NursingTest 4 Flashcards
What are the 6 vital signs that are taken to give some indication of a person’s state of health
temperature pulse respiration blood pressure pain level oxygen saturation
define metabolism
cellular chemical reactions in the body
what causes a fever and what are agents that cause fever
when metabolism increases, more heat is produced
pyrogens are agents that cause fever
what is acts as a thermostat and controls body temperature by a feedback mechanism
hypothalamus, located btw the cerebral hemispheres
when the body heat rises above normal, the hypothalamus sends out a signal through the nervous system that cause ___ ___ and ___
vasodilation
sweating
inhibition of heat production
heat loss occurs through what four ways
radiation
conduction
convection
evaporation
define pyrexia
fever
occurs when normal mechanisms of the body cannot keep up with the excessive heat production and body temperature rises
Temp rises above 100.2 or 37.9 C
define stroke volume
the volume of blood pushed into the aorta per heartbeat
define systolic pressure
the maximum pressure exerted o the artery during left ventricular contraction
define diastolic pressure
the lower pressure exerted on the artery when the heart is at rest btw contractions
What is the range of normal body temperature and what is the average temp of a young healthy adult
- 5-99.5 AND 36.4-37.5
98. 6 OR 37
what temperature usually indicates a fever
100.2 OR 37.9
during pregnancy, how different in the average temp and why
may stay at a high normal because of an increase in the patients metabolic rate
what are the stages of fever
onset=maybe be gradual/suddenly
febrile=body temp rises
defervescence=lowering of body temp
fevers are classified into what four categories
constant=continuously elevated
intermittent=temp alternates rising and falling
remittent=temp falls in morning, then rises later on in day
relapsing=temp falls to normal and then rises again in a repeated pattern
what are some common pulse points
radial temporal carotid femoral apical, over the apex popliteal pedal posterior tibial
the apical, rather than the radial pulse, is taken on children younger than ____
2 years
what are the average pulse rates for: normal pulse range some althletes adult male adult female child age 5 child age 1 newborn
normal pulse range=60-100 some althletes=45-60 adult male=72 adult female76-80 child age 5=95 child age 1=110 newborn=120-160
what are some factors that affect pulse rate
age body build and size blood pressure drugs emotions blood loss exercise increased body temp pain
while taking the pulse, what else should be noted
rate
rhythm
volume
What are the normal range of respirations for the age groups: elderly healthy adult adolescent child age 3 child age 1 newborn
elderly=16-20 healthy adult=12-20 adolescent=16-20 child age 3=20-30 child age 1=20-40 newborn=30-80
what are some symptoms of hypoxia that may be noted as a result of low oxygen supply in the blood
apprehension and restlessness
confusion, dizziness
change in the level of consciousness
cyanosis particularly around the mouth and in nail beds
