The nurse is providing discharge teaching for a patient who will be taking oral linezolid (Zyvox) to treat a complicated skin infection caused by vancomycin-resistant enterococci (VRE).
Which statement by the patient indicates a need for further teaching?
“I will report any changes in my vision to my doctor.”
“I will avoid eating foods that contain tyramine.”
“I will take this medication on an empty stomach.”
“I will continue to take this medication until I feel better."
The Correct Answer is D
This statement indicates a need for further teaching because linezolid should be taken for the full prescribed course of treatment, even if the symptoms improve or resolve. Stopping the medication too soon can lead to bacterial resistance or recurrence of the infection.
Choice A is wrong because it is a correct statement. Linezolid can cause optic neuropathy or vision changes, so patients should report any changes in their vision to their doctor.
Choice B is wrong because it is a correct statement.
Linezolid can interact with foods that contain tyramine, such as cheese and red wine, and cause a hypertensive crisis. Patients should avoid eating foods that contain tyramine while taking linezolid and for two weeks after stopping the medication.
Choice C is wrong because it is a correct statement. Linezolid can be taken with or without food, but taking it on an empty stomach may help with absorption and effectiveness.

Explanation
These are the antimalarial drugs that are recommended for prophylaxis by the CDC and other sources.
They are effective against the malaria parasites that are resistant to chloroquine and primaquine, which are the other two options.
Choice A is wrong because chloroquine is not effective in areas where chloroquine resistance is present, which is most of the malaria-endemic regions.
Choice B is wrong because primaquine is not used for prophylaxis, but for radical cure of vivax and ovale malaria.It also requires a test for glucose-6-phosphate dehydrogenase (G6PD) deficiency before use, as it can cause hemolysis in people with this condition.
Choice C is correct because mefloquine is a suppressive prophylactic that can be used in areas with chloroquine resistance.
