Study Notes
Mild Heat Intolerance & Simple Goiter
- Simple goiter involves thyroid enlargement due to low iodine levels leading to ineffective iodine utilization.
- Patients typically do not exhibit overt thyroid dysfunction.
Assessment & Diagnostic Evaluation
- Evaluation includes taking medical history, physical examination, thyroid scans, and laboratory tests to assess thyroid function.
Medical and Surgical Management
- Medical management includes medications to shrink the thyroid and iodine supplementation.
- Surgical options may involve thyroidectomy for severe cases.
Nursing Implications
- Address potential for distorted body image and provide emotional support.
- Encourage patient expression of feelings regarding dietary and medication adherence.
- Emphasize the need for strict medical supervision and adherence to medications.
Prognosis
- Life expectancy remains normal but can progress to hypothyroidism if untreated.
Thyroid Cancer
- Types include papillary, follicular, and anaplastic carcinoma.
- Diagnosis requires imaging (thyroid scan, ultrasound, CT) and needle biopsy.
Medical and Surgical Management in Thyroid Cancer
- Medical treatment includes radiation, chemotherapy, and radioactive iodine.
- Surgical management may involve total thyroidectomy and radical neck dissection.
Nursing Considerations
- Monitor for signs of low calcium levels and potential thyroid dysfunction (hyperthyroidism/hypothyroidism).
- Watch for infection signs, maintain fluid balance, and ensure follow-up care for hormone replacement.
Prognosis for Thyroid Cancer
- Prognosis varies; papillary carcinoma typically has an excellent prognosis, while follicular and anaplastic types have poorer outcomes.
Adrenal Glands Overview
- Located atop kidneys; consist of adrenal cortex (produces mineralocorticoids, glucocorticoids, and sex hormones) and adrenal medulla (produces epinephrine and norepinephrine).
Cushing's Syndrome
- Characterized by excess corticosteroids due to various causes (hyperplasia, ACTH secretion, corticosteroid use).
- Clinical signs include weight gain, hypertension, and altered glucose metabolism.
Management and Prognosis in Cushing's Syndrome
- Management includes identifying and managing the root cause, and potential surgical tumor removal.
- Prognosis is variable; depend on etiology and success of treatment, often leading to decreased life expectancy due to complications.
Addison's Disease
- Results from adrenal insufficiency and lack of glucocorticoids and mineralocorticoids, commonly caused by autoimmune disorders.
Clinical Manifestations and Management of Addison's Disease
- Common symptoms include fatigue, low blood pressure, and potential for Addisonian crisis.
- Treatment includes lifelong hormone replacement and monitoring for signs of infection.
Addison's Crisis
- Life-threatening condition triggered by stress, surgery, or sudden withdrawal from corticosteroids.
Pheochromocytoma
- Rare adrenal tumor causing excessive catecholamine secretion.
- Management includes monitoring blood pressure and surgical tumor removal for good prognosis.
Case Study on Hypothyroidism
- Presents symptoms of fatigue, weight gain, and puffy face; vital signs indicate bradycardia and possible hypothyroidism.
- Teaching needs include medication adherence and awareness of signs needing immediate medical attention.
Summary of Main Points
- Understand the functional anatomy of thyroid/parathyroid glands and conditions like hyperthyroidism and hypothyroidism.
- Recognize symptoms and management for conditions like simple goiter, thyroid cancer, Cushing's syndrome, and Addison's disease.
HYPERPARATHYROIDISM
- Characterized by overproduction of parathyroid hormone (PTH).
- Clinical manifestations include hypercalcemia, muscle weakness, and bone pain.
DIAGNOSTIC EVALUATION
- Radiographic Examination: Assesses bone integrity.
- Bone Density Measurements: Determines bone mineral density.
- Sestamibi Parathyroid Scan: Identifies abnormal parathyroid tissue.
- MRI/CT/US: Visualizes parathyroid glands.
- Laboratory Tests: Measure calcium and PTH levels.
MEDICAL / SURGICAL MANAGEMENT
- Medical: Close monitoring of calcium levels, administer parathyroid hormones as needed.
- Surgical: Removal of abnormal parathyroid tissue to regulate hormone levels.
NURSING IMPLICATIONS
- Monitor calcium levels and input/output (I&O).
- Administer diuretics and strain urine for kidney stones.
- Educate patients to decrease dietary calcium and monitor for falls.
- Promote good body mechanics to prevent fractures.
PROGNOSIS
- With treatment, average life expectancy is good; parathyroid carcinoma is a grave condition.
HYPOPARATHYROIDISM
- Typified by decreased production of parathyroid hormone (PTH), often idiopathic in nature.
- Common clinical manifestations include hypocalcemia and hyperphosphatemia.
DIAGNOSTIC EVALUATION
- Decreased PTH Levels: Indicative of disorder severity.
- Laboratory Tests: Rule out vitamin D deficiency and kidney failure.
- Glucose Tolerance Test: Monitors blood glucose response.
MEDICAL / SURGICAL MANAGEMENT
- Medical: IV calcium gluconate or calcium chloride to manage acute symptoms, along with vitamin D.
- Surgical: Generally none; focus on medication management.
NURSING IMPLICATIONS
- Careful monitoring of IV sites during calcium administration.
- Educate on dietary restrictions to manage calcium and phosphorus levels.
- Provide instruction to avoid high potassium intake, and ensure stress-free environments.
PROGNOSIS
- Long-term treatment can manage symptoms, leading to normal life expectancy.
ADRENAL GLANDS
- Located atop kidneys, consists of adrenal cortex (releases steroid hormones) and adrenal medulla (produces epinephrine and norepinephrine).
ADRENAL HYPERFUNCTION (CUSHING’S SYNDROME)
- Caused by excess corticosteroid, often due to prolonged corticosteroid use or ACTH-secreting tumors.
- Characterized by obesity, hypertension, and skin changes.
DIAGNOSTIC EVALUATION
- Assess plasma cortisol and ACTH levels alongside clinical appearance.
- 24-hour urine test for cortisol quantification.
MEDICAL / SURGICAL MANAGEMENT
- Address root causes and gradually taper corticosteroid therapy; consider tumor removal, if applicable.
NURSING IMPLICATIONS
- Monitor for infections and manage activity levels to prevent complications.
- Instruct patients to wear medical alert tags due to risk of adrenal crisis.
ADRENAL HYPOFUNCTION (ADDISON’S DISEASE)
- Results from insufficient adrenal hormones; often autoimmune in nature.
- Clinical manifestations include fatigue, nausea, and weight loss.
DIAGNOSTIC EVALUATION
- Measure plasma cortisol and ACTH levels alongside glucose tolerance tests.
MEDICAL / SURGICAL MANAGEMENT
- Hydrocortisone and electrolyte management; high sodium and low potassium diet recommendations.
ADDISON’S CRISIS
- Life-threatening adrenal insufficiency triggered by stress or withdrawal from corticosteroids.
- Requires immediate medical attention.
PHEOCHROMOCYTOMA
- Rare adrenal tumor characterized by excessive catecholamine secretion.
- Symptoms include hypertension and palpitations.
PROGNOSIS
- Surgical removal of tumor leads to good outcomes; untreated cases can be fatal.
CASE STUDY
- Evaluates a patient presenting with fatigue, weight gain, and temperature fluctuations, potentially indicative of hypothyroidism.
- Vital signs show hypertension and bradycardia compared to healthy peers.
SUMMARY OF MAIN POINTS
- Emphasizes understanding thyroid and parathyroid functions, disorders like hyper/hypothyroidism, and relevant clinical manifestations.
- Highlights management strategies to optimize outcomes for patients with these endocrine disorders.
