Multiple choice

Which of the following antibiotics is known to cause ototoxicity?

  1. Gentamicin

  2. Penicillin

  3. Amoxicillin

  4. Erythromycin
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gentamicin is an aminoglycoside antibiotic that can cause ototoxicity, particularly at high doses or with prolonged use. It can damage the hair cells in the inner ear, leading to hearing loss and balance problems.

Multiple choice

What is the primary mechanism of ototoxicity caused by aminoglycoside antibiotics?

  1. Interference with neurotransmitter release

  2. Inhibition of protein synthesis

  3. Damage to hair cells in the inner ear

  4. Blockage of ion channels in the cochlea
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aminoglycoside antibiotics primarily cause ototoxicity by damaging the hair cells in the inner ear, which are responsible for hearing and balance. This damage can lead to hearing loss and vestibular dysfunction.

Multiple choice

What is the primary mechanism of ototoxicity caused by quinine?

  1. Interference with neurotransmitter release

  2. Inhibition of protein synthesis

  3. Damage to hair cells in the inner ear

  4. Blockage of ion channels in the cochlea
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Quinine primarily causes ototoxicity by blocking ion channels in the cochlea, particularly the potassium channels. This disruption of ion balance can lead to hearing loss, especially in the high-frequency range.

Multiple choice

Which of the following drugs is used to treat tuberculosis and can cause ototoxicity?

  1. Streptomycin

  2. Isoniazid

  3. Rifampin

  4. Pyrazinamide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Streptomycin is an antibiotic used to treat tuberculosis that can cause ototoxicity, particularly at high doses or with prolonged use. It can damage the hair cells in the inner ear, leading to hearing loss and balance problems.

Multiple choice

What is the primary mechanism of ototoxicity caused by streptomycin?

  1. Interference with neurotransmitter release

  2. Inhibition of protein synthesis

  3. Damage to hair cells in the inner ear

  4. Blockage of ion channels in the cochlea
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Streptomycin primarily causes ototoxicity by damaging the hair cells in the inner ear, which are responsible for hearing and balance. This damage can lead to hearing loss and vestibular dysfunction.

Multiple choice

Which of the following drugs is used to treat fungal infections and can cause ototoxicity?

  1. Amphotericin B

  2. Fluconazole

  3. Itraconazole

  4. Voriconazole
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Amphotericin B is an antifungal drug that can cause ototoxicity, particularly at high doses or with prolonged use. It can damage the hair cells in the inner ear, leading to hearing loss and balance problems.

Multiple choice

What is the primary mechanism of ototoxicity caused by amphotericin B?

  1. Interference with neurotransmitter release

  2. Inhibition of protein synthesis

  3. Damage to hair cells in the inner ear

  4. Blockage of ion channels in the cochlea
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Amphotericin B primarily causes ototoxicity by damaging the hair cells in the inner ear, which are responsible for hearing and balance. This damage can lead to hearing loss and vestibular dysfunction.
