Nursing Concepts: Comfort, Pain, Fatigue, and Sleep

Flashcards covering key terminology and physiological concepts regarding comfort, nociception, pain assessments, fatigue, and health promotion from Chapter 1 through Chapter 7.

Comfort Theory

A nursing theory defining comfort as the immediate state of being strengthened by having needs for relief, ease, and transcendence addressed in physical, psychospiritual, sociocultural, and environmental contexts.

Comfort

A state of physical and emotional well-being that is entirely subjective and defined by what the patient says it is.

Maslow's Hierarchy of Needs

A foundational framework asserting that basic physiologic survival needs, such as breathing, food, and shelter, must be met before higher-level needs can be addressed.

Subjective Assessment Data

Information provided directly by the patient regarding their personal feelings, perceptions, and self-reported comfort levels.

Objective Assessment Data

Measurable and observable clinical cues gathered by healthcare providers, including vital signs and nonverbal physical behaviors.

Fifth Vital Sign

A designation given to pain to highlight the importance of assessing it continuously alongside temperature, pulse, respirations, blood pressure, and oxygen saturation.

Nociception

The physiological process of pain signaling that involves pain receptors detecting stimuli and sending signals to the central nervous system.

Nociceptors

Free nerve endings distributed throughout the body that act as receptors to send pain signals to the central nervous system.

Transduction

The first phase of nociception where a mechanical, chemical, or thermal painful stimulus is converted into an electrical signal.

Transmission

The second phase of nociception where pain signals travel via nerve fibers from the injury site to the spinal cord, often initiating protective motor reflexes.

Perception

The third phase of nociception occurring when the pain signal reaches the cerebral cortex and the individual consciously perceives pain characteristics like location and intensity.

Modulation

The final phase of nociception in which the brain releases endogenous opioids and sends inhibitory signals down the spinal cord to slow pain transmission.

Endogenous Opioids

The body's natural painkilling chemicals released by the central nervous system to reduce pain signal transmission during modulation.

Acute Pain

Pain with a sudden onset that resolves within 3 months or when underlying damage heals, typically causing temporary elevation in blood pressure, heart rate, and respirations.

Chronic Pain

Pain lasting longer than 3 to 6 months past normal healing time, during which the body physiologically adapts, often resulting in normal vital signs despite persistent pain.

Wong-Baker Scale

A pain rating tool featuring drawn faces that depict levels of discomfort, useful for pediatric patients, nonverbal clients, or individuals with cognitive or language barriers.

BOLD SPA

A pain assessment mnemonic representing Character, Onset, Location, Duration, Severity, Pattern, and Associated factors.

Fatigue

A state of physical or mental exhaustion that is distinct from simple tiredness because it does not resolve with rest.

Diphenhydramine

The generic name for Benadryl, an over-the-counter drug that helps initiate sleep onset but degrades circadian rhythms and prevents deep sleep.

Primary Health Promotion

Independent nursing actions aimed at educating patients on lifestyle modifications to prevent discomfort, enhance sleep, and maintain overall wellness.
