You're assessing a 4-month-old infant. Which finding below is a normal milestone that should be reached by this infant at this age?

Pincer grasp

Rolls from tummy to back

Walks with support

Rolls from back to tummy

Answer and Explanation

The Correct Answer is B

A. Pincer grasp: The pincer grasp, which involves using the thumb and forefinger to pick up small objects, typically develops around 8 to 12 months of age, not at 4 months.

B. Rolls from tummy to back: At 4 months, many infants start to develop the ability to roll from their tummy to their back. This is a typical milestone for this age and reflects developing motor skills.

C. Walks with support: Walking with support usually begins around 9 to 12 months of age, much later than 4 months.

D. Rolls from back to tummy: Rolling from back to tummy typically occurs a bit later, often around 5 to 6 months. At 4 months, rolling from tummy to back is the more expected milestone.

Correct Answer is A

Explanation

A. Ask the client to read a Snellen chart: Cranial nerve II (Optic nerve) is responsible for vision. Assessing the client's ability to read a Snellen chart tests visual acuity, which is a function of cranial nerve II.

B. Listen to the client's speech: This assesses cranial nerves V (Trigeminal) and VII (Facial), which are involved in speech and facial sensation.

C. Ask the client to clench his teeth: This assesses cranial nerve V (Trigeminal), which controls jaw movement and sensation.

D. Ask the client to identify scented aromas: This assesses cranial nerve I (Olfactory), which is responsible for the sense of smell.

A. 20 B. 32 C. 24 D. 16

Correct Answer is C

Explanation

A. 20 lbs: This is a plausible estimate. By 12 months, an infant's birth weight typically triples. Therefore, an 8 lb birth weight would approximately translate to 24 lbs at 12 months.

B. 32 lbs: This estimate is too high. If an infant's birth weight triples by 12 months, an 8 lb birth weight would not be expected to reach 32 lbs.

C. 24 lbs: An infant's weight usually triples by their first birthday. Therefore, an infant born weighing 8 lbs would be expected to weigh about 24 lbs at 12 months.

D. 16 lbs: This is an underestimate. An 8 lb infant would double their birth weight by about 4 to 6 months, and by 12 months, they would typically have tripled their birth weight to around 24 lbs.
