Correct Answer: C

Rationale: For school-aged children, pedestrian, motor vehicle, and bike safety are critical areas to focus on as accidents involving these are common in this age group. Education about fire safety and toxic substances is also important, but the priority is on preventing accidents in everyday activities. Therefore, choices A, B, and D are not the most relevant for addressing the goal of decreasing injuries and accidents in this age group.

Correct Answer: B

Rationale: The correct answer is B: 'In the treatment room.' Performing painful procedures in the treatment room helps the child associate their own room with safety and comfort, not pain. Choice A is incorrect because performing the dressing change in the patient's room may create a negative association with their safe space. Choice C is incorrect as it is important to ensure proper wound care and pain management before discharge. Choice D is incorrect as the playroom may not be equipped for a sterile dressing change.

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.

Correct Answer: A

Rationale: To administer 2 mg of Morphine Sulfate when the concentration is 10 mg/mL, the nurse should administer 0.2 mL (2 mg / 10 mg/mL = 0.2 mL). Choice B, 0.5 mL, is incorrect because it is the result of dividing 2 mg by 4 mg/mL instead of 10 mg/mL. Choice C, 1 mL, is incorrect as it would be the result of dividing 2 mg by 2 mg/mL. Choice D, 2 mL, is incorrect as it would be the result of dividing 2 mg by 1 mg/mL.

Correct Answer: B

Rationale: Administering antibiotics on schedule is crucial in treating a UTI effectively and preventing complications. Antibiotics help to eliminate the infection-causing bacteria from the urinary tract. While maintaining adequate nutrition and hydration are important aspects of care, the priority in a UTI is to target the infection with antibiotics. Preventing enuresis (bedwetting) is not directly related to the treatment of the infection. Fluid restriction is not recommended in the management of a UTI; in fact, encouraging adequate fluid intake helps flush out bacteria from the urinary tract.
