Q11Which child requires the most urgent blood lead screening based on the risk factors presented?
✓ Correct answer: D. Toddler with a sibling treated for lead poisoning
A sibling with elevated BLL indicates a shared environmental hazard, requiring immediate screening. Housing age is a risk but less specific than a confirmed household case.
Q12A parent asks for immediate steps to reduce lead exposure in the home pending inspection. Which advice is most appropriate?
✓ Correct answer: A. Wet mop all floors and window sills every week
Wet mopping traps lead dust, while dry sweeping or vacuuming aerosolizes it. Paint removal requires professional containment to prevent dangerous dust dispersion.
Q13Which clinical scenario warrants escalation to public health for home inspection and case management?
✓ Correct answer: C. Venous blood lead levels rise despite mitigation
Rising venous levels despite education indicate ongoing exposure requiring investigation. Capillary screens need venous confirmation. Housing age alone does not trigger management.
Q14A nurse provides nutritional counseling for a child with a blood lead level of 5 µg/dL. Which dietary change should be recommended?
✓ Correct answer: E. Regular intake of yogurt and lean red meat products
Calcium and iron compete with lead for absorption, reducing uptake. Vitamin C aids iron absorption but is insufficient alone. High fat intake can increase lead absorption.
Q15A 2-year-old has a confirmed blood lead level of 15 µg/dL and significant language delay. Which referral combination is indicated?
✓ Correct answer: B. Early Intervention and health department
Levels ≥5 µg/dL require environmental case management. Developmental delays necessitate Early Intervention. Inpatient care is for severe toxicity; waiting delays support.
Q16A parent is unsure of the year their home was built during a risk assessment. What is the correct nursing action?
✓ Correct answer: D. Perform blood lead screening
Unknown housing age defaults to high risk, requiring screening. Assuming low risk or relying solely on pica presence ignores potential environmental hazards.
Q17A refugee family with a 3-year-old child arrives for a first visit. The child lives in post-1978 housing. What is the appropriate action?
✓ Correct answer: A. Screen for lead exposure
Refugee/immigrant children are high-risk regardless of current housing due to potential prior exposures or non-housing sources (cookware, traditional remedies). Screening is mandatory upon entry to care.
Q18A child has an initial venous blood lead level of 22 µg/dL. According to CDC guidelines, when should the nurse schedule repeat testing?
✓ Correct answer: C. Schedule within one month
BLLs of 20-44 µg/dL require confirmation within one month to track trajectory. Three months is too long; chelation is reserved for levels ≥45 µg/dL.
Q19A child in a new home has an elevated blood lead level. Which question helps identify the likely source?
✓ Correct answer: E. Do you use imported spices or cosmetics?
Consider non-housing sources like imported goods, occupations, or hobbies. Post-1978 schools and standard plastic toys are unlikely sources; pets are not primary vectors.
Q20A family relies on a wood-burning stove for heat, and their child has persistent asthma. Financial constraints prevent replacing the heating system. Which recommendation is most appropriate to mitigate indoor air quality risks?
✓ Correct answer: B. Use a portable HEPA filter in the child's sleeping area
HEPA filters reduce indoor particulates. Sealing rooms increases pollution concentration. Other options are cost-prohibitive or ineffective for this specific scenario.
