Correct Answer: A

Rationale: Validating that the children sent home did develop chickenpox is the most crucial initial step for the nurse. This intervention ensures that the appropriate public health measures are implemented for the containment of chickenpox. Reporting a viral endemic or confirming the number of children with symptoms may be important but are secondary to confirming the diagnosis. Determining the number of people exposed comes after confirming the diagnosis to assess the extent of the outbreak and implement necessary control measures.

Correct Answer: B

Rationale: The correct answer is the 45-year-old father who is overweight and has high cholesterol. He possesses multiple risk factors for diabetes, indicating a need for prioritized evaluation and intervention. The mother's hypertension, the daughter's inactivity, and the son's normal weight and activity level are important factors to consider but do not present as immediate red flags for diabetes risk compared to the father's combination of being overweight and having high cholesterol.

Correct Answer: A

Rationale: The correct answer is early adolescent girls. Scoliosis is most commonly diagnosed during early adolescence, with girls being more affected than boys. Including early adolescent girls in the screening clinic aligns with the age group that is at higher risk for scoliosis. Late adolescent boys (choice B) are less likely to develop scoliosis compared to early adolescent girls. 7-10 year old boys (choice C) are typically younger than the age group where scoliosis is commonly diagnosed. Preschoolers of both genders (choice D) are too young for scoliosis screening as the condition usually manifests during adolescence.

Correct Answer: B

Rationale: The correct answer is to hold the medication and contact the healthcare provider. Bradycardia (pulse rate less than 100 beats/minute) is an early sign of digoxin toxicity. It is essential to withhold digoxin and notify the healthcare provider to prevent potential adverse effects. Administering the medication (Choice A) could exacerbate the toxicity. Doubling the dose (Choice C) is inappropriate and dangerous. Increasing fluid intake (Choice D) is not indicated in this situation and does not address the issue of digoxin toxicity.

Correct Answer: B

Rationale: The correct answer is B: Distributing naloxone kits to first responders. Naloxone is a medication that can rapidly reverse opioid overdose, potentially saving lives. In an opioid crisis scenario, providing naloxone kits to first responders equips them to act swiftly in emergencies. Choice A, providing education on the dangers of opioid use, is important but may not be as immediately life-saving as naloxone distribution. Choice C, offering support groups, is valuable for long-term recovery but may not address the acute crisis of overdoses. Choice D, partnering with local pharmacies to monitor prescriptions, focuses on prevention rather than immediate response to overdoses.
