment.

C) Change of color to the client's secretions:
Fluconazole is not known to cause a change in the color of secretions (such as urine, saliva, or sweat). This side effect is more commonly associated with certain medications like rifampin (which can turn urine or sweat orange). However, fluconazole’s side effects are generally related to liver and renal function, as well as gastrointestinal disturbances, not to changes in secretions.

D) Red Man syndrome:
Red Man syndrome is a reaction typically associated with vancomycin, an antibiotic used for Gram-positive infections, especially when administered too rapidly via IV. It is characterized by flushing, rash, and hypotension, and is not a side effect of fluconazole. Fluconazole does not cause this type of infusion-related reaction, so this is not a concern with fluconazole therapy.
