A nurse is reviewing the plan of care for a client who has systemic lupus erythematosus (SLE). The client reports fatigue, joint tenderness, swelling, and difficulty urinating. Which of the following laboratory findings should the nurse anticipate? (Select all that apply)

A. While monitoring drug levels is important, sending a trough level before the initial dose is not standard practice. Trough levels are typically checked just before the next dose of a medication is given, especially for antibiotics like Gentamicin that require monitoring for potential toxicity. Therefore, this option is not the best immediate action.
B. While managing the environment and ensuring patient privacy is important, this option does not address any immediate medical needs related to starting the antibiotic infusion.
C. Educating the patient about potential side effects is essential for informed consent and patient safety. However, while important, this is not the most critical action to take prior to the infusion.
D. Before starting an antibiotic treatment, it is crucial to send a culture and sensitivity test to identify the specific pathogen causing the infection. This ensures that the selected antibiotic (Gentamicin) is appropriate for the identified bacteria, which is vital for effective treatment and to avoid antibiotic resistance.

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.
