Study Notes
Chapter 39: Nursing Care of Patients With Endocrine Disorders
- This chapter focuses on nursing care for patients with endocrine disorders
- Learning outcomes include identifying disorders related to pituitary, thyroid, parathyroid, and adrenal glands
- Understanding the pathophysiology of endocrine disorders is a key learning objective
- Students will learn about the causes, signs, symptoms, and current therapeutic approaches for each disorder
- Data collection methods for patients with endocrine disorders will be explored
- Developing nursing care plans for these patients is a crucial component
- Students should be able to evaluate the effectiveness of nursing interventions
Endocrine Disorders
- Endocrine disorders are characterized by too much or too little hormone activity, problems with production/secretion, altered tissue sensitivity
- Two types of disorders: primary (originates in the gland itself) and secondary (originates elsewhere)
Antidiuretic Hormone (ADH) Disorders
-
Diabetes Insipidus (DI):
- Characterized by insufficient ADH
- Results in excessive urine output (3-15 liters per day)
- Signs and symptoms include polyuria, polydipsia, nocturia, dilute urine, dehydration, hypovolemic shock, decreased level of consciousness, and even death
- Diagnostic tests: urine specific gravity <1.005, increased plasma osmolality, CT/MRI, water deprivation test
- Therapeutic interventions: hypotonic fluids, hypophysectomy (if tumor), IV or subcutaneous vasopressin, DDAVP (synthetic vasopressin)
- Nursing diagnosis: Deficient Fluid Volume
- Expected outcome: patient's fluid balance maintained as evidenced by urine specific gravity between 1.005 and 1.03, stable daily weight, and normal skin turgor
-
Syndrome of Inappropriate Antidiuretic Hormone (SIADH):
- Characterized by too much ADH
- Results in decreased urine output
- Signs and symptoms include weight gain without edema, dilutional hyponatremia (<135 mEq/L), serum osmolality (<275 mOsm/kg), concentrated urine (>1.03), muscle cramps, weakness, brain swelling, seizures, and death
- Diagnostic tests: serum/urine sodium, serum/urine osmolality, CT/MRI
- Therapeutic interventions: eliminate cause (e.g., surgical removal of tumor), fluid restriction, hypertonic saline IV, furosemide (Lasix), conivaptan (Vaprisol)
- Nursing diagnosis: Excess Fluid Volume
- Expected outcome: maintained fluid balance as evidenced by stable weight, normal intake/output, and normal serum sodium levels
Growth Hormone Imbalance
-
Growth Hormone Deficiency:
- Deficient growth hormone (GH) in childhood, but growth not affected in adulthood
- Causes: pituitary tumors, heredity, psychosocial issues, malnutrition
- Signs and symptoms: growth limitation, slowed sexual development, potential mental retardation, fatigue and weakness (specifically in adults), excess body fat, hypercholesterolemia, decreased muscle and bone mass, sexual dysfunction.
- Diagnostic tests: GH level
- Therapeutic interventions: synthetic GH, surgery if necessary
-
Gigantism and Acromegaly (excess GH):
- Gigantism: excess GH in childhood, leading to excessive height
- Acromegaly: excess GH in adulthood, resulting in bone thickening and organ enlargement
- Pathophysiology: excess growth hormone causing bone growth in thickness and width, organ enlargement
- Causes: pituitary hyperplasia/tumors, hypothalamic dysfunction.
- Signs and symptoms: enlarged hands/feet, facial features, difficulty speaking/swallowing, headaches/vision changes, sleep apnea, diabetes mellitus, arthritis, sexual dysfunction, acral enlargement,
- Diagnostic tests: GH level, GH response to oral glucose, bone x-rays, CT/MRI
- Therapeutic interventions: treat cause, hypophysectomy if tumor, medications to block GH, hormone replacement, possibly long-term medical management
Thyroid Hormone Imbalance
-
Hypothyroidism:
- Deficiency in thyroid hormones (TH)
- Causes: congenital factors, inflammatory issues, iodine deficiency, thyroidectomy, autoimmune (Hashimoto's thyroiditis)
- Signs and symptoms: fatigue, bradycardia, constipation, mental dullness, cold intolerance, hypoventilation, dry skin/hair, weight gain, heart failure, hyperlipidemia, myxedema, myxedema coma
- Diagnostic tests: low T3 and T4, high TSH (primary), low TSH (secondary), cholesterol/triglycerides
- Therapeutic interventions: levothyroxine (Synthroid), monitor vitals, warming blankets, mechanical ventilation (severe), intravenous levothyroxine
- Expected outcomes - patient maintains a stable level of hormone in the system, as evidenced by normal vitals and weight
-
Hyperthyroidism:
- Excess thyroid hormones (TH)
- Causes: autoimmune (Graves' Disease), multinodular goiter, toxic adenoma, thyroiditis, pituitary tumor, Synthroid overdose
- Signs and symptoms: hypermetabolic state, heat intolerance, increased appetite, weight loss, frequent stools, nervousness, tachycardia, palpitations, tremor, heart failure, warm smooth skin, exophthalmos (Graves’ disease), thyrotoxic crisis.
- Signs/symptoms in Elderly: heart failure, atrial fibrillation, fatigue, apathy, depression
- Diagnostic tests: elevated T3 and T4, low TSH (primary), high TSH (secondary), TRH stimulation test, thyroid-stimulating immunoglobulin (TSI), CT/MRI (if tumor suspected)
- Therapeutic interventions: methimazole (Tapazole), beta-blockers, radioactive iodine, thyroidectomy, IV fluids (thyrotoxic crisis), cooling blanket, beta-blocker (for fever), acetaminophen, oxygen
Goiter
- Enlarged thyroid gland
- Causes: low TH, iodine deficiency, viral infection, genetic factors, goitrogens
- Signs and symptoms: enlarged thyroid, hypothyroidism/hyperthyroidism/euthyroidism, dysphagia, difficulty breathing, airway compromise (stridor)
- Diagnostic tests: thyroid scan, TSH, T3, T4
- Therapeutic interventions: treat cause, avoid goitrogens, treat hypothyroidism/hyperthyroidism, thyroidectomy (severe cases)
Cancer of the Thyroid Gland
- Tumor of the thyroid gland
- Usually benign, but can be malignant. More common in women
- Causes: hyperplasia, radiation exposure, genetic
- Signs and symptoms: hard, painless nodule, dysphagia, dyspnea (if obstruction), TH usually normal, possibly lymphadenopathy (swelling of lymph nodes)
- Diagnostic tests: thyroid scan ("cold spot"), biopsy.
- Therapeutic interventions: radioactive iodine, chemotherapy, thyroidectomy (partial or total), possibly further treatment depending on the type of thyroid cancer.
Parathyroid Hormone Disorders
-
Hypoparathyroidism:
- Insufficient parathyroid hormone (PTH)
- Causes: heredity, accidental removal during thyroidectomy, autoimmune destruction
- Signs and symptoms: tetany (neuromuscular irritability, numbness/tingling, muscle spasms, cardiac arrhythmias), Positive Chvostek/Trousseau signs, seizures, fatigue
- Diagnostic tests: low PTH, low serum calcium. Positive Chvostek/Trousseau signs
- Therapeutic interventions: IV calcium gluconate (acute), oral calcium with vitamin D (long-term), patient education on medication management and potential complications

- Therapeutic interventions: glucocorticoids and mineralocorticoids daily, double/triple dose during stress, high-sodium diet, education on medication management and signs for Addisonian crisis.
- Complications: adrenal crisis (severe dehydration, hypotension, hypoglycemia, shock, coma, death), require rapid medical intervention.
