NURS 6501 Pathophysiology Final Exam

A nucleus A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? Nucleuolus A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information be contained? Ligands Which of the following can bind to plasma membrane receptors? Integral membrane proteins Which of the following can remove proteins attached to the cell's bilayer by dissolving the layer itself? Decreased fibronectin A nurse is reviewing a report from a patient with metastatic cancer. What alternation in the extracellular matrix would support the diagnosis of metastatic cancer? Paracrine Pancreatic beta cells secrete insulin, which inhibits secretion of glucagon from neighboring alpha cells. This action is an example of which of the following signaling types? ATP An athlete runs a marathon, after which his muscles feel fatigued and unable to contract. The athlete asks the nurse why this happened. The nurse's response is based on the knowledge that the problem is a result of a deficiency of: Citric acid cycle Which phase of catabolism produces the most ATP? Digestion, glycolysis, oxidation and the citric acid cycle A nurse is teaching the staff about the phases of cellular catabolism. Which phases should the nurse include? Anaerobic glycolysis A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? Diffusion A faculty member asks a student to identify the appropriate term for the movement of a solute from an area of greater to lesser concentration. Which answer indicates the nursing student understood the teaching? Plasma proteins a nurse is reading a chart and sees the term oncotic pressure. The nurse recalls that oncotic pressure (colloid osmotic pressure) is determined by: Osmolality A patient has a body fluid of 300 mOsm/kg. This lab result is measuring: Hydrostatic pressure
