MCQS and answers on Rheumatic heart disease

Prevention of Rheumatic heart disease

Prevention focuses on early treatment of streptococcal throat infections.
Primary Prevention
Early treatment of sore throat with antibiotics
Good hygiene
Reduce overcrowding

Secondary Prevention
Long-term antibiotic prophylaxis (e.g., penicillin)
Regular medical follow-up
Guidelines from the World Health Organization emphasize early diagnosis and treatment to prevent valve damage.

Nursing Management
A nurse plays an important role in management by:
Monitoring vital signs
Assessing signs of heart failure
Administering prescribed medications
Educating patients on adherence to antibiotics
Encouraging rest during acute illness

Clinical Pearl
Any child with repeated sore throat should be properly treated to prevent rheumatic fever and Rheumatic Heart Disease.
Early treatment can completely prevent this condition.

RHEUMATIC HEART DISEASE (RHD)
Definition
Rheumatic Heart Disease is a chronic heart condition caused by damage to the heart valves following rheumatic fever.
Rheumatic fever usually occurs after an untreated throat infection caused by Streptococcus bacteria.
The disease mainly affects the heart valves, especially the mitral valve.
Cause
The major cause of Rheumatic Heart Disease is untreated or poorly treated streptococcal throat infection.
Causative organism
Group A beta-hemolytic Streptococcus

Disease process
Streptococcal throat infection
⬇
Immune reaction in the body
⬇
Rheumatic fever
⬇
Inflammation of heart valves
⬇
Permanent valve damage

Rheumatic Heart Disease

Risk Factors
Recurrent untreated sore throat
Overcrowding
Poor access to healthcare
Low socioeconomic conditions
Children aged 5–15 years

Commonly Affected Valves
Mitral valve – most common
Aortic valve
Tricuspid valve (rare)
Damage to these valves can lead to:
Valve stenosis (narrowing)
Valve regurgitation (backflow of blood)

Signs and Symptoms
Patients with Rheumatic Heart Disease may present with:
Shortness of breath
Fatigue
Chest pain
Palpitations
Swollen legs (edema)
Heart murmur on auscultation
In severe cases:
Heart failure
Stroke

Complications
If not properly managed, Rheumatic Heart Disease may lead to:
Heart failure
Valve stenosis or regurgitation
Infective endocarditis
Stroke
Arrhythmias

Normal adult pulse is:
A. 20–40
B. 40–50
C. 60–100
D. 120–140

First stage of labour ends when:
A. Baby is delivered
B. Placenta is delivered
C. Cervix fully dilates
D. Contractions start

Hypertension (high blood pressure) is a chronic medical condition where the blood pressure in the arteries is persistently elevated. Antihypertensive drugs are medications used to lower and control blood pressure to prevent complications such as stroke, heart attack, and kidney damage.

Classification of Antihypertensive Drugs
1. Diuretics
Example: Hydrochlorothiazide, Furosemide
Mechanism: Increase urine output, reducing blood volume and pressure.
Side Effects: Dehydration, electrolyte imbalance (e.g., hypokalemia)
Nursing Considerations: Monitor electrolytes, encourage fluid intake, monitor weight and blood pressure.

2. Beta-Blockers
Example: Atenolol, Metoprolol, Propranolol
Mechanism: Decrease heart rate and cardiac output
Side Effects: Bradycardia, fatigue, cold extremities
Nursing Considerations: Check pulse before administration, monitor for signs of heart failure
3. Calcium Channel Blockers (CCBs)
Example: Amlodipine, Nifedipine, Verapamil
Mechanism: Relax blood vessels by blocking calcium entry into smooth muscles
Side Effects: Swelling (edema), headache, dizziness
Nursing Considerations: Monitor blood pressure, check for swelling, educate about orthostatic hypotension

4. ACE Inhibitors (Angiotensin-Converting Enzyme Inhibitors)
Example: Lisinopril, Enalapril
Mechanism: Inhibit the formation of angiotensin II, reducing vasoconstriction
Side Effects: Dry cough, hyperkalemia, hypotension
Nursing Considerations: Monitor potassium levels, educate patient about dry cough

5. ARBs (Angiotensin II Receptor Blockers)
Example: Losartan, Valsartan
Mechanism: Block angiotensin II receptors, causing vasodilation
Side Effects: Dizziness, increased potassium levels
Nursing Considerations: Alternative to ACE inhibitors if cough develops

6. Alpha Blockers
Example: Prazosin, Doxazosin
Mechanism: Relax blood vessels by blocking alpha-adrenergic receptors
Side Effects: First-dose hypotension, dizziness
Nursing Considerations: Give first dose at bedtime, monitor for falls

7. Centrally Acting Agents
Example: Methyldopa, Clonidine
Mechanism: Reduce sympathetic outflow from the brain
Side Effects: Sedation, dry mouth
Nursing Considerations: Monitor mental alertness, avoid abrupt withdrawal

8. Vasodilators
Example: Hydralazine, Minoxidil
Mechanism: Directly relax arteriolar smooth muscle
Side Effects: Reflex tachycardia, fluid retention
Nursing Considerations: Often used in combination with diuretics

General Nursing Responsibilities in
Antihypertensive Therapy

1. Monitor blood pressure regularly.
2. Educate the patient on lifestyle modification.
3. Monitor for adverse drug reactions.
4. Encourage medication adherence.
5. Teach patients to rise slowly to avoid orthostatic hypotension.
