Study Notes
Thyroid Hormones and Calcium
- Calcitonin and PTH work together to regulate blood calcium levels
- Calcitonin promotes calcium storage in bones, PTH stimulates reabsorption in the kidneys
Thyroid Disorders
- Thyroid disorders occur when the thyroid gland produces excess or insufficient thyroid hormones
- Hyperthyroidism: Overactive thyroid, too much thyroid hormone
- Graves' disease (autoimmune disease)
- Overactive thyroid nodules (lumps in the thyroid, usually not cancerous)
- Thyroiditis (inflammation of the thyroid gland)
- Hypothyroidism: Underactive thyroid, not enough thyroid hormone
- Hashimoto's disease (autoimmune disease)
- Thyroiditis (inflammation of the thyroid)
- Surgical removal of part or all of the thyroid
- Pituitary gland tumor
- Radiation treatment of the thyroid
- Thyroid tumor
Signs and Symptoms
- Hyperthyroidism
- Increased heart rate
- Weight loss
- Nervousness
- Tremors
- Heat intolerance
- Enlarged thyroid gland
- Bulging eyes
- Hypothyroidism
- Fatigue
- Weight gain
- Cold intolerance
- Constipation
- Dry skin
- Hair loss
- Slowed heart rate
Hyperthyroidism Complications
- Thyroid storm (thyrotoxic crisis) - rare, potentially life-threatening, caused by untreated hyperthyroidism
- Management of Thyroid Storm:
- Block thyroid hormone synthesis (antithyroid drugs)
- Block thyroid hormone release (iodine)
- Block T4 conversion to T3 (propranolol, propylthiouracil [PTU])
- Block enterohepatic circulation (cholestyramine)
Hypothyroidism Complications
- Myxedema - medical emergency requiring immediate treatment
- Management of Myxedema:
- Thyroid hormone injections
- Glucocorticoid therapy
- Fluid replacement
Diagnostic Procedures
- Physical examination:
- Examine thyroid for enlargement or nodules
- Assess for signs of hyperthyroidism: fast heart rate, tremors, warm and moist skin
- Assess for signs of thyroid eye disease: eye redness, swelling, or bulging of the eyes
- Thyroid tests (T3, T4, and TSH):
- T3 (total): 70-204 ng/dl
- T4 (total): 5-11 ng/dl
- TSH: 0.4 -4.2 mIU/L
- Thyroid antibodies: help diagnose autoimmune thyroid disorders
- Ultrasound: Evaluate thyroid gland size and structure
- Thyroid scan: Uses radioactive iodine, assesses thyroid function and iodine uptake
Hyperthyroidism Management
- Medical Treatment:
- Anti-thyroid drugs: block thyroid hormone production
- Beta-blockers: help control symptoms like heart rate
- Radioactive Iodine Therapy (RAI): destroys thyroid tissue
- Surgical Treatment: Total or partial thyroidectomy
- Nursing Management:
- Preoperative: Assess, prepare for surgery, ensure informed consent
- Postoperative:
- Assessment: Vital signs, pain, incision, complications (laryngeal edema, hemorrhage, respiratory obstruction)
- Common Nursing Diagnoses: Ineffective airway clearance, insomnia, anxiety, disturbed body image
- Nursing Interventions: Monitor airway, manage pain, prevent injury, promote effective communication
- Health Teaching: Postoperative care instructions, wound care, activity restrictions, dietary modifications
Hypothyroidism Management
- Medical Treatment: Thyroid hormone replacement therapy (levothyroxine)
- Nursing Management:
- Assessment: Assess symptoms, monitor vital signs, assess for potential complications
- Common Nursing Diagnoses: Discomfort, abdominal pain, insomnia, disturbed body image, anxiety, low self-esteem, activity intolerance
- Nursing Interventions: Manage respiratory symptoms, control body temperature, promote rest, encourage weight reduction, ensure medication adherence
- Health Teaching: Emphasize medication compliance, follow-up appointments
General Nursing Considerations
- Prioritize nursing diagnoses based on ABC (Airway, Breathing, Circulation)
- Address patient’s psychosocial needs throughout care
- Encourage patient participation in their care plan
- Provide education and emotional support to patients and families
- Follow-up appointments are crucial for ongoing monitoring and management of thyroid disorders
