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?

Cefazolin can cause serious or life-threatening allergic reactions in some patients, especially those with a history of penicillin allergy.The most common allergic reactions to cefazolin are immediate reactions, such as anaphylaxis, urticaria, bronchospasm, and angioedema.These reactions usually occur within one hour of the drug administration and may involve symptoms such as rash, itching, swelling, difficulty breathing, low blood pressure, and shock.Immediate reactions are mediated by immunoglobulin E (IgE) antibodies that bind to the drug and trigger the release of inflammatory mediators from mast cells and basophils.

Choice D is wrong because Stevens-Johnson syndrome is not a typical allergic reaction to cefazolin.

Stevens-Johnson syndrome is a rare and severe skin reaction that can be caused by various drugs, infections, or autoimmune diseases.

It involves blistering and peeling of the skin and mucous membranes, fever, malaise, and eye inflammation.

Stevens-Johnson syndrome is not mediated by IgE antibodies, but by other immune mechanisms that damage the skin cells.

Cefazolin is not known to cause Stevens-Johnson syndrome, although other cephalosporins have been reported to do so in rare cases.

The client should avoid sexual intercourse until treatment is completed.This is because trichomoniasis is a sexually transmitted infection that can be passed between partners during penile-vaginal sex or through transmission of infected vaginal fluids or fomites among women who have sex with women. Therefore, abstaining from sex until both partners are cured can prevent reinfection and transmission.

Choice A is wrong because taking the medication with an antacid can reduce its absorption and effectiveness.Tinidazole should be taken with food to minimize gastrointestinal side effects.

Choice B is wrong because drinking plenty of fluids to prevent crystalluria is not relevant for tinidazole.

Crystalluria is a condition where crystals form in the urine, which can cause kidney stones or damage.This is a potential complication of some antibiotics, such as sulfonamides, but not tinidazole.

Choice D is wrong because chewing the tablets thoroughly before swallowing is not necessary for tinidazole.Tinidazole tablets are film-coated and can be swallowed whole with water.

Chewing the tablets may alter their release and absorption, and may also cause a bitter aftertaste.
