Agar is used for susceptibility testing.

F = ΔP/R what do these mean?
F- blood flow
◼ ΔP- the difference in pressure between two points
◼ R – resistance
A nurse states to a client, "Things will look better tomorrow after a good night's sleep." This is an example of which communication technique?
The nontherapeutic technique of "giving false reassurance"
what is consciousness ?
Is an individual’s awareness of external events and internal sensations under a condition of arousal, including awareness of the self and thoughts about one’s experiences
Lag - Adapt to nutrients
Log - Active Growth
Stationary - Growth equals death
Death - Nutrients Consumed

the pressure within capillary beds. Pressures decline from 35 mmHg to 18mmHg along a typical capillary
– pressure within the venous system. This pressure is quite low. The pressure gradient from the venules to the right atrium is only 18 mmHg

Psychosocial Stages of Dev.
For fastidious organisms such as Haemophilus influenzae.
Lysis of the red blood cells causes the release of intracellular coenzyme nicotinamide adenine dinucleotide (NAD or V-factor) into the agar. Hemin (factor X) is available in non lysed cells. (Neisseria gonorrhoeae, Neisseria meningitidis, and haemophilus spp.)

vascular resistance is friction between blood and vessel walls. Friction depends on what two factors?
1. Vessel Length 2. Vessel Diameter
what is the purpose of health history?
1.Provide the subjective database
2.Provides focus for the physical assessment
3.Identifying areas of strength and weaknesses
4.Identify patient health problems, both actual and potential
5.Identify supports
6.Identify teaching needs
7.Identify discharge needs
8.Identify referral needs
Narcolepsy?
involves the sudden, overpowering urge to sleep. The urge is so uncontrollable that the person may fall asleep while talking or standing up.
Narcoleptics immediately enter REM sleep rather than progressing through the first four sleep stages. It can be triggered by extreme emotional reactions, such as surprise, laughter, excitement or anger.
•contains a rich supply of special nutrients that promote the growth of fastidious organisms, for example, chocolate agar, blood agar
•has added inhibitors that discourage growth of certain organisms while allowing the growth of a desired organism, for example, Thayer Martin agar
• permits the differentiation of organisms that grow on the medium, for example, MacConkey agar

What is Broca’s aphasia and Wernicke’s aphasia
inability to produce language and inability to understand language.
What is the principle behind the catalase test ?
The catalase test is a particularly important test used to determine whether the Gram + cocci is a staphylococcus or streptococci. Catalase is an enzyme that converts hydrogen peroxide to water and oxygen gas. The test is easy to perform; bacteria are simply mixed with H 2O 2. If bubbles appear (due to the production of oxygen gas) the bacteria are catalase positive. If no bubbles appear, the bacteria are catalase negative

Upper tract, trachea & bronchi – pseudostratified ciliated columnar ❖Oropharynx and laryngopharynx – stratified squamous ❖Small Bronchioles – simple cuboidal with scattered cilia ❖Alveoli – simple squamous
