A nurse participating in lead screening at a community center.
The nurse should instruct parents to bring their children back for rescreening in a year for which of the following laboratory values?
10 mcg/dL
18 mcg/dL
4 mcg/dL
44 mcg/dL.
The Correct Answer is C
The correct answer is choice C.
Choice A rationale:
A lead level of 10 mcg/dL is above the CDC’s reference value of 3.5 mcg/dL and would require more immediate follow-up and intervention, not just rescreening in one year.
Choice B rationale:
A lead level of 18 mcg/dL is significantly elevated and would necessitate immediate medical intervention and frequent monitoring, rather than waiting a year for rescreening.
Choice C rationale:
A lead level of 4 mcg/dL is slightly above the CDC’s reference value of 3.5 mcg/dL. While it is concerning, it may be appropriate to rescreen in one year if no other risk factors are present.
Choice D rationale:
A lead level of 44 mcg/dL is dangerously high and requires urgent medical treatment and frequent follow-up, not just rescreening in one year.

Correct Answer is B
Explanation
Acute lead poisoning in toddlers can cause anorexia, as well as vomiting, abdominal pain, and constipation.
These symptoms can progress to seizures, coma, and even death if not treated promptly.
Choice A, increased urinary output, is not the correct answer because lead poisoning can cause a decrease in urinary output due to the effect of lead on the kidneys.
Choice C, diarrhea, is not the correct answer because lead poisoning is more likely to cause constipation than diarrhea.
Choice D, jaundice, is not the correct answer because jaundice is not a common finding in lead poisoning.
Jaundice is a yellowing of the skin and whites of the eyes caused by an excess of bilirubin in the blood, which is not directly related to lead poisoning.
Correct Answer is B
Explanation
Normal urine output for a child is 1-2 ml/kg/hr.
The child weighs 33 lb (15 kg), so their expected urine output over an 8-hour period would be between 120 mL and 240 mL.
The child’s urine output of 160 mL falls within this range.
Choice A, Notifying the provider, is not necessary because the child’s urine output
is within the normal range.
Choice C, Perform a bladder scan at the bedside, is not necessary because there is no indication of urinary retention.
Choice D, Providing oral rehydration fluids, is not necessary because the child’s urine output is within the normal range.
