A nurse is reviewing the laboratory results of an adolescent who has chronic glomerulonephritis. Which of the following findings should the nurse expect?
BUN 50 mg/dL.
Serum phosphorus 4.0 mg/dL.
Serum potassium.8 mEq/L.
Absence of proteinuria.
The Correct Answer is A
Chronic glomerulonephritis is a condition that causes inflammation of the glomeruli, which are tiny filtering units in the kidneys.
This can lead to poor kidney function and an increase in waste products in the bloodstream.
Blood urea nitrogen (BUN) is a waste product that is normally filtered by the kidneys and excreted in urine.
A BUN level of 50 mg/dL is higher than the normal range, indicating poor kidney function.
Choice B is incorrect because a serum phosphorus level of 4.0 mg/dL is within
the normal range for adults.
Choice C is incorrect because a serum potassium level of.8 mEq/L is within the normal range for adults.
Choice D is incorrect because proteinuria (the presence of protein in urine) is a
common finding in glomerulonephritis.

Correct Answer is C
Explanation
The correct answer ischoice 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.
