A nurse is caring for a client who has Meniere's disease. The nurse identifies which of the following manifestations is caused by an excessive accumulation of endolymph fluid?

A. Phlebotomist - Phlebotomists are trained in drawing blood and handling specimens but are not typically trained to verify blood products for transfusion.

B. Assistive personnel - Assistive personnel (e.g., nursing assistants) do not have the required training or authority to verify blood products for transfusion.

C. Senior nursing student - Although a senior nursing student may have some clinical experience, they do not have the qualifications or the responsibility required for this critical safety task.

D. Oncology nurse - An oncology nurse is a registered nurse with specialized training and experience in administering blood products and managing the associated risks, making them qualified to double-check blood labels and patient identification.

A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.

B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.

C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.

D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.
