A nurse is collecting data from a 6-week-old infant. Which of the following findings should the nurse expect?
Absence of Babinski reflex
Absence of Moro reflex
Closure of the posterior fontanel
Closure of the anterior fontanel
The Correct Answer is C
A. Absence of Babinski reflex: The Babinski reflex (a fanning of the toes when the sole of the foot is stroked) is normal in infants and should be present until around 12 months of age. Its absence at 6 weeks would be atypical.
B. Absence of Moro reflex: The Moro reflex (a startle response) is typically present in newborns and may begin to disappear by 3-6 months of age. Its absence at 6 weeks would be concerning and could indicate neurological issues.
C. Closure of the posterior fontanel: The posterior fontanel typically closes by 6-8 weeks of age. This is a normal finding for a 6-week-old infant.
D. Closure of the anterior fontanel: The anterior fontanel typically closes between 12 and 18 months of age, not by 6 weeks. Therefore, closure of the anterior fontanel at 6 weeks would be unusual.

Correct Answer is D
Explanation
A. "You should position the car seat at a 30-degree angle." The correct angle for rear-facing car seats is 45 degrees. A 30-degree angle may cause the infant’s head to fall forward, increasing the risk of airway obstruction.
B. "You should place a folded blanket to pad the back of the infant's head." Extra padding behind or around the infant's head is not recommended as it may interfere with the seat’s effectiveness and safety in a crash.
C. "You should use a car seat with a four-point harness." The recommended harness system is a five-point harness, which provides more secure restraint at the shoulders, hips, and between the legs.
D. "You should place the retainer clip at the level of the infant's armpits." Correct placement of the retainer (chest) clip is at armpit level. This ensures that the harness straps stay positioned over the shoulders, reducing the risk of injury during a crash.
Correct Answer is C
Explanation
A. Hopscotch: Hopscotch typically requires the ability to hop on one foot and follow a structured set of rules, which may be too advanced for a 2-year-old. Toddlers are still developing coordination and motor skills, so activities like hopscotch are not age-appropriate.
B. Beginner sports: While toddlers can start developing coordination, organized sports (even beginner ones) usually require more advanced skills like following directions and teamwork, which may not be suitable for a 2-year-old.
C. Finger paints: Finger painting is an ideal activity for a 2-year-old. It encourages creativity, helps with fine motor skills, and is enjoyable for toddlers as they explore textures and colors. It is a developmentally appropriate form of play.
D. 30-piece puzzle: A 30-piece puzzle may be too complex for a 2-year-old. Toddlers typically enjoy simpler puzzles with larger pieces, which are easier for their developing fine motor skills and cognitive abilities. A simpler puzzle would be more appropriate.
