Study Notes
Management of Patients with Endocrine Disorders (Part 1)
- The nervous and endocrine systems work together to control bodily functions.
- Endocrine system disorders affect all organ systems.
- Endocrine glands secrete hormones directly into the bloodstream.
- Exocrine glands secrete their products through ducts (e.g., digestive tract, sweat glands).
- The hypothalamus links the endocrine and nervous systems.
- The hypothalamus regulates hormone production.
- Hormones influence the nervous system; examples include norepinephrine and epinephrine.
- The immune system interacts with the endocrine system, responding to foreign agents and regulated by adrenal cortex hormones.
- Endocrine glands are anatomically separated in the body.
- Hormones regulate the internal environment and affect all aspects of life.
Endocrine Organs
- Pineal gland
- Hypothalamus
- Pituitary gland
- Thyroid gland
- Parathyroid glands
- Thymus
- Adrenal glands
- Pancreas
- Ovary (female)
- Testis (male)
Cardiac Hormones
- Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are synthesized and secreted by cardiac muscle cells in the atria of the heart.
- These cells contain volume receptors.
- Volume receptors respond to increased stretching of the atrial wall due to increased atrial blood volume
Hormone Regulation
- Hormone concentration in the bloodstream is mostly maintained at a constant level.
- When hormone concentration increases, its production is inhibited.
- When hormone concentration decreases, its production increases.
- This mechanism (negative feedback) maintains homeostasis.
Negative Feedback Example (Calcium Regulation)
- Increased calcium causes a decreased secretion of parathyroid hormone (PTH).
- Decreased calcium causes an increased secretion of PTH.
- This feedback loop maintains calcium homeostasis.
Nursing Assessment
- Health History: Fatigue, energy changes, heat/cold tolerance; changes in weight, sexual function, mood/memory/sleep; family history of endocrine disorders.
- Physical Examination. Height/weight, vital signs (especially blood pressure); skin texture, eye changes (e.g., exophthalmos), facial appearance changes, and extremities.
- Palpation: Thyroid gland palpation, noting size, shape, presence of thrills or nodules.
- Inspection: Assess for changes in appearance.
Diagnostic Tests
- Blood tests: Indicate hormone levels (e.g., T3, T4, calcium, glucose).
- Urine tests: Measure hormone excretion in 24 hours.
- Nuclear Scanning: Identifying tumors or nodules or functioning abnormalities.
- Radiographic tests (CT or MRI): locating tumors or hypertrophy.
- Ultrasound: Identifying masses in thyroid or parathyroid.
- Biopsy: Obtain tissue for examination.
Nursing Interventions Before Thyroid Tests
- Take a thorough patient history.
- Discontinue thyroid medications 7–10 days before the test.
- Avoid iodine-containing medications, excessive iodine intake, and iodine-related tests.
- Inform the patient that no radiation precautions are necessary.
Causes of Endocrine Problems
- Insufficient Hormone Activity: Gland hypo function, lack of tropic or stimulating hormone, target tissue insensitivity to hormone.
- Excess Hormone Activity: Gland hyper function, excess tropic hormone production, excessive replacement medication.
Thyroid Gland Disorder
- Thyroid hormone affects metabolic activity throughout the body.
- See how thyroid hormones are secreted
Hypothyroidism/Hyperthyroidism
- Definitions and characteristics of both conditions
- Etiology
- Signs and symptoms (cardiovascular, neurologic, pulmonary, integumentary, gastrointestinal, reproductive).
- Diagnostic tests
- Therapeutic measures
- Nursing diagnoses Specific to hypothyroidism and hyperthyroidism
Common Goiters
- Endemic (nutritional Iodine deficiency).
- Sporadic (ingestion of goitrogenic foods or goitrogenic drugs).
Thyroid Storm/Thyrotoxic Crisis
- Management objectives, especially considering body temperature and heart rate reduction.
- Specific interventions to treat the crisis
Myxedema
- Characteristics/features of Myxedema, important complications
Thyroid Surgery (Thyroidectomy)
- Methods (traditional vs. minimally invasive)
- Types (total vs. subtotal).
- Circumstances that dictate surgical treatment.
- Preoperative care, including euthyroid status and iodine use.
- Postoperative care including monitoring vital signs, drain care ,prevent hemorrhage.
- Possible complications, including tetany (assessment and interventions)
- Teaching for the patient/caregivers.
Nutritional Therapy for Hyperthyroidism and Hypothyroidism
- High-calorie diet (for hyperthyroidism), 6 full meals + snacks
- Emphasize low-calorie diet or other nutritional strategies (for hyperthyroidism).
Common Nursing Diagnoses for Patient Conditions
- Common nursing diagnoses for patients with hyperthyroidism and hypothyroidism, including those related to nutrition, breathing, activity, knowledge, and body temperature.
Maintaining Normal Body Temperature
- Patients with hyperthyroidism experience increased body temperatures and need a cool environment.
Patient and Caregiver Teaching Guides (for both conditions)
- Importance of thyroid hormone therapy, lifestyle interventions, medication considerations, follow-up care.
Disorders of the Parathyroid Glands
- Overview of parathyroid glands and their role in regulating calcium balance
- Hypoparathyroidism and hyperparathyroidism pathophysiology, symptoms, diagnostic tests, therapeutic measures and nursing interventions
