An activated monocyte is also known as a:
macrophage
lymphocyte
plasma cell
polymorphonuclear leukocyte
The Correct Answer is A
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.

Correct Answer is C
Explanation
A. 8:00 AM: This time is too early to draw a trough level for a medication administered at 10:00 AM. The trough level should be drawn just before the next dose is given to get the lowest concentration in the bloodstream.
B. 11:00 AM: This time is after the scheduled dose of vancomycin at 10:00 AM. Waiting until 11:00 AM would not provide an accurate trough level because the patient has already received the medication.
C. 9:00 AM: This is the correct time to obtain the patient's blood sample. It is one hour before the scheduled dose of vancomycin at 10:00 AM. Drawing the trough level at this time ensures it reflects the lowest concentration of the drug in the bloodstream.
D. 12:00 noon: This time is after the scheduled dose of vancomycin at 10:00 AM. Waiting until noon would not provide an accurate trough level because the patient has already received the medication.
Correct Answer is D
Explanation
A. Cushing's Syndrome: This is a condition caused by prolonged exposure to high levels of cortisol, a hormone produced by the adrenal glands. It is not related to kidney transplant or immunosuppressive therapy.
B. Hypersensitivity Reaction Type I: Also known as an immediate hypersensitivity reaction or an allergy, this type of reaction involves the immune system's exaggerated response to an allergen. Symptoms can range from mild to severe and occur quickly after exposure to the allergen. While allergies can cause various symptoms, they do not specifically represent rejection of a transplanted organ.
C. Chronic Graft Versus Host Rejection: This term is commonly associated with bone marrow or stem cell transplants. It occurs when immune cells from the donated tissue recognize the recipient's body as foreign and attack various organs or tissues. This process typically happens over a more extended period and is not directly related to the scenario described.
D. Acute Host Versus Graft Rejection: This occurs when the recipient's immune system recognizes the transplanted organ as foreign and launches an immune response against it. It can happen shortly after transplantation if the recipient's immune system is not adequately suppressed. In this case, stopping immunosuppressive therapy can trigger acute rejection, leading to the failure of the transplanted organ.
