Master Cardiovascular System for Your 2025 Nursing Exams
Hello, dear nursing students and exam aspirants. We are continuing our journey to help you prepare for the AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM nursing exams in 2025. Today, on Day 31, we will focus on the Cardiovascular System, a topic you need to master. Cardiovascular nursing involves caring for patients with heart and blood vessel conditions, understanding diagnostic tools like ECG and coronary angiography, and managing diseases like hypertension. At logyanlo.in, we are here to support you with our Day 31 Practice Test, designed to help you excel in this essential subject.
In this guide, we will cover the Cardiovascular System in detail, including ECG (normal and abnormal findings), Coronary Angiography, Hypertension, Cor Pulmonale, and Arteriosclerosis & Atherosclerosis. These topics are high-yield for exams like AIIMS NORCET 9.0, KGMU, and Raj CHO/NHM, often making up 12–15% of the questions. Let us dive in and take your exam prep to the next level.
Why Cardiovascular System is Essential for Nursing Exams
Cardiovascular System nursing focuses on the care of patients with heart and vascular disorders, requiring a deep understanding of diagnostic procedures and disease management. This topic is a major focus in exams like AIIMS NORCET 9.0, KGMU, BTSC, and Raj CHO/NHM, testing your knowledge of ECG interpretation, hypertension management, and conditions like atherosclerosis. Here is why this subject matters:
- Core Knowledge: It covers diagnostic tools like ECG and coronary angiography, and conditions like cor pulmonale.
- Exam Focus: Questions often test your ability to identify abnormal ECG findings and manage hypertension.
- Clinical Skills: Skills like monitoring cardiac status and educating patients on lifestyle changes are vital in cardiovascular nursing.
- Score Booster: A strong performance in this section can significantly improve your overall exam score.
At logyanlo.in, our Day 31 Practice Test is crafted to help you master these concepts and feel confident heading into the 2025 exams.
Key Concepts in Cardiovascular System for Your Exam Prep
Let us explore the core topics of the Cardiovascular System that you need to know for your AIIMS NORCET 9.0, KGMU, BTSC, or Raj CHO/NHM exams. We will focus on nursing responsibilities and exam-relevant points.
ECG: Normal & Abnormal
Electrocardiogram (ECG) is a diagnostic tool that records the electrical activity of the heart.
Normal ECG:
- P Wave: Atrial depolarization, duration <0.12 seconds.
- QRS Complex: Ventricular depolarization, duration 0.06–0.10 seconds.
- T Wave: Ventricular repolarization.
- PR Interval: 0.12–0.20 seconds (time from atrial to ventricular depolarization).
- QT Interval: 0.36–0.44 seconds (total ventricular activity).
- Normal heart rate: 60–100 beats/min, regular rhythm.
Abnormal ECG:
- Myocardial Infarction (MI):
- ST elevation, Q waves in affected leads (e.g., V1–V4 for anterior MI).
- Indicates blocked coronary artery.
- Atrial Fibrillation:
- Irregular rhythm, absent P waves, irregular QRS.
- Risk of thromboembolism (e.g., stroke).
- Ventricular Tachycardia:
- Wide QRS complexes, rate >100 beats/min.
- Medical emergency, can lead to cardiac arrest.
- Bradycardia:
- Heart rate <60 beats/min, prolonged PR interval.
- Seen in heart block or beta-blocker overdose.
Nursing Responsibilities:
- Prepare the patient for ECG, ensuring proper lead placement (e.g., V1 at 4th intercostal space, right sternal border).
- Monitor for abnormal findings, like ST elevation, and report immediately.
- Educate patients on the procedure, reassuring them it is non-invasive.
Exams often test your ability to identify ECG abnormalities, like ST elevation in MI.
Coronary Angiography
Coronary Angiography is a diagnostic procedure to visualize coronary arteries using contrast dye and X-rays.
Purpose:
- Detect blockages or narrowing in coronary arteries (e.g., in angina or MI).
- Guide interventions like angioplasty or stent placement.
Procedure:
- Catheter inserted via femoral or radial artery, advanced to coronary arteries.
- Contrast dye injected, X-ray images taken to identify blockages.
- Post-procedure: Monitor puncture site for bleeding, ensure bed rest for 4–6 hours.
Risks:
- Bleeding or hematoma at puncture site.
- Allergic reaction to contrast dye.
- Coronary artery dissection (rare).
Nursing Responsibilities:
- Pre-procedure: Check for allergies to contrast dye, ensure NPO status for 6–8 hours.
- Post-procedure: Monitor vital signs, assess puncture site for bleeding, and ensure bed rest.
- Educate patients on signs of complications, like swelling or severe pain at the site.
Exams often test your knowledge of nursing care for coronary angiography, like monitoring for bleeding.
Hypertension
Hypertension is persistently elevated blood pressure, a major risk factor for cardiovascular disease.
Classification:
- Normal: <120/80 mmHg.
- Prehypertension: 120–139/80–89 mmHg.
- Stage 1 Hypertension: 140–159/90–99 mmHg.
- Stage 2 Hypertension: ≥160/100 mmHg.
- Hypertensive Crisis: >180/120 mmHg (medical emergency).
Causes:
- Primary (Essential): 90–95% of cases, linked to genetics, obesity, stress.
- Secondary: 5–10% of cases, due to kidney disease, adrenal disorders.
Symptoms:
- Often asymptomatic (“silent killer”).
- Headache, dizziness, blurred vision in severe cases.
- Complications: Stroke, heart failure, kidney damage.
Management:
- Lifestyle: Low-sodium diet, exercise, weight loss, stress management.
- Medications: ACE inhibitors (e.g., lisinopril), beta-blockers (e.g., atenolol), diuretics.
Nursing Responsibilities:
- Measure BP accurately, using the correct cuff size and ensuring the patient is relaxed.
- Educate patients on lifestyle changes, like reducing salt intake to <2,300 mg/day.
- Monitor for side effects of medications, like cough with ACE inhibitors.
Exams often test your knowledge of hypertension stages, like Stage 2 being ≥160/100 mmHg.
Cor Pulmonale
Cor Pulmonale is right-sided heart failure due to chronic lung disease and pulmonary hypertension.
Causes:
- Chronic obstructive pulmonary disease (COPD) (most common).
- Pulmonary embolism, interstitial lung disease.
- Leads to increased pulmonary artery pressure, straining the right ventricle.
Symptoms:
- Dyspnea (shortness of breath), fatigue.
- Peripheral edema, jugular vein distension (JVD).
- Cyanosis (bluish lips/skin) due to hypoxia.
Management:
- Treat underlying lung disease (e.g., bronchodilators for COPD).
- Oxygen therapy to improve hypoxia.
- Diuretics to reduce fluid overload (e.g., furosemide).
Nursing Responsibilities:
- Monitor respiratory status, noting dyspnea or cyanosis, and administer oxygen as ordered.
- Assess for signs of right heart failure, like JVD or edema, and report promptly.
- Educate patients on managing lung disease, like smoking cessation in COPD.
Exams often test your understanding of cor pulmonale causes, like its link to COPD.
Arteriosclerosis & Atherosclerosis
Arteriosclerosis is the hardening of arteries, while atherosclerosis is a type of arteriosclerosis involving plaque buildup.
Arteriosclerosis:
- General thickening and stiffening of arterial walls.
- Caused by aging, hypertension, diabetes.
- Leads to reduced elasticity, increasing BP.
Atherosclerosis:
- Plaque (cholesterol, fat, calcium) buildup in arteries.
- Risk factors: High LDL, smoking, obesity, sedentary lifestyle.
- Complications: Coronary artery disease (CAD), peripheral artery disease (PAD), stroke.
Symptoms:
- Often asymptomatic until significant blockage.
- Angina (chest pain) in CAD, claudication (leg pain) in PAD.
- Signs of complications: MI, stroke.
Management:
- Lifestyle: Low-fat diet, exercise, smoking cessation.
- Medications: Statins (e.g., atorvastatin) to lower cholesterol, antiplatelets (e.g., aspirin).
- Surgical: Angioplasty or bypass surgery for severe blockages.
Nursing Responsibilities:
- Assess for signs of reduced perfusion, like chest pain or weak peripheral pulses.
- Educate patients on risk factor modification, like adopting a Mediterranean diet.
- Monitor lipid profiles, ensuring LDL <100 mg/dL in high-risk patients.
Exams often test your knowledge of atherosclerosis risk factors, like smoking and high LDL.
