    Study Notes

    Hepatic Encephalopathy

    • Life-threatening condition occurring with profound liver failure.
    • Neuropsychiatric manifestation of hepatic failure linked to portal hypertension.
    • Early signs include mental status changes:
      • Motor disturbances
      • Mood and sleep pattern changes: daytime sleepiness and nighttime restlessness
      • Difficulty awakening
      • Asterixis: involuntary flapping of hands
      • Hyperactive deep tendon reflexes (DTR)
      • Fetor hepaticus: sweet, slightly fecal breath odor
    • Progression leads to coma and seizures.

    ### Medical Management

    • Elimination of precipitating causes
    • Lactulose to reduce serum ammonia levels
    • IV glucose to minimize protein catabolism
    • Protein restriction
    • Reduction of ammonia from GI tract via gastric suction, enemas, and oral antibiotics
    • Discontinuation of sedatives, analgesics, and tranquilizers
    • Monitoring and treatment of complications and infections

    ### Nurse Management

    • Maintaining a safe environment to prevent injury, bleeding, and infection
    • Administering prescribed treatments and monitoring for complications
    • Encouraging deep breathing and position changes to prevent respiratory complications
    • Communicating with the patient's family about their status and providing support

    Pituitary Gland

    • Anterior Pituitary: Produces hormones: FSH, LH, Estrogen, Progesterone, PRL, ACTH, TSH, and GH.
      • Hypersecretion: Leads to Cushing's syndrome, gigantism, and acromegaly.
      • Hyposecretion: Leads to dwarfism and panhypopituitarism.
    • Posterior Pituitary: Stores and releases ADH/Vasopressin and oxytocin.
      • Hypersecretion: Causes SIADH Syndrome of Inappropriate Antidiuretic hormone.
      • Hyposecretion: Causes Diabetes Insipidus.

    Parathyroid Glands

    • Located in the posterior part of the thyroid gland.
    • Regulate calcium and phosphorus balance.
    • Hyperparathyroidism: Increased parathyroid hormone leads to enhanced calcium absorption in kidneys, intestines, and bones. Calcium and phosphate levels have an inverse relationship.

    Hypothyroidism

    • Deficiency of T3 and T4 hormones.
    • Caused by thyroid or pituitary gland dysfunction.
    • Common causes include autoimmune diseases like Hashimoto's disease.
    • Symptoms include cognitive delays, small stature, thickened skin, altered facial features.
    • Complications include Myxedema coma.

    Clinical Manifestations of Hypothyroidism

    • Decreased metabolism
    • Fatigue
    • Slowed cognitive function
    • Lethargy

    • Cold intolerance
    • Dry skin
    • Deepened voice

    Nurse Interventions for Hypothyroidism

    • Close monitoring due to prolonged analgesic, sedative, and anesthetic agents

    • Maintenance of airway through suction and ventilator support if necessary

    Hypothyroidism Treatment

    • Synthetic levothyroxine (Synthroid) for life.
    • Monitoring vital signs due to medication-induced increased vitals.

    Hyperthyroidism

    • Excess production of T3 and T4 (thyrotoxicosis).
    • Causes include Graves' disease, toxic adenoma, and thyroiditis.
    • Affects women more than men.

    Clinical Manifestations of Hyperthyroidism

    • Increased metabolic rate and oxygen consumption
    • Tachycardia
    • Palpitations
    • Anxiety
    • Fine hair
    • Muscle wasting
    • Insomnia
    • Increased appetite
    • Weight loss
    • Dysrhythmias
    • Pretibial myxedema
    • Heat intolerance

    Thyroid Storm/Thyrotoxic Crisis

    • Hyperpyrexia (high fever), extreme tachycardia, exaggerated symptoms affecting various systems, altered neurologic/mental state (delirium, psychosis, or coma).

    Nursing Interventions for Hyperthyroidism

    • Monitoring for cardiac issues, heart failure, etc.
    • Placing the patient on a cardiac monitor, monitoring electrolytes, and assessing I&O
    • Administering beta blockers
    • Giving Acetaminophen to reduce fever
    • Providing a cooling blanket and cool environment
    • Improving nutritional status
    • Enhancing coping measures
    • Improving self-esteem
    • Patient education

    Hyperthyroidism Treatment

    • Radioactive iodine therapy: Reduces thyroid tissue or inactivates it.
    • Medications: Propylthiouracil, methimazole, sodium/potassium iodine solutions, dexamethasone, beta-blockers.
    • Methimazole blocks thyroid hormone synthesis.

    Subtotal Thyroidectomy

    • Surgical procedure for hyperthyroidism.

    Hypoparathyroidism

    • Caused by abnormal parathyroid development, vitamin D deficiency, surgical removal, or autoimmune response.
    • Results in inadequate parathormone secretion.
    • Deficiency leads to hyperphosphatemia and hypocalcemia.

    Clinical Manifestations of Hypoparathyroidism

    • Chief symptom: Tetany (involuntary muscle contractions due to low blood calcium)
    • Symptoms/signs: Numbness, tingling, cramps, stiffness, bronchospasms, laryngospasms, carpopedal spasms, dysphagia, photophobia, cardiac arrhythmias, seizures, depression, anxiety, ECG changes.

    Hyperparathyroidism

    • Caused by parathyroid gland overactivity.
    • Affects calcium regulation and is more common in women.
    • Symptoms may be absent in severe cases.
