Chapter 30: Health Assessment and Physical Examination

Health Assessment and Physical Examination details the foundational principles and techniques of health assessment and physical examination within nursing practice, emphasizing the critical role of data collection in forming clinical judgments and individualized care plans. It begins by outlining the purpose of physical examination, distinguishing between comprehensive and focused assessments, and stressing the importance of cultural sensitivity and infection control, including standard precautions and latex allergy management. The text describes the four primary assessment techniques—inspection, palpation, percussion, and auscultation—and how to apply them across the life span, from pediatric to geriatric populations. A systematic head-to-toe approach is presented, starting with a general survey of appearance, behavior, and vital signs. The integumentary assessment covers the evaluation of skin color variations (such as cyanosis, jaundice, and erythema), moisture, temperature, turgor, pitting edema, and lesion characteristics using the ABCDE rule for melanoma. Head and neck examinations include visual acuity testing with Snellen charts, assessment of extraocular movements and PERRLA, otoscopic inspection of the ear, and palpation of the thyroid gland and lymph nodes. The respiratory section details anatomical landmarks for auscultating vesicular, bronchovesicular, and bronchial breath sounds, as well as identifying adventitious sounds like crackles, rhonchi, and wheezes. Cardiac assessment explains the cardiac cycle, heart sounds (S1 and S2), the point of maximal impulse (PMI), and the detection of murmurs, while vascular evaluation includes blood pressure, carotid bruits, jugular vein distention, and peripheral pulse grading. The abdominal examination modifies the sequence to inspection, auscultation, and then palpation to correctly assess bowel motility and screen for distention or masses. Musculoskeletal assessment focuses on range of motion (ROM), muscle strength grading, and spinal alignment checks for kyphosis, lordosis, and scoliosis. Finally, the neurological assessment encompasses mental status evaluation using tools like the Mini-Mental State Examination, the Glasgow Coma Scale for level of consciousness, testing of the twelve cranial nerves, sensory dermatome evaluation, and reflex testing.
