👀 Chapter 8 – Cultivating Your Senses in Physical Assessment
1. 🔎 Four Core Assessment Techniques
Order (usually):
- 👁️ Inspection
- ✋ Palpation
- 👂 Percussion
- 🎧 Auscultation
2. 🧩 Core Assessment Techniques
A. Inspection (👀)
- Starts immediately at first interaction.
- Needs: good lighting, adequate exposure, patient comfort.
B. Palpation (✋)
Purpose: Touch → assess:
- Texture, temperature, moisture
- Organ size, location, consistency
- Swelling, vibration, pulsations
- Tenderness or pain
Hand Techniques:
- Fingertips → texture, swelling, lumps
- Finger + thumb (grasping action) → organ/mass shape, position
- Dorsa (back of hand) → temperature
- Ulnar surface (or base of fingers) → vibration
Approach:
- Start light → progress deep
- Use bimanual palpation for deep organs (kidneys, uterus)
- Warm hands, be calm, systematic
- Palpate tender areas last
- Skin turgor check (not abdomen)
C. Percussion (👂 + 👋)
Purpose: Tapping → vibrations & sounds for:
- Organ location/size
- Density (air, fluid, solid)
- Reflexes (with hammer)
👉 Obese patients = strike stronger.
Technique: 2 quick taps.
Percussion Notes (Table 8.1):
Note | Amplitude | Pitch | Quality | Duration | Example |
Resonant | Medium-loud | Low | Clear, hollow | Moderate | Normal lung |
Hyperresonant | Louder | Lower | Booming | Longer | Child lung, emphysema |
Tympany | Loud | High | Musical, drumlike | Longest | Stomach, intestine |
Dull | Soft | High | Muffled thud | Short | Liver, spleen |
D. Auscultation (🎧)
- Listening with a stethoscope (filters, not amplifies).
- Diaphragm: high-pitched (heart, breath, bowel).
- Bell: low-pitched (murmurs, extra heart sounds).
👉 Too much chest hair? Wet it.
Best Practices:
- Quiet room, warm stethoscope, no clothing barrier.
- Minimize artifacts (hair rubbing, jewelry, tubing noise).
- Focus on one sound at a time.
- Know expected sounds per area.
- Never listen through clothing.
3. 🏥 Clinical Environment & Equipment
Room Setup:
- Warm, quiet, private, well-lit
- Exam table accessible from both sides
- Bedside table for organized equipment
Basic Equipment:
- Scale w/ height rod
- BP cuff, thermometer, pulse ox
- Stethoscope
- Otoscope/ophthalmoscope
- Reflex hammer, tuning fork, tape measure
- Gloves, lube, alcohol wipes, sanitizer
- Speculums, cotton balls, vision screener
4. 🧼 Infection Control & Safety
A. Clean Field
- Clean stethoscope & tools before/after each pt.
- Separate clean vs. used equipment.
B. Hand Hygiene ✋💦
- #1 way to prevent infection.
- Do it:
- Before & after pt contact
- After body fluid exposure
- After removing gloves
- Alcohol rub → if hands not soiled.
- Soap & water → for C. difficile or norovirus.
C. Precautions (Table 8.3)
Type | Protection Needed | Example |
Standard | Hand hygiene, PPE as needed | All patients |
Contact | Gown + gloves | MRSA, C. diff |
Droplet | Surgical mask | Influenza, pertussis |
Airborne | N95 + gown + gloves + eyewear (if needed) | TB, measles |
5. 👶👴 Developmental Considerations
Group | Approach & Techniques |
Infant 👶 | Use caregiver; least invasive first; warm hands/voice; distract with toys |
Toddler 🚼 | On caregiver’s lap; firm but gentle; praise; invasive steps last |
Preschool 🎨 | Offer choices; let them handle tools; simple explanations; play |
School-age 📚 | Head-to-toe; explain procedures; involve; modesty |
Adolescent 🙍♂️ | Alone; privacy; respect body image; encourage healthy habits |
Older Adult 👴 | Pace exam; minimize position changes; use touch; rest periods |
Sick Patient 🤒 | Focused assessment first; full exam later |
6. ✅ Key Takeaways
- Master IPPA (Inspection, Palpation, Percussion, Auscultation).
- Cleanliness & infection control = non-negotiable.
- Adapt exam to age, condition, comfort.
- Communication + reassurance = better trust & accuracy.
💡 Extra Q/A Notes
- HIV patient: Hand wash + gloves. Gown/face shield not routine. No double gloves needed.
- Respiratory disease: Educate patient, staff, visitors.
- Interviewing: Psychotic pt → don’t close the door.
- Positioning:
- Too old/tired → Supine
- Can’t breathe → Semi-Fowler’s
