A nurse is caring for a client who experienced a hemorrhage and received a blood transfusion. Which clinical manifestation should the nurse monitor to determine the effectiveness of the transfusion?

A) Correct. Arteriography is a radiographic procedure that uses contrast dye to visualize the blood vessels and can precisely identify the location and cause of bleeding, especially in cases of significant hemorrhage.

B) Incorrect. An electrocardiogram (ECG) is used to assess the heart's electrical activity and is not relevant to identifying the location of bleeding.

C) Incorrect. A chest X-ray may be performed for various respiratory or cardiovascular assessments, but it is not specific to identifying the cause of bleeding.

D) Incorrect. A complete blood count (CBC) provides valuable information about the client's red blood cells and hemoglobin levels but does not directly identify the exact location and cause of bleeding.

A) Incorrect. Hemoglobin levels may initially be normal or slightly decreased, but they would decrease later due to the body's compensatory response to dilute the remaining blood.

B) Incorrect. Platelet count may not be significantly affected in the early stages of hemorrhage. It is mainly responsible for clot formation, which becomes more relevant in the later stages.

C) Incorrect. In the early stages of hemorrhage, the white blood cell count is not significantly affected. It plays a role in fighting infection and inflammation.

D) Correct. Hematocrit levels represent the proportion of red blood cells in the blood. During early stages of hemorrhage, there is a loss of red blood cells, leading to decreased hematocrit levels.
