    Study Notes

    Administration and Assessment of Pain Management

    • IV morphine should be administered over 4 to 5 minutes to minimize the risk of adverse effects.
    • Minimum expected hourly urinary output for patients on opioid analgesics is 30 ml/hr.
    • Buprenorphine is not recommended for breakthrough pain due to its agonist-antagonist properties which may interfere with other opioids.
    • Fentanyl is the most appropriate medication for managing breakthrough pain in cancer patients already on scheduled morphine.

    Hemodynamics and Nursing Actions

    • Morphine improves hemodynamics by reducing preload, which decreases cardiac workload.
    • If a patient's respiratory rate is below 12/min before administering opioids, the primary nursing action is to withhold medication and notify the doctor.
    • Pain level assessment after hydromorphone administration should occur 30 minutes to 1 hour afterward.

    Patient Safety Considerations

    • Avoid applying heat over a fentanyl transdermal patch, as it increases the rate of absorption, leading to potential overdose.
    • Recommended assessment frequency for urinary retention in fentanyl patch users is every 4-6 hours.
    • For a postpartum client on magnesium sulfate exhibiting somnolence and slow respiration, magnesium toxicity should be suspected, and calcium gluconate prepared.

    Burn Treatment and Pain Management

    • For a child with full-thickness burns covering 45% of the body, the first action should be to administer IV fluids.
    • Flexing knees and hips during a sickle cell crisis can lead to reduced perfusion and increased pain.

    Monitoring and Drug Interactions

    • A decreasing respiratory rate to 12/min while administering morphine is a concerning finding.
    • Flumazenil is used to reverse benzodiazepine toxicity as it specifically counters their effects.
    • Caution is required in cases of corrosive substance ingestion as activated charcoal may worsen damage.

    Opioid Management and Withdrawal

    • Naloxone is the primary medication for reversing opioid-induced respiratory depression.
    • Diazepam is prescribed during alcohol detoxification primarily to minimize withdrawal symptoms.
    • Disulfiram aids in treating alcohol use disorder by producing unpleasant side effects when combined with alcohol.

    Chronic Pain and Neuropathic Pain Management

    • Gabapentin is best suited to manage neuropathic pain in cancer clients.
    • Pain management for metastasis-related somatic pain may include external beam radiation therapy.
    • In chronic cancer pain management, scheduled medication administration at regular intervals is preferred over wait-for-pain approaches.

    Patient-Controlled Analgesia (PCA) and Drug Monitoring

    • Patient-controlled analgesia (PCA) training is critical, emphasizing that only the client should control the PCA system.
    • Clients prescribed carbamazepine with noted tremors should have the provider notified immediately.

    Pain Assessment Techniques

    • For clients unable to self-report pain, observe non-verbal signals and physiological changes for pain assessment.
    • Long-term ibuprofen therapy necessitates vigilance for signs of gastrointestinal bleeding and tinnitus.

    Additional Priority Actions

    • For breakthrough pain in chronic pain clients, immediate action involves consulting a healthcare provider for prescription changes.
    • Monitoring is crucial for clients on warfarin receiving acetaminophen due to potential INR alterations.
    • In chronic kidney disease patients taking fentanyl, closely monitor respiratory rates due to opioid respiratory depression risk.

    Teaching Points for Medication

    • Clients prescribed butorphanol should be taught to report anxiety or restlessness to the provider.
    • Nursing actions for clients on gabapentin include advising against grapefruit juice to prevent increased side effects.
    • Dexamethasone patients should avoid contact with infectious individuals to reduce infection risk due to immune suppression.

    Conclusion

    • Various medications can interact with each other, generating significant risks or altering patients’ response to therapy. Each medication requires tailored monitoring and patient education to ensure safety and efficacy.### Medication Administration and Pharmacology
    • Sumatriptan: Most effective for aborting migraines when taken at the first headache sign.
    • Lidocaine with Epinephrine: Ensure fingers are not tourniqueted to avoid ischemia and gangrene.
    • Calcium Gluconate: Antidote for magnesium toxicity; critical during magnesium sulfate infusion.
    • Atropine: Antidote for bradycardia caused by beta-adrenergic blockers.
    • Opioids and Lorazepam: Combination can increase risk of respiratory depression and sedation.
    • Naloxone in Newborns: Used to reverse opioid-induced respiratory depression from maternal narcotics.
    • Chlordiazepoxide: Preferred for alcohol withdrawal due to its longer half-life.

    Antidotes and Toxicity Management

    • Protamine Sulfate: Antidote for heparin, inactivates its anticoagulant effects.
    • Excess Naloxone: Can reverse respiratory depression but may lead to increased pain if overdosed.
    • Digoxin Immune Fab: Specific antidote for digoxin toxicity; binds to neutralize its effects.
    • Vitamin K: Used to reverse bleeding due to salicylate (aspirin) poisoning by restoring clotting factors.

    Pain Management Strategies

    • WHO Analgesic Ladder: For cancer pain management, follow by adding an opioid for moderate pain if non-opioids and adjuvants fail.
    • Amitriptyline: Effective for managing chronic neuropathic pain; adjuvant medication.
    • Non-communicative Patients: Observing behaviors and physiological changes is most reliable for assessing pain.
    • Continuous Pain Assessment: Critical after surgery to ensure effective pain management.

    Pain Types and Patient Scenarios

    • Acute Pain: Protective, temporary, typically resolved with healing (e.g., post-surgery).
    • Chronic Pain: Ongoing pain that persists beyond normal healing time; examples include chronic arthritis and cancer pain.
    • Neuropathic Pain: Intense burning or tingling pain from nerve damage (e.g., diabetic neuropathy).
    • Referred Pain: Pain felt in a different area; for example, referred shoulder pain from appendicitis.

    Interventional Strategies

    • Intrathecal Pain Pump: Effective for refractory pain; delivers medication directly to spinal cord.
    • External Beam Radiation Therapy: Reduces tumor size to alleviate somatic pain for cancer patients.

    Medication Monitoring and Precautions

    • Acetaminophen Administration: Ensure total daily dose does not exceed 4 g to avoid toxicity.
    • Patient-Controlled Analgesia (PCA): Only the patient should activate the PCA button to prevent overdose.
    • Nausea Management: Common side effect of opioids; administer antiemetics as needed for relief.
    • Opioid Risk Monitoring: Monitor for respiratory depression and orthostatic hypotension when administering opioids.

    Patient Education and Considerations

    • Ibuprofen: Instruct clients to watch for tinnitus and gastrointestinal bleeding.
    • Oxycodone: Advise monitoring for respiratory depression and orthostatic hypotension.
    • Medication Compliance: Ensure acetaminophen is taken with food to avoid gastrointestinal upset.
    • History of Seizures: Always consider contraindications when prescribing medications for neuropathic pain.### Medications and Their Effects on Patients
    • Amitriptyline: Increases seizure risk; contraindicated for individuals with a history of seizures.
    • Gabapentin: Can cause hypoglycemia and affect electrolyte levels; monitor via a basic metabolic panel.
    • Venlafaxine: May lower seizure threshold and increase suicide risk; essential to assess suicidal ideation in patients.
    • Carbamazepine: Can lead to neurologic side effects; should report tremors immediately. Also increases white blood cell count.
    • Dexamethasone: Requires gradual dosage reduction to avoid withdrawal.
    • Prednisolone: Can cause muscle weakness; important to assess muscle strength.
    • Clonidine: Used for neuropathic pain, can cause hypotension; blood pressure must be monitored closely.
    • Lidocaine (intrathecal infusion): Requires motor function assessments due to potential impairment.
    • Fentanyl (transdermal patch): Patients should monitor for local skin reactions, such as redness or itching.
    • Regional Nerve Block: Watch for complications including respiratory depression, hypertension, and seizures.
    • Epidural Catheter: Assess bowel and bladder functions, motor function, and respiratory rate.

    Nursing Actions and Client Education

    • Clients should report increased pain, severe headaches, or sudden neurological changes, particularly with an epidural catheter in place.
    • Encourage clients to monitor for infection at needle sites when using acupuncture or TENS.
    • Advise patients recovering from surgery to increase protein intake for wound healing; chicken breast is an example of a complete protein.
    • Provide privacy during relaxation techniques to enhance effectiveness and comfort.
    • For a patient with hypotension after a nerve block, increase IV fluids to manage peripheral vasodilation effects.

    Nutritional Considerations

    • Chronic diarrhea can lead to deficiencies in fat-soluble vitamins (A, D, E, K).
    • Types of fatty acids beneficial for cardiovascular health include omega-3, omega-6, and monounsaturated fatty acids—these can improve lipid profiles and reduce inflammation.
    • Patients with type 2 diabetes should focus on complex carbohydrates (starch and fiber) to regulate blood glucose levels.

    Vitamin Deficiencies and Risks

    • B-complex Vitamins:
      • Alcohol abuse increases the risk of deficiencies in thiamin, riboflavin, and niacin.
      • Vitamin B12 is essential for the utilization of folate; deficiency in B12 can impair folate's effectiveness.
    • Fat-soluble Vitamins:
      • Cystic fibrosis patients are at risk for deficiencies in vitamins A, D, E, and K due to malabsorption.
      • Vitamin A toxicity can occur with excessive supplementation and is characterized by headaches and blurred vision.

    Special Considerations for Dietary Restrictions

    • Vegans are particularly at risk for vitamin B12 deficiency, which can lead to severe health issues if not supplemented or fortified.
    • Niacin deficiency symptoms include dermatitis, diarrhea, and dementia, commonly termed the "three D's" of pellagra.

    Conclusion

    • Regular monitoring and education on medication effects, dietary intake, and vitamin needs are crucial to patient health and recovery, particularly among populations at risk for deficiencies.

    Respiratory Diagnostic Procedures

    • Evaluates respiratory status by assessing blood oxygenation, lung function, and airway integrity.
    • Common procedures include pulmonary function tests, arterial blood gases, bronchoscopy, and thoracentesis.
    • Informed consent must be obtained prior to any diagnostic procedure.

    Pulmonary Function Tests (PFTs)

    • Assess lung function including volumes, capacities, diffusion capacity, and flow rates.
    • Important for diagnosing lung diseases and evaluating respiratory risk before surgery.
    • Smoking cessation required for 6-8 hours prior to testing; withhold inhalers for 4-6 hours.

    Arterial Blood Gases (ABGs)

    • Evaluates oxygenation and acid-base balance of the blood.
    • Measures essential parameters: pH, PaO2, PaCO2, HCO3¯, and SaO2.
    • Can be obtained via arterial puncture or arterial line.

    Indications for ABGs

    • Helps monitor treatment effects (e.g., for acidosis) and guide oxygen therapy.
    • Abnormal blood pH can indicate respiratory, metabolic, or renal conditions.

    ABG Collection Procedures

    • Preprocedure: Use a heparinized syringe; perform Allen’s test to ensure circulation.
    • Intraprocedure: Use aseptic technique for arterial puncture and transport samples to lab on ice.
    • Postprocedure: Apply direct pressure to the site for at least 5 minutes; longer if on anticoagulants, and monitor for bleeding or pulse loss.

    Interpretation of ABGs

    • Normal pH: 7.35 to 7.45; acidosis is <7.35, alkalosis is >7.45.
    • Reference ranges:
      • PaO2: 80 to 100 mm Hg
      • PaCO2: 35 to 45 mm Hg
      • HCO3¯: 21 to 28 mEq/L
      • SaO2: 95% to 100%

    Complications of ABG Collection

    • Hematoma and arterial occlusion; monitor for symptoms at the puncture site.
    • Air embolism can occur—place client in Trendelenburg position if suspected.

    Bronchoscopy

    • Technique to visualize larynx, trachea, and bronchi; can be done under anesthesia.
    • Used for diagnosis (tumors, biopsies) and therapeutic interventions (removal of foreign bodies, secretions).
    • Must ensure informed consent and monitor for respiratory complications post-procedure.

    Thoracentesis

    • Procedure to remove fluid or air from pleural space for diagnosis or relief.
    • Performed under local anesthesia; ultrasound may assist in guiding needle placement.
    • Large volume fluid removal is limited to mitigate the risk of pulmonary edema.

    Indications and Assessments for Thoracentesis

    • Diagnoses pleural effusion causes: transudates or exudates due to various medical conditions.
    • Clinical signs include pain, shortness of breath, abnormal lung sounds, and dull percussion.

    Pre- and Postprocedure Nursing Actions for Thoracentesis

    • Preprocedure: Confirm informed consent, prepare supplies, and position the client for optimal access.
    • Intraprocedure: Monitor vital signs, ensure sterile technique, and label samples accurately.
    • Postprocedure: Dress the puncture site, monitor for respiratory function and potential complications.

    Potential Complications of Thoracentesis

    • Mediastinal shift, pneumothorax, bleeding, and infection; monitor vital signs and lung sounds.
    • Recognize pneumothorax symptoms: diminished breath sounds, chest wall asymmetry, respiratory distress.

    Body Fluids and Dehydration

    • 55% to 60% of body weight consists of fluid; this decreases in older adults due to physiological changes.
    • Fluid compartments include intracellular (ICF) and extracellular (ECF); ECF is further divided into intravascular, interstitial, and transcellular fluids.
