Study Notes
Anatomy and Physiology
Thyroid Gland
- Responsible for producing hormones that regulate metabolism, growth, and development.
Parathyroid Gland
- Functions primarily to regulate calcium levels in the blood and bone metabolism.
Disorders of the Parathyroid Gland
Hyperparathyroidism
- Condition characterized by excessive secretion of parathyroid hormone (PTH).
Clinical Manifestations and Complications
- May lead to hypercalcemia, kidney stones, osteoporosis, and neuromuscular symptoms.
Diagnostics
- Serum PTH: Increased
- Serum Calcium: Increased
- Serum Phosphate: Decreased (normal range: 2.5-4.5 mg/dL)
- Urine Calcium: Increased
- Bone Density: Decreased
Management
- Focuses on correcting calcium imbalance and addressing underlying causes.
Pharmacology
- Loop Diuretics (Furosemide): Increases urinary excretion of calcium.
- Bisphosphonates (Alendronate - Fosamax): Inhibits bone resorption, normalizes serum calcium, and improves bone density; IV forms can quickly lower high calcium levels. Administration notes include taking with a full glass of water, 30 minutes before meals, and avoiding lying down for 30 minutes.
- Phosphates: Administered for low phosphate levels; renal function monitoring is crucial.
Nursing Management
- Focus on monitoring calcium and phosphate levels and educating patients on dietary modifications.
Hypoparathyroidism
- Characterized by insufficient parathyroid hormone leading to low calcium levels.
Clinical Manifestations
- Symptoms include muscle cramps, tetany, and potential seizures.
Diagnostics
- Serum PTH: Decreased (normal range: 10-65 pg/mL)
- Serum Calcium: Decreased
- Serum Phosphate: Increased (normal range: 2.5-4.5 mg/dL)
Nursing Management
- Emphasis on calcium replacement therapy and education on dietary sources of calcium and vitamin D.
Disorders of the Thyroid Gland
Hyperthyroidism
- Condition of excessive thyroid hormone production; can lead to a thyroid storm, a severe life-threatening condition.
Clinical Manifestations
- Symptoms include weight loss, increased appetite, anxiety, insomnia, and heat intolerance.
Diagnostics
- Typically includes blood tests for thyroid hormones (TSH, T3, T4).
Interventions
- Management may involve antithyroid medications, radioactive iodine, or surgery.
Hypothyroidism
- Characterized by insufficient thyroid hormone production.
Clinical Manifestations
- Symptoms include fatigue, weight gain, cold intolerance, and depression.
Diagnostics
- Blood tests for elevated TSH and low T3 and T4 levels.
Management
- Treatment typically includes levothyroxine replacement therapy for hormone regulation.
Nursing Management
- Monitoring for medication adherence and effectiveness, and educating about dietary adjustments to support thyroid health.
