TEST 2 Flashcards
What do we check when taking vital signs?
Temp
Pulse
Respiration
BP
Pain
Oxygen saturation
What is the normal range for temp?
35.9-38 C
96.7-100.5 F
What is the normal range for pulse?
60-100bpm
What is the normal range for respirations?
12-20 breathes per min
What is the avg bp?
120-80 mmHg
What is the pulse pressure?
30-50 mmHg difference between systolic and diastolic
What is the bodys primary source of heat?
Metabolism
What is basal metabolic rate?
Occurs at rest, heat is still being produced
What are the factors affecting temp?
-Elderly - lose muscle & fat
-Males - higher temp due to hormones
-Circadian rythm - temp 1-2 lower in AM & peak in afternoon/early evening
Environmental temps
What is hyperthermia
What is hypothermia
hyperthermia -elevated temp
hypothermia - lower temp
What is pyrexia (febrile)
What is afebrile?
pyrexia (febrile) - fever
afebrile - no fever
What are the sites we can assess temp?
Oral - glass for contact precaution
Axillary
Tympanic
Rectal
Forhead - temporal
What is cardiac output?
Volume of blood pumped by heart each minute
How do we calculate the cardiac output?
SV X Heart rate = CO
What is the min blood volume available before heart speeds up contractions to make up for it?
4-6 liters
Increased volume = heart rate slower
Decreased volume = heart rate faster
What is the pulse rate?
number of beats felt in 1 min
What are the numbers for bradycardia and tachycardia?
Bradycardia - >60
Tachycardia - <100
What are the sites to check for a pulse?
Temporal
Carotid - Emergecy
Apical - 4-5 intercostal space and mid left calvicular
Brachial
Radial
Femoral
Popliteal
Posterior tibial
Dorsalis pedis
What 3 scenarios do you need to check the apical pulse
Giving cardiac meds, abnormal heart rythum, history of cardiac issue
Diaphragm pick up what frequency sounds?
Bell picks up?
Diaphragm - high frequencey
Bell - low
Characteristics of pulse
Rhythm
Force/strength
Rhythm - regular or irregular
(dysrhythmia/arrhythmia)
Force - 0 - no pulse
1+ barely/weak
2+ normal
3+ bounding
What part of the brain controls our respirations?
Medulla oblongata - sensitive to opioids
*Regulated by levels of carbon dioxide, oxygen & hydrogen Ion concentration in the blood
What does
Bradypnea
Tachypnea
Apnea
Dyspnea
Bradypnea - slow breathing
Tachypnea - fast breathing
Apnea –no breathing
Dyspnea - difficulity breathing
What does the oxygen saturation measure?
% of hemoglobin bound to oxygen in arteries
**how saturated your hemoglobin is with oxygen
What is COPD?
Lacking in o2 molecules/ normal is lower 80-90’s
What can result in abnormal results for oxygen saturation?
Anemia -lacking in hempglobin
Nail polish
Impeding blood flow while taking BP
What does the BP meausre?
amount of force by blood against walls of artery
What does systolic and diastolic pressure measure?
Systolic - period of heart muscle contraction
Diastolic - period of heart muscle relaxation
What are the risks for hypertension
Family history
Obesity
Smoking
heavy alcohol
High sodium
Sedentary lifestyle
stress
diabetes
Elderly african amerian
high cholestrol
WHat are the metrics for stage 2 hypertension?
Systolic => 140
Diastolic => 90
What are the ranges in normal that determines orthostatic hypotension?
Systolic decrease >20mm HG when changing positions
Diastolic decreased > 10 mm Hg when changing positions
HR increase 10% when changing positions
What are the risk factors for orthostatic hypotension?
Volume depletion
Dehydration
anemia
prolonged bedrest
anti-hypertensive meds
What is transduction?
Nociceptors stimulated and release chemicals
What is transmission?
Pain impulses travel from peripheral nerve fibers
What is perception?
Brain interprets pain
WHat is modulation?
Inhibition of pain impulse by neuromodular compounds
