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
