An RN is caring for a patient with Tuberculosis who is to receive a new prescription for Isoniazid (INH). The nurse knows that INH can cause peripheral neuropathy. To help prevent this from happening, the nurse can ask the provider for:

A. Neutropenia refers to an abnormally low level of neutrophils in the blood. This condition can result from various factors, including severe infections, bone marrow issues, or certain medications. However, in the context of a severe bacterial infection, you would expect an increase in neutrophils, not a decrease.
B. Anemia is a condition characterized by a lack of healthy red blood cells to carry adequate oxygen to the body’s tissues. While infections can lead to anemia, it is not a direct indicator of white blood cell production or response to a bacterial infection.
C. Leukopenia refers to a decrease in the overall white blood cell count. Like neutropenia, it indicates a reduced ability to fight infection, which is not consistent with a severe bacterial infection where the body is actively trying to produce more white blood cells.
D. A "left shift" indicates the presence of increased immature neutrophils (such as band cells) in the blood, which occurs when the bone marrow releases these cells into circulation in response to a severe infection. This reflects the body’s effort to combat an infection, typically seen in bacterial infections.

A. This term refers to the passage of fresh blood through the anus, usually indicating lower GI bleeding (such as from the colon or rectum). It is a common and significant sign of GI bleeding.
B. Hypertension (high blood pressure) is generally not a sign of GI bleeding. In fact, GI bleeding typically leads to hypotension (low blood pressure) due to volume loss, making this choice incorrect.
C. Tarry stool (melena) indicates the presence of digested blood in the stool, typically resulting from upper GI bleeding. It appears black and sticky and is a common sign of GI bleeding.
D. This refers to vomiting that looks like coffee grounds, which indicates that blood has been present in the stomach and has undergone digestion. This is a classic sign of upper GI bleeding and is a significant symptom.
E. Hematemesis is the vomiting of blood, which can be bright red or resemble coffee grounds, depending on the source and severity of the bleeding. It is a common and serious sign of GI bleeding, particularly from the upper GI tract.
