Unit 1 Flashcards
Accommodation
the ability to constrict when looking at a near object and dilate when looking at an object in the distance
Audiometry
measures hearing acuity at various sound frequencies
Auscultation
listening to body sounds
A body systems approach
means assessing the client according to the functional systems of the body.
Capillary refill time
the time it takes blood to resume flowing in the base of the nail beds
Cerumen
a yellowish-brown, waxy secretion produced by glands within the ear
consensual response
a brisk, equal, and simultaneous constriction of both pupils when one eye and then the other is stimulated with light
drape
a sheet of soft cloth or paper
Edema
is excessive fluid within tissue and signifies abnormal fluid distribution
Extraocular movements
which are eye movements controlled by several pairs of eye muscles
head-to-toe approach
means assessing the client from the top of the head down to the feet
hearing acuity
the ability to hear and discriminate sound
Inspection
purposeful observation
Jaeger chart
a visual assessment tool with small print or newsprint with varying sizes of letters for near vision
mental status assessment
a technique for determining the level of a client’s cognitive functioning
ophthalmoscope
An instrument used to examine structures within the eye
otoscope
An instrument used to examine the tympanic membrane, or eardrum.
Palpation
involves lightly touching or applying pressure to the body
Percussion
is striking or tapping a part of the client’s body with the fingertips to produce vibratory sounds
PERRLA
pupils equally round and reactive to light and accommodation
physical assessment
a systematic examination of body structures
Rinne test
an assessment technique for comparing air versus bone conduction of sound
Smelling acuity
the ability to smell and identify odors
Snellen eye chart
a tool for assessing far vision
Turgor
the resiliency of the skin; fullness or lack thereof
Visual acuity
the ability to see both far and near
visual field examination
is the assessment of peripheral vision and continuity in the visual field
Weber test
an assessment technique for determining equality or disparity of bone-conducted sound
afebrile
no fever
afterload
the force against which the heart pumps when ejecting blood
antipyretics
such as aspirin, acetaminophen, and ibuprofen directly lower body temperature
apical heart rate
the number of ventricular contractions per minute
apical–radial rate
the number of sounds heard at the heart’s apex and the rate of the radial pulse during the same period
Apnea
the absence of breathing
arrhythmia or dysrhythmia
an irregular pattern of heartbeats
auscultatory gap
a period during which sound disappears during BP
automated monitoring devices
equipment that allows for the simultaneous collection of multiple data
baroreceptors
sensory nerves in the walls of large arteries. A baroreceptor’s function is to maintain arterial pressure
Blood pressure
is the force the blood exerts within the arteries
Bradycardia
less than 60 bpm
Bradypnea
a slower-than-normal respiratory rate at rest
brown adipose tissue (BAT).
contains brown adipocytes filled with mitochondria that raise body temperature by increasing metabolism. BAT is usually located near the neck, the chest, and upper back
Cardiac output
the volume of blood ejected from the left ventricle per minute
centigrade scale
a scale that uses 0°C as the temperature at which water freezes and 100°C as the point at which it boils
cerumen
ear wax
clinical thermometers
instruments used to measure body temperature
core temperature
warmth in deeper sites within the body like the brain and heart
diastolic pressure
pressure within the arterial system when the heart relaxes and fills with blood
Doppler stethoscope
helps detect sounds created by the velocity of blood moving through a blood vessel. The sounds of moving blood cells
drawdown effect
cooling of the ear when it comes in contact with the probe
Dyspnea
difficult or labored breathing
Fahrenheit scale
a scale that uses 32°F as the temperature at which water freezes and 212°F as the point at which it boils
febrile
a condition in which the temperature is elevated
fever
body temperature that exceeds 99.3°F
frenulum
structure that attaches the underneath surface of the tongue to the fleshy portion of the mouth
Hypertension
high blood pressure
Hyperthermia
excessively high core temperature describes a state in which the temperature exceeds 105.8°F
Hyperventilation
rapid or deep breathing or both
Hypotension
low blood pressure
hypothalamus
a structure within the brain that helps control various metabolic activities
hypothermia
a core body temperature less than 95°F
hypoventilation
diminished breathing
Korotkoff sounds
sounds that result from the vibrations of blood within the arterial wall or changes in blood flow
metabolic rate
use of calories for sustaining body functions
offsets
Amount of money returned to the hospital for saving money on patient care.
Orthopnea
breathing facilitated by sitting up or standing
Postural or orthostatic hypotension
is a temporary drop in blood pressure when rising from a reclining position after 3 to 5 minutes of rest
palpitation
awareness of one’s own heart contraction
piloerection
the contraction of arrector pili muscles in skin follicles
preload
the volume of blood that fills the heart and stretches the heart muscle fibers during its resting phase
