Which option best represents the three key concepts of health promotion?

A. They allow patients to outline their healthcare wishes if they cannot communicate: Advance directives, such as living wills and durable powers of attorney, ensure that a patient's values guide care when they are incapacitated. These legal documents provide clear instructions for end-of-life decisions and the use of life-sustaining treatments. They protect the patient's right to self-determination even when they can no longer participate in active dialogue.

B. They replace the need for informed consent: Advance directives complement the consent process but do not eliminate the legal requirement for providers to explain procedures to capable patients. If a patient is conscious and competent, they must still provide direct informed consent for any medical intervention. The directive only becomes the primary guide for care when the patient's decision-making capacity is lost.

C. They help nurses determine staffing assignments: The presence or absence of an advance directive does not influence the administrative process of allocating nursing staff to patient care. Staffing is based on patient acuity, nursing competency, and the volume of patients on a unit. While a directive affects the plan of care, it is not used as a metric for organizational workforce management.

D. They are used only during emergencies: While these documents are critical during acute crises, they also guide routine medical decisions for patients with chronic or terminal illnesses. They cover a range of scenarios, from nutritional support to the use of mechanical ventilation in long-term care settings. Their utility extends across the entire healthcare continuum to ensure consistent, goal-concordant care.



A. A patient states their pain is 7/10: Pain is a subjective experience that relies entirely on the individual personal report and internal perception. Although a numerical scale provides a way to quantify the intensity, the data remains subjective because it cannot be independently verified by an outside observer. It reflects the patient's internal state rather than an observable physiological fact.

B. Blood pressure reading of 160/92: This value is a measurable and verifiable physical sign obtained through the use of standardized clinical instrumentation. It provides an empirical observation of the patient cardiovascular status that remains consistent regardless of the observer's opinion. Such data is classified as objective because it is a factual finding discovered during the physical examination process.

C. Patient reports feeling anxious: Anxiety is a psychological state and an internal feeling that the nurse cannot directly measure or see. While the nurse may observe outward signs like tremors, the report of the feeling itself is considered subjective data. The nurse must rely on the patient verbalization to understand the presence and nature of this emotional experience.

D. Patient says they feel dizzy: Dizziness is a symptomatic sensation of lightheadedness or imbalance that is known only to the person experiencing it. Because the clinician cannot feel or objectively measure the sensation of vertigo, it is categorized as subjective information. Objective data would instead include observable signs such as a positive Romberg test or nystagmus during a neurological assessment.
