    Study Notes

    Prevention Interventions

    • Wearing a helmet is a primary prevention intervention to reduce the risk of head injuries during activities.

    Muscle Conditions

    • Hypertrophy refers to the increase in muscle size.
    • Atrophy denotes a decrease in muscle size or wasting away.

    Infection Phases

    • The prodromal phase represents the initial stages of infection, where symptoms begin to emerge.

    Lab Values: Arterial Blood Gases

    • pH: Normal range 7.35-7.45; lower indicates acidity, higher indicates alkalinity.
    • PCO2: Normal range 35-45 mmHg; lower indicates alkalinity, higher indicates acidity.
    • HCO3: Normal range 22-26 mEq/L; lower signifies acidity, higher indicates alkalinity.
    • Acidosis is characterized by excess acid, while alkalosis indicates an excess of base.

    Normal Lab Values

    • Sodium: 3.5-4.5 mEq/L
    • Potassium: 3.5-5 mEq/L
    • Albumin: 3.5-5 g/dL

    Potassium Imbalances

    • Hypokalemia: Serum K+ < 3.5 mEq/L; higher risk in anorexia or hospice patients, can cause constipation.
    • Hyperkalemia: Serum K+ > 5 mEq/L; common in renal failure and burn patients.

    Calcium Imbalances

    • Normal calcium level: 8-10.5 mg/dL.
    • Hypocalcemia: Increased serum pH; symptoms include muscle twitching.
    • Hypercalcemia: Caused by excessive vitamin D or calcium intake; symptoms include muscle weakness, lethargy, and renal issues.

    Respiratory Conditions

    • In patients with COPD, lab values may indicate respiratory acidosis.

    Antacid Use

    • Excessive use of antacids should be reduced; focus on addressing the underlying cause of acid reflux.

    Signs of Dehydration

    • Sunken eyes, low blood pressure, increased pulse rate.

    Fluid Volume Deficit

    • Loss of sodium and potassium leads to dehydration.

    Sodium Imbalances

    • Hypernatremia: Excessive sodium; symptoms include edema and diarrhea.
    • Hyponatremia: Sodium deficit; can result in fatigue, muscle cramps, nausea, seizures.

    Histamine

    • Functions as a chemical mediator in various physiological responses.

    Types of Burns

    • Thermal: Caused by flames or hot fluids.
    • Chemical: Resulting from toxic chemicals.
    • Radiation: Associated with radiation exposure.
    • Electrical, Light, and Friction Burns: Other forms of burns based on their cause.

    Classification of Burns

    • Superficial Partial Thickness (First Degree): Involves only the epidermis, minimal blistering.
    • Deep Partial Thickness (Second Degree): Affects the epidermis and dermis, significant blister formation.
    • Full Thickness (Third and Fourth Degree): Destroys all skin layers and underlying tissues, nerve damage may occur.

    Burn Healing Process

    • Hypermetabolism during healing leads to increased hunger.
    • Immediate wound covering is essential to prevent infection.
    • Healing can be prolonged and may require physiotherapy or surgery for restrictive scar tissue.

    Pediatric Considerations

    • Children with burns experience compromised metabolic needs and may have renal problems due to increased inflammatory mediators.
    • Severe burns can stunt growth as nutrients are redirected for healing.

    Flu Prevention

    • Vaccination and hand hygiene are key to preventing flu.

    Chronic Infection Risk

    • Stopping antibiotics early increases the risk of chronic infections.

    HIV Transmission

    • Transmitted through blood and sexual contact; protected sex is essential.
    • Cannot be contracted through casual contact like hugging.

    Types of Headaches

    • Temporal: Related to temporomandibular joint syndrome.
    • Migraine: Characterized by abnormal brain blood flow, severe throbbing pain.
    • Intracranial: Caused by increased skull pressure due to trauma or tumors.
    • Sinus: Associated with nasal congestion and eye strain.
    • Tension: Resulting from neck muscle spasms, manifests as a dull ache.

    Pain Indicators

    • Verbal: Crying, screaming, or vocalizations can indicate pain.
    • Non-Verbal: Withdrawal from stimuli, grimacing, and guarding behavior signify pain.

    Prevention Interventions

    • Wearing a helmet is a primary prevention intervention to reduce the risk of head injuries during activities.

    Muscle Conditions

    • Hypertrophy refers to the increase in muscle size.
    • Atrophy denotes a decrease in muscle size or wasting away.
