A school nurse is planning safety education for a group of adolescents. The nurse should give priority to which of the following topics as the leading cause of death for this age group?

The correct answer is Choice A because, a client who has a rigid abdomen with manifestations of shock. This client is showing signs of internal bleeding and hypovolemic shock, which is a medical emergency that requires immediate treatment to prevent further complications or death. Therefore, the priority should be given to this client.

Choice B is wrong because, a client who has a femur fracture with a 2+ pedal pulse, has a stable condition and can wait for treatment. Choice C is wrong because, a client who is ambulatory and exhibits manic behavior, is not a medical emergency and can wait for treatment. Choice D is wrong because, a client who has superficial partial-thickness burn injuries over 5% of his body, can wait for treatment as these injuries are not life-threatening.

Choice A is wrong because, "An adolescent who has scoliosis," Severe scoliosis may require treatment, such as a brace or surgery, but in general, scoliosis is not an acute health emergency. Early detection can help manage the condition effectively, but it is not a priority over more urgent health concerns.

Choice B is wrong because, "An adolescent who has psoriasis," is not the correct answer as it is not an urgent health issue that requires immediate attention.

Choice C is correctbecause, "A child who has nits," Nits are the eggs of lice, which are tiny parasitic insects that infest the scalp, causing itching and discomfort. While head lice infestation can be a nuisance, it is generally not dangerous. However, it is highly contagious, especially in a school setting, and can spread rapidly among children.

Choice D is wrong because, "A child who has a BMI of 18," is also not the correct answer as while it is important to address, it is not an urgent health issue that requires immediate attention.
