NR 507 Week 6 Quiz (ii) Question 1. Question : Considering the pathophysiology of osteoporosis, what are the effects of extracellular signal regulated kinases (ERKs) and receptor activator of RA... NKL on osteoblasts and osteoclasts? ERKs increase the life span of osteoclasts and RANKL decreases the life span of osteoblasts. ERKs and RANKL increase the life span of osteoclasts and decrease the life span of osteoblasts. ERKs and RANKL increase the life span of osteoblasts and decrease the life span of osteoclasts. ERKs increase the life span of osteoblasts and RANKL decreases the life span of osteoclasts. Question 2. Question : A(n) _____ fracture is a fracture at a site of a preexisting bone abnormality, usually by a force that would not normally cause a fracture. idiopathic incomplete pathologic greenstick Question 3. Question : Which disorder is characterized by the formation of abnormal new bone at an accelerated rate beginning with excessive resorption of spongy bone? Osteomalacia Paget disease Osteoporosis Osteosarcoma Question 4. Question : Which statement is false about giant cell tumors? They are an overexpression of genes including osteoprotegerin ligand (OPGL). They are malignant, solitary, irregularly shaped tumors. They are typically located in the epiphysis in the femur, tibia, radius, and humerus. They are slow-growing tumors that extend over the articular cartilage. Question 5. Question : Rhabdomyolysis is characterized by : paralysis of skeletal muscles resulting from impaired nerve supply. smooth muscle degeneration resulting from ischemia. lysis of skeletal muscle cells through the initiation of the complement cascade. release of myoglobin from damaged striated muscle cells. Question 6. Question : Which of the following attaches skeletal muscle to bone? Student Answer: Tendon Ligament Bursa Mesentery Question 7. Question : By the time osteoporosis is visible on x-ray, up to ____% of bone has been lost. 30 40 50 60 Question 8.

Question 10. Question : Which serum laboratory test is elevated in all forms of osteogenesis imperfecta? : Phosphorus Calcium Alkaline phosphatase Total protein . Question 11. Question : The total mass of muscle in the body can be estimated from which serum laboratory test value? Albumin Blood urea nitrogen Creatinine Creatine : Question 12. Question : The _____ is cartilage that retains the ability to form and calcify new cartilage and deposit bone until the skeleton matures. epiphyseal line physeal plate epiphyseal cartilage metaphyseal plate Question 13. Question : In osteomyelitis, bacteria gain access to the subperiosteal space in the metaphysis, which is considered the “path of least resistance.” What factor makes this route for bacteria the path of least resistance? : Cortex of the bone in this area is porous or maze-like. Blood supply to the metaphysis is easily compromised. Macrophages and lymphocytes have limited access to the subperiosteal space. Bacteria usually spread down the medullary cavity of the bone. Question 14. Question : An insufficient dietary intake of vitamin _____ can lead to rickets in children. C B12 B6 D Instructor Explanation: Rickets results from either insufficient vitamin D, insensitivity to vitamin D, wasting of vitamin D by the kidney, or inability to absorb vitamin D and calcium in the gut. Question 15. Question : Cerebral palsy is usually a result of brain ischemia during birth. prematurity. congenital defects. genetic defect. Question 16. Question : Scleroderma is more common in women and is associated with a(n) X-linked recessive gene. X-linked dominant gene. virus. autoantibodies. Question 17. Question : Cutaneous vasculitis develops from the deposit of _____ in small blood vessels as a toxic response allergen. immune complexes IgE complement T lymphocytes Question 18. Question : _____ of the epidermis initiate immune responses and provide defense against environmental antigens. Langerhans cells Merkel cells Keratinocytes Melanocytes Question 19. Question : An older adult man states he has a sore above his lip that has not healed and is getting bigger. The nurse observes a red scaly patch with an ulcerated center and sharp margins. The nurse recognizes these features as commonly associated with Bowen disease, a form of Kaposi sarcoma. malignant melanoma. basal cell carcinoma. squamous cell carcinoma. Question 20. Question : Which cell is thought to be the progenitor cell of Kaposi sarcoma? Endothelial Keratinocyte Melanocyte Exothelial Question 21. Question : Rubeola is a highly contagious acute _____ disease in children. bacterial fungal yeast viral Rubeola is a highly contagious acute viral disease in children. Question 22. Question : What is a common source of tinea corporis? Question 23. Question : Which immunoglobulin is elevated in atopic dermatitis? IgA IgM IgE IgG Question 24. Question : Which of the following viral diseases has an incubation period of 14 to 21 days and a duration of 1 to 4 days? : Rubeola Rubella Roseola Varicella Question 25. Question : Which contagious disease creates a primary skin lesion that is a pinpointed macule, papule, or wheal with hemorrhagic puncture site? Pediculosis Tinea capitis Scabies Rubeola [Show More]
