Mastering Health Assessment Techniques

Mastering Health Assessment Techniques

Health assessment lies at the core of nursing practice, giving valuable insight into a patient's wellbeing. By combining various techniques, you're able to compile a comprehensive understanding of a patient's current state and future needs. Here, we'll focus on five key components of health assessment: physical assessment techniques, vital signs evaluation, documentation, health history, and risk assessment.

Physical Assessment Techniques

Nurses employ four main techniques—observation, inspection, palpation, and percussion—sequentially (except during abdominal assessments). Observation includes noting facial expression, skin tones, and body movements. Inspection calls for visualizing the whole body, closely observing unusual marks or bruises. Palpation involves touching different parts of the body to gauge texture and consistency. Percussion evaluates resonance in organs like lungs.

Vital Signs Evaluation

This fundamental aspect of health assessment involves measuring a patient's heart rate, blood pressure, temperature, and respiratory rate. Recording normal values provides a solid starting point for comparison when illness or injury occurs.

Documentation

Accurately documenting findings ensures continuity of care and facilitates future reference. Documentation includes describing observations, measurements, patient responses, and conclusions reached in relation to the assessment.

Health History

Understanding a patient's background enables nurses to connect seemingly disparate facts into a meaningful picture of present and potential issues. Essential historical points include family history, allergies, medication usage, and lifestyle choices.

Risk Assessment

Identifying potential risks allows for focused interventions to reduce complications. Various scoring systems exist for different conditions, enabling comparisons between individuals and populations. Common scales include TIMI Score for chest pain, CURB 65 Score and PSI/PORT Score for pneumonia, NIH Stroke Scale for stroke, and Wells Criteria and CHA₂DS₂-VASc Score for atrial fibrillation.

Case Example

Consider Mr. Smith, aged 75, presenting with shortness of breath and cough. Initially, his blood pressure reads 110/75 mmHg; heart rate is 82 bpm, respiratory rate is 21 breaths per minute, and temperature is 99°F. Based on Mr. Smith's history revealing prior myocardial infarction, continuing antihypertensive and antiplatelet medications, and nonproductive cough, further exploration could involve pulmonary function tests and chest X-ray.
