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.
