Study Notes
General Safety and Precautions
- Avoid prolonged bending or stooping to prevent strain.
- Exercise caution while using stairs during movements.
- When sneezing, do so with an open mouth to avoid pressure build-up.
Retinal Detachment
- Characterized by separation between sensory retina and retinal pigment epithelium (RPE).
- Symptoms include a sensation of a curtain over one eye, bright flashes of light, and sudden appearance of floaters.
- Diagnostic methods include visual acuity assessment, indirect ophthalmoscopy, slit lamp examination, and fluorescein angiography.
Retinal Detachment - Surgical Treatment
- Scleral buckle is a common procedure that compresses the sclera and is applied around the detachment area or encircles the eyeball.
- Vitrectomy involves removing the vitreous humor to improve access to the retina, followed by injecting gas or silicone for support while requiring face-down positioning post-surgery for optimal healing.
Retinal Surgery - Nursing Management
- Education for patients is crucial, including awareness of complications like increased intraocular pressure (IOP) and infection.
- Patient comfort includes potential need for prone positioning and medication management for discomfort.
Macular Degeneration
- Major cause of blindness in older adults, affecting central vision (54% of cases).
- Drusen deposits in the macula lead to gradual vision blurring.
- Two types: dry (80-90% cases, gradual progression) and wet (more severe, rapid deterioration due to abnormal blood vessel growth).
- Risk factors include family history, smoking, and high cholesterol levels.
Ocular Consequences of Systemic Diseases
- Diabetic retinopathy involves blood vessel damage in the retina, prevalent after prolonged diabetes, often leading to vision loss and blindness.
- Hypertension shows late-stage ocular signs including arterial constriction and retinal hemorrhages.
- Advanced HIV/AIDS can cause cytomegalovirus retinitis, leading to significant visual impairment.
Trauma Management
- Injury prevention through education and immediate treatment is crucial.
- For chemical injuries, flush with water for 20 minutes and save the chemical container for ER personnel.
- Do not remove foreign objects; protect the eye with a shield.
Safety Measures & Education
- Promote education to prevent eye injuries and complication management post-surgery or trauma.
- Patients advised on the use of eye protection and reporting symptom changes.
Ear Assessment and Hearing
- Ear assessments include inspection and otoscopic examination.
- Hearing evaluations utilize gross auditory tests like whisper, Rinne, and Weber tests.
Hearing Impairment
- Presbycusis is an age-related hearing loss primarily affecting higher frequencies.
- Risk factors include prolonged noise exposure.
- Types of hearing loss: conductive (outer/middle ear issues), sensorineural (cochlea damage), mixed, and functional (emotional causes).
Ménière's Disease
- Caused by an inner ear fluid balance disorder leading to sporadic episodes of vertigo, tinnitus, and hearing loss.
Thyroid Hormones
- Comprised of T3, T4, and calcitonin, crucial for metabolism and cellular functions.
- Iodine is essential for hormone production, and deficiency leads to increased TSH and potential goiter formation.
Parathyroid Glands and Hormones
- Regulate calcium and phosphorus metabolism; hyperparathyroidism leads to bone decalcification.
- Hypoparathyroidism presents as hypocalcemia, causing muscle spasms, tingling, and tetany.
Pituitary Disorders
- Disorders include acromegaly (GH overproduction), diabetes insipidus (ADH deficiency), and SIADH (excess ADH).
Acromegaly
- Characterized by enlarged body parts without height increase, due to pituitary tumors.
- Common symptoms include coarse facial features, enlarged extremities, and metabolic complications.
Diabetes Insipidus
- Results from a deficiency in ADH, causing significant urine output and thirst.
- Symptoms include dehydration and electrolyte imbalances; causes can be central (head trauma) or nephrogenic (kidney issues).
Syndrome of Inappropriate Antidiuretic Hormone (SIADH)
- Excess ADH leads to fluid retention and hyponatremia.
- Symptoms range from weakness and headache to confusion and severe cases of coma or death.
Hypothyroidism
- A condition characterized by low thyroid hormone levels, causing decreased metabolism and several systemic effects.
- Common causes include autoimmunity and previous hyperthyroid treatments.### Monitoring & Safety Precautions
- Severe cases require monitoring to prevent circulatory shock; restore blood circulation, administer IV fluids and steroids, and use vasopressors.
- Susceptible to infections; necessitates antibiotics.
- Monitor labs for hyperkalemia and hypoglycemia.
Cushing's Syndrome/Disease
- Characterized by an increase in adrenal cortex hormones.
- Caused by medications, adrenal cortex hyperplasia, or pituitary tumors, especially in patients with asthma or arthritis history.
- Classic signs include central obesity, moon facies, buffalo hump, and abdominal fat.
- Symptoms: weakness, fatigue, hypertension, hyperglycemia, hirsutism, poor wound healing, and muscle wasting.
- Increased androgen secretion in AFAB individuals leads to excessive facial hair and cessation of menses.
- Treatment options: tapering medications, adrenalectomy, or pituitary tumor removal.
- Care focuses on underlying cause, psychological support, cardiac function, infection risk, and skin integrity.
Diabetes Mellitus (DM)
- A chronic disorder marked by hyperglycemia; Type 1 characterized by insufficient insulin production, Type 2 by insulin resistance.
- Prediabetes indicates higher-than-normal blood sugar levels; about one-third of adults are affected.
- Type 1 (insulin-dependent) predominantly affects juveniles; Type 2 (95% of cases) typically seen in adults.
- Gestational diabetes occurs during pregnancy and can lead to macrosomia for newborns.
- Insulin's role: facilitates glucose transport into cells, prevents hepatic glucose release, stores glucose as glycogen.
- Type 1 affects pancreas beta cells, leading to increased blood glucose and ketoacidosis.
- Type 2 presents with insulin resistance, necessitating higher insulin levels to maintain blood sugar.
- Common signs: polyuria, polydipsia, polyphagia, fatigue, vision changes, slow healing wounds, and recurrent infections.
- Long-term consequences include neuropathy, nephropathy, and retinopathy.
- Treatment encompasses education, medication, diet, and physical activity.
Diabetes Treatment - Education
- Understand diabetes basics, targets for blood glucose, and the effects of insulin and exercise.
- Recognize factors affecting glucose levels such as food intake, stress, and illness.
- Administer insulin and oral medications correctly, meal plan attentively, and monitor blood glucose proactively.
- Learn to manage acute complications like hypoglycemia and hyperglycemia.
Diabetes Treatment - Medications
- Start oral medications at low doses, gradually increasing every two weeks.
- Insulin injections are mainly for Type 1; use U-100 syringes noting type, onset, peak, and duration.
- Insulin pumps provide continuous insulin infusion; complications include pump failure and infection.
Diabetes Treatment - Insulin Types
- Rapid-acting: given 10 minutes before meals.
- Regular/short-acting: administered 30 minutes before meals.
- NPH: utilized for glycemic control throughout the day.
- Long-acting: provides a 24-hour effect, administered subcutaneously only.
- Sliding scale dosing adjusts based on glucose readings.
Diabetes Treatment - Diet & Nutrition
- Adopt the plate method: half vegetables, one-quarter proteins, one-quarter carbs.
- Consult with a dietician to respect cultural dietary preferences.
Diabetes Treatment - Physical Activity
- ADA recommends at least 150 minutes of moderate to vigorous aerobic activity weekly.
- Suggests resistance exercises 2-3 times a week.
- Encourage reducing sedentary behavior and integrate flexibility and balance training.
Anemia - Medical Management
- Aim to correct or control the underlying cause of anemia.
- Use packed RBC transfusions and specific treatment depending on the anemia type.
- Consider dietary therapy and supplementation with iron, folate, or Vitamin B12.
Anemia - Implementation
- Promote balance between physical activity, exercise, and rest.
- Educate patients on medication compliance and monitor vital signs.
- Be observant for potential complications such as heart failure and confusion.
Gerontologic Considerations
- Anemia is prevalent among older patients, impacting physical performance and mobility.
- Observe symptoms like fatigue, dyspnea, and confusion more distinctly in elderly patients.
Sickle Cell Disease
- A severe inherited disorder causing hemolytic anemia, characterized by defective hemoglobin (HbS).
- Sickled RBCs block blood flows, leading to painful occlusions in vessels.
- Bone marrow or stem cell transplants remain the only potential cure, suitable mainly for severe pediatric cases with minimal organ damage.
Sickle Cell Disease - Assessment
- Assess health history, physical exam, and pain severity during sickle cell crises.
- Laboratory tests confirm sickle cell presence and assess symptoms' impact.
- Monitor for blood loss and other complications affecting patient life quality.
