Abuse and violence contribute significantly to mental illness in children

A. Increased urinary output: Polyuria is not a characteristic sign of lead poisoning. Lead primarily affects the hematologic, neurologic, and gastrointestinal systems rather than directly influencing renal water regulation, unless nephropathy develops in chronic exposure.

B. Anorexia: Loss of appetite is a common manifestation of acute lead poisoning due to the toxic effects of lead on the gastrointestinal tract and central nervous system. The child may also experience abdominal pain, irritability, and constipation in addition to decreased appetite.

C. Jaundice: Jaundice is not typically associated with lead poisoning. Although lead interferes with heme synthesis, it does not usually cause bilirubin accumulation or liver dysfunction that would result in jaundice.

D. Diarrhea: Gastrointestinal upset can occur, but diarrhea is not as common as constipation in lead toxicity. Lead decreases peristalsis and causes smooth muscle spasm in the intestines, leading more often to constipation than to diarrhea.

A. Engaging in daily weight-bearing exercise: Weight-bearing activities such as walking, dancing, or light resistance training stimulate bone formation and slow mineral loss, helping maintain bone density and strength. Regular exercise also improves balance, reducing the risk of fractures from falls.

B. Limiting intake of cholesterol and saturated fats: While beneficial for cardiovascular health, reducing dietary fat does not directly influence bone density or the prevention of osteoporosis. The focus for osteoporosis prevention should be on calcium and vitamin D intake and physical activity.

C. Decreasing vitamin D intake: Vitamin D is essential for calcium absorption and bone mineralization. Decreasing intake would weaken bone health and increase the risk of osteoporosis and fractures, particularly in postmenopausal women.

D. Drinking at least 1 glass of wine per day: Alcohol consumption should be limited because excessive intake interferes with calcium absorption and bone remodeling. Even moderate daily drinking may negatively affect bone density in some individuals.
