7. Vital Signs and Patient Assessment Flashcards
measurement of temperature, pulse rate, respiratory rate, and blood pressure
Vital Signs
4 Vital Signs
- Temperature
- Pulse
- Respiration
- Blood Pressure
may be obtained by the oral, rectal, axillary, tympanic, and temporal artery routes
Temperature
Temperature is ____ in the morning and ____ in the evening
lowest (am),
highest (pm)
is a sign of increased body metabolism (energy use), usually in response to an infectious process
fever (pyrexia or hyperthermia)
not appropriate when the patient has recently has a hot or cold beverage, is receiving oxygen, or is breathing through the mouth
Oral Temperature
temperature site that is accurate and faster
Rectal Temperature
temperature site that is slower and least accurate
Axillary Temperature
temperature site that is reliable and accurate
Tympanic Temperature
the palpable rhythmic throbbing caused by the alternating expansion and contraction of an artery as a wave of blood passes through it
Pulse
occurs when the heart rate is greater than 100 BPM
Tachycardia (abnormal radial pulse)
Pulse sites
- Temporal
- Carotid
- Brachial
- Radial
- Femoral
- Popliteal
- Posterior tibial
- Dorsalis pedis
if the radial pulse is weak or difficult to count, you can use the _____,
place your fingers just below the angle of the mandible
Carotid artery
easily accessible pulse site
Carotid Artery
particularly important if a patient loses consciousness
Carotid Artery
if the pulse is not palpable at this site, the heart is not beating effectively and emergency measures are necessary
Carotid Artery
a measurement taken by listening to the heartbeat through a stethoscope that is placed over the apex of the heart
Apical Pulse
taken over the instep of the foot pulse site
Dorsalis pedis Pulse
this measurement is significant if the peripheral circulation is compromised
Dorsalis pedis Pulse
when a patient shows evidence of respiratory distress, a respiratory rate will help in making an assessment
Respiration (rpm)
number of inhalations per minute
Respiration (rpm)
slow breathing with fewer than 12 breaths per minute
Bradypnea
rapid breathing in excess of 20 breaths per minute
Tachypnea
difficulty breathing (DOF), abnormal respiration
Dyspnea
patients in shock or with significant blood loss have marked ______ in pulse rate and in rapid, shallow breathing as the body attempts to supply oxygen to the tissues by increasing the speed of circulation
increase
critical condition brought by a sudden drop in blood flow of the body
Shock
the force of circulating blood on the walls of the arteries
Blood Pressure (mmHg)
measured when the heart beats, when blood pressure is at its highest, contraction
Systolic
measured between heart beats, when blood pressure is at its lowest, relaxation
Diastolic
abnormally high blood pressure
Hypertension
abnormally low blood pressure
Hypotension
results in a potentially life-threatening condition called shock
Hypotension
pressure exerted when blood is ejected into arteries
Systolic Blood Pressure
pressure blood exerts within arteries between heartbeats
Diastolic Blood Pressure
normal systolic blood pressure is
120 mmHg or below
normal diastolic blood pressure is
80 mmHg or below
