Integumentary system

What is the primary function of antibiotics?

• Stimulate immune response

• Destroy or weaken other organisms, especially bacteria

• Improve cell wall synthesis

• Increase red blood cell count

What is a pathogen?

• A healthy cell

• A type of antibiotic

• A disease-producing agent or organism

• An antiviral medication

Which of the following best describes bacteria?

• Multicellular parasites

• Single-celled microorganisms, some of which are pathogenic

• Viruses that attack white blood cells

• Microscopic fungi

What does a culture and sensitivity test determine?

• Whether a patient is allergic to penicillin

• The number of red blood cells present

• Which medication can treat a specific pathogen

• The oxygen-carrying capacity of blood

What is the purpose of a Gram stain?

• To count white blood cells

• To identify viruses

• To classify bacteria by cell wall type

• To detect kidney function

What was the first antibiotic developed?

• Tetracycline

• Amoxicillin

• Penicillin

• Erythromycin

What important structure do bacteria lack?

• Cell wall

• Cell membrane

• Ribosomes

• Nucleus

Which statement best describes Gram-positive bacteria?

• Do not retain crystal violet stain

• Have no cell wall

• Retain crystal violet stain due to simpler cell wall structure

• Are resistant to all antibiotics

Why are Gram-negative bacteria less susceptible to antibiotics?

• They lack a cell membrane

• They reproduce too quickly

• They have a more complex cell wall structure

• They are not pathogenic

What are broad-spectrum antibiotics effective against?
