( PROVEN ITS ALL YOU NEED TO EXCEL IN YOUR EXAMS) . A eukaryotic cell is undergoing DNA replication. In which region of the cell would most of the genetic information be contained? a. Mitochondria b. Ribosome c. Nucleolus d. Nucleus Cytoplasm 4. itself? 5. REF: p. 9 6. 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?a. NURSINGTB.COM Decreased fibronectin b. Increased collagen c. Decreased elastin d. Increased glycoproteins 7. 8. REF: p. 12 9. In cellular metabolism, each enzyme has a high affinity for a: a. solute. b. substrate. c. receptor. d. ribosome. ANS: B Each enzyme has a high affinity for a substrate, a specific substance converted to a product of the reaction. Cellular metabolism is not dependent on an attraction between an enzyme and any of the remaining options. 10. 11. 12. include? a. Digestion, glycolysis, oxidation, and the citric acid cycle b. Diffusion, osmosis, and mediated transport c. S phase, G phase, and M phase d. Metabolic absorption, respiration, and excretion ANS: A Only digestion, glycolysis, oxidation, and the citric acid cycle are the phases of cellular catabolism. REF: p. 16 13. A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? a. Electron-transport chain b. Aerobic glycolysis c. Anaerobic glycolysis d. Oxidative phosphorylation ANS: C When no oxygen is available, anaerobic glycolysis occurs. The electron-transport chain is part of the citric acid cycle. Aerobic glycolysis involves the presence of oxygen. Oxidative phosphorylation is the mechanism by which the energy produced from carbohydrates, fats, and proteins is transferred to ATP. It is not part of muscle performance. REF: NURSINGTB.COM p. 16 14. 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? a. Osmosis b. Diffusion c. Hydrostatic pressure d. Active transport ANS: B Diffusion is the movement of a solute molecule from an area of greater solute concentration to an area of lesser solute concentration through a permeable membrane. Osmosis is the movement of water across a semipermeable membrane from a region of higher water concentration to one of lower concentration. Hydrostatic pressure is the force of fluid against a cell membrane. In active transport, molecules move up a concentration gradient. REF: p. 19 15. Which description accurately describes electrolytes? a. Small lipid-soluble molecules b. Large protein molecules c. Micronutrients used to produce ATP d. Electrically charged molecules ANS: D Electrolytes are electrically charged molecules. They are not lipid soluble, they are not made up of protein, and they do not play a role in ATP production. REF: p. 18 16. A nurse is reading a chart and sees the term oncotic pressure. The nurse recalls that oncotic pressure (colloid osmotic pressure) is determined by: a. the concentration of sodium. b. plasma proteins. c. hydrostatic pressure. d. the availability of membrane transporter proteins. ANS: B Oncotic pressure is determined by the effect of colloids or plasma proteins. The concentration of sodium plays a role in tonicity. Hydrostatic pressure is the force within a vessel. Membrane transporter proteins are involved in active transport within a concentration gradient. REF: p. 20 17. A patient has a body fluid of 300 mOsm/kg. This lab result is measuring: a. osmolality. b. osmolarity. c. osmotic pressure. d. oncotic pressure. ANS: A NURSINGTB.COM Osmolality measures the number of milliosmoles per kilogram of water, or the concentration of molecules per weight of water, while osmolarity measures the number of milliosmoles per liter of solution, or the concentration of molecules per volume of solution. Osmotic pressure is the amount of hydrostatic pressure required to oppose the osmotic movement of water. Oncotic pressure is from plasma proteins, not body fluids. REF: p. 19
