Assessment Skills

Assessment is the process of turning a patient’s story, appearance, measurements, and examination findings into a clinically meaningful picture. It is more than collecting numbers. The nurse asks what changed, what may explain the change, whether the finding is reliable, and what action the pattern requires. Subjective data come from the patient or caregiver: pain, dizziness, shortness of breath, medication use, and the patient’s description of baseline function. Objective data are observable or measurable: respiratory effort, skin color, blood pressure, pulse, weight, edema, and level of consciousness. A finding becomes more useful when these data agree or when their disagreement is investigated. For example, a patient who says, “I feel fine,” but has new confusion, rapid breathing, and falling oxygen saturation requires assessment beyond the patient’s initial statement. Experienced nurses notice the patient before they begin the formal examination. A change in posture, ability to speak, facial expression, work of breathing, skin color, or interaction may reveal deterioration before a monitor produces an abnormal value. That first impression does not replace measurement; it determines how quickly the measurement and assistance...
