Which of the following antiviral medications inhibits neuraminidase enzyme?

Acyclovir

Oseltamivir

Efavirenz

Rilpivirine.

Answer and Explanation

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 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.

A. Jaundice B. Vision changes C. Hearing loss D. Orange-colored urine E. Numbness in the hands or feet.

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

Explanation

Jaundice, vision changes and numbness in the hands or feet are possible adverse effects of the drugs used to treat tuberculosis.The nurse should instruct the client to report these signs or symptoms as they may indicate liver damage, optic neuritis or peripheral neuropathy respectively.

Choice C is wrong because hearing loss is not a common side effect of these drugs.Hearing loss may be caused by other drugs such as aminoglycosides.

Choice D is wrong because orange-colored urine is a harmless side effect of rifampin and does not need to be reported.

The nurse should inform the client about this expected change and reassure them that it is not harmful.

The normal ranges for liver function tests are:

• AST: 10-40 U/L

• ALT: 7-56 U/L

• ALP: 45-115 U/L

• Bilirubin: 0.1-1.2 mg/dL

The normal range for visual acuity is 20/20.

The normal range for sensation is intact and symmetrical in all extremities.
