1. what are the formulas for conversion of farenheit to celcius and celcius to kelvin?
5/9 X( Farenheit- 32)

Celcius + 273
2. explain Boyl's, Charles, Dalton's , gay-lussac gas laws
• Dalton's law: describes the relationship between partial pressure and the total pressure in a gas mixture
• according to the law, the pressure of a mixture of gases must equal the sum of  partial pressures of all component gases

partial pressure= fractional concentration X total pressure

Boyl's law: volume of gas varies inversly with it's pressure

• Pressure X volume = K
• constant is temperature, mass

Charles law: volume of gas varies directly with temperature

V/T=K; constant is pressure, mass

Gay-lussac's law:pressure exerted by a gas varies directly with it's absolute temperature

P/T=K; constant is volume, mass
3. Describe situations when communicating with patients/ families would be suboptimal, how do you facilitate communication.
language barrier, religious differences, cultural barriers, handicaps

use different channels of communication, get a translator, determine preferences
4. Define SOAP
• Subjective
• Objective
• Assessment
• Plan
5. Distinguish between laminar and turbulent flow
• Laminar flow: a fluid moves in discreet cylindrical layers or stream lines.
• Poiseuille's Law: change in pressure is = 8N1V/ pi r

Turbulent flow: pattern of flow through a tube becomes irregular eddy currents flowing in a chaotic pattern

Change in pressure= flV2/4pi2r5
