A nurse is reviewing the laboratory report of a preschooler during a well-child visit. Which of the following laboratory results should the nurse report to the provider?
Iron 100 mcg/dL.
Hemoglobin 8 g/dL.
Sodium 140 mEq/L.
Calcium 9 mg/dL.
The Correct Answer is B
Choice A rationale:
Iron 100 mcg/dL The normal range for serum iron levels can vary based on age and gender, but typically, a range of 50 to 150 mcg/dL is considered normal. The provided value of 100 mcg/dL falls within this range and is not a cause for concern. Elevated iron levels can be indicative of hemochromatosis or other disorders, but this value is not concerning.
Choice B rationale:
Hemoglobin 8 g/dL Hemoglobin levels can vary by age and gender, but in general, a hemoglobin level of 8 g/dL is low and suggestive of anemia, a condition characterized by a reduced ability of the blood to carry oxygen. Anemia can lead to fatigue, weakness, and other symptoms, and the nurse should report this finding to the healthcare provider for further evaluation and management.
Choice C rationale:
Sodium 140 mEq/L The normal range for serum sodium levels is typically around 135 to 145 mEq/L. The provided value of 140 mEq/L falls within this normal range and is not a cause for concern. Deviations from this range can indicate various conditions, including dehydration or overhydration, but this value is within an acceptable range.
Choice D rationale:
Calcium 9 mg/dL The normal range for serum calcium levels can vary, but generally, a range of 8.5 to 10.5 mg/dL is considered normal. The provided value of 9 mg/dL falls within this range and is not significantly abnormal. Abnormal calcium levels can be indicative of various conditions, including thyroid disorders or kidney problems, but this value is not concerning.

Correct Answer is ["B","C","E"]
No explanation
Correct Answer is A
Explanation
Choice A rationale:
A positive leukocyte esterase test indicates the presence of white blood cells (leukocytes) in the urine, which can be an indicator of a urinary tract infection (UTI). White blood cells are part of the body's immune response and their presence in the urine suggests inflammation and infection in the urinary tract.
Choice B rationale:
Deep gold-colored urine is not typically associated with a urinary tract infection. Normally, urine color can vary based on hydration, diet, and other factors, but color alone is not a reliable indicator of a UTI.
Choice C rationale:
The osmolality of 700 mOsm/L is not a specific finding related to urinary tract infections. Osmolality measures the concentration of particles in the urine and can vary based on hydration status. While it might be elevated in a concentrated urine sample, it is not a direct indicator of a UTI.
Choice D rationale:
A specific gravity of 1.015 is within the normal range and does not necessarily indicate a urinary tract infection. Specific gravity measures the concentration of solutes in the urine and can be influenced by hydration levels and kidney function. A UTI would primarily be indicated by the presence of white blood cells and other signs of infection in the urine.
