Week 2 Flashcards
Range core body temperature
36.0-37.0
97-99.5
What regulates body temperature
Homeostasis+ set point
Heat production
Heat loss
3 factors that affect body temp
Age babies+ old people < temp
Gender: women have high temp variations
Circadian rhythm- highest 4-7 pm
Temperature extremes affect body temp
Environmental temp
> metabolic rate in body > temp
So exercise, stress + illness
Febrile
Afebrile
Temp above normal
Afebrile= normal temp
Hypothermia
<97.0c
Fever
101> is natural disease fighting, not too harmful
Above 104 is very harmful
In older adults fever
Is a sign you’re in the later stage of a Disease
Older adults and infants
Small change is important. Takes a lot on their metabolize to > temp
Core body temps
Rectal or tympanic
Interventions for fevers
Monitor VS FLUID SEIZURES (in extreme cases) Administer antipyretic meds Administer IV fluids Apply ice (extreme)
Don’t use rectal
Diarrhea, bowel surgery, diseases of the rectum, nutripenic (immunocomprimised), quadriplegics, no CV surgeries
Stimulate vagus nerve= fainting
> age pulse
<
Women have slightly higher pulse
Infancy pulse range
100-160
Adult 60-100
The vagus nerve
> temp pulse?
Tachycardia
Ventricle strokes a lot, so less blood is getting out so higher pulse. Stroke volume is less
< BP
> temp
Bradycardia
<60 bpm
Men have lower HR so elderly + adults
Hypothermia < pulse rate
Vagostimulaiton/ bradycardia < Pulse
SEVERE CHRONIC PAIN < pulse
Dysrhythmias
Regular irregular (same irregular pattern)
Irregular irregular (no predictability)
Ventral ejection is the same as
Pulse= pulse generation= pulse wave= ventricular opening
Characteristics of pulse
Rate, quality, Rhythm
Indicate effectiveness of system & quality of blood flow
Quality of pulse rate determined by the force of the blood flow
Quality of pulse
0=absent 1= threats 2=weak 3= normal 4= bounding
Cardiac output is calculated as
Heart rate* stroke volume
Temporal artery
Front of upper part of ear
Carotid artery
Under the chin towards the neck
Best representative of the quality of the pulse rate directly front he heart or aorta
Brachial artery
Radical artery
Need to accurate put the BP cuff on it
Bend arm, pulse is at the antecubitol space locate medically
Anywhere within a 2in range above where the arm flexes
Radial you know this
Femoral artery
Have person bend their thigh up
Located in the medial aspect of thigh, halfway btn the anterior superior iliac spine & the synthesis pubis
Popliteal
Patient flexes their knee, reach behind and palpate the lateral aspect of the fossa
Dorsalis pedis
Top of foot
Wiggle their great toe. Tenden goes towards ankle, palpate the lateral side of that
Posterior tibial
Behind medial malleolus in each side
Always palpate both sides of parallel pulse except temporal and carotid
If the stroke volume is decreased
The pulse amplitude decreases
Doppler monitors
Feel for skin temp and capillary refill. They’re getting good pulses but you can use the Doppler to hear that artery
Knee surgery on L side. Lower leg really swelled. You wanna assess those pedal pulses on that Left leg for circulation . Or edema
Difficult pulses
Doppler monitor
Check both sides
Pulse documentation
Rate
Rhythm
Quality
68 regular, even
72 regularly irregular, and bounding
52 right dorsalis pedis via Doppler
NANDA Diagnosis regarding tissue perfusion
Decreased cardiac output
Ineffective tissue perfusion- peripheral
Deficient fluid volume
Acute pain
Factors that affect respirations
Age lungs get bigger resp. < Gender females breathe more Stress, anxiety Exercise balance breathe faster Acid-base inbalance will change respirations
Factors that affect respirations
Meds.
Altitude
Pain
Anemia < in O2 so increase is respirations
Fever
Respiratory diseases
-body position will affect ability of your lungs to expand. Tripod position is common with COPD
Eupnea
Normal rate (12-20)
Tachypnea and Bradypnea
You know
Apnea
Period of no breathing
Note quality of respirations
Unlabored, quiet, effortless
Labored, shallow, deep, gasping, painful
Note Rhythym
NANDA NURSING DIAGNOSES
Ineffective breathing patterns
Impaired gas exchange
Risk for activity intolerance
AnEroid
Digital
BP cuff
Aneroid- sphyg
Factors affecting BP
Age, older adults higher BP. Have a < in vascular existence (> plasticity of blood vessels) esp. systolic
Circadian Rhythm lowest in morning highest in later afternoon
Gender. Women are lower than men until menopause
Food intake
Exercise
Other factors that affect BP
Overweight people Emotional state activate autonomic system > stress, > BP Body position Race: HTN prevalent in AA Medication
BP cuff sizes
Cuff to big, low reading
Cuff to narrow, false high
Bladder width should be 40 of curcumference
Preparation for patient’s
Rested for 5 minutes Has not consumed coffee Has not smoked for 30 min. Sitting in a straight back chair Feet resting on ground Arm at heart level Patient is quiet
BP measurement
5 separate phases
Phase 1 systolic
Phase 5: diastolic
3 numbers in pediatric
1st, 4th, & 5th
Also in exculpatory gap
To put a Bp cuff
Medial aspect of antecubital foss
1-2 inchesfossa, same
Deflate cuff at
2-3 mm per second
Can you use a pipliteal artery for BP?
The systolic number is 10-40 mmHg higher. Diastolic the same
Use thigh cuff or large regular cuff.
Auscultatory Gap
See them in patients with HTN
Important bc common in people with atherosclerosis (plaque)& > arterial stiffness
Identify these gaps. Too high to have gone away and then it picks up again.
Top #, second number # whenyou reheard the best, 3# last beat
Causes of false readings
Mono meter not calibrated to “0” Viewing the needle below eye level Releasing the valve too slowly Reinflating the bladder during auscultation missing an ausculatory gap
Causes of false low readings
Viewing the needle above eye level Releasing valve too rapidly Not placing the stethoscope over the artery Not pumping 30mmHg above the Sbp Missing an auscukatory gap
What BO reading will you get with a Doppler monoter
The systolic reading
Moderate HTN
SEVERE

What organs are at risk for damage in BP
Brain
Heart
Kidney
Pulse pressure
A mathematical equation
Systolic-diastolic
Larger someone’s PP means their arteries are not compliant
Complaint arteries have elasticity
Non complaint/ resistance are tight
PP determined by how compliant ur arteries are & ur stroke volume
For a given stroke volume
Increased complaint= smaller pulse pressure
Decreased compliance= higher pulse pressure
A larger stroke volume fives a large pulse pressure at any compliance
Why do non compliant arteries take more time and pressure
Dump a lotta blood into artery at one time, that opens a bit, as blood flows through it’ll close again, how wide it gets vs how small it gets (systolic versus diastolic) is bigger than normal then it’ll flex smaller than normal
Boncomplaint aretiers do not open very wide and cause more pressure and it’ll take more time for the blood to pass
Pulse pressure is going to be higher
With higher volume
It’ll be much higher for someone who has arteries that are not complitany
Artery that is stiff will take longer to pass blood through
Arterial resistance increases with age
