A patient presents with fatigue, headache, and decreased exercise tolerance. Their hemoglobin concentration has declined gradually over several weeks. Which of the following factors is LEAST likely to be the cause of these symptoms? A) Anemia. B) Vasoconstriction due to increased red blood cell count. C) Decreased tissue oxygen levels. D) The body's compensatory response to hypoxia.
Understand the Problem
This is a question about the possible causes and effects related to a patient's symptoms like fatigue, headache, and decreased exercise tolerance, especially in the context of declining hemoglobin levels. The question asks you to identify the option that is LEAST likely to contribute to these symptoms.
Answer
Vasoconstriction due to increased red blood cell count.
The factor LEAST likely to be the cause of the patient's symptoms is vasoconstriction due to increased red blood cell count. The patient's symptoms indicate anemia. Anemia is related to a decreased, not increased, red blood cell count.
Answer for screen readers
The factor LEAST likely to be the cause of the patient's symptoms is vasoconstriction due to increased red blood cell count. The patient's symptoms indicate anemia. Anemia is related to a decreased, not increased, red blood cell count.
More Information
The symptoms described are consistent with anemia. Increased red blood cell count would cause vasodilation, not vasoconstriction.
Tips
Read the question carefully. The question asks for the LEAST likely answer, meaning you are looking for the option that does not fit the clinical picture.
