|
hyperthermia
|
|
what temp is considered hyperthermic?
|
105.8 F. or 41 C.
|
|
what triggers the fever response and act on the hypothalamus to raise the body's set point above normal?
|
pyrogens.
|
|
heat production in the body is caused by?
|
metabolism
basal metabolic rate muscle activity shivering |
|
the sum of all chemical and physical processes in the body which energy is made so the living organism can use it is?
|
metabolism
|
|
rate of energy utilization by the body to maintain essential activities like breathing?
|
BMR
basal metabolic rate. |
|
name 4 causes of heat loss?
|
radiation
conduction convection evaporation |
|
name some factors that affect temperature?
|
age,brain injury, weight,infection.
|
|
what are some contraindications to taking oral vs. rectal temperatures?
|
rectal is a more accurate reading. rectal is 1 degree higher than oral. rectal is a core temp & oral is a surface temp. rectal. 2-4/oral. 3-5
|
|
this is felt after the systolic phase of the cardiac cycle throughout the peripheral arteries?
|
pulse
|
|
what is the normal pulse rate for an adult?
|
60-100 bmp
|
|
the volume of blood pumped by the heart in one minute?
|
cardiac output.
|
|
the volume of blood ejected from ventricles in one cardiac contraction.
|
stroke volume (sv)
|
|
list sites that nurses may use to take a pulse?
|
(peripheral arteries)=carotid, radial, brachial, femoral, popliteal, and pedal pulses( dorsalis pedis-dp,posterior tibial-pt)
|
|
what are 4 characteristics of a pulse?
|
pulse rhythm, amplitude(volume), rate, elasticity, equality.
|
|
what is it called when the apical pulse is greater the the peripheral(radial) pulse?
|
pulse deficit
|
|
what does a pulse deficit indicate?
|
poor peripheral circulation/perfusion.
|
|
what methods can be used to check if a client has a pulse deficit?
|
an apical-radial pulse=this is a simultaneous measurement of both apical and radial pulses for 60 sec. it checks contraction strength of LV.
|
|
name a few factors that affect pulse rate?
|
kids ^, male l, activity, fever ^,meds-bata blockers l, hemorrhage ^, stress ^, position changes l, vagal stimulation l(GI tract-gaggging,defecating)
|
|
def: the act of breathing for 1 min. cycle of inspiration and expiration.
|
respiration rate
|
|
3 processes of respiration are?
|
ventilation
diffusion perfusion |
|
what is the mechanical movement of gasses into and out of the lungs?
|
ventilation
|
|
what is the movement of O2 and CO2 from blood to alveloli
|
diffusion
|
|
distribution of RBC from pulmonary capillaries to the rest of the body through the circulatory system.
|
perfusion
|
|
what should you look at when assessing respirations?
|
rate, rhythm, effort, and depth.
|
|
should be evenly spaced, if irregular take respiration for full min?
|
rhythm
|
|
this is reported as breaths per min?
|
rate= count for 30 sec and multiply by 2.
|
|
what are normal respirations for an adult?
|
12-20 per min.
|
|
should you have eupnea or dypnea when breathing?
|
EUPNEA= no effort when breathing.
dyspnea= having trouble when breathing. |
|
clients should have full movement of chest when breathing? t or f
|
true
|
|
very shallow breathing
|
hypoventilation
|
|
very deep respirations
|
hyperventilation
|
|
name some factors that affect respirations?
|
exercise, acute pain ^, anxiety, smoking(increase rate at rest),body position, medications, neurological injury(cheyne-stokes)hemoglobin funct
|
|
measurement of arterial wall pressure created as blood flows through the arteries throughout the cardiac cycle.
|
blood pressure
|
|
is the higher of the 2 blood pressure readings. is measured as the left ventricle ejects blood?
|
systolic BP
|
|
is the lower reading on the blood pressure value. measured when the heart relaxes?
|
diastolic BP
|
|
what is the difference called b/ the diastolic and systolic B/P
|
pulse pressure= if BP is 120 / 80 then pulse pressure would be 40.
|
|
what is the normal range for pulse pressure?
