Sensory Alterations

Chapter 39: Sensory Alterations

Introduction

  • Coverage of sensory alterations as experienced by individuals, particularly focusing on common implications for older adults.

Objectives

  • Differentiate the process of reception, perception, and reaction to sensory stimuli:
      - Reception: Stimulation of sensory receptors (light, touch, sound).
      - Perception: Integration and interpretation of these stimuli by the brain.
      - Reaction: The response to only the most significant stimuli.
  • Compare the relationship of sensory function with an individual’s level of wellness: Understanding how sensory function correlates with overall health.
  • Discuss common causes and effects of sensory alterations: Identification of factors that lead to sensory changes and their impacts on life.
  • Discuss common sensory changes that occur with aging: Noting how aging affects sensory perception and function.
  • Identify factors to assess in determining a patient’s sensory status: Parameters for evaluating a patient’s sensory health.
  • Describe behaviors indicating sensory alterations: Recognizing signs that may indicate issues with sensory reception or processing.
  • Develop a plan of care for patients with sensory deficits: Structuring a care plan tailored to individual sensory needs.
  • Describe nursing interventions with rationales that promote effective communication with patients who have sensory alterations: Strategies for communication considering sensory impairments.
  • Describe conditions in the healthcare agency or patient’s home that you adjust to promote meaningful sensory stimulation: Creating environments that maximize sensory input.
  • Discuss ways to maintain a safe environment for patients with sensory alterations: Ensuring safety standards to accommodate sensory deficits.

Scientific Knowledge Base: Normal Sensation

  • Sensory Reception:
      - The initial stage involving stimulation of sensory nerve fibers.
  • Transmission of Impulses:
      - Impulses are sent to higher brain centers for interpretation.
  • Overall Process of Normal Sensation:
      - Reception → Activation of receptors (like light/touch/sound).
      - Perception → Integration and understanding of stimuli’s significance.
      - Reaction → Response is only triggered by critical stimuli.

Types of Sensory Alterations

  • Sensory Deficits:
      - A deficit in the normal function of sensory reception and perception, leading to the inability to receive certain stimuli.
  • Sensory Deprivation:
      - Insufficient quantity or quality of sensory input, which may impair psychological health.
  • Sensory Overload:
      - Receipt of excessive sensory stimuli that can overwhelm the person’s ability to process information.

Nursing Knowledge Base

  • Common Sensory Alterations in Older Adults:
      - Atrophy of cerumen glands leading to hearing problems.
      - Presbycusis: Age-related hearing loss.
      - Glare sensitivity.
      - Decreased night vision and reduced accommodation/depth perception.
      - Yellowing of the lens affecting color vision.
      - Increased light requirements for adequate vision.
  • Taste and Smell Changes:
      - A decrease in taste sensations.
      - Reduction in sensitivity to smells.
  • Proprioceptive Changes:
      - Alterations in the perception of body position, leading to issues with balance.
  • Tactile Changes:
      - Changes in one's ability to perceive touch, leading to potential injuries.
  • Macular Degeneration:
      - A common vision impairment associated with aging.
  • Emotional and Psychological Effects:
      - Loss of sensory input can result in grief, anger, depression, and diminished self-esteem, potentially leading to social isolation.
  • Importance of Patient Education:
      - Equipping older adults with tools to cope with sensory alterations.
  • Routine Screenings:
      - Effective for early identification of sensory changes in children, notably changes in vision.

Critical Thinking

  • Synthesis of Knowledge:
      - Requires knowledge integrating pathophysiology, communication, and pharmacology.
  • Experience and Attitudes:
      - Utilize informed personal and clinical experiences, along with creative problem-solving.
  • Standards:
      - Maintain ethical and professional standards in patient care.

Nursing Process: Assessment

  • Components of Sensory Status Assessment:
      - Consider physical examination results.
      - Assess lifestyle factors including socialization and self-care management.
      - Evaluate psychosocial adjustment and health promotion practices.
      - Identify potential hazards and degree of meaningful stimuli in the environment.
      - Assess communication methods employed by the patient and their expectations regarding sensory experiences.

Nursing Process: Diagnosis

  • Common nursing diagnoses related to sensory alterations include:
      - Anxiety
      - Fear
      - Impaired Physical Mobility
      - Risk for Injury
      - Deficient Knowledge
      - Impaired Social Interaction
      - Bathing Self-Care Deficit
      - Risk for Falls

Nursing Process: Planning

  • Goals and Outcomes:
      - Collaboration with the patient to set realistic and measurable outcomes.
  • Setting Priorities:
      - Rank nursing diagnoses based on safety, personal desires, and patient needs.
  • Collaborative Care:
      - Involves the patient, family, and other health professionals, including community resources.

Nursing Process: Implementation

  • Adjusting to Sensory Impairments:
      - Patients can learn adaptations at any age with appropriate support.
  • Health Promotion Strategies:
      - Conduct screening and prevention measures.
      - Manage environmental hazards effectively.
      - Encourage the use of assistive aids.
      - Promote meaningful stimuli to enhance sensory experience.
      - Establish safe environments tailored to sensory needs.
      - Implement visual and hearing adaptations, and modifications for smell and tactile experiences.
  • Communication Strategies:
      - Tailor methods of communication to the sensory capabilities of the patient.

Acute Care

  • Measures to Assist Patients in Acute Care Settings:
      - Orientation to their immediate environment.
      - Implementation of safety measures.
      - Effective communication strategies.
      - Control sensory stimuli to avoid overload or deprivation.

Restorative and Continuing Care

  • Goals in Restorative Care:
      - Encourage self-care practices to boost self-esteem.
      - Enhance safety awareness among patients.
      - Promote opportunities for socialization.

Evaluation

  • Evaluating Patient Outcomes:
      - The nature and extent of sensory alterations influence evaluation procedures.
      - When outcomes do not meet expectations, it may be necessary to modify interventions or adjust the patient’s environment.
      - Engage with patients to confirm if their expectations have been met.
