A nurse is caring for a client who has trichomoniasis and is prescribed tinidazole.
Which of the following instructions should the nurse give to the client?

Take the medication with an antacid to reduce gastric irritation.

Drink plenty of fluids to prevent crystalluria.

Avoid sexual intercourse until treatment is completed.

Chew the tablets thoroughly before swallowing.

Electrocardiogram.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is ["A","B","C"]

Explanation

Here is why:

• Choice A:Monitor the client’s serum creatinine level.

This is correct because vancomycin can cause nephrotoxicity (damage to the kidneys) and serum creatinine is a marker of kidney function.A high serum creatinine level indicates impaired kidney function and may require dose adjustment or discontinuation of vancomycin.

• Choice B:Monitor the client’s serum vancomycin level.

This is correct because vancomycin has a narrow therapeutic range, meaning that there is a small difference between the effective dose and the toxic dose.Monitoring the serum vancomycin level can help to ensure that the drug is within the therapeutic range and avoid toxicity or suboptimal efficacy.

• Choice C:Infuse the drug over at least 60 minutes.

This is correct because vancomycin can cause a hypersensitivity reaction called “red man syndrome” or “red neck syndrome”, which is characterized by flushing, itching, rash, hypotension and tachycardia.

This reaction is not an allergy but a result of histamine release due to rapid infusion of vancomycin.Infusing the drug over at least 60 minutes can reduce the risk of this reaction.

• Choice D:Observe the client for signs of ototoxicity.

This is incorrect because vancomycin is not known to cause ototoxicity (damage to the ears) in humans.Ototoxicity has been reported in animal studies and in vitro studies, but not in clinical trials or case reports involving humans.

Therefore, there is no need to monitor for signs of ototoxicity such as hearing loss, tinnitus or vertigo.

A. “I will report any changes in my vision to my doctor.” B. “I will avoid eating foods that contain tyramine.” C. “I will take this medication on an empty stomach.” D. “I will continue to take this medication until I feel better."

Correct Answer is D

Explanation

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.
