1. A 12-year-old male is diagnosed with Klinefelter syndrome. His karyotype would reveal which of the following? a. XXY 2. The nurse is teaching staff about the most common cause of Down syndrome. What is the nurse describing? a. Maternal nondisjunction 3. A nurse is discussing the movement of fluid across the arterial end of capillary membranes into the interstitial fluid surrounding the capillary. Which process of fluid movement is the nurse describing? a. Hydrostatic pressure 4. What principle should the nurse remember when trying to distinguish aging from disease? a. It is difficult to tell the difference because both processes are believed to result from cell injury. 5. What causes the rapid change in the resting membrane potential that initiates an action potential? a. Sodium gates open, and sodium rushes into the cell, changing the membrane potential from negative to positive. 6. During childhood, the thymus decreases in size, and this is referred to as _____ atrophy. a. Physiologic 7. Sodium and water accumulation in an injured cell are a direct result of: a. Decreased ATP production 8. A 50-year-old male was recently diagnosed with Huntington disease. Transmission of this disease is associated with: a. Delayed age of onset 9. What is the diagnosis of a 13-year-old female who has a karyotype that reveals an absent homologous X chromosome with only a single X chromosome? Her features include a 1 This study source was downloaded by from CourseH on :57:33 GMT -05:00 NURS 6501N- 13 Advanced Pathophysiology Week 1 Quiz short stature, widely spaced nipples, reduced carrying angle at the elbow, and sparse body hair. a. Turner Syndrome 10. What is the role of cytokines in cell production? a. Provide growth factor for tissue growth and development 11. A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information be contained? a. Nucleolus 12. A patient has severe mental retardation caused by a deletion of part of chromosome 5. What genetic disorder will the nurse see documented in the chart? a. Cri du chat syndrome 13. The student is reviewing functions of the cell. The student would be correct in identifying the primary function of the nerve cell as: a. Communication 14. How are potassium and sodium transported across plasma membranes? a. By adenosine triphosphate enzyme (ATPase) 15. After a geneticist talks to the patient about being a chromosomal mosaic, the patient as the nurse what that means. How should the nurse respond? You may ____ genetic disease(s). a. Have a mild form of the 16. A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? a. Anaerobic glycolysis 17.

A patient has a heart attack that leads to progressive cell injury that causes cell death with severe cell swelling and breakdown of organelles. What term would the nurse use to define this process? a. Necrosis 19. A nurse reading the chart and sees the term oncotic pressure. The nurse recalls that oncotic pressure (colloid osmotic pressure) is determined by: a. Plasma proteins 20. An aide asks the nurse why people who have neurofibromatosis will show varying degrees of the disease. Which genetic principle should the nurse explain to the aide? a. Expressivity 21.
