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.
