Correct Answer: D

Rationale: The priority action for the nurse when the apnea monitor alarm sounds on a neonate is to assess the infant for color and the presence of respirations. This initial assessment helps determine the infant's respiratory status and the need for immediate intervention. Providing tactile stimulation or administering oxygen should only be done after assessing the infant's respiratory status. Investigating possible causes of a false alarm comes after ensuring the infant's well-being through the initial assessment.

Correct Answer: B

Rationale: At 2 months, infants typically react to loud noises with the Moro reflex, a startle response that is normal at this stage of development.

Correct Answer: C

Rationale: The correct answer is C. According to Erikson, the primary task of a preschool-aged child is to explore and assert control over their environment. This behavior is demonstrated by the child opening drawers, pulling out supplies, and examining them, showcasing curiosity and exploration. Choices A, B, and D do not align with the primary developmental task of a preschool-age child according to Erikson. Reading a book and singing a song are more passive activities, while roughhousing with the parent does not directly relate to exploration and asserting control over the environment.

Correct Answer: B

Rationale: At 2 months, infants are most stimulated by visual and auditory activities, such as a music box or soft mobiles. These activities help in sensory development and are appropriate for this age.

Correct Answer: A

Rationale: Playing peek-a-boo is an ideal play activity for a 7-month-old as it encourages visual tracking and social interaction, which are key developmental milestones at this age.
