Patient Assessment: Vital Signs (U3) Flashcards
Vital signs definition?
Physical signs that indicate an individual is alive
How are vital signs seen?
Observed, measured and monitored to assess an individual’s level of physical functioning, patient must have been sitting for approx. 5 minutes (relax)
What should you do before assessing a patient?
Take a minute to look at the entire patient, all assessments made when seated (ex. patient hygiene level, are they relaxed….)
What are some factors to consider when looking at normal vital signs?
Age/sex/weight/exercise tolerance/condition
What are the four assessments, and why in that order?
- Temperature
- Pulse
- Respiration
- Blood pressure
Least to most invasive
Temperature can vary due to what reasons?
Time of day, illness, stress, exposure to heat/cold
Normal temperature?
36.5-37.7 degrees Celsius
What are the four temperature sites?
Oral, axillary, tympanic, rectal
What is the oral temperature site?
Within the mouth/under tongue
What is the axillary temperature site?
In the armpit
What is the tympanic temperature site?
In the ear canal
What is the rectal temperature site?
Through the anus in the rectum
What is a pulse?
Pressure of the blood felt against the wall of an artery as the heart contracts/relaxes
What are the three things pulse measures?
Rate, rhythm, volume
What is pulse rate?
Number of beats/minutes
What is pulse rhythm?
Refers to regularity
What is pulse volume?
Refers to strength
What is the pulse taken on?
Radial/carotid artery, and on arteries
What are the arteries that pulse is taken on?
Temporal, carotid, brachial, radial, femoral, popliteal, dorsalis pedis, posterior tibial
What is the temporal site?
Sides of the head
What is the carotid site?
Sides of the neck
What is the brachial site?
Inner aspect of forearm at the antecubital space
What is the radial site?
Inner aspect of the wrist, above thumb
What is the femoral site?
Inner aspect of the upper thigh
What is the popliteal site?
Behind the knee
What is the dorsalis pedis site?
Top of the foot arch
What is the posterior tibial site?
Medial aspect of the ankle
What are the two most common sites for taking a pulse?
Radial, and apical
What is an apical pulse?
Ausculated with a stethoscope on the chest wall, pulse is found on the apex of the heart (bottom)
Characteristics of a pulse?
Pulse rate, rhythm, strength and intensity, bilateral presence
How is a pulse rate found?
Assessed in BPM, counted for 15/20/30/60 seconds
Tachycardia definition?
Pulses rate faster than normal
Bradycardia definition?
Pulse rate slower than usual
What does rhythm refer to?
Refers to the regularity of the pulse (spacing of the beats), the pattern of the heartbeat
What types of pulse rhythm are there?
Regular and irregular
What is an irregular pulse rhythm?
Arrhythmia, Usually caused by a defect in the electrical conduction pattern
What do you do when documenting a client with an irregular heartbeat?
Must be measured a full minute to determine average rate, document pulse rhythm as irregular (regular for a normal patient)
What are the two ways to describe a pulse’s strength and intensity?
Strong/bounding and weak/thready
Bilateral presence definition?
Pulses should have bilateral presence, found on both sides
BP definition?
Pressure/tension exerted on the arterial walls of blood pulsates through them
Systolic blood pressure definition? What is expected?
Pressure exerted on the arteries during the contraction phase of the heartbeat (100-149mm HG)
Diastolic blood pressure definition? What is expected?
Resting pressure on the arteries as the heart relaxes between contractions (60-90mm HG)
Hypotension definition?
When blood pressure drops below expected
Hypertension definitino?
High blood pressure (medical condition with multiple readings)
Equipment to measure BP?
Sphygmomanometer/BP cuff/cuff
Respiration definition?
Process of taking in O2 and expelling CO2 from lungs and respiratory tract
One is contained in one breath?
One inspiration and expiration
Dyspnea definition?
Difficult/laboured breathing
Apnea definition?
Absence of respiration?
Orthopnea definition?
Severe dyspnea in which breathing is very difficult in any position other than sitting erect/standing
What is a tachypnea resting respiratory rate?
RR>20 bpm
What is a bradypnea respiratory rate?
RR<12 bpm
Cheyne-Stokes respiration definition?
Periods of dyspnea followed by periods of apnea (dying patient)
Signs of respiratory distress?
Cyanosis, central asphyxiation, hyper/hypoventilation, rhythm of respiration and quality of respirationC
Cyanosis definition?
Dusky, bluish discolouration of the skin/lips/nail beds due to low O2 and high CO2 in the bloodstream
What is central cyanosis a sign of?
Respiratory distress
Central asphyxiation definition?
Lock of O2 getting into the body
What does it mean when the peripheral heart is not pumping properly?
Respiratory distress
Hyperventilation definition?
Increased respiratory rate (related to shallow breaths)
Hypoventilation definition?
Decrease in respiratory rate and depth (related to shallow breaths, but with its depth
Rhythm respiration should be…
Regular
What are the two qualities of respiration?
Shallow/deep
