SLEEP
Patient Turning Frequency
Importance of regularly turning patients to prevent pressure ulcers and improve comfort.
Prevents prolonged pressure on bony prominences, reducing the risk of skin breakdown and tissue ischemia.
Improves circulation and reduces the incidence of deep vein thrombosis (DVT).
Enhances respiratory function by promoting lung expansion and secretion drainage.
Frequency recommendations can vary based on patient condition and type of care setting. Typically every 2 hours, but high-risk patients may require more frequent turning.
Types of Wound Drains
Open Drainage: Drains that allow fluids to flow out freely and may help to reduce pressure and fluid accumulation in a wound.
Example: Penrose drain, which is a soft, flat rubber tube that drains fluid onto a dressing.
Less controlled drainage; requires frequent dressing changes.
Closed Drainage: Uses a suction mechanism to remove fluids, reducing the risk of infection and promoting healing.
Examples: Jackson-Pratt (JP) drain, Hemovac drain.
System is sealed, collecting fluid in a reservoir, allowing for accurate measurement of output.
Reduces the risk of ascending infection compared to open drains.
Wound Vac: A specific type of negative pressure therapy (NPWT).
Purpose: Helps to draw out fluid, decrease edema, promote granulation tissue formation, and speed up wound closure.
Involves applying a vacuum to a wound through a special sealed dressing.
Benefits: Enhances the healing process, decreases the time wounds are open, and reduces frequency of dressing changes. Optimal for chronic or complex wounds.
Sleep
Stages of Sleep: Different stages include NREM (Non-Rapid Eye Movement) and REM (Rapid Eye Movement) sleep.
NREM is further divided into stages 1, 2, 3, and 4, with stage 3 and 4 being deep sleep.
NREM Stage 1 (N1): Lightest stage, transition from wakefulness to sleep. Characterized by slow eye movements.
NREM Stage 2 (N2): Deeper sleep; heart rate and body temperature decrease. Sleep spindles and K-complexes appear on EEG.
NREM Stage 3 and 4 (N3): Deepest, most restorative sleep. Growth hormone is released, and tissues repair—essential for physical recovery and immune function.
REM sleep is associated with dreaming and is important for cognitive function, memory consolidation, and mood regulation. Muscle paralysis typically occurs during this stage.
Sleep Patterns Based on Age Group: Sleep needs and patterns change throughout life.
Infants require more sleep (14-17 hours/day) for growth and development.
Toddlers (11-14 hours/day) and preschoolers (10-13 hours/day) still require significant sleep.
School-aged children (9-11 hours/day) and adolescents (8-10 hours/day) need consistent sleep for academic and social functioning.
Adults (7-9 hours/day) generally fall into a regular pattern.
Older adults (7-8 hours/day) may experience fragmented sleep, waking more often, and spending less time in deep sleep stages.
Common Sleep Disorders: Includes insomnia, sleep apnea, restless legs syndrome, and narcolepsy.
Insomnia: Difficulty falling or staying asleep, leading to daytime fatigue and impaired functioning.
Sleep Apnea: Repeated pauses in breathing during sleep, often associated with loud snoring and daytime sleepiness.
Restless Legs Syndrome (RLS): Irresistible urge to move legs, often accompanied by uncomfortable sensations, worsening at rest or in the evening.
Narcolepsy: Chronic neurological condition characterized by overwhelming daytime sleepiness and sudden attacks of sleep.
Medications Used for Sleep: Various treatments exist, including benzodiazepines, non-benzodiazepines (Z-drugs), and melatonin receptor agonists.
Benzodiazepines (e.g., Temazepam) are CNS depressants that promote sleep but carry risks of dependence and next-day sedation.
Non-benzodiazepines (e.g., Zolpidem) are safer with fewer side effects but still require caution.
Antihistamines (e.g., Diphenhydramine) can cause drowsiness but may have anticholinergic side effects.
Understanding indications, side effects, and contraindications is critical for safe administration.
Patient Teaching for Sleep Medications: Educate about correct use, potential side effects, the importance of not mixing with alcohol or other sedatives, and the risk of rebound insomnia upon abrupt discontinuation. Emphasize short-term use and combining with good sleep hygiene.
Proper Sleep Hygiene: Techniques to improve sleep quality include establishing a regular sleep schedule, creating a restful and dark environment, limiting caffeine and nicotine intake several hours before bed, and avoiding large meals close to bedtime.
Non-Pharmacological Methods to Promote Sleep: Relaxation techniques, such as meditation or deep breathing exercises, can assist in falling asleep. Other methods include a warm bath before bed, listening to calming music, or reading.
Nutrition
Macronutrients:
Carbohydrates: Primary energy source. Example: sugars, starches; contains calories per gram.
Complex carbohydrates (e.g., whole grains) provide sustained energy and fiber.
Simple carbohydrates (e.g., refined sugars) provide quick energy but lack fiber.
Proteins: Essential for body repair and growth, enzyme production, and hormone synthesis. Example: meat, beans; contains calories per gram.
Composed of amino acids, which are building blocks for tissues.
Fats: Important for hormonal balance, energy storage, absorption of fat-soluble vitamins (A, D, E, K), and insulation. Example: oils, nuts; contains calories per gram.
Saturated fats tend to be solid at room temperature and should be consumed in moderation.
Unsaturated fats (monounsaturated, polyunsaturated) are generally healthier and liquid at room temperature.
Complete vs. Incomplete Proteins:
Complete Proteins: Contain all essential amino acids (e.g., animal proteins like meat, poultry, fish, eggs, dairy, and a few plant sources like quinoa and soy).
Incomplete Proteins: Lack one or more essential amino acids (e.g., most plant-based proteins like legumes, grains, nuts, seeds). Can be combined to form a complete protein.
Micronutrients:
Vitamins: Organic compounds that play various roles in bodily functions (e.g., Vitamin C for immune function, collagen synthesis; Vitamin D for calcium absorption and bone health; B vitamins for metabolism).
Minerals: Inorganic elements important for bone health (e.g., calcium, phosphorus), nerve function (e.g., potassium, sodium), and various bodily processes (e.g., iron for oxygen transport, magnesium for muscle function).
Water: Essential for life; aids in digestion, nutrient transport, temperature regulation, lubrication of joints, and waste elimination.
Adults typically need around 2.7 to 3.7 liters (approx. ounces) of total water per day from beverages and food.
Needs increase with exercise, fever, hot weather, and certain medical conditions.
Sources of Vitamins: Fruits, vegetables, grains, and proteins contain different vitamins essential for body function.
Vitamin C: Citrus fruits, berries, bell peppers.
Vitamin A: Carrots, sweet potatoes, dark leafy greens.
Iron: Red meat, beans, spinach.
Calcium: Dairy products, fortified plant milks, leafy greens.
Changes in Nutritional Needs Based on Age Group: Different age groups require different nutrient balances. E.g., children need more calories and protein for growth, while older adults require fewer calories but more vitamins (like D and B12) and calcium due to decreased absorption and bone density concerns.
Pregnant women need increased folic acid and iron.
Athletes require higher calorie and protein intake to support energy demands and muscle repair.
Labs to Assess Nutritional Status:
Key labs include serum albumin, prealbumin, and total protein.
Know Normal Ranges: Importance of understanding normal lab values for clinical assessment.
Albumin:
Prealbumin:
Total Protein:
What Do High or Low Levels Indicate?:
High albumin levels may indicate dehydration, while low levels can indicate malnutrition, liver issues, or inflammation.
Low prealbumin is a more sensitive indicator of acute nutritional changes than albumin due to its shorter half-life and can suggest recent malnutrition.
Low protein levels can also indicate poor dietary intake, malabsorption, or excessive protein loss.
Low Albumin Levels: Suggest potential issues like liver dysfunction, kidney disease (due to protein loss in urine), severe burns, or malnutrition, warranting further investigation. Edema often accompanies very low albumin levels due to reduced oncotic pressure.
NGT (Nasogastric Tube) Considerations
Uses: NGTs are utilized for feeding patients who cannot take in oral food (enteral nutrition), decompression of the stomach, or administering medications.
Decompression: To relieve gastric distension, nausea, and vomiting by suctioning out stomach contents and air (e.g., in cases of bowel obstruction or ileus).
Lavage: Washing out the stomach, e.g., in cases of poisoning or overdose.
Nursing Implications: Nurses must monitor for complications like aspiration, blockage, or dislodgement of the tube.
Regular assessment of the patient's respiratory status is crucial to detect aspiration.
Ensure patency by flushing with water before and after medication administration or feedings.
Provide meticulous oral care to prevent parotitis and maintain comfort.
Monitor input/output (I&O) and weigh the patient regularly for fluid balance assessment.
Monitor skin integrity around the nares.
Confirming Placement: Methods to confirm proper placement of NGT involve methods such as checking pH of aspirate or X-ray.
Gold Standard: Radiographic confirmation (X-ray) is considered the most reliable method for ensuring initial NGT placement, especially before the first use.
pH Testing: Gastric aspirate typically has a pH of less than or equal to . Lung aspirate pH is usually or greater, and intestinal aspirate (from duodenum) is typically or greater.
Visual Inspection of Aspirate: Gastric fluid is often cloudy, green, tan, off-white, or brown. Intestinal fluid is typically yellow or bile-colored. Lung aspirate is usually clear.
Air Instillation/Auscultation: Injecting air into the NGT while listening over the stomach with a stethoscope is
