Autism is a complex developmental disorder. The diagnostic criteria for autism include delayed or abnormal developmental function. Which of the following behaviors would be a concerning sign in 10-month-old infant?
Pulling themselves up to standing position
Inability to maintain eye contact
Parallel play
Growth below the 5th percentile
The Correct Answer is B
A. Pulling themselves up to a standing position is a motor milestone that is typically achieved around 9- 12 months of age. While delays in motor milestones can sometimes be concerning, they are not specific signs of autism at this age.
B. Autism is primarily characterized by social communication and interaction difficulties, as well as restricted and repetitive behaviors. At 10 months old, infants typically start to engage in social interactions, including making eye contact with caregivers
C. Parallel play is where children play alongside each other without interacting directly, is a social milestone that typically develops around 2-3 years of age.
D. Growth below the 5th percentile may indicate poor growth or failure to thrive, but it is not a specific behavioral sign of autism.

Correct Answer is B
Explanation
Pyloric stenosis is characterized by the narrowing of the pylorus, the opening between the stomach and the small intestine. This narrowing obstructs the passage of food from the stomach to the small intestine, leading to symptoms such as projectile vomiting.
A. Red currant jelly stools are typically associated with intussusception - telescoping of one segment of the intestine into another.
C. Distended neck veins are not typically associated with pyloric stenosis. Distended neck veins may occur in conditions such as heart failure or superior vena cava obstruction.
D. Ridged abdomen: Pyloric stenosis may lead to a palpable olive-shaped mass in the right upper quadrant of the abdomen, but a ridged abdomen is not a typical finding.
Correct Answer is C
Explanation
A. Infants at 7 months of age begin to develop a pincer grasp, which involves using the thumb and index finger to pick up small objects. This is considered a normal developmental milestone.
B. Development of food preferences is a normal aspect of infant development as they explore different tastes and textures and, therefore, no need for further evaluation.
C. Infants at 7 months of age exhibit more advanced language development compared to earlier months. Babbling one-syllable sounds is a milestone expected by this age, and a lack of babbling may indicate a delay in language development warranting further evaluation by a healthcare provider.
D. Stranger anxiety typically emerges around 6 to 9 months of age as infants become more aware of unfamiliar people and may exhibit fear or discomfort in their presence. This is considered a normal developmental stage
