### The Best indicator for nutritional status for a child is

• A.

Chest circumference

• B.

Rate of increase of height and weight

• C.

Mid arm circumference

• D.

B. Rate of increase of height and weight
Explanation
Rate of increase of height and weight is the best indicator for nutritional status in a child because it reflects the child's overall growth and development. A steady and appropriate rate of increase in height and weight indicates that the child is receiving adequate nutrition and is developing normally. On the other hand, a slow or stagnant rate of growth may suggest malnutrition or underlying health issues. Therefore, monitoring the rate of increase of height and weight is crucial in assessing a child's nutritional status.

### 6 yr old child has the IQ of only 50. Which of the following can the child do?

• A.

• B.

Ride a bicycle

• C.

Copy a triangle

• D.

Identify colours

D. Identify colours
Explanation
A child with an IQ of 50 is considered to have a moderate intellectual disability. This means that their cognitive abilities are significantly below average. While they may struggle with tasks that require higher cognitive skills such as reading a sentence or copying a triangle, they should still be able to identify colors as it is a simpler task that does not require complex cognitive processing. Therefore, the child should be able to identify colors.

### A newborn baby had profuse bleeding from umbilical stump after birth. Probable diagnosis is....

• A.

Factor XIII deficiency

• B.

Glanzmann thrombosthenia

• C.

Factor XII deficiency

• D.

VWF deficiency

A. Factor XIII deficiency
Explanation
Factor XIII deficiency is a rare inherited bleeding disorder characterized by a deficiency or dysfunction of Factor XIII, a clotting factor involved in stabilizing blood clots. This deficiency results in impaired clot formation and increased bleeding. The profuse bleeding from the umbilical stump in the newborn baby suggests a potential diagnosis of Factor XIII deficiency, as this condition can present with bleeding from the umbilical cord stump shortly after birth.

### A newborn  with congestive heart failure, on examination has bulging anterior fontanellae with a bruit on ausculation.Transfontanella usg shows a hypoechoic midline mass with dilated lateral ventricles. Most likely diagnosis is...

• A.

Medulloblastoma

• B.

Encephalocele

• C.

Vein of Galen malformation

• D.

Arachnoid cyst

C. Vein of Galen malformation
Explanation
The most likely diagnosis for a newborn with congestive heart failure, bulging anterior fontanelle, bruit on auscultation, and findings of a hypoechoic midline mass with dilated lateral ventricles on transfontanellar ultrasound is a Vein of Galen malformation. Vein of Galen malformation is a rare congenital abnormality where there is an abnormal connection between the arteries and veins in the brain, leading to high-flow arteriovenous shunting. This can result in heart failure and hydrocephalus, which explains the clinical findings in this newborn.

### Common to both acute and chronic malnutrition is ....

• A.

Weight for age

• B.

Height for age

• C.

Weight for height

• D.

None of the above

A. Weight for age
Explanation
Weight for age is a common indicator used to assess both acute and chronic malnutrition. It measures a child's weight in relation to their age and helps to identify if a child is underweight or malnourished. This indicator is useful in identifying both acute malnutrition, which is characterized by a rapid decline in weight, as well as chronic malnutrition, which is characterized by long-term inadequate nutrition leading to stunted growth. Therefore, weight for age is a relevant and important measure in assessing malnutrition in children.
