A nurse is reinforcing education to the caregiver of a 2-year-old toddler diagnosed with lead poisoning. Which of the following statements should the nurse make?

"You should give the child calcium supplements to treat the lead poisoning."

"Prevent the child from playing in areas where lead-based paint may have been used."

"Make sure to cook and store food in lead crystal containers to avoid contamination."

"Let the child play outside often to dilute the concentration of lead in their body."

Answer and Explanation

The Correct Answer is B

A. "You should give the child calcium supplements to treat the lead poisoning." While calcium, iron, and vitamin C can help reduce lead absorption, they do not directly treat lead poisoning. Chelation therapy is the primary treatment for high lead levels.

B. "Prevent the child from playing in areas where lead-based paint may have been used." Lead-based paint (commonly found in homes built before 1978) is a major source of lead poisoning in children. Preventing exposure by avoiding contaminated areas and addressing lead hazards is crucial in managing and preventing further poisoning.

C. "Make sure to cook and store food in lead crystal containers to avoid contamination." Lead crystal containers can leach lead into food and beverages, increasing exposure. Glass, stainless steel, or BPA-free plastic containers should be used instead.

D. "Let the child play outside often to dilute the concentration of lead in their body." Outdoor play does not lower lead levels. The body requires proper nutrition, reduced exposure, and medical treatment (such as chelation therapy) to eliminate lead safely.

Correct Answer is B

Explanation

A. Leukocytes. Leukocytes (white blood cells) are involved in the immune response and are not the primary cells affected in testicular cancer. Cancers of leukocytes include leukemia and lymphoma, not testicular cancer.

B. Germ cells. This is correct. Testicular cancer most commonly arises from germ cells, which are the cells responsible for producing sperm. Germ cell tumors (GCTs) account for over 90% of testicular cancers, including seminomas and non-seminomas.

C. Epithelial cells. Epithelial cells line various tissues and organs, but they are not the primary source of testicular cancer. Epithelial cell cancers, like carcinomas, more commonly affect the skin, lungs, and digestive tract.

D. Lymphocytes. Lymphocytes are a type of white blood cell involved in the immune system. Testicular lymphoma can occur but is rare compared to germ cell tumors, which are the most frequent type of testicular cancer in adolescents and young adults.

A. “Cognitive abilities in children with Down syndrome cannot be improved, so focusing on physical health is the only priority." B. “Infants who have Down syndrome typically have significantly higher IQ scores compared to typically developing infants." C. “Early intervention programs can mitigate cognitive impairments in infants who have Down syndrome." D. “Cognitive abilities of infants who have Down syndrome are typically within the average range during the first year of life."

Correct Answer is C

Explanation

A. "Cognitive abilities in children with Down syndrome cannot be improved, so focusing on physical health is the only priority." While children with Down syndrome do experience cognitive impairments, early intervention programs such as speech, occupational, and physical therapy can enhance cognitive, motor, and social development, improving their overall functioning.

B. "Infants who have Down syndrome typically have significantly higher IQ scores compared to typically developing infants." Children with Down syndrome generally have mild to moderate intellectual disability, and their IQ scores tend to be lower than typically developing peers, not higher.

C. "Early intervention programs can mitigate cognitive impairments in infants who have Down syndrome." This is correct. Early stimulation, structured learning environments, and specialized therapies can help optimize the child's cognitive potential and improve adaptive skills.

D. "Cognitive abilities of infants who have Down syndrome are typically within the average range during the first year of life." Although some developmental milestones may appear similar in early infancy, delays in cognitive and motor development often become noticeable within the first year, distinguishing children with Down syndrome from their typically developing peers.
