Which of the following antiviral medications inhibits neuraminidase enzyme?

Acyclovir

Oseltamivir

Efavirenz

Rilpivirine.

Answer and Explanation

The Correct Answer is B

This is because oseltamivir is a neuraminidase inhibitor, which means it blocks the enzyme that helps the influenza virus to spread from cell to cell. By preventing the release of new virus particles, oseltamivir reduces the duration and severity of influenza infection.

Choice A is wrong because Acyclovir is wrong because it is a nucleoside analog that inhibits viral DNA synthesis.

It is effective against herpes simplex virus (HSV) and varicella zoster virus (VZV), but not against influenza virus.

Choice C is wrong because Efavirenz is wrong because it is a **non-nucleoside reverse transcript

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

Explanation

The nurse should include these instructions in the teaching because:

• Tetracycline should be taken on an empty stomach to avoid interference with absorption.

• Dairy products should be avoided while taking this drug because they contain calcium, which can form insoluble complexes with tetracycline and reduce its effectiveness.

• Sunscreen or sun avoidance should be used while taking this drug because it can cause photosensitivity, which increases the risk of sunburn and skin damage.

• Plenty of fluids should be drunk while taking this drug because it can cause nephrotoxicity, which is damage to the kidneys.

Choice E is wrong because vaginal itching or discharge is not a common side effect of tetracycline.It may indicate a superinfection, which is a secondary infection caused by the disruption of normal flora by antibiotics.

This should be reported to the health care provider as soon as possible.

A. Take the medication with an antacid to reduce gastric irritation. B. Drink plenty of fluids to prevent crystalluria. C. Avoid sexual intercourse until treatment is completed. D. Chew the tablets thoroughly before swallowing. E. Electrocardiogram.

Correct Answer is C

Explanation

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.
