Study Notes
Thyroid Gland and Disorders
- Hypothyroidism: a condition where the thyroid gland doesn't produce enough thyroid hormones
- Causes: iodine deficiency, thyroiditis, radiation therapy, thyroid surgery
- Risk factors: female, age >50, family history, radiation exposure
- Symptoms: fatigue, weight gain, cold intolerance, dry skin, hair loss
- Hyperthyroidism: a condition where the thyroid gland produces too much thyroid hormones
- Causes: Graves' disease, thyroid nodules, thyroiditis, excessive iodine intake
- Risk factors: female, family history, stress, smoking
- Symptoms: weight loss, anxiety, rapid heartbeat, heat intolerance, tremors
Thyroid Hormone Production
- Dietary substances needed for thyroid hormone production: iodine, selenium, zinc
- Calcitonin: a hormone produced by the thyroid gland that helps regulate calcium levels
- Effects: lowers calcium levels, inhibits bone resorption
Thyroid Function Tests
- Thyroid scan: a diagnostic test that uses radioactive iodine to visualize the thyroid gland
- Purpose: diagnose thyroid disorders, monitor treatment response
- Radioactive iodine uptake test: a test that measures the amount of radioactive iodine taken up by the thyroid gland
- Purpose: diagnose thyroid disorders, monitor treatment response
Thyroid Disorders
- Hashimoto's thyroiditis: an autoimmune disease that causes hypothyroidism
- Causes: autoimmune response, genetic predisposition
- Symptoms: fatigue, weight gain, cold intolerance, dry skin, hair loss
- Graves' disease: an autoimmune disease that causes hyperthyroidism
- Causes: autoimmune response, genetic predisposition
- Symptoms: weight loss, anxiety, rapid heartbeat, heat intolerance, tremors
Complications of Thyroid Disorders
- Hypothyroidism: severe complications include myxedema coma, heart problems, and infertility
- Hyperthyroidism: severe complications include thyroid storm, heart problems, and osteoporosis
Treatment of Hyperthyroidism
- Radioactive iodine: a treatment option for hyperthyroidism that destroys part of the thyroid gland
- Nursing implications: administration of Lugol's solution, patient education on radiation safety
- Safety measures: avoid pregnancy, breastfeeding, and contact with children
Surgical Interventions
- Thyroidectomy: a surgical procedure that removes part or all of the thyroid gland
- Potential complications: hypothyroidism, hypocalcemia, nerve damage
- Nursing interventions: wound care, pain management, calcium supplementation
Parathyroid Gland and Calcium
- Parathyroid gland: a gland that regulates calcium levels
- Relationship with calcium: increases calcium levels, stimulates bone resorption
- Effects of non-functioning parathyroid gland: hypocalcemia, osteoporosis
Hypocalcemia and Hypercalcemia
- Hypocalcemia: a condition characterized by low calcium levels
- Clinical manifestations: muscle weakness, confusion, numbness, tingling
- Treatment: calcium supplementation, Vitamin D
- Hypercalcemia: a condition characterized by high calcium levels
- Clinical manifestations: muscle weakness, kidney stones, bone pain
- Treatment: hydration, medication to lower calcium levels
Chvostek's and Trousseau's Sign
- Chvostek's sign: a clinical manifestation of hypocalcemia characterized by twitching of the facial muscles
- Trousseau's sign: a clinical manifestation of hypocalcemia characterized by muscle cramps and spasms
Test your knowledge on causes, symptoms, and complications of hypothyroidism and hyperthyroidism, as well as the dietary requirements for thyroid hormones. Learn about Hashimoto’s thyroiditis, Grave’s disease, and the purpose of thyroid scans and radioactive iodine uptake tests. Explore nursing implications for pre-procedure care and patient education.
