Block 1 Objectives part 1 Flashcards
otoscope
provides illumination for examining the external auditory canal and the tympanic membrane.
ophthalmoscope
has system of lenses and mirrors to visualize the interior structures of the eye.
ophthalmoscope apertures
large aperture – (most commonly used) produces a large round beam
small aperture – for small pupils
red free filter – produces green beam for examination of the optic disk for pale appearance and vessel changes. Recognition of retinal hemorrhages (blood appears black)
slit – for anterior eye and elevation of lenses
Grid – Estimation of the size of fundal lesions.
sphygmomanometer
a device used to manually measure blood pressure with the use of a stethoscope. The inflatable bladder restricts blood flow, measurements of pressure are recorded when blood flow is just starting and when it ceases to be unimpeded.
thermometers
used to measure body temperature which can be a clue to a pt’s illness/current state
oral temp
oral – placed under the tounge (98.6) (abnormal >100)
rectal temp
rectal – commonly used for infants for accurate reading. (99.6) (abnormal >101)
axillary temp
axillary – held between body and arm. (97.6)
tympanic temp
tympanic – used in the ear – tympanic membrane shares blood supply with hypothalamus. (99.6) (abnormal >101)
stethoscope
can be acoustic, magnetic, or electronic
b. Bell – Low pitched sounds – light pressure (harder to hear sounds)
c. Used to listen to heart and adnominal sounds
Diaphragm – high pitched sounds – firm pressure
Snellen visual acuity
a. Used for screening and examination of far vision for literate, English, verbal adults and school aged children
b. Recorded as a fraction – numerator = # of feet between chart and pt. and denominator = distance from which a normal person can read the lettering
Rosenbaum visual acuity charts
used to test near vision at distance of 14 in.
512 tuning fork
auditory evaluation via estimating hearing loss in the range of normal speech. This is the lowest intensity of sounds at which an auditory stimulus can be heard.
128 tuning fork
vibratory sensation applied to bony prominence the patient should feel the vibration/tingling.
percussion hammer
used to test deep tendon reflexes, tap should be brisk and direct
tape measure
used to determine circumference, length, diameter. Pull tape tightly without causing depression in skin.
transilluminator
strong light source with narrow beam directed into body cavity to differentiate between various media present in that cavity (air, fluid, tissue). Place beam of light directly against area to observe the presence or absence of illumination and any irregularities.
palmar surface palpation
used for distinguishing size and texture. Any examination that requires fine detail/texture should be done with palmar surface. More nerve endings on this portion of the hand.
ulnar surface palpation
used for detection of vibration
dorsal surface palpation
used for detection of temperature. better than palmar surface because your own body heat does not interfere.
Diaphragm sounds
best for high-pitched sounds (heart sounds and abdominal/bowel sounds)
with firm pressure skin converts bell to a diaphragm end piece
Bell Sounds
best for low-pitched sounds when light pressure is used
bruits -
turbulent blood flow through artery & heart
murmurs
turbulent blood flow through heart valve)
normal pulse
Normal: 60-100 beats per minute
resting pulse
number of heart beats per minute while at complete rest; generally 60-100 beats per minute; average 70 bpm; this can vary widely based on general health and fitness, age, underlying medical conditions
Tachycardia pulse
pulse rate>100 beats per minute
Bradycardia: pulse
rate<60 beats per minute
tachycardia
If oxygen demand or metabolic activity increases, blood volume decreases, the body is working, or the sympathetic nervous system is activated (stress, certain drugs), this can induce tachycardia
bradycardia
While the body is at rest there is less oxygen demand and metabolic activity, so the pulse rate decreases. Parasympathetic stimulation and certain drugs can decrease the heart rate significantly below a normal resting heart rate.
Korotkoff sounds. (Seidel/Mosby pg 54-55)
Low-pitched sounds produced by turbulence of blood flow in the artery
ausculatory gap
Korotkoff sounds may disappear 10-15 mmHg below first systolic reading = this is normal and called the ausculatory gap
First and Second Korotkoff sounds
First two audible consecutive beats indicate systolic pressure reading and beginning of Korotkoff sounds
when the Korotkoff sounds disappear, this is the second diastolic sound
Guarding
: protective behavior, distorted posture, reluctance to be moved
Facial mask of pain:
lackluster eyes, wrinkled forehead, tightly closed or opened eyes, fixed or scattered movement
Vocalizations:
grunting, groaning, crying, talkative patient becomes quiet
Body movements
:head rocking, pacing or rubbing; an inability to keep the hands still
Changes in vital signs: Pain
blood pressure, pulse, respiratory rate and depth, with acute onset of pain. Fewer changes in vital signs are found in patients with persistent pain or after they adapt to acute pain.
Premature Infant Pain Profile (PIPP) for 28-40 wks gestation
physiology(heart rate, O2 saturation)
o pain behaviors (brow bulge, eye squeeze, nasolabial furrow)
Neonatal Infant Pain Scale (0-6wks)
Facial expression, cry, breathing pattern, arm and leg movements, sate of arousal observed/scored
CRIES Scale
(Crying, Requires oxygen to keep saturation above 95, Increased vital signs, Expression, Sleeplessness.
Score: crying, expression, sleeplessness, O2 sat, heart rate, BP
Older Adults non-verbal pain scoring:
“Nonverbal Checklist for Pain Scoring”. Score 0 if behavior not observed, score 1 if the behavior was observed. Score ranges 0-5.
Vocal Complaints: verbal expression of pain using words such as “ouch” or “that hurts”.
Bracing: clutching or holding onto siderails, bed, tray table, or affected area during movement
Restlessness: constant or intermittent shifting of position, rocking.
Rubbing: massaging affected area
Facial Grimace and Winces: furrowed brow, narrowed eyes, tightened lips, dropped jaw, clenched teeth, distorted expression
Vocal Complaints: nonverbal expression of pain demonstrated by moans, groans, grunts, cries, gasps, sighs
Facies:
expression or appearance of the face and features of the head and neck indicating a clinical
condition or syndrome
certain conditions impart a “classic” physical appearance to the face indicating an underlying disease or syndrome. In GA, facies can be used to diagnose condition or syndrome (most often an endocrine disorder, but could be congenital or infectious disease). (PKM lecture on GA)
Hyperthyroid disease
exopthalamos (prominent eyes, lid retraction)
Sclera
The outer layer of the posterior eye, which is a dense, avascular structure. It supports the internal structure of the eye. It also encases the Optic nerve
optic nerve
Optic nerve, which passes through the optic foramen along with the ophthalmic artery and vein, sends signals to the CNS.
cornea
The Cornea is the outer layer of the anterior eye. It is continuous with the Sclera. It is optically clear, has rich sensory innervations, and is also avascular.
Uveal Tract
The Uveal tract consists of the Iris, Ciliary body, and Choroids. T
Iris
(the color of the eye) is a circular, contractile muscular disc that controls the amount of light that is able to reach teh retina.
pupil
The central aperture of the iris is the pupil, which light travels to the retina.
ciliary body
The ciliary body produces the aqueous humor (fluid that circulates between the lens and cornea) and contains the muscles that control accommodation.
Choroid
The Choroid is a pigmented, richly vascular layer that supplies oxygen to the outer layer of the retina.
lens
The Lens is a biconvex, transparent structure located behind the iris. It is supported by fibers that come from the ciliary body. It is highly elastic, and contraction or relaxation of the ciliary body changes its thickness, allowing images of various distances to be focused by the retina.
Retina
The Retina is the sensory network of the eye. It transforms light impulses into electrical impulses, which are transmitted through the optic nerve, optic tract and optic radiation to the visual cortex of the brain, the cerebral cortex. Other landmarks of the retina include the optic disc, where the optic nerve originates, together with the central retinal artery and vein. The Macula, or fovea is the site of central vision.
eyelid
The eyelid is composed of skin, striated muscle, the tarsal plate and conjunctivae. Meibomian glands provide oils to the tear film. The tarsus provides a skeleton to the lid. The eyelid distributes tears over the surface of the eye, limits the amount of lights entering it, and protects the eye from foreign bodies.
The Conjunctiva
is a clear, thin mucous membrane. The palpebral conjunctiva is the part of the conjunctiva that coats the inside of the eyelid. The bulbar conjunctiva is the part that covers the outer surface of the eye. The conjunctiva should be observed for erythema and exudate.
Eye Muscles
superior, inferior, medial, and lateral rectus muscles.
superior and inferior oblique muscles, which allow you to move your eyes at an angle.
The Lacrimal Gland
is located in the temporal region of the superior eyelid and is responsible for tear production.
Head Bones
made up of 7 bones: frontalx2, parietalx2, occipital, temporalx2;
Face Bones
mandible, maxilla, zygomatic, sphenoid, lacrimal, and nasal bones.
