A5 year old female spayed dachshund is admitted to the emergency room after blood work shows a pcv of 14%. based on her physical exam and remaining blood work, she is diagnosed with regenerative anemia. which of the following would least likely appear on her blood smear?
a. reticulocytes
b. eosinophils
c. band neutrophils
d. metarubricytes

Eosinophils.

Explanation:

Regenerative anemia may be defined as the medical condition in which the number of RBCs decreases. The less number of RBCs causes the more production of WBCs.

The patient shows PCV of 14% and shows regenerative anemia. The number of WBCs increases but the eosinophils numbers remain low as compared with other white blood cells. The eosinophils remains persistent in  the blood.

Thus, the correct answer is option (B).

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
