Sensory Changes and Deprivation

Proper Proprioception and Altered Levels of Consciousness

  • Proprioception Definitions and Inquiries

    • The concept of proprioception is introduced as a foundational element of sensory function.

    • The transcript questions the "proper" definition and application of proprioception.

  • Stupor

    • Definition: Stupor is characterized by a patient responding only to repeated extreme pain.

    • Clinical Identification: To determine if a patient is in a state of stupor, clinical assessment focuses on their response to painful stimuli.

    • Diagnosis: A state of stupor is formally diagnosed by a physician or doctor.

    • Recovery Phase: Questions often arise whether the state is identified only once the patient is "out of it" or if it is an ongoing identifiable condition.

Sensory Alterations: Deficits and Deprivation

  • Sensory Deficit

    • A sensory deficit is defined as the absent function in one of more senses.

    • This represents a complete or near-complete loss of specific sensory modalities.

  • Sensory Deprivation

    • Sensory deprivation occurs when there is decreased sensory input reaching the brain.

    • It is often associated with perceptual deprivation.

    • When a patient experiences decreased sensory input, they may suffer from various cognitive or perceptual disturbances.

Sensory Overload

  • Definition and Pathophysiology

    • Sensory overload occurs when the patient is subjected to more stimuli than the brain can process.

    • The brain becomes unable to respond meaningfully to the stimuli.

    • The brain is unable to ignore or filter out stimuli during an overload event.

  • Patient Experience and Manifestations

    • Patients experiencing sensory overload often report feeling completely out of control.

    • The experience involves specific sensory distortions regarding:

      • What things "feel like."

      • What things "sound like."

      • What things "look like."

  • Nursing Interventions for Sensory Overload

    • Acknowledgment: The nurse must acknowledge and discuss the sensory distortions with the patient.

    • Validation: It is critical to reassure the patient that their experience is a normal response to the overload.

    • Prognosis Management: Reassure the patient that these sensations and distortions are usually temporary.

Nursing Strategies for the Older Adult

  • Aging and Sensory Changes

    • Factors affecting sensory changes are especially prevalent in older adults.

    • Nursing strategies must prioritize the unique needs of the elderly population regarding sensory health.

  • Clinical Resources

    • Specific nursing strategies for the older adult are detailed in Chart on page 1,8381,838.

    • This chart provides guidance on managing patients who have sensory overload.

  • Environmental Stimuli and Comfort

    • Nurses should employ visual and environmental stimulation to help orient or comfort the patient, including:

      • The use of comforting colors.

      • The placement of pictures in the environment.

      • Providing opportunities for the patient to look out (e.g., through a window).
