Study Notes
Health History
- All assessments involve collecting two types of data: objective (observed and verifiable) and subjective (provided by the patient and verified only by the patient)
- Objective data includes findings such as a red, swollen arm in a patient with arm pain
- Subjective data includes statements such as "My head hurts" or "I have trouble sleeping"
Interviewing Tips
- Create an environment where the patient feels comfortable to ensure effective communication
- Use quiet, private settings and avoid using medical jargon
- Choose terms carefully and avoid using complex medical terms
- Verify abnormal vital sign values to ensure accuracy
- Normal readings vary with age (e.g., temperature decreases with age, and respiratory rate can increase with age)
Physical Assessment Techniques
- Four techniques are used: inspection, palpation, percussion, and auscultation
- Techniques are used in this sequence except for abdominal assessments
- Inspection involves using vision, smell, and hearing to assess normal conditions and deviations
Lesion Distribution and Configurations
- Lesion distribution can be:
- Generalized (all over the body)
- Regionalized (limited to one area of the body)
- Localized (sharply limited to a specific area)
- Scattered (dispersed either densely or widely)
- Exposed areas (limited to areas exposed to air or sun)
- Intertriginous (limited to areas where skin comes into contact with itself)
- Lesion configurations can be:
- Discrete (individual lesions are separate and distinct)
- Grouped (lesions are clustered together)
- Confluent (lesions merge so that discrete lesions are not visible)
- Dermatomal (lesions form a line or an arch and follow a dermatome)
Wound Stages
- Stage I: Intact skin that doesn't blanch, may differ in color from surrounding area, and is usually over a bony prominence
- Stage II: Superficial partial-thickness wound with a shallow, open ulcer without slough and with a red and pink wound bed
Eye Anatomy
- The eye has three layers of tissue: outermost, middle, and innermost
- Outermost layer includes:
- Cornea
- Sclera
- Middle layer includes:
- Choroid
- Ciliary body
- Iris
- Innermost layer is the retina, which receives visual stimuli and sends them to the brain
- Other structures include:
- Pupil
- Anterior chamber (filled with aqueous humor)
- Posterior chamber (filled with aqueous humor)
- Schlemm's canal
- Vitreous humor
- Optic nerve
- Central retinal artery and vein
