A client is diagnosed with influenza A and is prescribed oseltamivir.
Which of the following statements by the client indicates a need for further education?

This statement indicates a need for further education because oseltamivir does not prevent the transmission of influenza virus to others.Oseltamivir is an antiviral drug that can shorten the duration of symptoms, reduce the risk of complications, and work best if started within 48 hours of symptom onset. However, it does not eliminate the virus from the body or provide immunity against future infections.Therefore, the client should still practice good hygiene and avoid contact with others who are at high risk of influenza complications.

Choice A is wrong because oseltamivir can shorten the duration of symptoms by about one day if taken within 48 hours of symptom onset.

Choice C is wrong because oseltamivir works best if started within 48 hours of symptom onset, as it inhibits the viral replication and reduces the viral load.

Choice D is wrong because oseltamivir may cause nausea and vomiting as side effects in some people, especially if taken without food.These side effects are usually mild and transient and can be minimized by taking the medication with food or milk.

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.
