Duke's major and minor criteria used for which disease?

Appeared in: PGIMER NO - 2020

Explanation

The Modified Duke Criteria are the established standard for diagnosing Infective Endocarditis (IE).
The criteria are divided into 'major' and 'minor' categories to increase diagnostic accuracy.
Major criteria include definitive findings like positive blood cultures for typical IE organisms and echocardiographic evidence of endocardial involvement (e.g., vegetation).
Minor criteria are less specific but suggestive findings, such as fever, a predisposing heart condition, or vascular phenomena like Janeway lesions.

Option A: Rheumatic heart disease is diagnosed using the Jones Criteria, not the Duke Criteria.
Option C: Pleurisy is an inflammation of the lung's lining, diagnosed by clinical signs like pleuritic chest pain and friction rub, not by a specific set of named criteria like Duke's.
Option D: Cardiac tamponade is a clinical diagnosis, classically associated with Beck's Triad (hypotension, JVD, muffled heart sounds).

Clinical Relevance

Nursing practice connection: Knowing Diagnostic criteria for infective endocarditis helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a crucial role in diagnosing IE by meticulously collecting patient history (e.g., IV drug use, recent dental procedures), monitoring for fever, and drawing blood cultures correctly before starting antibiotics.
Long-term IV antibiotic therapy (4-6 weeks) is the cornerstone of treatment. Nurses manage the central line, administer medications on schedule, and monitor for adverse drug reactions.
A key nursing responsibility is to monitor for embolic events, a life-threatening complication of IE. This includes performing regular neurological checks for stroke, assessing for sudden flank pain (renal embolus), or acute limb pain (peripheral embolus).

How to Approach the Question

This is a factual recall question that tests your knowledge of specific diagnostic criteria.
First, identify the key term in the question: 'Duke's major and minor criteria'.
Next, mentally retrieve the disease associated with this specific set of criteria.
Evaluate the options provided. 'Infective endocarditis' is the direct match for Duke's criteria.
To confirm, quickly recall the criteria for the other options. Rheumatic heart disease uses Jones Criteria, and Cardiac Tamponade uses Beck's Triad, confirming they are incorrect.
