Exam 1 Flashcards
What are the 6 vital signs?
Blood pressure, O2 saturation, Respiration, Temperature, Pulse, Pain.
Why are vital signs signifiant?
It regulates the organs and the body.
Provides data on the overall condition of the body.
Provides changes on the baseline against which you can measure.
When to asses?
Admission, routine visits, according to patient or policyholder, patients complaints or changes, when admin certain medication, procedures, If there is a major change in the VS.
Core temperature
Is the temperature of the deeper tissues and structures.
Thermoregulation.
The regulation of the body’s temperature controlled by the hypothalamus.
Normal body temperature:
98.6 F
Normal oral temperature range:
97.6-99.6
Normal tympanic temp range:
97.6-99.6 F
Normal rectal range
98.6-100.6 F
Normal axillary temp range:
96.6-98F
Hypothermia
When the body’s temperature falls below 95F.
Blood Pressure
Measurement of pressure or tension of blood pushing against the walls of the arteries in the vascular system.
Stoke volume
The amount of blood ejected in one contraction
Cardiac output
The amount of blood pumped from the heart in a full minute.
Pulse pressure
The difference between systolic and diastolic BP
Normal BP
Less than 120/80
Hypotension
Suddenly falls 20-30 mmHg
Falls below 100/60
Stage 1 hypertension BP
130-139/80-89
Stage 2 Hypertension
Greater than 140/90
Sphygmomanometer
BP cuff
Define auscultatory
The period which sound indicating true systolic pressure fade away and comes back in a weaker point.
How to avoid auscultatory gap?
Making sure to palpate while the cuff pressure is rapidly increased.
Define pulse
A rhythmic pulsing throbbing or the artery as blood goes through it.
Where is the apical pulse located? Why would you want to take an apical pulse?
Over the apex of the heart. 3-4 inches left of the sternum in the 5th intercostal space. Most accurate pulse. Atrial and ventricles information we ausculte (listen with stethoscope.) Full minute.
Define pulse deficit
pulse deficit is the difference between the systolic and diastolic rate.
3 factors of taking pulse
Rhytym, How many BPM, Strength (volume)
Pulse sites
Temporal: over the temporal bone. Carotid: side of the neck. Brachial: ante cubical Radial: wrist parallel to the thumb Femoral: Groin Popliteal: begins the knee Posterior tibialis: side of the ankle Dorsalis pedis: on top of the foot
Bradycardia
A pulse less than 60 bpm
Tachycardia
Greater than 100 bpm
Normal pulse range
60-100 bpm
Pulse range depending on age (bpm)
Newborns: 120-160
1-2: 90-120
3-18: 80-100
Adults: 60-100
Volume of pulse
3+ is bounding pulse is very full pulse, easy to feel, and bounding.
2+ is normal and easily directed but you can obliterate.
1+ pulse is weak and will obliterate with one
Thready very faint- very hard to feel.
0 absent- no pulse.
What is capillary refill time?
Indication if there is an adequate circulation. This is tested under the nail bed.
Normal: less than 3 secs on adults and children.
Within 5 secs in the elderly.
Respiration
Is interchange of oxygen and carbon dioxide.
Bradypnea
Respiratory rate below 12/minute
Tachypnea
Respiratory rate exceeds 20 respiration’s/minute
Describe external respiration
Breathe into the lungs and then the lung exchange gas with the heart.
Internal respiration
Exchange o2 between the tissues and the blood
Normal respiration range
12-20- Adult 30-60 newborn 20-40 infants 20-30 children 14-25 adolescence
