Correct Answer: C

Rationale: Dramatic play involves role-playing, allowing children to act out scenarios and become more comfortable with them. This type of play can help reduce anxiety about upcoming events like surgery. Cooperative play involves working together towards a common goal, associative play involves loosely interacting with others, and onlooker play involves observing others play without actively participating. These types of play are not as directly related to preparing a child for surgery and reducing stress as dramatic play.

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: C

Rationale: By 5 months, an infant's weight should typically double from birth, and length should increase by approximately 50%.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid using any latex product.' In the case of a suspected latex allergy, it is crucial to prevent exposure to latex products to avoid allergic reactions. Choice B is incorrect because there are no truly non-allergenic latex products. Choice C is irrelevant to the situation described in the question, as the child does not have asthma. Choice D is also incorrect because desensitization is not an immediate option for managing a suspected latex allergy.

Correct Answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.
