A patient is diagnosed with a low iron count. The nurse would be alert for which finding associated with this condition?
1. Increased carbon dioxide in the blood
2. Nausea
3. Anxiety
4. Poor tissue oxygenation
4
Rationale 1: Low iron would not increase carbon dioxide levels in the blood.
Rationale 2: Nausea is not generally associated with low iron count.
Rationale 3: Anxiety is not generally associated with low iron count.
Rationale 4: Oxygen is carried in the blood either bound to hemoglobin or dissolved in the plasma. Oxygen is not very soluble in water, so almost all oxygen that enters the blood from the respiratory system is carried to the cells of the body by hemoglobin.
