The directive 'outline' for part (a)(iv) and the enumeration demands in parts (b) and (c) require structured, hierarchical presentation. Allocate approximately 40% of time/space to part (a) given its 20 marks with clinical reasoning depth, 40% to part (b) for precise WHO criteria and ten-step protocol, and 20% to part (c) for concise radiological differentials. Begin each sub-part with clear headings, use bullet points for criteria and steps, and conclude with brief clinical relevance statements.
- Part (a): Diagnosis of bronchial asthma with seasonal pattern; confirmation via spirometry with reversibility (FEV1 improvement ≥12% and ≥200ml post-bronchodilator), peak expiratory flow variability; clinical features including episodic dyspnea, wheeze, chest tightness, nocturnal symptoms, triggers; stepwise GINA management from Step 1 (SABA PRN) to Step 5 (high-dose ICS-LABA + add-ons)
- Part (b)(i): WHO criteria for SAM—weight-for-height/length Z-score <-3 SD OR mid-upper arm circumference (MUAC) <11.5 cm OR bilateral pitting edema (nutritional edema); age 6-59 months
- Part (b)(ii): Facility-based admission criteria—complicated SAM (edema++, severe illness, anorexia, failed outpatient care, HIV/infant <6 months/other danger signs) per WHO/Indian Academy of Pediatrics guidelines
- Part (b)(iii): Ten steps—treat/prevent hypoglycemia, hypothermia, dehydration, electrolyte imbalance, infection, micronutrient deficiencies; initiate cautious feeding, achieve catch-up growth, provide sensory stimulation, prepare for follow-up (WHO protocol)
- Part (c): X-ray in acute abdomen—erect chest for free air under diaphragm (perforation), supine abdomen for dilated bowel loops/valvulae conniventes/coffee bean sign (volvulus), air-fluid levels on erect abdomen (obstruction), sentinel loop (pancreatitis), psoas shadow obliteration (retroperitoneal pathology), calcifications (renal/ureteric stones, chronic pancreatitis), loss of flank stripe (ascites)

Dimension	Weight	Max marks	Excellent	Average	Poor
Concept correctness	20%	10	Accurately identifies asthma with correct reversibility criteria (FEV1 ≥12% and ≥200ml); precisely states WHO SAM criteria with correct MUAC cutoff (<11.5cm) and Z-score threshold; correctly describes radiological signs (Rigler's sign, coffee bean, sentinel loop) with anatomical basis	Identifies asthma but reversibility criteria incomplete or incorrect; SAM criteria partially correct with minor numerical errors; lists X-ray findings without anatomical correlation or misses key signs	Misdiagnoses as COPD/heart failure; confuses SAM with moderate acute malnutrition; fundamental errors in X-ray interpretation (e.g., describes CT findings, confuses perforation with obstruction signs)
Clinical correlation	20%	10	Links seasonal pattern to allergen exposure in asthma; correlates edema in SAM with hypoalbuminemia and infection risk; connects free air under diaphragm to anterior perforation in peptic ulcer; mentions Indian context (high pollen zones, NFHS-5 malnutrition data, tropical enteropathy)	Mentions clinical features without pathophysiological linkage; generic statements about SAM complications; lists X-ray findings without clinical correlation to specific surgical emergencies	No clinical reasoning provided; purely theoretical answer without patient context; fails to distinguish between adult asthma presentation and pediatric SAM management needs
Diagram / pathway	20%	10	Draws GINA stepwise asthma management flowchart with Step 1-5 clearly demarcated; sketches WHO ten-step SAM management algorithm with stabilization and rehabilitation phases; illustrates X-ray findings (dilated loops, air-fluid levels, free air) with labeled diagrams	Describes pathways in text without diagrams; attempts flowchart but misses steps (e.g., omits Step 5 biologics or SAM step 10); mentions X-ray positions (erect/supine) without visual representation	No diagrams or structured pathways; disorganized presentation; confuses asthma stepwise therapy with COPD GOLD classification or SAM steps with IMNCI protocol
Differential / staging	20%	10	Provides differentials for asthma (COPD, cardiac asthma, vocal cord dysfunction, ABPA); stages asthma severity (intermittent/persistent-mild/moderate/severe) and control levels; differentiates SAM edema from kwashiorkor/marasmus; classifies acute abdomen causes (surgical vs medical) with X-ray discriminators	Lists 1-2 differentials without distinguishing features; mentions severity but not staging criteria; acknowledges kwashiorkor but doesn't differentiate from marasmus; limited acute abdomen differentials	No differentials provided; confuses asthma with COPD without distinction; fails to recognize that edema in SAM indicates kwashiorkor variant; no attempt to classify acute abdomen etiologies
Management / public-health angle	20%	10	Comprehensive GINA 2023 stepwise approach with ICS-formoterol as reliever option; detailed WHO ten-step SAM protocol with transition criteria; mentions Indian public health programs (Rashtriya Bal Swasthya Karyakram, ICDS); includes asthma action plan and SAM discharge criteria; emphasizes radiation safety in acute abdomen imaging	Basic stepwise management without recent updates; lists SAM steps 1-10 mechanically; generic public health mention without program specifics; omits transition from facility to community-based management	Outdated asthma management (no LABA safety mention); incorrect SAM steps (e.g., aggressive feeding early); no public health context; suggests unnecessary repeated X-rays without ALARA principle
