Incidence Correct! Morbidity

liquefaction occurs, and a foul odor is caused by bacterial action. The spread of tissue damage is rapid. Question 17 10 / 10 pts Match the type of cell injury to the cause. Some answers may be used more than once. (1 point each) Sunburn a. Physical agents Obesity b. Radiation injury Reactive oxygen species c. Chemical injury Low oxygen to tissues d. Biologic agents Fractures e. Nutritional imbalances OTC drugs f. Free radical injury Hypothermia g. Hypoxic cell injury Radiation treatment Lead toxicity Bacteria Question 18 10 / 10 pts List the 4 types of tissue found in the body. Pick 2 and give a description and example of each. Your Answer: Epithelial, Connective, Muscle, and Nervous Epithelial tissue covers the body's outer surface, lines inner surfaces, forms glandular tissue. It is avascular and can be squamous, cuboidal, and columnar. An example of this type of tissue is our skin. Muscle tissue functions to move our bones, pump blood through the heart, as well as contract blood vessels. Cardiac muscle tissue is an example of muscle tissue. Epithelial tissue covers the body’s outer surface, lines the inner surfaces, and forms glandular tissue. Epithelial tissue has three distinct surfaces and the basal surface is attached to an underlying

basement membrane. It is avascular, meaning without blood vessels. It receives oxygen and nutrients from the capillaries of the connective tissue on which it rests. Connective or supportive tissue is the most abundant tissue in the body. It connects and binds or supports the various tissues. Its cells produce the extracellular matrix that support and hold tissues together. Connective tissue is divided into two types: connective tissue proper and specialized connective tissue (cartilage, bone, and blood cells). The four types of connective tissue proper are loose (areolar), adipose, reticular, and dense connective tissue. The function of muscle tissue is to move the skeletal structures, pump blood through the heart, and contract the blood vessels and visceral organs. Muscle tissue can accomplish this by contraction. The two types of fibers that contract are called thin and thick filaments. Thin filaments are called actin, and the thick filaments are myosin. The three types of muscles tissue are skeletal, cardiac, and smooth. Nervous tissue is distributed throughout the body for communication. It provides the means for controlling body function and for sensing and moving about the environment. The two types of cells are neuron and glial cells. Neurons function is communication. Glial (meaning glue) cells support the neurons. Question 19 2.5 / 2.5 pts What is the most studied active transport system in the human body? Your Answer: The most studied active transport system is the sodium-potassium-ATPase pump. This pumo moves sodium from inside the cell to outside region, returning potassium to the inside of the cell. If this did not occur, sodium would remain in the cell, water would follow resulting in the cell to swell. Sodium-potassium (Na+/K+)-ATPase pump Question 20 2.5 / 2.5 pts What is the term to describe when cells use energy to move ions against an electrical or chemical gradient? Your Answer: Active transport Active transport Question 21 2.5 / 2.5 pts Give one function of a membrane potential: Your Answer: Generate nerve impulses Generate nerve impulse, muscle contractions, or cause hormone secretion Question 22 2.5 / 2.5 pts What is the term that describes a transport protein to help lipid soluble or large molecules pass through the membrane, that otherwise would not be able to get through? Your Answer: Facilitated diffusion facilitated diffusion

Module 2 Exam-

Question 5 10 / 10 pts

  1. When would surgery be appropriate in the treatment of cancer?
  2. Most chemotherapeutic drugs cause pancytopenia due to bone marrow suppression. What are the 3 possible adverse outcomes of this? Your Answer:
  3. Surgery can be used if the tumor is solid and small with well-defines margins. Also can be used to treat oncologic emergencies and be used as prophylactic measures.
  4. 3 possible adverse outcomes are neutropenia, anemia, thrombocytopenia. **1. Surgery is often the first treatment for solid tumors. If the tumor is small with well-defined margins, it can be removed completely. It is also used for oncologic emergencies and prophylactic surgery in high risk patients.

False False, cell proliferation Question 8 2.5 / 2.5 pts What are two important properties that stem cells possess? Your Answer: Stem cells possess self-renewal and potency. Self renewal means that they can undergo mitotic divisions while maintaining undifferentiated state. Potency is the differentiation potential of stem cells. Potency and self-renewal

Question 19 10 / 10 pts Short answer A 40-year-old man presents with cough and shortness of breath. After an H&P and chest films, it is determined he has pneumocystis carinii pneumonia (PCP). The provider does an HIV test, which is positive. Upon further testing, the man’s CD4+ cell count is 100 cells/μL and his viral load is 250, copies/mL. (1) Why did the provider do an HIV test after the man was diagnosed with PCP? (2) What classification does this man fall into based on his CD4+ count and symptomatology, and why? Your Answer:

  1. PCP is a lung infection that affects people with weakened immune systems, such as those infected with HIV. It is listed as an opportunistic infection.
  2. Overt AIDS. Patient's CD4+ cell count is below 200 cells/uL. Patient also presented with an AIDS- defining illness, such as PCP. (1) Opportunistic infections are those common organisms that do not produce infection without impaired immune function. (2) The last phase, or AIDS illness, occurs when the CD4+ cell count falls to less than 200 cells/μL or exhibits an AIDS-defining illness. The risk of opportunistic infections and death increases significantly when the CD4+ cell count falls below 200 cells/μL.
