Study Notes
Eye and Ear Structures
- Significant structures include the eyeball, eyelids, sclera, and pupils, each playing crucial roles in vision.
- Eye functions encompass light reception, focus adjustment, and vision clarity.
- Key components of the ear involved in hearing include the outer ear, middle ear, and cochlea.
Vision Assessment Techniques
-
Visual Acuity Testing
- Utilizes the Snellen chart for measuring vision clarity; 20/20 indicates normal vision at 20 feet.
- Finger count and hand motion tests are alternative methods for assessing visual ability.
-
Eye Examination Procedures
- Slit-lamp examination provides detailed views of anterior eye segments.
- Color vision testing assesses the ability to differentiate colors, crucial for daily activities like traffic navigation.
- Ophthalmoscopy examines the optic nerve through the pupil to reveal optic disc conditions.
- Ultrasonography is utilized for detecting orbital tumors and retinal detachment.
- Gonioscopy evaluates the drainage angle of the eye using a special contact lens with mirrors.
- Tonometer measures intraocular pressure, essential for glaucoma screening.
- Visual field tests assess peripheral vision, identifying potential glaucoma-related vision loss.
Ocular and Hearing Disorders Management
- Clinical features of ocular disorders may include redness, irritation, discharge, and abnormal pupil reactions; similar assessments apply to hearing disorders.
- Diagnostic assessments involve a combination of physical examinations and specialized tests.
- Medical options for managing ocular issues may include prescription medications, and in some cases, surgical interventions.
- Nursing management encompasses patient education, symptom monitoring, and logistical support for treatment compliance.
Ophthalmic Medications and Their Effects
- Therapeutic effects of ophthalmic medications may include reducing inflammation, managing pain, and controlling intraocular pressure.
- Knowledge of medication types is essential for effective patient education and treatment adherence.
General Assessment of Diabetes Patients
- Recent fluctuations in weight, increased fatigue, anxiety, and tiredness may indicate diabetes-related issues.
- Oral health problems, such as gingivitis and periodontal disease, are common in diabetes patients.
- Cardiovascular issues like orthostatic hypotension, cold extremities, and weak pedal pulses need to be assessed.
- Gastrointestinal symptoms may include diarrhea, constipation, bloating, increased flatulence, and abnormal hunger or thirst patterns.
- Genitourinary concerns could involve increased urination, nocturia, impotence, and abnormal vaginal discharge.
- Neurologic symptoms often observed are numbness, tingling in extremities, and altered pain or temperature perception.
Nursing Diagnosis and Interventions
- Risk for Activity Intolerance is tied to poor glucose control; monitor blood glucose levels before and after exercise.
- Encourage consistent exercise planning and carbohydrate intake prior to exercise to prevent hypoglycemia.
- Prolonged strenuous exercise may necessitate increased food intake at bedtime to prevent nocturnal hypoglycemia.
- Patients should avoid exercise if blood glucose levels exceed 250 mg/dL and urine ketones are present; contact healthcare provider if elevated.
Risk for Impaired Skin Integrity
- Risk stems from decreased sensation and circulation to the lower extremities.
- Regular assessment of feet and legs for temperature, sensation, and any injuries is crucial.
- Maintain skin integrity by using protective measures such as heel protectors and special mattresses.
- Avoid drying agents on the skin and apply moisturizers to prevent cracking.
Smoking Cessation
- Patients who smoke should be encouraged to quit to improve peripheral blood flow.
- Help establish behavior modification techniques for smoking cessation both in and out of the hospital.
Foot Care Guidelines
- Daily foot washing and gentle drying, especially between toes, is essential for diabetic patients.
- Cut toenails after a bath for softness; always cut straight across and gently round corners.
- Always wear shoes or slippers to protect feet; ensure proper fit and check for foreign objects inside footwear.
- Avoid barefoot walking, tight/worn footwear, open-toe sandals, and slip-on shoes.
Foot Care Precautions
- Do not attempt to cut nails without clear visibility; avoid cutting the sides of nails.
- Never apply feet directly onto hot water sources to prevent burns.
Monitoring Foot Health
- Monitor for changes in color or temperature, signs of infection, unusual dampness in socks, and any abnormal sensations in the feet.
Risk for Deficient Knowledge
- Assess healthcare literacy to tailor education on oral hypoglycemic agents and exercise for glycemic control.
- Educate on checking medication expiry dates and the importance of adhering to dietary guidelines provided by nutritionists.
Overview of Endocrine System
- The hypothalamus regulates the release of hormones from the pituitary gland, known as the master gland.
- The anterior pituitary secretes several key hormones including Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), Thyroid Stimulating Hormone (TSH), Adrenocorticotropic Hormone (ACTH), Growth Hormone (GH), and Prolactin.
- The posterior pituitary, made of nerve tissue, stores and releases Antidiuretic Hormone (ADH) for urine production regulation and Oxytocin, which induces contractions in reproductive organs.
Pancreas Functionality
- The pancreas plays a critical role in regulating carbohydrate metabolism.
- The endocrine component consists of the Islets of Langerhans: Alpha cells produce Glucagon, Beta cells produce Insulin, Delta cells regulate Alpha and Beta cell function, and F cells inhibit exocrine function.
Anterior Pituitary Gland Conditions
- Disorders may arise from excessive or insufficient secretion of trophic hormones.
- Hypersecretion of Growth Hormone (GH) before puberty leads to conditions such as Giantism.
Wound Management
- Includes tunneling in significant cases.
- Medication options consist of analgesia, antibiotics, and medicated dressings.
- Surgical interventions may involve debridement and skin grafting.
Nursing Responsibilities
- Focus on prevention and assessing clients at risk for pressure ulcers.
- Reposition patients every 2-3 hours to alleviate pressure.
- Utilize protective devices like egg crate mattresses and heel pads.
Ulcer Management
- Employ aseptic techniques in wound care.
- Administer necessary medications as prescribed.
Possible Nursing Diagnoses
- Acute Pain
- Altered Comfort
- Impaired Skin/Tissue Integrity
- Risk for Infection
- Ineffective Coping
Burn Classifications
- Burns are classified by depth and extent, affecting different layers of tissue.
- Superficial burns affect only the epidermis; exhibit pink, dry skin with possible edema.
- Partial-thickness burns involve the epidermis and dermis, forming fluid-filled blisters.
- Full-thickness burns extend to underlying tissues, potentially exposing fat and muscles.
Signs and Symptoms of Skin Conditions
- Common symptoms include weakness, malaise, fever, chills, rash, redness, swelling, dehydration, and pain.
- Skin may display peeling, pimples, blisters, and color changes like hyper/hypopigmentation.
Management of Skin Conditions
- Fluid and electrolyte replacement may be required.
- Possible pharmacological treatments include analgesics, antihistamines, antipruritics, corticosteroids, and antibiotics.
Skin Disorders
- Abnormal skin cell growth, often seen in sun-exposed areas, can lead to malignant tumors.
- Kaposi Sarcoma types:
- Classic KS affects men of Jewish or Mediterranean ancestry.
- Endemic KS primarily affects individuals in eastern Africa.
- Immunosuppression-associated KS occurs in transplant recipients or AIDS patients.
Medical Management for Skin Cancer
- Treatment varies based on type and stage, including surgery, immunotherapy, chemotherapy, and radiation therapy.
Nursing Management for Skin Cancer
- Monitor for changes in moles, new pigmented lesions, ulceration, abnormal rashes, and nodules.
- Possible nursing diagnoses include anxiety, hopelessness, pain, body image disturbance, and ineffective coping.
Pressure Ulcers
- Develop due to unrelieved pressure on bony prominences, impairing blood flow.
- Areas commonly affected include the head, sacrum, hips, and heels.
Stages of Pressure Ulcers
- Stage 1: Skin intact with nonblanchable redness; may be painful.
- Stage 2: Partial thickness loss of dermis with shallow open ulcers; red or pink wound bed may show intact or open blisters.
- Stage 4: Full thickness tissue loss with possible exposure of bone, tendon, or muscle; presence of slough or eschar may be apparent.
