Child criteria include A/E a) Nutritional status b) S.Bilirubin c) S. Creatinine d) Acid phosphate

**Core Concept**
Child's criteria, also known as Child-Pugh score, is a system used to assess the prognosis of patients with liver cirrhosis. It takes into account several clinical and laboratory parameters to predict the severity of liver disease and the risk of complications.

**Why the Correct Answer is Right**
The correct answer includes nutritional status, serum bilirubin, serum creatinine, and albumin levels, which are all essential components of the Child-Pugh score. The score is calculated by assigning points for each parameter, with a higher score indicating more severe liver disease. The correct answer excludes serum alkaline phosphatase (acid phosphate) because it is not a component of the Child-Pugh score.

**Why Each Wrong Option is Incorrect**
**Option A:** Nutritional status is a crucial component of the Child-Pugh score, as malnutrition is common in patients with liver cirrhosis.

**Option B:** Serum bilirubin is a key parameter in the Child-Pugh score, reflecting the liver's ability to clear bilirubin from the blood.

**Option C:** Serum creatinine is included in the Child-Pugh score to assess renal function, which is often impaired in patients with liver cirrhosis.

**Option D:** Acid phosphate, or serum alkaline phosphatase, is not a component of the Child-Pugh score, making it the correct answer for the "A/E" (all except) question.

**Clinical Pearl / High-Yield Fact**
The Child-Pugh score is a subjective scoring system, and its accuracy can be influenced by the clinician's interpretation. However, it remains a widely used tool for assessing liver function and guiding treatment decisions.

**Correct Answer:** D. Acid phosphate
