FUNDAMENTALS OF RESPIRATORY CARE
EXAM #1 QUESTIONS AND ANSWERS
Therapist-Driven Protocols - ANSWER-algorithm-like care plans that are used to appropriate
therapy
Evidence Based Medicine - ANSWER-A review of evidence for effective treatment primarily
using randomized controlled studies.
Kinetic theory - ANSWER-describes a gas as a large number of submicroscopic particles
(atoms or molecules), which are in constant rapid motion.
• Small molecules
• Kinetic activity noted by the Brownian movement
• Elastic, molecular collisions
• Kinetic activity increases with increased temperature
• Molecules are neutral
14 - ANSWER-What is the gram atomic weight of nitrogen?
12 - ANSWER-What is the gram atomic weight of carbon?
add the weight of the molecules in a substance - ANSWER-how do you find the gram molecular
weight (GMW)?
22.4 - ANSWER-What is the molar volume in Liters at STPD?
Avogadro's Law - ANSWER-Describe Avogadros Law.
1 gram molecular weight of any gas contains 6.02x1023 MOLECULES, 1 mole at STPD, 1 atm,
0degrees celcius, 1 mole of gas occupies 22.4L of volume
density - ANSWER-can be measured in gram/cm2 or g/liter (gases)
1.43 g/L - ANSWER-density of oxygen
1.96 g/L - ANSWER-density of carbon dioxide
0.179g/L - ANSWER-density of helium
the percentage of each individual gas added together /22.4 (at STPD) - ANSWER-What's the
density of a gas made up of 2 or more gases?
add 273 - ANSWER-celcius to kelvin
subtract 273 - ANSWER-kelvin to Celsius
