Rationale: For 13 kg, the maintenance fluid is 1150 mL (1000 mL for first 10 kg + 3*50 mL for the remaining 3 kg). Replacement fluid is 910 mL (0.07 * 13000 mL). Total fluid is 2060 mL, divided by 24 hours is 86 mL/hr.

Correct Answer: D

Rationale: The healthcare professional should refer an infant who is not making babbling sounds by the age of 7 months to a provider for a more extensive evaluation of hearing. Babbling sounds are a developmental milestone that typically occurs by 7 months of age. Delayed or absent babbling can indicate potential hearing issues that warrant further assessment.

Correct Answer: A

Rationale: The correct frame of reference that emphasizes techniques to teach children movement resembling coaching is Motor control/motor learning. This approach focuses on improving movement skills through techniques that are similar to coaching methods. It helps children develop and refine their motor skills in a structured and goal-oriented manner. Rehabilitation, Biomechanical, and Ayres' sensory integration have different emphases and objectives in therapy, making them incorrect choices for this question.

Correct Answer: B

Rationale: Tachycardia is a common early sign of dehydration in infants, especially when presenting with dry mucous membranes and diarrhea. The increased heart rate is the body's compensatory mechanism to maintain cardiac output in response to dehydration. Bradycardia, increased blood pressure, and normal fontanels are not typically associated with early to moderate dehydration in infants.

Correct Answer: A

Rationale: The Peabody Developmental Motor Scale (PDMS-2) is specifically designed to assess the motor development of infants and young children, making it the most appropriate choice for evaluating a 2-month-old infant in a high-risk clinic setting.
