Lesson 14. Mastering the Essentials: Techniques and Tools for Physical Examination

Jaundice may manifest as

yellowish tint to the skin and sclera, hinting at liver dysfunction

A fruity, acetone-like breath may suggest

diabetic ketoacidosis

limping gait could signify

musculoskeletal or neurological compromise.

Ulnar edge of hand is sensitive to

vibrations

Dorsal side of hand is

attuned to temperature variations

Palpation can detect

tenderness, organ enlargement, muscle rigidity, or the presence of masses.

Firm, nodular liver on palpation might indicate

cirrhosis

soft, pulsatile abdominal mass could suggest

aortic aneurysm

Percussion

striking the body's surface to produce sound waves and vibrations that travel through the tissues

Tapping on the thorax can distinguish air-filled lungs _____ from fluid-filled or consolidated lungs ____

resonant; dull

In a patient with pneumonia, the change from resonance to dullness over a lung field often pinpoints the infection's

location

A hyperresonant sound on one side might indicate a

pneumothorax

Pneumothorax

air has escaped into the pleural space, collapsing the lung.

‘shifting dullness’ technique

change in sound guides the identification of fluid accumulation in the abdomen

Auscultation

act of listening to the internal sounds of the body, primarily with a stethoscope

Cardiac auscultation

helps assess the timing and quality of heart sounds

Extra sounds such as S3 or S4 may hint at

heart failure or stiffness of the ventricular wall

Murmurs may suggest

valvular disease—perhaps aortic stenosis or mitral regurgitation

Irregular rhythms could point to

atrial fibrillation

the presence of crackles signifies possible

pulmonary edema

Stethoscope

used to listen to the heart, lungs, bowel sounds, and blood flow

Doppler stethoscope

used with patient’s whose pulses are faint or undetectable—as in patients with peripheral artery disease as well as monitoring fetal well-being in obstetrics

ophthalmoscope

clinicians to peer into the retina, optic disc, and blood vessels of the eye

ophthalmoscope provides early glimpses into systemic diseases such as

hypertension, diabetes, and neurological conditions

otoscope

facilitates ear examinations, illuminating the ear canal and tympanic membrane to detect infections or perforations

Otoscope is enhanced by

tympanometer

Tympanometer

assessing middle ear pressure helps identify effusions, preserving auditory health in children and adults alike.

Nasal speculum aid in

discerning allergic rhinitis, sinusitis, or structural deviations such as a deviated septum

Tuning forks-auditory

aids in distinguishing conductive from sensorineural hearing loss through the Rinne and Weber tests

Tuning forks- neurology

assesses peripheral nerve integrity, vibrating at a consistent frequency

Monofilament test

tool for testing sensory nerve function, especially in diabetic neuropathy risk assessment

Transillumination

differentiates solid from cystic masses, illuminating fluid-filled cavities through body structures

Vaginal Speculum

visualization of the vaginal walls and cervix for Pap smears, exams, and detection of cervical lesions

Wood’s lamp

emits ultraviolet light, identifying dermatoses that fluoresce. It excels in diagnosing fungal infections, pigment disorders, and bacterial conditions

Goniometer

instrument used to measure join tangles, assessing range of motion

Calipers

device used for measuring skinfold thickness, aiding in body fat assessment

Snellen chart

Alphabet chart used to evaluate visual acuity at a distance

Inspection

visual and often olfactory evaluation of a patient to detect physical cues like skin color or posture

Fetoscope

stethoscope variant for listening to fetal heart tones via the mother’s abdomen

Reflex hammer

tool used to evaluate neuromuscular response via deep tendon reflex testing

Tape measure

instrument used to measure dimensions like limb circumference or abdominal girth
