Leukemia, Sickle Cell & Heart Defects (TOF) MCQs | Med-Surg & Pediatric Nursing for NCLEX & NORCET

Elevate Your Cardiovascular & Hematological Mastery for Exams

Hematological and Cardiovascular disorders are high-weightage topics in both Medical-Surgical and Child Health Nursing. In today's mock test, we cover critical blood disorders like Leukemia, Sickle Cell Disease, Thalassemia, and Hemophilia.

We also focus on congenital and acquired heart defects, specifically Tetralogy of Fallot (TOF), Coarctation of the Aorta, and Mitral Stenosis. These solved questions on Hematopoiesis and disease management are essential for AIIMS NORCET, NCLEX-RN, and Staff Nurse preparation. Download your free PDF below and take a confident step toward your top rank!

Why Cardiovascular & Hematological Disorders Are Your Exam Powerhouse

These disorders form a cornerstone of both adult and child health nursing questions:

• Congenital heart defects like TOF and coarctation test early recognition and intervention
• Hematological conditions such as hemophilia and leukemia evaluate bleeding and oncology care
• Mitral stenosis and sickle cell disease assess chronic management and complication prevention
• These high-frequency topics reward candidates with strong pathophysiology and nursing knowledge
  logyanlo.in delivers solved rationale-based content to transform these areas into your scoring advantage!

Deep-Dive Concepts You Must Master for Top Ranks

Mitral Stenosis

Quick Fact

Mitral stenosis is most commonly caused by rheumatic heart disease.

Complete Coverage

Mitral stenosis narrows the mitral valve orifice, obstructing blood flow from left atrium to left ventricle. This leads to increased left atrial pressure, pulmonary congestion, and right heart strain over time.

Pathophysiology in Detail
Rheumatic fever causes scarring and fusion of valve leaflets and chordae tendineae, reducing valve opening. Blood backs up in the left atrium, causing atrial enlargement and pulmonary hypertension.

Clinical Presentation

• Exertional dyspnea, orthopnea, paroxysmal nocturnal dyspnea
• Fatigue, palpitations (atrial fibrillation common)
• Hemoptysis (from ruptured bronchial veins)
• Malar flush, tapping apex beat

Diagnostic Findings

• Loud S1, opening snap, mid-diastolic rumble
• Echocardiography: valve area <1.5 cm² severe
• ECG: left atrial enlargement (P mitrale)

Management

• Diuretics, beta-blockers, anticoagulation (AF)
• Balloon valvuloplasty or valve replacement

Nursing Considerations
Monitor for atrial fibrillation and thromboembolism risk

High-yield fact for exams
Opening snap + rumbling murmur = classic auscultation finding.

Coarctation of Aorta

Quick Fact

Coarctation causes upper limb hypertension with weak femoral pulses.

Complete Coverage

Coarctation of the aorta is a congenital narrowing typically near the ductus arteriosus. This obstruction increases upper body pressure while reducing lower body perfusion.

Pathophysiology
Narrowed segment causes high pressure proximal and low pressure distal to the coarctation. Collateral circulation develops through intercostal arteries.

Clinical Presentation

• Hypertension in arms, weak/delayed femoral pulses
• Rib notching on X-ray from collateral vessels
• Associated with bicuspid aortic valve

Diagnostics
Echocardiography, MRI/CT angiography

Management
Surgical resection or balloon angioplasty

Nursing Considerations
Monitor for post-op hypertension, assess pulses

High-yield fact for exams
Blood pressure higher in arms than legs.

Hematopoiesis

Quick Fact

All blood cells originate from pluripotent stem cells in bone marrow.

Complete Coverage

Hematopoiesis is the continuous production of blood cells in bone marrow.

Stages

• Stem cell → progenitor cells → mature cells
• Erythropoiesis: RBCs (stimulated by EPO)
• Leukopoiesis: WBCs
• Thrombopoiesis: platelets (stimulated by thrombopoietin)

Sites
Fetal: liver/spleen; adult: flat bones (pelvis, sternum, vertebrae)

Regulation
EPO for RBCs, G-CSF for neutrophils, thrombopoietin for platelets

High-yield fact for exams
Erythropoietin produced by kidneys.

Hemophilia

Quick Fact

Hemophilia A = Factor VIII deficiency.

Complete Coverage

Hemophilia is X-linked recessive bleeding disorder.

Types

• Hemophilia A: Factor VIII deficiency
• Hemophilia B: Factor IX deficiency

Clinical Features
Hemarthrosis, deep muscle hematomas, prolonged bleeding

Management
Factor replacement, desmopressin for mild A

High-yield fact for exams
Joint bleeds lead to arthropathy.

Leukemia

Quick Fact

ALL is most common childhood leukemia.

Complete Coverage

Leukemia is malignant proliferation of immature leukocytes.

Types

• Acute: ALL (children), AML (adults)
• Chronic: CLL (elderly), CML (Philadelphia chromosome)

Signs
Anemia, bleeding, infections, lymphadenopathy

Management
Chemotherapy, targeted therapy (imatinib for CML)

High-yield fact for exams
Philadelphia chromosome in CML.

Sickle Cell Disease

Quick Fact

Sickle cell crisis triggered by dehydration.

Complete Coverage

Pathophysiology
HbS mutation → sickling in low oxygen

Crises
Vaso-occlusive (pain), aplastic, sequestration

Management
Hydration, oxygen, pain control, hydroxyurea

High-yield fact for exams
Hb electrophoresis confirms diagnosis.

Tetralogy of Fallot (TOF)

Quick Fact

TOF causes cyanosis.

Complete Coverage

Four Defects
Pulmonary stenosis, right ventricular hypertrophy, overriding aorta, VSD

Clinical Signs
Cyanosis, clubbing, tet spells

Management
Prostaglandin E1, surgical correction

High-yield fact for exams
Boot-shaped heart on X-ray.

Thalassemia

Quick Fact

Beta thalassemia major requires transfusions.

Complete Coverage

Pathophysiology
Defective globin chain synthesis

Clinical
Severe anemia, hepatosplenomegaly, chipmunk facies

Management
Transfusions + iron chelation

High-yield fact for exams
Crew-cut skull on X-ray.

Frequently Asked Questions (Hematology & Cardio)

Q1: What is the priority nursing intervention for a child with a Sickle Cell Crisis?

Ans: The priority interventions are Hydration (IV fluids) and Pain Management. Hydration helps reduce blood viscosity and prevents further sickling, while pain relief is crucial for the patient's comfort. Oxygen is administered if hypoxia is present.

Q2: What is the immediate nursing action for a "Tet Spell" (Hypercyanotic spell) in a child with TOF?
Ans: The nurse should immediately place the child in a Knee-Chest position (squatting). This position increases systemic vascular resistance, which reduces the shunting of deoxygenated blood and improves oxygenation.

Q3: Which bleeding disorder is caused by the deficiency of Factor VIII?
Ans: Hemophilia A (Classic Hemophilia) is caused by the deficiency of Clotting Factor VIII. It is an X-linked recessive disorder, mostly affecting males.
