NUR 631 Test 2
- What houses all of our genetic information in the cell?
Answer Nucleus
- Apoptosis
Answer process of programmed cell death
- What happens when a cell has impaired metabolism?
Answer Increase in waste products.
- How does water move between ICF and ECF
Answer Osmosis- diffusion of water across a selectively permeable membrane
- What happenes during alkalosis
Answer Ex. vomiting. body is getting rid of all the H leaving bicarb
- Diffusion
Answer the process by which molecules move from an area of higher concen- tration to an area of lower concentration
- Disorders that cause metabolic alkalosis
Answer Vomiting, by holding onto bicarb
- What protein denotes an increased risk of neural tube defects during an amniocentesis? 1 / 3
Answer Alpha fetoprotein
- What gets water moving in and out of cells?
Answer Osmosis of water through a selectively permeable membrane
- Down Syndrome
Answer a condition of intellectual disability (IQ <70)and associated physical disorders caused by an extra copy of chromosome 21.
Wide spaced eyes Flattened face almond eyes short neck small ears, Cardiac defects Cognitive Defects
- How can a mother prevent a child from getting Type 1 DM?
Answer Type 1 DM is autoimmune with a heredity component. It cannot be prevented.
- What genes maintain the cell during wound healing and inflammation.
Answer -
housekeeping gene
- Why do older adults take longer to heal?
Answer Comorbidities delay healings.
- What happens when a newborn does not have enough collectin proteins?-
Answer Collectins (collagen-containing C-type lectins) are a part of the innate immune system. They are at a higher risk for respiratory infections. 2 / 3
- Where do B lymphocytes mature?
Answer The B-lymphocytes become mature B cells in the bone marrow
- active aquired immunity
Answer Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response.Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen.
- Type 2 hypersensitivity reaction
Answer reaction is a form of immune-mediated reac- tion in which antibodies are directed against cellular or extracellular matrix antigens. This antibody-mediated response leads to cellular destruction, functional loss, or damage to tissues.
Antibodies attach the antigens on the cell surface
- Why do we give Rhogam?
Answer used to prevent Rh immunization, a condition in which an individual with Rh-negative blood develops antibodies after exposure to Rh-positive blood.
-at about 28 weeks of pregnancy and whenever your blood may mix with your baby's, like during prenatal tests or delivery -prevents hemolytic anemia in the newborn.
- What happens at a cellular level during organ rejection?
Answer The ability of recipient T cells to recognize donor-derived antigens, called allorecognition, initiates allograft rejection. Once recipient T cells become activated, they undergo clonal expansion, differentiate into effector cells, and migrate into the graft where they promote tissue destruction.
-Body releases TH1 cells that release natural killer cells, cytokines (inflammation),
