A general physical examination is a structured head-to-toe evaluation designed to gather baseline health data and detect objective signs of disease. The primary purpose is to identify clinical abnormalities early, evaluate the patient's overall functional capacity, and monitor changes in their clinical condition over time. Nurses perform this assessment upon admission, during routine shift changes, and whenever a patient reports new symptoms. It establishes a clinical baseline that guides subsequent nursing interventions and medical treatments.
Creating a suitable environment ensures patient comfort, privacy, and accuracy of findings. The examination room or bedside area must be warm, well-lit, and quiet to allow proper inspection and auscultation.
Conducting a safe physical examination requires specific tools and strict adherence to infection prevention protocols. Standard precautions protect both the nurse and the patient from cross-contamination.
| Equipment | Primary Clinical Use |
|---|---|
| Stethoscope | Auscultating heart, lung, and bowel sounds |
| Sphygmomanometer | Measuring blood pressure |
| Penlight | Inspecting the oral cavity and pupillary light reflex |
| Thermometer | Assessing core body temperature |
Hand hygiene must be performed before and after every patient contact, and equipment like stethoscopes must be disinfected between uses.
The general survey begins the exact moment the nurse meets the patient, forming an overall impression of health status. This phase involves observing physical appearance, body structure, mobility, and behavior without using specialized instruments.
Vital signs are critical quantitative indicators of physiological function. They include temperature, pulse rate, respiratory rate, blood pressure, and oxygen saturation. These measurements must be taken accurately because sudden deviations often serve as the earliest warning signs of clinical deterioration. Pain is frequently evaluated alongside vital signs as the fifth vital sign, providing a more comprehensive view of patient comfort and stress response.
A systematic head-to-toe assessment ensures no body system is overlooked. The standard physical examination sequence follows four core techniques: inspection, palpation, percussion, and auscultation. (Note: For the abdomen, auscultation is performed before palpation and percussion to avoid altering bowel sounds.)
The assessment starts at the head, checking the scalp, eyes, ears, nose, and mouth, then moves downward to the neck, chest, abdomen, extremities, and skin.
Accurate documentation creates a permanent legal record of the patient's health status and ensures continuity of care among healthcare team members. Findings must be recorded objectively, avoiding vague terms like 'normal' or 'fine.' Instead, describe specific observations such as 'clear breath sounds bilaterally' or 'skin warm and dry.' Any abnormal findings must be reported immediately to the attending physician or senior nurse in charge.
