A nurse is reviewing the results of laboratory screenings for a 9-month-old infant. Which of the following results should the nurse report to the provider?
Hemoglobin 12 g/dL
Iron 74 mcg/dL
Lead 18 mcg/dL
Hematocrit 35%
The Correct Answer is C
A. A hemoglobin level of 12 g/dL is within the expected range for an infant.
B. An iron level of 74 mcg/dL is normal for a 9-month-old.
C. This is the correct answer. A lead level of 18 mcg/dL is elevated (≥5 mcg/dL is concerning) and should be reported, as lead toxicity can lead to neurological damage.
D. A hematocrit of 35% is within the expected range for an infant.

Correct Answer is B
Explanation
A. Calcium – Spironolactone does not significantly impact calcium levels, so avoiding calcium supplements is unnecessary.
B. Potassium – This is the correct answer. Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Clients should avoid potassium supplements and potassium-rich foods to prevent dangerous elevations in serum potassium levels.
C. Iron – Spironolactone does not have a direct effect on iron metabolism, so iron supplementation is not contraindicated.
D. Magnesium – Although spironolactone does not have a strong impact on magnesium levels, excessive magnesium intake is not a primary concern with this medication.
