A nurse is contributing to the development of an in-service training about child maltreatment for a group of pediatric nurses. Which of the following findings should the nurse identify as a risk factor for child maltreatment?

A. Smoking in bed: Smoking in bed is a major fire hazard and one of the leading causes of residential fires. Falling asleep with a lit cigarette can easily ignite bedding, mattresses, or upholstered furniture, leading to fast-spreading, deadly fires. This behavior significantly increases the risk of injury or death from residential fires.

B. Leaving the stove on: Leaving the stove unattended can also cause kitchen fires, but cooking-related incidents typically lead to localized fires rather than being the top cause of overall residential fires. Proper supervision while cooking is important, but smoking in bed remains a more dangerous, widespread cause of fatal home fires.

C. Lack of smoke detectors: Lack of smoke detectors does not cause fires but delays detection, increasing the risk of injury or death once a fire has already started. While smoke detectors are crucial for early warning and safety, they are not an ignition source that directly leads to the start of residential fires.

D. Placing a space heater 5ft from bed: Placing a space heater 5 feet away from a bed is generally considered safe, as heaters need clearance but are unlikely to cause fires at that distance. Improper use of space heaters can be hazardous, but when correctly placed, they are not the primary cause of residential fires compared to smoking in bed.

A: Image A shows the ankle area, which is an example of a hinge joint, not a ball and socket joint. Hinge joints allow movement in one plane, such as flexion and extension, similar to the motion of a door hinge. The ankle allows primarily up-and-down movement but does not rotate in multiple directions like a ball and socket joint would.

B: Image B shows the hip area, which represents a ball and socket joint. In a ball and socket joint, the round head of one bone fits into the cup-like socket of another bone, allowing movement in multiple directions. The hip and the shoulder are classic examples of ball and socket joints, permitting rotation, flexion, extension, abduction, and adduction.
