Examination Techniques and Equipment Overview This chapter covers essential physical examination techniques, equipment, patient positioning, infection control, and modifications for patients with disabilities to ensure thorough and safe assessments. Basic Examination Techniques and Equipment Overview of fundamental methods and tools used during physical exams. Techniques include inspection, palpation, percussion, and auscultation. Equipment needed: stethoscope, ophthalmoscope, otoscope, blood pressure cuff, centimeter ruler, tape measure, reflex hammer, tuning forks, penlight, vision chart. Equipment quality, warranty, and features should be evaluated before purchase. Patient positions include seated, supine, prone, dorsal recumbent, lateral recumbent, and lithotomy, each suited for specific exam parts. Draping maintains modesty and exposes only necessary areas. Infection Prevention and Safety Measures Overview of precautions to prevent infection transmission. Standard Precautions: hand hygiene, PPE, respiratory hygiene, safe injection, equipment handling. Use soap and water when hands are visibly soiled; alcohol-based hand rub preferred otherwise. PPE includes gloves, gowns, masks, eye protection; removed after patient care. Safe injection practices: aseptic technique, single-use syringes, proper disposal. Environmental cleaning: use EPA-registered disinfectants, follow manufacturer instructions. Respiratory etiquette: cover coughs/sneezes, use tissues, wear masks if needed. Transmission-Based Precautions: additional measures for known or suspected infectious diseases. Latex Allergy and Protective Strategies Overview of latex allergy types and prevention. Types: irritant contact dermatitis, Type IV delayed hypersensitivity, Type I systemic allergic reactions. Symptoms range from dry skin to anaphylaxis. Healthcare workers at risk due to glove exposure; sensitization occurs via skin or airborne particles. Recommendations: use non-latex or hypoallergenic gloves, wash hands after glove removal, avoid oil-based lotions, and educate about latex allergy.
Patients with multiple procedures are at higher risk of latex allergy. Patient Safety and Professional Protection Overview of measures to protect healthcare providers and patients. Follow Standard Precautions and PPE use. Minimize latex exposure. Use proper body mechanics and lifting devices. Protect against work-related injuries and infections. Patient Positions and Draping Techniques Overview of common patient positions and draping methods. Positions: seated, supine, prone, dorsal recumbent, lateral recumbent, lithotomy. Draping ensures modesty, exposes only necessary areas, and varies with position. Proper positioning facilitates specific examinations and patient comfort. Inspection as a Key Examination Step Overview of visual assessment during physical exam. Observe gait, stance, clothing, skin color, moisture, odor, emotional state, and body language. Inspection continues throughout the exam, providing ongoing data. Good lighting and exposure are essential. Recognize odors as clues to certain conditions, e.g., fruity smell in salicylate poisoning. Critical for initial assessment and ongoing observation. Palpation Techniques and Hand Usage Overview of tactile assessment methods. Use palmar surface for texture, size, mass, and structure. Ulnar surface detects vibration. Dorsal surface estimates temperature. Gentle, warm hands and short nails are recommended. Practice both light and deep palpation for comprehensive assessment. Percussion Methods and Common Errors Overview of producing and interpreting body sounds. Percussion involves striking to produce vibrations and tones.
Patients with urinary equipment should guide on catheter tubing and leg bag placement. Patients should inform when they are comfortable and balanced after transfers. Parties must be aware of jewelry, clothing, tubing, or equipment that could interfere with transfers. All involved should understand the best transfer method suited to the patient's disability, room space, and examination table. Know your physical limits; seek help to prevent injuries and falls. Patient Transfer Techniques Various transfer methods ensure safe movement of patients with mobility impairments. Pivot Transfer: Stand in front, grasp patient around back and under arms, raise to vertical, pivot to table; low tables or hydraulic tables may be needed. Cradle Transfer: Bending or squatting, support knees and back, then stand and carry patient. Two-Person Transfer: Two assistants coordinate to lift patient from wheelchair to table; stronger person supports upper body, and specific methods depend on patient arm position. Equipment: Use slide boards, adjustable high-low tables, or wider tables to facilitate transfers. Proper technique and teamwork are essential to prevent injury. Communication with Sensory-Impaired Patients Effective communication strategies are vital for patients with hearing, speech, or visual impairments. Discuss preferred communication methods (sign language, word boards, typing, assistive devices). Use educational materials like Braille, audiotapes, or models. For visually impaired: identify yourself, inform when leaving, respect guide animals, and describe surroundings verbally. For hearing or speech impairments: provide auxiliary aids, choose communication mode, and position interpreters appropriately. Speak directly to the patient, not the interpreter, and ensure effective use of interpreters (family members are inappropriate). Special Considerations for Spinal Cord Injury Patients Patients with spinal injuries require attention to bowel, bladder, and autonomic responses during examinations. Bowel and bladder routines may affect examinations; indwelling catheters usually remain in place.
Tactile stimulation during exams can trigger bowel movements or incontinence. Autonomic Dysreflexia: life-threatening condition with symptoms like high blood pressure, sweating, nausea; caused by stimulation below injury level. Remove stimuli, sit upright, loosen tight clothing, and monitor blood pressure; stop exam if symptoms persist. Manage hypersensitivity and spasms with lubrication, support, and safety measures. Never leave patients alone during spasms; maintain physical contact for safety. Equipment for Measurement and Examination Various devices assist in accurate assessment and diagnosis. Weight and Height Devices: Manual and electronic scales, infant scales, and measuring boards; calibration and hygiene are critical. Thermometers: Digital, infrared, tympanic; select based on patient age and condition. Stethoscopes: Acoustic, magnetic, electronic; ensure quality, proper fit, and disinfection. Sphygmomanometers: Manual and electronic; measure blood pressure, with manual preferred for accuracy. Pulse Oximeters: Measure oxygen saturation; require good blood flow and strong pulse. Dopplers: Detect blood flow, fetal heart, and vessel patency; useful for weak or difficult- to-hear sounds. Portable Ultrasound: Bedside imaging for organs, fluid, and blood flow; requires trained operation. Fetal Monitoring: Fetoscopes, Leff scope, Doppler for fetal heart rate detection. Ophthalmoscopes: Visualize internal eye structures; PanOptic offers a larger view. StrabismoScope: Detects eye misalignment in children. Photoscreening: Detects amblyopia and strabismus in children. Visual Acuity Charts: Snellen, Sloan, HOTV, LEA symbols; used for far and near vision testing. Amsler Grid: Monitors central vision for macular degeneration. Otoscopes: Examine ears and nasal passages; digital models available. Tympanometers: Assess middle ear function via compliance and pressure. Tuning Forks: Test hearing and vibratory sensation; frequencies 500-1000 Hz for hearing. Reflex and Neurologic Hammers: Test deep tendon reflexes and sensory perception. Tape Measure: Measure circumference, length, and diameter accurately. Transilluminators: Detect fluid or masses in cavities, e.g., hydrocele. Vaginal Specula: Visualize vaginal canal and cervix; various sizes and types. Goniometers: Measure joint angles; digital models provide precise readings. Wood’s Lamp: Detect fungal infections via fluorescence. Monofilament: Test protective sensation in feet; bends at 10 g pressure. Dermatoscope: Examine pigmented skin lesions; requires training. Scoliometer: Screen for scoliosis by measuring spinal rotation; positive if ≥7 degrees.
