Psychosocial Care & Communication

Therapeutic Interaction Strategies

24.1 Meaning and Relevance

• Therapeutic interaction is a structured, client-oriented method used to foster a meaningful and supportive connection between nurse and patient.
• It emphasizes identifying the client’s concerns, creating emotional safety, and promoting open communication.

24.2 Essential Elements

• Attentive Listening: Focusing on both spoken words and body language; maintaining appropriate eye contact and posture that conveys presence.
• Emotional Insight: Acknowledging the patient’s emotional state and offering genuine understanding of their situation.
• Exploratory Questions: Using prompts that allow the patient to elaborate (e.g., “Can you describe what’s been going on with you lately?”).
• Clarifying and Confirming: Asking for more details when messages are unclear (e.g., “What do you mean when you say you feel ‘off balance’?”).
• Reflecting Back: Restating what the patient said using your own words to ensure shared understanding.
• Highlighting Key Points: Summarizing conversations to reaffirm what’s been discussed and support decision-making.

24.3 Barriers to Effective Communication

• Unrealistic Promises: Statements like “Everything will be okay” can mislead and shut down patient expression.
• Invalidating Emotions: Comments such as “It’s not so bad” can make patients feel unheard.
• Diverting Focus: Changing topics can block emotional release or support.
• Imposing Solutions: Offering personal opinions can hinder the patient’s ability to make empowered choices.
• Invasive Questioning: Asking too many personal questions without regard to emotional readiness can harm rapport.

24.4 Cross-Cultural Sensitivity

• Be aware of variations in interpersonal distance, eye contact customs, physical contact, and language proficiency.
• Use trained interpreters instead of relying on family members or ad hoc translators.
• Honor diverse traditions or communication norms that may impact how individuals express themselves (e.g., use of silence to show deference).

Physiological Integrity

A. Basic Care and Comfort

Mobility & Immobility (ROM, Positioning, Prevention of DVT)

32.1 Understanding Mobility and Its Significance

• Mobility: The capacity to move independently and easily, which supports muscle strength, joint health, and overall well-being—both physical and mental.
• Immobility: Reduced or absent movement ability, which can cause complications such as muscle wasting, joint stiffness, and poor circulation.

32.2 Consequences of Immobility

• Musculoskeletal: Loss of muscle mass, decreased bone strength increasing osteoporosis risk, and development of joint stiffness or contractures.
• Cardiovascular: Drop in blood pressure upon standing (orthostatic hypotension), reduced blood flow back to the heart, and higher chance of forming blood clots in veins (DVT).
• Respiratory: Reduced lung capacity and ventilation, increasing susceptibility to lung infections like pneumonia.
• Digestive: Slower bowel movements leading to constipation and diminished appetite.
• Mental Health: Feelings of sadness, worry, and negative changes in self-esteem or self-image.

32.3 Range of Motion (ROM) Activities

• Active ROM: Exercises the patient does by themselves to keep muscles strong and joints flexible.
• Passive ROM: Movements performed by the nurse or caregiver on patients who cannot move joints alone, helping to avoid stiffness and contractures.
• Best Practices:
  • Move joints gently and deliberately, providing support above and below the joint.
  • Avoid forcing movement past the joint’s comfortable range, especially if the patient feels pain.
  • Schedule ROM exercises regularly, typically twice daily or as ordered.

32.4 Positioning Techniques

• Goals: Enhance patient comfort, prevent pressure injuries, ensure correct body alignment, and support breathing.
• Common Positions:
  • Fowler’s (High, Semi): Helps those with breathing difficulties by improving lung expansion.
  • Supine: Patient lies flat on their back, often used postoperatively.
  • Prone: Lying face down, used to aid drainage in certain lung conditions and reduce pressure on the back.
  • Lateral (Side-Lying): Assists in preventing pressure sores over bony areas.
  • Sims’: A semi-prone posture often utilized for rectal procedures.
• Important Tips: Turn or reposition patients at least every two hours when confined to bed, and use pillows or special mattresses to provide extra support.

32.5 Preventing Deep Vein Thrombosis (DVT)

• Factors Increasing Risk: Prolonged immobility, recent surgery, excessive body weight, smoking, some medications (like birth control pills), and inherited clotting issues.
• Preventive Actions:
  • Wearing compression stockings to improve blood flow.
  • Using devices that intermittently squeeze the legs to encourage circulation.
  • Encouraging early walking after surgery or illness.
  • Ensuring adequate fluid intake.
  • Administering blood thinners (e.g., low molecular weight heparin) as directed by a healthcare provider.

Summary of Mobility Interventions

Intervention	Purpose	Key Points
Active ROM Exercises	Support muscle tone and joint mobility	Patient actively moves limbs without assistance
Passive ROM Exercises	Avoid joint stiffness and maintain flexibility	Caregiver moves the patient’s joints through full range
Repositioning	Reduce risk of skin breakdown and increase comfort	Change patient’s position every two hours; use cushions or specialized mattresses
Compression Stockings	Promote blood flow in legs	Ensure proper sizing; remove periodically to check skin health
Early Ambulation	Boost circulation and lower risk of clots	Assist patient to sit, stand, and walk briefly as able

  • Nasointestinal (NJ) Tube: Inserted to bypass the stomach, suitable for patients with slow stomach emptying or high risk of aspiration.
  • Gastrostomy Tubes (G-Tube or PEG): Surgically placed feeding tubes for long-term nutritional support directly into the stomach.
• Nursing Responsibilities:
  • Confirm tube placement before feeding (e.g., by checking gastric fluid pH or aspirate).
  • Administer formula at the correct rate, concentration, and temperature.
  • Flush tubes with water before and after feedings or medication administration to prevent clogging.
  • Monitor for possible issues like aspiration, diarrhea, tube dislodgement, or infection at the insertion site.

33.3 Total Parenteral Nutrition (TPN)

• Description: Delivery of essential nutrients directly into the bloodstream for patients whose digestive systems cannot absorb food.
• When Indicated: Conditions like severe malabsorption, extended bowel rest due to diseases such as Crohn’s, short bowel syndrome, or significant trauma/burns with increased nutritional needs.
• Nursing Care Considerations:
  • Requires placement of a central venous catheter (e.g., subclavian line, PICC line).
  • Frequently monitor blood sugar levels due to risk of elevated glucose.
  • Replace TPN solution and tubing every 24 hours under sterile conditions.
  • Watch for signs of infection (fever, redness at the catheter site) and metabolic problems like fluid overload or electrolyte disturbances.

Common Dietary Modifications & Their Uses

Diet Type	Main Purpose	Key Features

  • Report promptly any decrease in urine output, hematuria, sediment presence, or symptoms suggestive of a urinary tract infection.

34.4 Ostomy Care

• Definition: Surgical creation of an artificial opening (stoma) for elimination of feces or urine, such as colostomy, ileostomy, or urostomy.
• Assessment:
  • The stoma should be moist and have a healthy pink to red color; paleness or dark discoloration may indicate poor circulation.
  • Inspect the skin around the stoma for signs of irritation or damage.
• Appliance Management:
  • Select a pouching system that fits securely around the stoma to prevent leaks.
  • Empty the ostomy pouch when it is one-third to half full to reduce risk of leakage.
  • Replace the entire appliance based on facility protocols or immediately if leaks occur.
• Patient Instruction:
  • Teach correct cleaning and measuring techniques for the stoma.
  • Counsel on dietary adjustments, especially for ileostomy patients, to avoid high-fiber foods that may obstruct the stoma.
  • Provide information about support services such as ostomy nurse consultations and patient support groups.

B. Drug Therapy Fundamentals (10%-16%)

Pharmacokinetics & Pharmacodynamics (Drug Processing and Effects)

38.1 Pharmacokinetics

• Definition: The examination of how medications are absorbed, moved through the body, chemically altered, and eliminated.
• Major Steps:
  1. Absorption: Transfer of a medication from its administration site into the bloodstream.
     • Affected by administration method (oral, intravenous, intramuscular, subcutaneous), medication formulation, stomach acidity, and food intake.
  2. Distribution: Movement of the drug via blood circulation to various tissues and organs.
     • Influenced by how much drug binds to plasma proteins (such as albumin), regional blood flow, and cell membrane permeability.
  3. Metabolism (Biotransformation): Chemical changes to the drug, mainly in the liver through enzymes like cytochrome P450.
     • Factors such as liver health, age, and genetic differences impact metabolism.
     • First-pass metabolism refers to the significant breakdown of orally taken drugs by the liver before reaching general circulation.
  4. Excretion: Removal of the medication or its byproducts from the body, primarily via the kidneys.
     • Kidney function, measured by glomerular filtration rate (GFR), is crucial; other excretion routes include bile, feces, sweat, and saliva.

38.2 Pharmacodynamics

• Definition: The study of how drugs affect the body at the molecular and physiological level.
• Core Ideas:
  • Receptor Interaction: Drugs attach to cellular receptors either to activate (agonists) or block (antagonists) specific biological responses.
  • Therapeutic Outcome: The intended beneficial effect produced by the drug.
  • Potency vs. Efficacy: Potency refers to the minimum dose needed to produce an effect; efficacy is the greatest effect achievable by the drug.
  • Therapeutic Window: The range between a drug’s effective dose and its toxic dose; medications with a narrow window (like digoxin, lithium) need careful monitoring.

Administering Medications (The 6 Rights, Routes, and Dosage Calculations)

39.1 The “6 Rights” to Ensure Safe Medication Delivery

• Right Patient: Verify the patient’s identity using two separate identifiers (e.g., full name and date of birth).
• Right Drug: Confirm the medication label matches the medication administration record (MAR) at three points — when retrieving, preparing, and giving the drug.
• Right Dose: Double-check dose calculations and consider individual patient factors such as age, body weight, and kidney function.
• Right Route: Follow the prescribed administration route (oral, IV, IM, subcutaneous, etc.), confirming appropriateness.
• Right Time: Give medications according to the prescribed schedule (e.g., every 8 hours, as needed) and consider timing related to meals.
• Right Documentation: Accurately document the administration immediately, including time, dose, and patient reactions.

39.2 Typical Routes for Medication Delivery

• Enteral: Via mouth or feeding tubes (nasogastric, gastrostomy).
• Parenteral: Injectable routes including intravenous (fastest effect), intramuscular, subcutaneous, and intradermal.
• Topical: Applied to skin, transdermal patches, eyes, ears, or nasal passages.
• Inhalation: Delivered through devices such as nebulizers or inhalers.

39.3 Calculating Dosages

• Basic Formula: (Desired Dose ÷ Available Dose) × Quantity = Amount to administer.
• Weight-Based Dosing: Used frequently in pediatrics and chemotherapy, calculated per kilogram of body weight (mg/kg).
• IV Flow Rates:
  • Manual drips measured in drops per minute (gtt/min).
  • Infusion pumps set in milliliters per hour (mL/hr).
• Double Verification: Medications considered high-risk (e.g., insulin, heparin) generally require confirmation by a second nurse to prevent errors.

Common Abbreviations for Medication Administration

Abbreviation	Meaning	Example/Notes
q12h	Every 12 hours	e.g., 8 AM and 8 PM dosing
qd	Once per day	Avoid using—write “daily” to prevent errors
prn	As necessary	For example, pain relief medications
ac	Before meals	Take medication prior to eating
pc	After meals	Usually administered about 30 minutes post-meal

Medications with High Risk Profiles (Insulin, Heparin, Digoxin, Warfarin)

40.1 Insulin

• Types:
  • Rapid-acting (e.g., lispro), short-acting (regular), intermediate-acting (NPH), and long-acting (glargine).
• Key Nursing Points:
  • Always confirm the dose and type with another nurse before giving.
  • Change injection sites regularly to avoid tissue damage like lipodystrophy.
  • Be alert for signs of low blood sugar such as rapid heartbeat, shaking, sweating, and confusion.
  • Understand each insulin’s timing for onset, peak effect, and duration to coordinate meals properly.

40.2 Heparin (Unfractionated)

• Mechanism: Stops fibrinogen from becoming fibrin, which helps prevent blood clots.
• Routes: Administered via subcutaneous injection or intravenous infusion.
• Monitoring: Use aPTT tests to keep the blood’s clotting time within 1.5 to 2.5 times the normal level.
• Reversal Agent: Protamine sulfate counteracts its effects.
• Low Molecular Weight Heparin (e.g., Enoxaparin): Provides more consistent dosing and requires less frequent lab monitoring but still carries bleeding risks.

40.3 Digoxin

• Function: Boosts the strength of heart contractions and lowers heart rate; commonly prescribed for heart failure and atrial fibrillation.
• Therapeutic Level: Has a narrow safe range, typically between 0.5 and 2.0 ng/mL.
• Toxicity Indicators: Gastrointestinal upset (nausea, vomiting), visual disturbances like seeing halos or yellow tint, and slow heart rate.
• Nursing Actions:
  • Check the apical pulse for a full minute before giving; withhold if below 60 bpm in adults.
  • Monitor potassium levels carefully, as low potassium can increase the chance of toxicity.

40.4 Warfarin

• Mechanism: Blocks vitamin K-dependent clotting factors to reduce blood clotting.
• Monitoring: Regularly check PT/INR levels; the target INR is generally between 2 and 3 for most patients.
• Antidote: Vitamin K (phytonadione) reverses its effects.
• Patient Guidance:
  • Keep vitamin K intake stable by avoiding sudden large increases of green leafy vegetables.
  • Attend scheduled blood tests to monitor INR.
  • Be aware of bleeding signs such as bleeding gums, easy bruising, or black, tarry stools.

Summary of Key High-Risk Medications

Medication	Primary Risk	Monitoring Parameters	Reversal Agent
Heparin	Risk of excessive bleeding	aPTT (activated partial thromboplastin time)	Protamine sulfate
Insulin	Danger of low blood sugar	Regular blood glucose testing	Oral glucose or glucagon
Digoxin	Toxic effects like slow heart rate and irregular rhythms	Digoxin serum levels, potassium levels	Digoxin-specific antibody fragments
Warfarin	Increased bleeding tendency	PT/INR (prothrombin time/international normalized ratio)	Vitamin K

Drug Side Effects, Adverse Reactions, and Interactions

41.1 Definitions

• Side Effects: Expected, usually mild reactions from a medication; often manageable (e.g., drowsiness from antihistamines).
• Adverse Reactions: Harmful and unintended responses that may be serious enough to stop the drug or require treatment (e.g., severe allergic rash, anaphylactic shock).
• Drug Interactions: Changes in a drug’s effect caused by another substance such as medications, foods, or herbal supplements.

41.2 Identifying and Managing Adverse Reactions

• Observation: Keep track of vital signs, laboratory results, mental status, and skin condition for any changes.
• Reporting: Document the reaction’s onset, symptoms, and nursing actions taken.
• Alerting: Notify the healthcare provider promptly for serious reactions; complete incident reporting if indicated.

41.3 Typical Interactions

• Drug-to-Drug:
  • Combined effects may enhance (e.g., opioids plus benzodiazepines increase sedation and respiratory depression).
  • Some drugs may block each other’s effects (e.g., naloxone reverses opioids).
• Drug-to-Food:
  • Grapefruit juice can block CYP450 enzymes, raising blood levels of certain drugs like statins and some calcium channel blockers.
  • Large amounts of vitamin K-rich foods can counteract warfarin’s anticoagulant effect.
• Drug-to-Herb:
  • St. John’s Wort may lower the effectiveness of medications such as oral contraceptives, warfarin, and antidepressants by increasing liver enzyme activity.

41.4 Strategies to Prevent Issues

• Medication Review: Always compare new prescriptions against current medications at every care transition.
• Patient Instruction: Advise patients to disclose all medications and supplements they use, including over-the-counter products and herbs.
• Close Observation: Especially important for drugs with a narrow therapeutic margin (e.g., lithium, digoxin).

Medications for Pain Relief (Opioids, NSAIDs, Acetaminophen)

42.1 Opioids

• Examples: Morphine, Hydromorphone, Fentanyl, Oxycodone.
• How They Work: Attach to opioid receptors in the central nervous system to reduce both the sensation and emotional experience of pain.
• Indications: Used for controlling moderate to severe pain, including after surgery and in cancer patients.
• Possible Side Effects: Slowed breathing, constipation, drowsiness, nausea, low blood pressure upon standing, difficulty urinating.
• Nursing Actions:
  • Check respiratory rate before and after giving; withhold if less than 12 breaths per minute in adults.
  • Apply safety measures to prevent falls due to sedation or dizziness.
  • Promote hydration and fiber intake or use stool softeners to avoid constipation.
  • Administer the smallest effective dose for the shortest time.
  • Assess for signs of misuse, dependency, or diversion.

42.2 Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

• Examples: Ibuprofen, Naproxen, Ketorolac, Indomethacin.
• Mechanism: Block COX enzymes (COX-1 and/or COX-2), which reduces the production of prostaglandins responsible for pain and inflammation.
• Uses: Treat mild to moderate pain, reduce fever, and address inflammation, such as in arthritis.
• Adverse Effects: Can cause stomach irritation or bleeding, impair kidney function, and increase the risk of heart problems (especially selective COX-2 inhibitors).
• Nursing Guidelines:
  • Give with food or milk to protect the stomach lining.
  • Watch for signs of gastrointestinal bleeding (e.g., dark stools, vomiting blood).
  • Use cautiously in patients with kidney disease or ulcers.
  • Educate patients not to combine multiple NSAIDs or use alcohol simultaneously.

42.3 Acetaminophen (Paracetamol)

• How It Works: Blocks prostaglandin production mainly in the brain, reducing pain and fever but has minimal effect on inflammation.
• Indications: Used for mild to moderate pain and fever relief.
• Side Effects: Usually safe but can cause liver damage if taken in excess or over a long period.
• Nursing Considerations:
  • Do not exceed the maximum dose (commonly 3–4 grams in 24 hours; follow facility guidelines).
  • Monitor liver enzymes if using high doses for extended periods.
  • Be cautious about hidden acetaminophen in multi-ingredient products like cold or cough medicines.
