Question 1 of 5
Which characteristic best describes the fine motor skills of an infant at age 5 months?
Correct Answer: D
Rationale: At age 5 months, the infant should be able to voluntarily grasp an object. The grasp reflex is present in the first 2 to 3 months of life. Gradually, the reflex becomes voluntary. The neat pincer grasp is not achieved until age 11 months. At age 12 months, an infant will attempt to build a tower of two cubes but will most likely be unsuccessful.
Question 2 of 5
The nurse is checking reflexes on a 7-month-old infant. When the infant is suspended in a horizontal prone position, the head is raised and the legs and spine are extended. Which reflex is this?
Correct Answer: A
Rationale: When the infant is suspended in a horizontal prone position, the head is raised and the legs and spine are extended; this describes the Landau reflex. It appears at 6 to 8 months and persists until 12 to 24 months. The parachute reflex occurs when the infant is suspended in a horizontal prone position and suddenly thrust downward; the infant extends the hands and fingers forward as if to protect against falling. This appears at age 7 to 9 months and lasts indefinitely. Body righting occurs when turning the hips and shoulders to one side causes all other body parts to follow. It appears at 6 months of age and persists until 24 to 36 months. The labyrinth-righting reflex appears at 2 months and is strongest at 10 months. This reflex involves holding infants in the prone or supine position. They are able to raise their heads.
Question 3 of 5
In terms of gross motor development, what should the nurse expect an infant age 5 months to do?
Correct Answer: C
Rationale: Rolling from the abdomen to the back is developmentally appropriate for a 5-month-old infant. The ability to roll from the back to the abdomen is developmentally appropriate for an infant at age 6 months. Sitting erect without support is a developmental milestone usually achieved by 8 months. A 10-month-old infant can usually move from a prone to a sitting position.
Question 4 of 5
At which age can most infants sit steadily unsupported?
Correct Answer: C
Rationale: Sitting erect without support is a developmental milestone usually achieved by 8 months. At age 4 months, an infant can sit with support. At age 6 months, the infant will maintain a sitting position if propped. By 10 months, the infant can maneuver from a prone to a sitting position.
Question 5 of 5
By which age should the nurse expect that an infant will be able to pull to a standing position?
Correct Answer: C
Rationale: Most infants can pull themselves to a standing position at age 9 months. Infants who are not able to pull themselves to standing by age 11 to 12 months should be further evaluated for developmental dysplasia of the hip. At 6 months, infants have just obtained coordination of arms and legs. By age 8 months, infants can bear full weight on their legs.
