Q & A
What are antimicrobial agents?
-Antimicrobial agents are a class of medications that work to eliminate or inhibit the growth and spread of potentially harmful microorganisms such as bacteria and fungi.
Why are respiratory therapists required to understand antimicrobial agents?
-Respiratory therapists need to understand antimicrobial agents because they are often involved in the treatment of respiratory infections, and knowing these medications helps them to provide appropriate care to patients.
How are antimicrobial drugs typically classified?
-Antimicrobial drugs are typically classified according to the microorganisms they act upon, such as antibiotics for bacteria, antifungals for fungi, and anti-pneumocystis agents for Pneumocystis infections.
What is the most common type of antimicrobial agent?
-The most common type of antimicrobial agent is antibiotics, which are used to fight against different types of bacteria.
When might a medical care provider consider prescribing an antibiotic?
-A medical care provider might consider prescribing an antibiotic when a patient shows signs and symptoms of a bacterial infection, such as fever, chills, diaphoresis, green or yellow sputum, and an increased white blood cell count.
What tests can be used to determine which antibiotic should be administered?
-A culture and sensitivity test or a gram stain test can be used to identify the specific bacterial organism present, allowing the selection of the most appropriate antibiotic agent.
Which inhaled antimicrobial agents should a respiratory therapist be familiar with?
-A respiratory therapist should be familiar with inhaled antimicrobial agents such as penicillin for gram-positive bacteria, gentamicin for gram-negative bacteria, pentamidine for Pneumocystis carinii pneumonia, tobramycin for cystic fibrosis patients, and trionam or k-stone for pseudomonas infections.
What is the role of aerosolized tobramycin in treating cystic fibrosis patients?
-Aerosolized tobramycin is often administered to treat patients with cystic fibrosis, particularly to combat Pseudomonas aeruginosa infections.
What medication is administered to treat RSV in children?
-Ribavirin, also known as Virazole, is administered to treat respiratory syncytial virus (RSV) in children.
What is Xenamavir, and what is it used to treat?
-Xenamivir, also known as Relenza, is an approved medication used to treat the flu.
Is the information provided in the video script meant to replace professional medical advice?
