A nurse is caring for a client who has tuberculosis and is prescribed rifampin, an antitubercular drug. The nurse should instruct the client about which potential side effect of rifampin?

Inappropriate antibiotic use leads to the emergence of resistance.This is a well-established fact that is supported by the CDC and other organizations.Resistance can occur when antibiotics are used unnecessarily, excessively, or incorrectly, and can lead to infections that are harder to treat and more costly.

Choice A is wrong because antibiotic guidelines in critical care do not necessarily reduce the hospital length of stay.Although some studies have suggested that adherence to pneumonia guidelines may improve outcomes in severe pneumonia, other studies have found no significant effect of antibiotic stewardship on hospital length of stay or mortality in critically ill patients.

Therefore, this statement is not universally true.

Choice C is wrong because antibiotic dosing has a significant effect on antimicrobial resistance.Optimal dosing of antibiotics can help eradicate infections, prevent relapse, and minimize the selection of resistant bacteria.Conversely, suboptimal dosing can lead to treatment failure, prolonged infection, and increased resistance.

Therefore, antibiotic dosing should be carefully adjusted according to the pharmacokinetic and pharmacodynamic properties of the drug and the patient.

Choice D is wrong because an antibiotic stewardship programme leads to a decrease in antimicrobial resistance, not an increase.An antibiotic stewardship programme is a coordinated effort to improve and measure the appropriate use of antibiotics by promoting the selection of the optimal drug regimen, dose, duration, and route of administration.Such programmes have been shown to reduce antibiotic consumption, resistance rates, adverse events, and costs in various settings.

Therefore, this statement is false.

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.
