PREVIOUS EXAM - 4 (LOOK AT OLD NOTES !!!!) Insulin peaks Is min ○ For short-acting insulin, check blood glucose around 1000-1100. - ○ For long-acting insulin, you can check blood glucose at regular intervals through the day, but there’s no specific peak time to monitor. - - - - & Dressing ○ Date time initial Chest tube ○ Monitor the Drainage System Water seal chamber: Acts as a one-way valve to let air out, but not back in. ○ TIDALING: Normal. bubble , pause, bubble , ○ Continuous bubbling: May indicate an air leak. pause - > wlbreathing Suction control chamber (if ordered): Usually filled with sterile water or uses wall suction to help pull out air/fluid. Assess Drainage Color, amount, and consistency: ○ Report >100 mL/hr of blood (post-op), sudden bright red, or * cloudy/purulent drainage. Mark and time output on the chamber regularly Keep It Below the Chest ○ Always keep the drainage system upright and below chest level to promote drainage by gravity. ○ Do not lift or clamp tubing unless ordered Maintain Dressing and Insertion Site ○ Keep the dressing occlusive (airtight), dry, and intact. ○ Monitor for signs of infection: redness, swelling, drainage, fever. ○ Check for subcutaneous emphysema (air under the skin, feels like Rice* Krispies). Emergency Situations ○ If the tube gets pulled out: → Immediately cover the site with a sterile occlusive dressing (like petroleum gauze), tape on 3 sides to allow air to escape but not enter. - ○ If the system breaks: → Place the chest tube end in sterile water to create a temporary water seal Patient Care ○ Encourage deep breathing, coughing, and incentive spirometry to help lung expansion. ○ Reposition as needed, but don’t clamp the tube unless ordered.

Heart Anatomy & Physiology – Know the Flow 4 Chambers: Right atrium → Right ventricle → Lungs Left atrium → Left ventricle → Body Valves: Tricuspid (RA → RV), Pulmonic, Mitral (LA → LV), Aortic Blood Flow Mnemonic: "Toilet Paper My Ass" = Tricuspid, Pulmonic, Mitral, Aortic RA-RV- > Lungs > LAtLV-tissues - Electrical Conduction System: SA node (pacemaker, 60–100 bpm) → AV node (slows down and allows ventricles to fill before contracting, 40–60 bpm) → Bundle of His → Purkinje fibers (stimulate ventricular contraction) Perfusion Basics: CO = HR x SV Normal EF (Ejection Fraction) = 55–70% Deoxygenated blood flows from the body into the right atrium, passes through the tricuspid valve to the right ventricle, and then to the lungs via the pulmonary artery for oxygenation. Oxygenated blood returns to the left atrium, passes through the mitral valve into the left ventricle, and is pumped through the aorta to supply the body. A – Assessment A Vitals, heart sounds (S3 = CHF!), edema, JVD, lung sounds (crackles), perfusion (cap refill), fatigue, chest pain, dyspnea. HX and modifiable risk factors D – Diagnosis Decreased cardiac output Impaired gas exchange Fluid volume excess Activity intolerance P – Planning Improve oxygenation & cardiac output Reduce fluid overload Promote rest and activity balance Prevent complications (dysrhythmias) I – Intervention Daily weights, I&Os Administer meds: ○ Antihypertensives (Lisinopril, Metoprolol) Reduce blood pressure to prevent damage to heart and blood vessels. ○ Diuretics (Furosemide): Reduce fluid overload in heart failure by increasing urine output. ○ Anticoagulants (Warfarin, Heparin): Prevent blood clot formation, reducing the risk of stroke/MI ○ Antiarrhythmics (Amiodarone): Used to manage arrhythmias and maintain normal heart rhythm. ○ Statins (Atorvastatin): Lower cholesterol levels to prevent atherosclerosis and reduce the risk of coronary artery disease. ○ Nitrates (Nitroglycerin): Vasodilators that relieve angina by increasing blood flow to the heart muscle. ○ Beta-Blockers (Metoprolol): Decrease heart rate and blood pressure, reducing the workload on the heart.

Treatment: ○ Long-term IV antibiotics ○ Surgery may be needed if there is valve damage or persistent infection. Angina Pectoris Definition ○ Chest pain or discomfort due to inadequate oxygen supply to the ○ heart muscle (myocardial ischemia). Types: ○ Stable Angina: Occurs with exertion and relieved by rest or nitroglycerin. ○ Unstable Angina: Occurs at rest, more severe, and not relieved by nitroglycerin; may indicate impending myocardial infarction. Signs and Symptoms: ○ Chest pain or pressure, often described as squeezing, heaviness, or burning. ○ Pain may radiate to the neck, jaw, shoulder, or arm. ○ Dyspnea, sweating, nausea. Diagnosis: ○ ECG, stress testing, and coronary angiography. Treatment: ○ Nitroglycerin to relieve pain. ○ Antiplatelets (aspirin) to reduce clotting risk. ○ Beta-blockers and calcium channel blockers to reduce heart workload. Congenital Heart Defects (CHD) Definition: Structural abnormalities in the heart present from birth that affect blood flow. Examples: ○ Atrial Septal Defect (ASD), Ventricular Septal Defect (VSD), Tetralogy of Fallot, Patent Ductus Arteriosus (PDA).

The liver frailty index, which includes grip strength, chair stands, and balance. Key interventions to improve frailty include proper nutrition and moderate exercise, areas where nurses can play a key role. Frailty increases the risk of falls, which is also associated with hepatic encephalopathy. Nurses should identify patients at higher risk of falls and discuss preventive strategies with patients and caregivers. Counselling about healthy lifestyle, diet, and self-management ○ Nutritional counseling is crucial for patients with cirrhosis due to common issues like sarcopenia, frailty, and the need to reduce sodium intake in those with ascites or edema. A multidisciplinary team is essential to help ensure patients meet the goals of adequate calorie and protein intake. Nursing role in management of complications of cirrhosis ○ Nurses play a key role in caring for hospitalized patients with decompensated cirrhosis by conducting thorough assessments. This includes monitoring signs of disease progression (e.g., fluid buildup, jaundice), preventing risks (e.g., delirium, malnutrition), and addressing symptoms like pain, breathlessness, and anxiety. Understanding the patient's experience, including psychosocial factors such as fears and increased dependence, is essential for comprehensive care The role of specialist nurses in liver diseases NURSING CARE OF PATIENTS WITH COMPENSATED CIRRHOSIS L cirrhosis in the absence of ascites, variceal bleeding, or hepatic encephalopathy Diet education: High protein, low fat, moderate sodium and increased fiber. Encourage moderate exercise. Immunizations: review immunization history and perform hepatitis A & B titers Mandatory immunizations include COVID-19 Pneumococcal pneumonia Influenza Tetanus Medication Education: Pt is advised to avoid NSAIDs, aspirin, and acetaminophen Screening: The nurses role includes scheduling screenings and surveillance during an endoscopy Counselling about healthy diet and lifestyle ○ focusing on high protein, low fat, low/moderate sodium, and increased fiber. ○ Nurses should encourage moderate exercise as physical activity can help prevent sarcopenia and improve the progression of cirrhosis. Education about cirrhosis and its potential complications ○ Providing education can help patients and caregivers recognize complications early and seek medical attention. One key complication, variceal hemorrhage, can be effectively prevented with beta-blockers or endoscopic variceal band ligation. Assisting in treating the cause of cirrhosis ○ For alcohol-related cirrhosis, nursing interventions in primary care can support patients in achieving abstinence and adhering to alcohol dependence treatments, such as acamprosate. Nurses should also collaborate with alcohol treatment facilities and address social stigma. For non-alcoholic fatty liver disease, nurses should focus on encouraging weight loss and addressing stigma related to being overweight. A Mediterranean or plant-based diet, reduced caloric intake, and an* exercise program can help achieve a weight loss of over 10%, improving liver health by reducing steatosis, inflammation, and fibrosis. Screening for gastroesophageal hepatocellular carcinoma ○ Endoscopy should be performed at the time of initial diagnosis of cirrhosis. If no mem - varices are found, a follow-up endoscopy should be done in 3 years. For small varices, a repeat endoscopy should be scheduled in 1 to 2 years. Non-selective beta-blockers should be prescribed for patients with small or large varices, unless contraindicated. Nurses play a key role in educating patients on how to monitor beta-blocker therapy, including tracking resting heart rate and blood pressure, and informing them about potential side effects like hypotension, dizziness, and cold extremities. Immunization ○ Mandatory vaccines for patients include COVID-19, pneumococcal pneumonia, influenza, and tetanus. Serologic testing for hepatitis A and B should be done to check for previous exposure, and the respective vaccines should be administered if the patient is negative for anti-HAV and anti-HBc antibodies. Medication counseling ○ Nurses play a crucial role in reviewing medications and improving medication adherence during both initial and follow-up visits, including via telehealth. Patients should be advised to avoid NSAIDs and aspirin, and use acetaminophen (up to 2g daily) as an alternative. Patients with active alcohol use should be informed of the increased risk of liver toxicity with acetaminophen. Fluoroquinolones, penicillins, and cephalosporins are generally safe antibiotics, and statins at lower doses, along with oral hypoglycemic agents or insulin for diabetes, are acceptable. Caring for comorbidities ○ Comorbidities may include features of the metabolic syndrome, namely obesity, diabetes, hypertension, and cardiovascular disease. This section is a reminder about the liver and its physiological functions including metabolic, hematologic, and production of bile. Think about functions such as blood volume reservoir, blood filter, blood clotting factors, and drug metabolism and detoxification. Anatomy: Largest internal organ, located in RUQ under the diaphragm. Made of lobes; functional units = lobules. Gets blood from the hepatic artery (oxygen) and portal vein (nutrients from GI tract). Physiology: Metabolism of carbs, proteins, fats. Detoxifies meds and toxins. Produces bile → helps digest fats. Synthesizes albumin & clotting factors. Stores vitamins A, D, E, K, and B12. Converts ammonia → urea for excretion. Nursing Process for Liver Disease Assessment: Fatigue, jaundice, ascites, RUQ pain, bleeding. ↑ Labs: ↑ AST/ALT, bilirubin Vitamin K & ○ ammonia; ↓ albumin, platelets. Diagnosis: Risk for bleeding, Imbalanced nutrition, Excess fluid volume, Impaired skin integrity. Planning/Intervention: Monitor labs & weight. Low-sodium, high-calorie, low-protein (if ammonia ↑). * Administer lactulose (↓ ammonia), diuretics, vit K.* Evaluation: Improved energy, labs stabilizing, less ascites, ammonia levels down. Diagnostic Testing for Liver LFTs: AST, ALT, ALP, bilirubin, albumin. ○ ALT = liver damage specific to the liver * ○ AST = liver damage specific for other organs like heart kidneys pancreas brain* PT/INR: prolonged if the liver is damaged > blood isn’t clotting quick enough Ammonia: ↑ with hepatic encephalopathy. Ultrasound: check structure. CT/MRI: tumor, abscess, cirrhosis.

Fatty Liver Disease (NAFLD/NASH): an accumulation of fat in the liver in individuals who consume little to no alcohol. This fat buildup leads to inflammation and liver cell damage, a condition known as non-alcoholic steatohepatitis (NASH), which is a more severe form of NAFLD and has a higher risk of progressing to cirrhosis. Assessment: NAFLD - NASH yairr. Often asymptomatic, may present with mild fatigue, discomfort in RUQ ○ Risk factors: Obesity, diabetes, hyperlipidemia Labs: Elevated liver enzymes (ALT, AST), insulin resistance ○ Nursing Interventions: Promote weight loss: Encourage a healthy diet (Mediterranean/plant-based), exercise Manage comorbidities: Diabetes, hyperlipidemia Educate: Avoid alcohol, lifestyle modifications 4.

Control DM, cholesterol. Nurses: education & monitoring labs. Alcoholic Liver Disease Stop alcohol completely. Vitamins: thiamine, folate. Possible detox support, social work, psych. Nurses: Monitor for withdrawal, bleeding, nutrition. Team includes: GI, hepatology, dietitian, pharmacist, psych, social work. The article titled "From NAFLD to MAFLD: Nurse and Allied Health Perspective," authored by Michelle Clayton and colleagues, discusses the renaming of non-alcoholic fatty liver disease (NAFLD) to metabolic (dysfunction) associated fatty liver disease (MAFLD). This change aims to better reflect the disease's association with metabolic dysfunction. The authors, including nurse and allied health practitioners, express support for this redefinition, believing it will enhance nurse-patient communication, improve patient care, and reduce healthcare system burdens Ideally, going for-ward, the change to MAFLD would improve the dialogue between treating healthcare professionals and patients and may help bridge the gap (health literacy), with increase awareness of MAFLD will continue to improve among providers and the public, so that patients can be risk strati-fied and appropriately counselled on interventions that are likely to improve metabolic and liver health. ○ CV HEALTH Unlike NAFLD, which defines fatty liver disease by the absence of alcohol use, MAFLD shifts the focus to the metabolic factors that contribute to liver disease. Clinical Manifestations & Management of Cirrhosis Manifestations: Jaundice, ascites, spider angiomas, varices, fatigue. Decompensated signs: hepatic encephalopathy (confusion, asterixis: flapping tremor), GI bleed, edema, hepatorenal syndrome. Management: Lactulose for ammonia. ○ Lactulose is also used to reduce the amount of ammonia in the blood of patients with liver disease. It works by drawing ammonia from the blood into the colon where it is removed from the body. Diuretics (spironolactone). ascites Paracentesis for ascites. Beta-blockers to prevent variceal bleeding. treats portalin ○ By lowering portal pressure and reducing the risk of varices becoming distended and fragile, beta-blockers help prevent variceal bleeding, which can be life-threatening. Nutrition: low sodium, soft protein if encephalopathy. ○ A low-sodium diet helps control ascites and edema, and protein management is critical in controlling ammonia levels and preventing further brain impairment. Ethical Dilemmas in Liver Transplant Arises from issues related to limited organ availability and prioritization criteria, substance abuse hx, adherence to post-transplant care, resource allocation, and decisions aggressive treatment, and palliative care Dilemmas: Who qualifies for a transplant? (e.g., former alcohol use, relapse risk). Limited organs vs. high demand. Equity in access (insurance, social factors). Nursing Role: Advocate for fair access. Participate in transplant research to improve outcomes. LIVER end Post-Liver Transplant: Can the Client Self-Care? ARE THEY GONNA STOP THE BEHAVIORS THAT CAUSED THEM TO LOSE THEIR LIVER IN THE FIRST PLACE? AND CAN THEY TAKE CARE OF THAT ORGAN? Alcoholism should not define someone’s lives especially young It is not about judgement This involves adhering to medication regimens, attending regular follow-up appointments, maintaining a healthy lifestyle, and being vigilant about signs of organ rejection or infection. Post-transplant care includes: Lifelong immunosuppressants → must take exactly as ordered. Infection prevention (hand hygiene, avoid crowds). immunocompromised Regular labs & appointments.

Parkinson’s disease progression: As Parkinson’s disease progresses, it contributes to orthostatic hypotension or elevated blood pressure. Medication side effects: Some medications used to manage Parkinson’s disease (e.g., levodopa) may contribute to elevated blood pressure or interfere with its regulation. Environmental stressors: The change in living environment, such as moving into the nursing home, can be a stressor that might elevate blood pressure. Pain or discomfort: Parkinson’s disease can lead to muscle stiffness or discomfort, which can contribute to elevated blood pressure. Dehydration or lack of proper nutrition: These could also be factors, especially with the recent change in environment and care. What things can you assess with Joshua to get more information about his current state? Orthostatic blood pressure measurements: Measure his blood pressure in both lying and standing positions to assess for orthostatic hypotension, which is common in Parkinson’s disease. Heart rate and rhythm: Take his pulse to assess for irregularities, as Parkinson’s can sometimes cause arrhythmias. Symptoms of dizziness or lightheadedness: Ask Joshua about any episodes of dizziness, which may suggest orthostatic hypotension or medication side effects. Pain assessment: Given that Parkinson’s disease causes muscle rigidity, assess for pain or discomfort that could elevate his blood pressure. Medication review: Review his current medications for any that might be contributing to the elevated blood pressure or causing adverse effects. What nonpharmacological steps can Joshua take to lower his blood pressure? Dietary changes: Encourage a heart-healthy diet, such as the DASH (Dietary Approaches to Stop Hypertension) diet, which emphasizes fruits, vegetables, whole grains, and low-fat dairy. Physical activity: Encourage regular, light physical activity that is safe for his mobility, such as walking or chair exercises, which can help manage blood pressure. Stress management: Techniques like deep breathing, meditation, or guided relaxation may help reduce stress, a potential contributor to elevated blood pressure. Adequate hydration and nutrition: Ensure that he is drinking enough fluids and receiving proper nutrition to avoid dehydration, which can affect blood pressure regulation. Regular monitoring of blood pressure: Encourage frequent blood pressure checks to track any changes and adjust interventions accordingly. What general information will you share with Joshua’s family to promote his CV health? Regular blood pressure monitoring: Emphasize the importance of monitoring Joshua’s blood pressure regularly to identify any changes or trends. Diet and nutrition: Share information about the importance of a low-sodium, high-potassium diet and encourage heart-healthy food choices to support cardiovascular health. Physical activity: Discuss the importance of maintaining physical activity within his abilities, as it helps control blood pressure and improves overall well-being. Medication adherence: Explain the role of prescribed medications for managing blood pressure and the importance of compliance, if Joshua changes his mind about taking medications. Stress management techniques: Offer guidance on relaxation and stress-reduction strategies to help lower his blood pressure. Symptom recognition: Educate his family on symptoms of high or low blood pressure, including dizziness, headaches, or fainting, so they can be vigilant and intervene appropriately. Amyotrophic Lateral Sclerosis (ALS) Definition: A progressive neurodegenerative disease that affects motor neurons, leading to muscle weakness and atrophy. Signs and Symptoms (S/S): ○ Muscle weakness, twitching, spasticity, and eventual loss of motor control. ○ Difficulty speaking, swallowing, and breathing ○ Cognitive function is typically unaffected. Interventions: ○ Provide assistive devices for mobility and communication as needed. ○ Support respiratory function, often with non-invasive ventilation. ○ Educate family on progressive nature of ALS and prepare for end-of-life decisions. Riluzole: Slows disease progression slightly. no cure , just slow it Edaravone: May slow progression in some patients. Symptomatic management: Pt will diefrom ALS. ○ Includes muscle relaxants for spasticity and medications for pain management.atsomepoint Medications ○ Stroke: tPA: For ischemic stroke if given within the therapeutic window to dissolve clots. Antiplatelet agents (e.g., aspirin) and anticoagulants (e.g., warfarin) to prevent future clots in ischemic stroke. ○ Antihypertensives: For hemorrhagic stroke to manage blood pressure. Reduction of Risk Potential (RRP) Focus: Prevent complications or deterioration in clinical settings. Tips: Memorize early vs late signs of complications ○ hypoxia = restlessness first, cyanosis later). Flashcards for tubes/drains/wounds – what's normal output for a chest tube? What does cloudy urine mean? Physiological Adaptation Tips: Practice linking symptoms + pathophysiology + priority intervention. → Ex: CHF = fluid overload → crackles/SOB → furosemide & elevate HOB. Review ABGs, acid-base, ventilator settings, and ICP/CVP values. Go over med-surg “zebras” like SIADH vs. DI, Addison’s vs. Cushing’s. Health Promotion & Maintenance Focus: Prevention, screenings, growth/development, vaccines, education. Tips: Know your immunization schedule (e.g., DTaP, MMR, HPV, flu). Use growth/development mnemonics for kids (Erikson, milestones). Screening ages: mammogram = 40, colonoscopy = 45, PSA = 50. Teach lifestyle changes in simple terms: low-sodium diet, smoking cessation, exercise. Match education to the client’s developmental level (you wouldn’t teach a toddler the same way as a teen). Psychosocial Integrity Focus: Coping, mental health, therapeutic communication, grief, abuse. Learn stages of grief and appropriate nursing responses for each. Know signs of abuse, neglect, or trauma—and when/what to report. Be present, not prescriptive.” The patient needs support more than solutions.
