Question

68 multiple choice 1 point the health care provider explains to the adolescent that hearing can be damaged at or above 60db 90db 40db 130db 69 true or false 1 point astigmatism is eye misalignment (sometimes called cross - eyed) true false 70 multiple choice 1 point the main bone of the thigh is the tibia humerus

Explanation:

• For question 68: Prolonged exposure to sounds at or above 90dB can cause hearing damage. 130dB is an extremely loud level that can cause immediate damage. 60dB is a relatively normal - level sound like normal conversation, and 40dB is quiet like a library.
• For question 69: Astigmatism is a refractive error where the eye is irregularly shaped, not eye misalignment (cross - eyed is strabismus).
• For question 70: The tibia is the shin bone, and the humerus is the upper arm bone. The main bone of the thigh is the femur, but among the given options, neither is correct, but the knowledge point is about bone identification.

Answer:

1. B. 90dB
2. False
3. None of the above (as neither tibia nor humerus is the main thigh bone; the main thigh bone is the femur)
