A 65-year-old female is diagnosed with metastatic breast cancer. Which of the following cells would be produced in large quantities to eliminate the tumor cells?
Neutrophils
Eosinophils
Platelets
Macrophages
The Correct Answer is D
A. Neutrophils: Neutrophils are a type of white blood cell that plays a key role in the immune system's response to infections, particularly bacterial infections. They are not primarily involved in eliminating cancer cells.
B. Eosinophils: Eosinophils are another type of white blood cell. They are important in the immune response to parasites and are also involved in allergic reactions. While they have a role in the immune system, they are not the primary cells involved in eliminating cancer cells.
C. Platelets: Platelets, also known as thrombocytes, are not cells but rather small cell fragments. They are essential for blood clotting and do not directly participate in the immune response against cancer cells.
D. Macrophages: Macrophages are a type of white blood cell that are involved in the immune system's defense against cancer. They are phagocytes, which means they engulf and digest cellular debris, foreign substances, and cancer cells. Macrophages play a crucial role in the body's immune surveillance and response against cancer.

Correct Answer is A
Explanation
A. Ceftaroline (Teflaro) is a fifth-generation cephalosporin antibiotic that is effective against MRSA (Methicillin-Resistant Staphylococcus Aureus). It's the first cephalosporin in its class with this capability, making it a valuable choice in treating MRSA infections.
B. Cefepime (Maxipime) is a fourth-generation cephalosporin that does not have specific activity against MRSA.
C. Ceftriaxone (Rocephin) is a third-generation cephalosporin, effective against a wide range of bacteria, but not specifically targeted at MRSA.
D. Cephalexin (Keflex) is a first-generation cephalosporin, primarily effective against Gram-positive bacteria, but not effective against MRSA.
Correct Answer is A
Explanation
A. Macrophage: This is the correct answer. An activated monocyte is also known as a macrophage. Monocytes are white blood cells that can mature into macrophages when they move into tissues. Macrophages play a crucial role in the immune system by phagocytosing (engulfing and digesting) pathogens and cellular debris.
B. Lymphocyte: Lymphocytes are another type of white blood cell that plays a central role in the immune system. They include B cells, T cells, and natural killer cells. Lymphocytes are primarily involved in adaptive immune responses, such as antibody production (B cells) and cell-mediated immune responses (T cells).
C. Plasma Cell: Plasma cells are a type of B cell that produces antibodies (immunoglobulins). They are involved in the adaptive immune response, specifically in the production of antibodies that target specific pathogens.
D. Polymorphonuclear Leukocyte: This term typically refers to a group of white blood cells that have a multi-lobed nucleus. Neutrophils, eosinophils, and basophils are examples of polymorphonuclear leukocytes. They are involved in innate immune responses, including the phagocytosis of pathogens.
