A 35-year-old female patient presents to the clinic with fatigue, pallor, and shortness of breath on exertion. Laboratory results reveal a hemoglobin level of 8 g/dL and a mean corpuscular volume (MCV) of 70 fL. Based on these findings, what is the most likely type of anemia?
Vitamin B12 deficiency anemia
Aplastic anemia
Iron deficiency anemia
Hemolytic anemia
The Correct Answer is C
A. Vitamin B12 deficiency anemia typically presents with larger red blood cells (high MCV) and neurological symptoms, which are not present in this case.
B. Aplastic anemia typically results in pancytopenia, and there is no mention of other blood cell line abnormalities.
C. Iron deficiency anemia is the most likely diagnosis, as it is characterized by low hemoglobin levels and a low MCV (microcytic anemia), which is consistent with the laboratory results.
D. Hemolytic anemia generally presents with elevated reticulocyte count and jaundice, neither of which are mentioned here.

Explanation
To calculate the total units of heparin per hour:
Multiply the patient’s weight (80 kg) by the dosage (18 units/kg/hour):
80 kg × 18 units = 1440 units/hour.
This means the patient should receive 1440 units of heparin per hour.
