PCOL LAB m1 Exam Questions and
Answers
Vital - correct answer-utmost importance
Signs - correct answer-indicating the presence or existence of something
VITAL SIGNS - correct answer-• provide critical information about a patient's overall
state of health.
VITAL SIGNS - correct answer-• They provide critical and necessary information (hence
the term
'vital') about the state of health of an individual.
VITAL SIGNS - correct answer-are significant values to detect or monitor medical
problems.
THE FOUR MAIN VITAL SIGNS - correct answer-• Body temperature
• Pulse rate
• Respiratory rate
• Blood pressure
o5
th = Pain
o GAIT / Ambulatory
o Oxygen Saturation
PARTICULARLY, VITAL SIGNS CAN: - correct answer-1. identify the existence of an
acute medical problem;
2. serve as means of rapidly quantifying the magnitude of an illness as
well as the coping mechanisms of the body against the resultant
physiologic stress (e.g., the more deranged the vitals are, the sicker
the patient is); and
3. serve as markers of chronic disease states (e.g., hypertension).
*** Vital signs can be measured in a medical setting, at home, at the site of a
medical emergency, or basically anywhere. ***
, BODY TEMPERATURE - correct answer-is the measure of the ability of the body to
generate or get rid of
heat
THERMOREGULATION - correct answer-• balance between heat production
mechanisms and heat loss
mechanisms that occur to maintain a constant body temperature
HYPOTHALAMUS - correct answer-thermoregulatory center of the body
BODY HEAT - correct answer-primarily produced by the body through metabolism
If the body is too cold, it needs to warm up through: - correct answer-• Vasoconstriction
• Thermogenesis
• Hormonal thermogenesis
Vasoconstriction: - correct answer-The blood vessels under the skin narrows which
decreases the blood flow to the skin, thereby retaining heat inside
the body.
Thermogenesis: - correct answer-The organs of the body produce heat in variety of
ways, for example the muscle shivers to produce heat
Hormonal thermogenesis - correct answer-The thyroid gland releases hormones to
increase metabolism which increases the energy the body makes
and the amount of heat it produces.
If the body is too warm, it needs to cool down through: - correct answer-• Vasodilation
• Sweating
Vasodilation - correct answer-The blood vessels under the skin widens which
increases the blood flow to the skin, releasing the inner heat from
the body through radiation.
Sweating - correct answer-The sweat glands are activated, releasing sweat which
cools the skin as it evaporates, thereby lowering the core
temperature.
TYPES OF BODY TEMPERATURE - correct answer-1. Core
2. Surface Temperature
Core - correct answer-• is the temperature of the deep tissues of the body
• It remains constant around the average of 37°C (98.6°F).
Surface Temperature - correct answer-• pertains to the temperature of the skin layers
and
