the nurse expect to observe?
• A) Sitting without support
• B) Transferring objects hand to hand

transferring objects between hands occurs
around 7 months, and the pincer grasp
develops around 9 months.

"My child only wants to say 'no' and throws
tantrums when I try to help." What is the best
nursing response?
• A) "This is normal for a toddler developing
autonomy."
• B) "You should punish the tantrums
immediately."
• C) "Your child may have oppositional defiant
disorder."
• D) "Ignore the child until the tantrum

doubt. Saying "no" and having tantrums are
normal expressions of developing
independence.
3. A 9-month-old infant is brought for a
checkup. Which finding would require further
evaluation?
• A) Absence of stranger anxiety
• B) Sitting unsupported for 10 seconds
• C) Babbling "mama" and "dada"
• D) Using a raking grasp to pick up a block
Rationale: Stranger anxiety typically appears by
8-9 months of age. Its absence may indicate a
developmental delay and should be evaluated
further. The other options are expected
developmental milestones for a 9-month-old.
