Module 6- Infectious diseases/
Antibiotics Test Questions and
Revised and Updated Answers (2025-
2026)
Antibiotic - Answer drugs that have the ability to destroy or interfere with the development of
a living organism, typically bacteria.
Infectious diseases - Answer caused by pathogenic (disease-causing) organisms such as
bacteria, fungi, and parasites as well as by viruses.
Bacteria - Answer defined as single-celled microorganisms. They can be found virtually
everywhere and can either be harmless or very dangerous.
Bacteria can be classified as either: - Answer - Gram-positive or Gram-negative. This
classification refers to how they respond to the Gram stain procedure.
- whether they are an aerobe or anaerobe
Gram-positive - Answer bacteria stain purple
Gram-negative - Answer stain pink
- Gram-negative bacterial infections are harder to treat because Gram-negative bacteria have a
more complex cell wall structure.
Aerobe - Answer a bacterium that grows in the presence of air or requires oxygen for growth
Anaerobe - Answer a bacterium that does not require oxygen in order to grow. Anaerobes, for
instance, are most commonly found in the GI tract.
it is important to understand generally that bacteria do not simply cause a single disease: rather,
multiple disorders are possible depending on where in the body the bacteria accumulate. -
Answer For example, the bacteria streptococcus pyogenes is the specific bacteria responsible
for the common throat infection known as strep throat. This bacterium is spread through
airborne droplets when someone with the bacteria coughs or sneezes. It can also be spread by
, There are also common infections associated term-13with certain bacteria based on where they
are found naturally or how the pathogen is acquired. Take for instance, the bacteria E.coli.
Although typically found within the intestines of a healthy individual, when someone becomes
exposed to a pathogenic strain of E.coli, often via contaminated food, it often presents as
diarrhea because of where the bacteria naturally end up by way of the digestive tract.
One last factor is related to where the person contracts the infection—different types of
bacteria are found in the environmental community compared to a healthcare setting.
health care associated infection - Answer - an infection acquired during the course of receiving
treatment for another condition in a health care institution.
- Generally, healthcare-associated infections are much more difficult to treat because the
microorganisms have been exposed to strong antibiotics in the past; therefore, they are
resistant to many treatments.
Examples of common Gram positive/negative bacteria - Answer Gram positive:
staphylococcus aureus- skin & skin structure infection
streptococcus progenies -strep throat
enterococcus faecalis- UTI
Gram negative:
psueodomonas aeruginosa- meningitis, pneumonia
klebsiella pneumoniae - UTI, pneumonia,
escherichia coli- pneumonia, UTI, diarrhea
enterobacter species- urinary & respiratory tract infections
Antibiotic spectrum - Answer bacteria that are susceptible to the antibacterial actions of a
particular drug.
Broad Spectrum - Answer an antibiotic that is effective against a wide variety of both Gram-
positive and Gram-negative bacteria.
Bacteria Resistance - Answer the ability of some bacteria to resist the actions of antibiotics.
MRSA - Answer - stands for methicillin-resistance Staphylococcus aureus.
