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
- Weight gain without increased calorie intake
- Cold intolerance
- Dry skin
- Deepened voice
Nurse Interventions for Hypothyroidism
- Close monitoring due to prolonged analgesic, sedative, and anesthetic agents
- Assessment of respiratory rate, pulse, and arterial blood gases
- Encouraging deep breathing, coughing, and spirometer use
- Verification of provider orders for hypnotics and sedatives until euthyroid state achieved and monitoring side effects
- 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.
- Symptoms/signs: Fatigue, muscle weakness, nausea/vomiting, constipation, high blood pressure, cardiac dysrhythmias.
Treatment of Hyperparathyroidism
- Surgical: Parathyroidectomy
- Hydration therapy: 2000 mL or more fluid intake daily.
- Maintain mobility
- Avoid thiazide diuretics as they increase calcium retention.
Hypercalcemic Crisis
- Calcium levels exceeding 13 mg/dL affecting neurologic, cardiac, and kidney function.
Treatment/Management of Hypercalcemic Crisis
- Rapid rehydration with isotonic saline IV and calcitonin to promote renal excretion of excess calcium and reduce bone absorption.
- Combinations of calcitonin and corticosteroids in emergencies to lower serum calcium levels.
Nursing Interventions for Hypercalcemic Crisis
- Close airway monitoring.
Adrenal Glands
- Responsible for producing corticosteroids.
Adrenocortical Insufficiency (Addison's Disease)
- Insufficient production of steroids by the adrenal glands, Specifically, too little cortisol.
Clinical Manifestations of Addison's Disease
- Dark pigmentation of skin and mucosa
- Muscle weakness
- Lethargy
- Gastrointestinal symptoms: Anorexia, weight loss, nausea and vomiting
- Low blood pressure
- Low blood glucose
- Low serum sodium
- Confusion
- Emotional lability
- High potassium levels
Addisonian Crisis
- Severe hypotension, cyanosis, fever, nausea and vomiting, and shock.
Nursing Interventions for Addisonian Crisis
- Administering fluids
- Monitoring vital signs and blood glucose
- Performing adrenocortical hormone level tests
- Performing ACTH stimulation tests.
Treatment of Addisonian Crisis
- Fluids administered IV.
- Corticosteroids (patient should lie down with legs elevated).
Cushing's Syndrome
- Excessive cortisol production due to corticosteroid medications or adrenal cortex activity.
Clinical Manifestations of Cushing's Syndrome
- Hyperglycemia
- Central obesity
- Buffalo hump in the neck
- Heavy trunk and thin extremities
- Thin skin
- Easy bruising
- Weakness
- Sleep disturbances
- Osteoporosis
- Muscle wasting
- Hypertension
- Moon face
- Acne
- Slow wound healing
- Loss of libido
- Mood changes
- Increased sodium and blood pressure
- Increased blood glucose
- Decreased potassium
Nursing Interventions for Cushing's Syndrome
- Maintaining adequate cardiac output
- Decreasing risk of injury and infection
- Promoting skin integrity
- Improving body image and coping mechanisms
- Monitoring and managing potential complications (Addisonian crisis)
- Patient education
### Cushing's Syndrome Testing
- Low-dose dexamethasone (corticosteroids) is administered to assess the body's response.
