Dominate Cardiovascular & Hematology for Exams
The Cardiovascular System is undoubtedly the most important and high-weightage subject in any nursing competitive exam. On our 200th Daily Mock Test, we are covering the foundation of cardiology. This comprehensive quiz includes high-yield MCQs on the Anatomy of the Heart, Cardiac Physiology, and the Conduction System (SA/AV Node).
We have also included essential questions on ECG Basics (PQRST waves), Clotting Factors, and Blood Indices. Clear your concepts regarding heart chambers, valves, and circulation to score high in AIIMS NORCET 2024, RRB Staff Nurse, and NCLEX-RN exams.

Why Cardiovascular & Hematology Topics Are Your Score Boosters
These subjects form the backbone of clinical questions in nursing officer exams:
- Heart structure and conduction test foundational understanding
- Clotting mechanisms and blood indices evaluate lab interpretation
- Cardiac physiology and ECG basics assess emergency response skills
- High-frequency appearance rewards thorough preparation

Essential Concepts You Must Master for Top Ranks
Anatomy of Heart
Quick Fact
Right atrium receives deoxygenated blood from superior/inferior vena cava.
Complete Coverage
Four Chambers
Right atrium → tricuspid valve → right ventricle → pulmonary valve → lungs
Left atrium → mitral valve → left ventricle → aortic valve → body
Major Vessels
Superior/inferior vena cava (deoxygenated), pulmonary artery (to lungs), pulmonary veins (oxygenated), aorta (to body)
Coronary Supply
Right coronary artery (RCA): right atrium/ventricle, SA/AV node
Left coronary artery (LCA): left ventricle, septum
High-yield fact for exams
Left ventricle thickest wall (highest pressure).
Conduction System
Quick Fact
SA node is primary pacemaker (60–100 bpm).
Complete Coverage
Conduction Pathway
SA node → internodal pathways → AV node → bundle of His → bundle branches → Purkinje fibers
Intrinsic Rates
SA node: 60–100
AV node: 40–60
Purkinje: 20–40
Clinical Relevance
Complete heart block: atria and ventricles independent
High-yield fact for exams
AV node delay allows atrial contraction before ventricular.
Clotting Factors
Quick Fact
Factor VIII deficiency = hemophilia A.
Complete Coverage
Coagulation Cascade
Intrinsic (XII, XI, IX, VIII) + extrinsic (VII) → common pathway (X, V, II, I)
Vitamin K Dependent
II, VII, IX, X
Deficiencies
Hemophilia A (VIII), B (IX), vitamin K deficiency (neonatal bleeding)
High-yield fact for exams
PT measures extrinsic pathway.
Cardiac Physiology
Quick Fact
Stroke volume = end-diastolic - end-systolic volume.
Complete Coverage
Cardiac Cycle
Systole: ventricular contraction, Diastole: filling
Cardiac Output
CO = stroke volume × heart rate
Preload/Afterload
Preload: stretch (Frank-Starling), afterload: resistance
High-yield fact for exams
Frank-Starling law: increased preload → increased contractility.
Blood Indices
Quick Fact
MCV normal 80–100 fL.
Complete Coverage
RBC Indices
- MCV: cell volume (micro/normo/macrocytic)
- MCH: hemoglobin per cell
- MCHC: hemoglobin concentration
- RDW: variation in size
Interpretation
Microcytic: iron deficiency, thalassemia
High-yield fact for exams
Low MCV + low ferritin = iron deficiency.
ECG Basics
Quick Fact
P wave = atrial depolarization.
Complete Coverage
Normal Intervals
PR: 0.12–0.20 sec, QRS: <0.12 sec, QT: 0.36–0.44 sec
Waves
P: atrial, QRS: ventricular, T: repolarization
Leads
Limb (I,II,III,aVR,aVL,aVF), chest (V1–V6)
High-yield fact for exams
ST elevation = acute MI.
