ATI TEAS (Test of Essential Academic Skills) Version 7ReadingHard
A healthcare professional is reviewing a patient's lab results. The report shows: * **Hemoglobin (Hgb):** 10.5 g/dL (Normal range: 12.0-16.0 g/dL) * **Hematocrit (Hct):** 32% (Normal range: 37-47%) * **Red Blood Cell (RBC) Count:** 3.8 x 10^6/µL (Normal range: 4.2-5.4 x 10^6/µL) * **Mean Corpuscular Volume (MCV):** 85 fL (Normal range: 80-100 fL) Based on these results, what is the most likely overall condition indicated for this patient?
- AThrombocytopenia
- BPolycythemia
- CAnemia
- DLeukocytosis
Show answer & explanationAnswer & explanation
Correct answer: C. Anemia
All three key indicators for red blood cell mass (Hemoglobin, Hematocrit, and RBC Count) are below their respective normal ranges, which is characteristic of anemia.
Why the other options are wrong
- A. Thrombocytopenia refers to a low platelet count, which is not evaluated by these specific parameters.
- B. Polycythemia is characterized by *elevated* Hgb, Hct, and RBC count, which is the opposite of these results.
- D. Leukocytosis refers to an elevated white blood cell count, which is not evaluated by these specific parameters (though other blood tests would assess it).
Complete Blood Count (CBC) Interpretation
Analyzing the components of a CBC lab report, including red blood cells, white blood cells, and platelets, to assess overall health and diagnose conditions.
- Hgb, Hct, RBC indicate oxygen-carrying capacity.
- Low values often suggest anemia.
- Compare results to established normal ranges.
