A nurse is teaching a client who has a fungal infection about fluconazole.
Which of the following statements by the client indicates an understanding of the teaching?

Amoxicillin-clavulanate is an antibiotic that belongs to the penicillin group and is effective against Escherichia coli, the most common cause of urinary tract infections (UTIs).It works by inhibiting the bacterial cell wall synthesis and preventing the bacteria from producing an enzyme that makes them resistant to penicillin.

Choice B is wrong becauseVancomycin is wrong because it is an antibiotic that is used to treat serious infections caused by gram-positive bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA).It is not effective against gram-negative bacteria, such as Escherichia coli.

Choice C is wrong becausePenicillin G is wrong because it is an antibiotic that is effective against some gram-positive bacteria, such as Streptococcus and Neisseria.However, many strains of Escherichia coli are resistant to penicillin G and can produce an enzyme called beta-lactamase that breaks down the antibiotic.

Choice D is wrong becauseAcyclovir is wrong because it is an antiviral drug that is used to treat infections caused by herpes simplex virus (HSV) and varicella-zoster virus (VZV).It has no activity against bacteria, such as Escherichia coli.

This is because penicillin G is a beta-lactam antibiotic that can cause severe allergic reactions in some people, such as anaphylaxis, rash, or angioedema. Therefore, the nurse should always check for any history of allergies before administering penicillin G or any other beta-lactam antibiotic.

Choice A is wrong because checking the client’s temperature is not a priority action before giving penicillin G.Although fever is a common sign of meningitis, it does not affect the administration of penicillin

Choice B is wrong because assessing the client’s level of consciousness is not a priority action before giving penicillin G.Although altered mental status is a common sign of meningitis, it does not affect the administration of penicillin

Choice D is wrong because obtaining a blood sample for culture and sensitivity is not a priority action before giving penicillin G.Although culture and sensitivity tests are important to identify the causative organism and the appropriate antibiotic, they should not delay the initiation of empiric therapy for meningitis.Penicillin G is effective against Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in adults.
