According to Piaget, a 6-month-old infant should be in which developmental stage?
- A. Use of reflexes
- B. Primary circular reactions
- C. Secondary circular reactions
- D. Coordination of secondary schemata
Correct Answer: C
Rationale: Infants are usually in the secondary circular reaction stage from ages 4 to 8 months. This stage is characterized by a continuation of the primary circular reaction for the response that results. Shaking is performed to hear the noise of the rattle, not just for shaking. The use of reflexes stage is primarily during the first month of life. The primary circular reaction stage marks the replacement of reflexes with voluntary acts. The infant is in this stage from ages 1 to 4 months. The fourth sensorimotor stage is coordination of secondary schemata, which occurs at ages 9 to 12 months. This is a transitional stage in which increasing motor skills enable greater exploration of the environment.
What information should be given to the parents of a 12-month-old child regarding appropriate play activities for this age?
- A. Give large push-pull toys for kinetic stimulation.
- B. Place a cradle gym across the crib to help develop fine motor skills.
- C. Provide the child with finger paints to enhance fine motor skills.
- D. Provide a stick horse to develop gross motor coordination.
Correct Answer: A
Rationale: A 12-month-old child is able to pull to a stand and walk holding on or independently. Appropriate toys for this age child include large push-pull toys for kinetic stimulation. A cradle gym should not be placed across the crib. Finger paints are appropriate for older children. A 12-month-old child does not have the stability to use a stick horse.
At a well-child visit, parents ask the nurse how to know if a daycare facility is a good choice for their infant. Which observation should the nurse stress as especially important to consider when making the selection?
- A. Developmentally appropriate toys
- B. Nutritious snacks served to the children
- C. Handwashing by providers after diaper changes
- D. Certified caregivers for each of the age groups at the facility
Correct Answer: C
Rationale: Health practices should be most important. With the need for diaper changes and assistance with feeding, young children are at increased risk when handwashing and other hygienic measures are not consistently used. Developmentally appropriate toys are important, but hygiene and the prevention of disease transmission take precedence. An infant should not have snacks. This is a concern for an older child. Certified caregivers for each age group may be an indicator of a high-quality facility, but parental observation of good hygiene is a better predictor of care.
Which intervention is the most appropriate recommendation for relief of teething pain?
- A. Rub gums with aspirin to relieve inflammation.
- B. Apply hydrogen peroxide to gums to relieve irritation.
- C. Give the infant a frozen teething ring to relieve inflammation.
- D. Have the infant chew on a warm teething ring to encourage tooth eruption.
Correct Answer: C
Rationale: Teething pain is a result of inflammation, and cold is soothing. A frozen teething ring or ice cube wrapped in a washcloth helps relieve the inflammation. Aspirin is contraindicated secondary to the risks of aspiration. Hydrogen peroxide does not have an anti-inflammatory effect. Warmth increases inflammation.
Which characteristic best describes the fine motor skills of an infant at age 5 months?
- A. Neat pincer grasp
- B. Strong grasp reflex
- C. Builds a tower of two cubes
- D. Able to grasp object voluntarily
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.
