A client with multiple myeloma is admitted to the unit with a white blood cell count 2,200/mm3. Which of the following foods should the nurse prohibit family members from bringing to the client? A. Fried chicken from a fast food shop B. A gift basket of bagels C. A factory-sealed box of chocolates D. A fresh fruit basket

Which of the following diagnostic studies most likely would confirm a myocardial infarction? Serum myoglobin level Creatinine kinase (CK) White blood cell count (WBC) Troponin T levels

Troponin T levels Rationale: CK-MB elevates 4-6 hours after tissue necrosis. Troponin levels rise 6-8 hours after the infarct (tissue necrosis) but also can occur with other types of tissue damage. Myoglobin also elevates, but to a lesser degree. WBC levels elevate with an inflammatory response. Troponin levels are more elevated than are the other cardiac enzymes, are more specific to cardiac tissue, and rise 6-8 hours after the infarct (tissue necrosis).

What is White Blood Cell Count?

White Blood Cell Count, or WBC, is a medical measure of the number of circulating white blood cells in the body. White blood cells are key components of the immune system, commonly referred to as white blood cells because they appear light in color when seen through a microscope. The most common types of white blood cells are neutrophils, lymphocytes and monocytes. Neutrophils are responsible for engulfing and destroying bacteria and other foreign particles that enter the body. Lymphocytes help fight virus infections by recognizing foreign organisms and producing antibodies to destroy them. Monocytes help clean up dead cells and other debris from the bloodstream. A normal WBC count should range between 4000 to 11000 cells per microliter in adults. Abnormal WBC counts can indicate various health conditions ranging from bacterial infections to anaemia or even cancerous conditions like leukaemia or lymphoma. A high WBC count may be indicative of an infection, while a low count may suggest a weakened immune system due to age or illness such as HIV/AIDS or chemotherapy treatment for cancer patients. A doctor will usually order a complete blood count (CBC) test which measures not only the WBC count but also red cell counts (RBC), hemoglobin levels (HGB) and platelet counts (PLT). The CBC test also provides information on differential cell counts which gives specific numbers for each type of white cell present in circulation at any given time. This can give doctors more information on certain illnesses than just measuring an overall white cell count alone would provide. Overall, measuring the white cell count is important in diagnosing many different kinds of health problems ranging from minor infections to major diseases such as cancer or autoimmune disorders like lupus or rheumatoid arthritis.
