A nurse is assessing a 6-month-old infant at a well-child visit. Which of the following findings should the nurse expect?
Lateral incisors
Closed posterior fontanel
Sitting steadily without support
Uses thumb and index fingers in a pincer grasp
The Correct Answer is B
The posterior fontanel, located on the back of the head, usually closes by the age of 2-3 months. By 6 months of age, it is expected to be closed.
By 6 months of age, infants typically do not have their lateral incisors. The primary incisors, which are the central incisors in the lower and upper jaw, usually erupt first around 6-10 months of age.
At around 8 months of age, most infants are able to sit steadily without support. They can maintain an upright sitting position and may even start to reach for objects or play in a sitting position.
At 6 months of age, infants are still in the developmental stage of exploring objects and refining their motor skills. They typically use a palmar grasp, where they grasp objects with their entire hand. The pincer grasp, which involves using the thumb and index finger to pick up small objects, usually develops around 9-10 months of age.

Correct Answer is C
Explanation
The appropriate pain rating scale to use for a 2-month-old infant is the FLACC (Face, Legs, Activity, Cry, Consolability) scale. The FLACC scale is commonly used for infants and young children who are unable to self-report their pain. It assesses facial expression, leg movement, activity level, cry, and ability to be consoled. Each category is scored on a scale of 0 to 2, and the total score provides an indication of the infant's pain level.
The PANAD scale and OUCHER scale are more commonly used for older children, while the FACE scale is specific to assessing pain in individuals with cognitive impairments.
Correct Answer is C
Explanation
By 15 months of age, toddlers typically develop the ability to stand and maintain balance without support. This milestone is an important indicator of gross motor development. Not being able to stand upright without support at this age may suggest a delay or impairment in motor skills, and further evaluation may be needed to determine the underlying cause.
The other findings mentioned—difficulty jumping with both feet, inability to build a tower of six to seven cubes, and inability to turn a doorknob—are within the expected range of development for a 15-month-old toddler. While some children may already demonstrate these skills, others may acquire them later in their developmental journey. It is important to consider individual variations in development, but the inability to stand without support should be further assessed.
