    Study Notes

    Thyroid Gland

    • Thyroid hormones increase metabolic rate, and high levels can lead to palpitations, warm and flushed skin, and trouble closing the eyes, which can cause dry eyes, infections, and corneal ulcers.
    • Exophthalmos (bulging eyes) may or may not be reversible with hormone correction, and surgery may be required.
    • Goiter (enlarged thyroid gland) results from abnormal stimulation and hormones.

    Hypothyroidism

    • Characterized by decreased heat production, cold intolerance, and decreased appetite, leading to weight gain due to water retention and slow metabolic rate.
    • Peristalsis (muscle contractions) decreases, and thyroid hormone levels are low.

    Hyperthyroidism

    • Higher metabolic rate results in weight loss, palpitations, warm and flushed skin, and trouble closing the eyes.
    • Exophthalmos may occur, and surgery may be required to correct it.
    • Goiter can develop, and thyroid hormone levels are high.

    Adrenal Gland

    Cortex

    • Hypofunction: Addison's disease (chronic) or Addisonian crisis (acute)
    • Hyperfunction: Cushing syndrome (excess glucocorticoids) or congenital adrenal hyperplasia/adrenogenital syndrome (excess androgens)

    Medulla

    • Hypofunction: no significant effect
    • Hyperfunction: pheochromocytoma (excess catecholamines)

    Thyroid Hormones

    • Thyroid hormones play a crucial role in regulating metabolism, growth, and development
    • Functions of thyroid hormones include:
      • Regulating metabolic rate
      • Controlling growth and development
      • Influencing cardiovascular and nervous system function

    Hyperthyroidism

    • Hyperthyroidism is a condition where the thyroid gland produces excessive amounts of thyroid hormones
    • Pathological change:
      • Overproduction of thyroid hormones (T3 and T4)
      • Enlargement of the thyroid gland
    • Nursing problem:
      • Normalizing hormone levels is the goal
    • Radioactive iodine therapy is the treatment of choice
    • Assessment findings:
      • Increased basal metabolic rate (BMR)
      • Increased heart rate and force of contraction
      • Palpitations
      • Increased respiratory rate
      • Warm and flushed skin
      • Uneven hyperpigmentation

    Hypothyroidism

    • Hypothyroidism is a condition where the thyroid gland produces insufficient amounts of thyroid hormones
    • Pathological change:
      • Underproduction of thyroid hormones (T3 and T4)
    • Nursing problem:
      • Normalizing hormone levels is the goal
    • Antithyroid medications are used to suppress hormone production

    Addisonian Crisis

    • Addisonian crisis is a life-threatening condition characterized by acute adrenal insufficiency
    • Risk groups:
      • People with Addison's disease due to hormone deficiency
      • Steroid-dependent individuals
    • Symptoms:
      • Increased heart rate
      • Increased glucose levels
      • Palpitations
      • Pain in the head
      • Increased blood pressure
      • Increased respirations
    • Treatment:
      • Temporary increase in hormone levels to prevent shock during crisis
