Study Notes
- Calcitonin, secreted by the thyroid gland, enhances bone formation, inhibits bone breakdown, and lowers blood calcium levels.
- T3 and T4, thyroid hormones, require iodine for synthesis.
- Imbalances in iodine levels can lead to goiter formation, affecting T3 and T4 production.
- Thyroid hormones regulate metabolic rate and are crucial for normal growth and development.
- Medications such as beta-blockers, furosemide (Lasix), and aspirin can interfere with thyroid level testing.
- Following a thyroidectomy, monitor for hypothyroidism and parathyroid dysfunction.
- Hypocalcemia S/S is spasm with obtaining of BP reading is referred to as Trousseau's sign, requiring immediate administration of IV calcium gluconate.
- The parathyroid gland regulates parathyroid hormone (PTH) and calcium levels.
- Changes in calcium, monitor ECG (QT Interval).
- Hyperparathyroidism is often caused by a tumor, leading to increased PTH and elevated calcium levels.
- Hyperparathyroidism can be asymptomatic or cause flank discomfort, potentially indicating kidney failure.
Hypothyroidism
- Primary hypothyroidism results from thyroid gland dysfunction.
- Secondary hypothyroidism can be caused by cancer, brain infection, neurosurgery, or severe head trauma.
- A complication of hypothyroidism is Myxedema coma which presents with generalized edema, altered mental status, and low body temperature.
- Clinical signs of hypothyroidism in females includes heavy menstruation, muscle cramping, fatigue, anxiety, depression, and prolonged QT interval.
- Levothyroxine is used to treat hypothyroidism.
- Call PCP if chest pain occurs when taking Levothyroxine
- When taking Levothyroxine, monitor heart rate and hold if it exceeds 100 bpm.
- Have suction available at bedside when treating patient with Myxedema Coma.
Hyperthyroidism
- Hyperthyroidism involves excessive thyroid hormone secretion.
- Graves' disease is characterized by high levels of TSH autoantibodies; sunlight/light may cause head pain.
- Hashimoto's thyroiditis involves thyroid cell destruction, releasing stored T3 and T4.
- Thyroid storm is a complication of hyperthyroidism characterized by elevated temperature, diarrhea, and high heart rate.
- Priority assessments in Delirium pt with hyperthyroid includes monitoring for increasing temperature, increased peripheral pulses, or lung crackles.
- Cardiac monitoring is essential due to the risk of dysrhythmia in hyperthyroid patient.
- If receiving radioactive iodine ensure you monitor for signs of worsening hyperthyroid with increased temperature (THYROID STORM).
Addison’s Disease
- Addison's disease is caused by adrenocortical insufficiency.
- Primary Addison's disease is an autoimmune condition where the body cannot produce cortisol.
- Secondary Addison's disease can result from corticosteroid therapy.
- Diagnosis involves the Adrenocorticotropic Hormone (ACTH) stimulation test, where the patient fails to produce cortisol.
- Treatment includes hydrocortisone, a steroid that causes immunosuppression.
- Those with Addison's Disease should carry an emergency steroid kit and avoid strenuous activity, particularly in hot weather.
- Diet modifications for Addison's include high salt, high carbohydrate, and high protein intake.
Cushing’s Disease
- Cushing’s disease involves increased cortisol levels.
- Clinical manifestations include hyperglycemia, hypokalemia, and hypertension.
- Diagnosis involves testing ACTH to differentiate between primary and secondary conditions.
- The Dexamethasone Suppression Test involves administering 1mg of dexamethasone orally at night and measuring serum cortisol levels in the morning; a normal result shows decreased cortisol levels.
- Elevated cortisol levels may indicate a tumor or hypersecretion of cortisol.
