Term: Agent that kills bacteria

• Bacteriostatic
• Super Infection
• Selective Toxicity
• Bactericidal - D) Bactericidal

Term: Drugs that slow down the growth and replication of bacteria without causing cellular death

• Bacteriostatic
• Super Infection
• Selective Toxicity
• Bactericidal - A) Bacteriostatic

Term: A new infection emerging during the treatment for a primary infection

• Bacteriostatic
• Super Infection
• Selective Toxicity
• Bactericidal - B) Super Infection

Term: A new infection generally caused by Broad Spectrum Antibiotic use creating an environment that Normal Flora takes over.

• Bacteriostatic
• Super Infection
• Selective Toxicity
• Bactericidal - B) Super Infection

Term: The ability of a drug to injure a target cell or organism without injuring other cells/organisms that are in intimate contact with the target.

• Bacteriostatic
• Super Infection
• Selective Toxicity
• Bactericidal - C) Selective Toxicity

Term: Drugs that are effective against many types of organisms/bacteria.

• Broad Spectrum
• Narrow Spectrum
• Susceptibility
• Viruses - A) Broad Spectrum

Term: Drugs that are primarily effective against one or a limited type of

organisms/bacteria.

• Broad Spectrum
• Narrow Spectrum
• Susceptibility
• Viruses - B) Narrow Spectrum

Term: Vulnerability of the bacteria to an antibiotics' effects.

• Broad Spectrum
• Narrow Spectrum

Generally speaking, gram + bacteria take on what color when staining is performed?

• green
• yellow
• purple - D) purple

Generally speaking, gram - bacteria take on what color when staining is performed?

(SATA) A serious issue is when a bacteria becomes resistant to a drug, i.e. MRSA or VRE. Which of the following actions could result in a resistant bacteria?

1) Genetic Mutation of the Microorganism 2) Inadequate dose of an ABX 3) Patient not taking ABX for entire therapy duration 4) Sparingly using Broad Spectrum ABX when possible 5) Mainly using Narrow Spectrum ABX 6) Not using the appropriate ABX first

A) 1,2

B) 4,5,6

C) 1,2,3,6

D) 2,3,4

• All are causes
• None are causes - C) 1,2,3,6

Rationale:

Genetic Mutations can be caused by 2,3, and 6. The key is a swift but thorough kill of the microorganism. Meaning, use the appropriate ABX, using the correct dosage, and for the appropriate durations. Any shortage of one of these could increase the resistance of the microorganism to further treatments.

(T or F) It is acceptable to save your remaining antibiotics, if your feeling better and the symptoms have diminished, and use them later if needed?True False - False

Rationale:

You should always complete an ABX regiment no matter how you feel. This ensures that the microorganism is killed. Saving the antibiotics for later use could cause a resistant microorganism because the new scenario might be a different microorganism that requires a different ABX.

(T or F) It is acceptable to take someone else's antibiotics because they are all the same anyways.

True False - False

Rationale:

You should always complete an ABX regiment no matter how you feel. This ensures that the microorganism is killed. Saving the antibiotics for later use could cause a resistant microorganism because the new scenario might be a different microorganism that requires a different ABX.

(T or F) It is advisable to take antibiotics for a viral infection.True False - False

Rationale:

Antibiotics are for bacteria not Viruses. Antivirals should be taken for Virus infections.

(T or F) ABX can cause organ toxicity. The two main organs a prudent nurse would want to watch for this to happen to are the kidneys and the liver.True False - True

Rationale:

Remember the liver metabolizes a lot of things, especially medicines, and the kidneys filter out these things just the same. Both meaning over time buildups can occur creating toxic scenarios.

MOA: We know that Beta-Lactam ABX like Amoxicillin interfere with/inhibits bacterial cell wall synthesis.True False - True

MOA: We know that Beta-Lactam ABX like Ciprofloxacin interfere with/inhibits

bacterial cell wall synthesis.True False - False
