CHAPTER 8 LECTURE QUIZ 1. The nurse is caring for a client with worsening respiratory acidosis. Which of these interventions does the nurse anticipate if the client's condition continues to deteriorate? A. Mechanical ventilation B. Reducing the amount of supplemental oxygen C. Resolution of the underlying emotional cause D. Introduction of large muscle exercise 2. Body weight consists of which percentage of body water? A. 7% B. 40% C. 60% D. 90% 3. The nurse is caring for a client who has developed hypoxemia and tissue hypoxia. Which of these interventions does the nurse set as a priority intervention? A. Administration of supplemental oxygen B. Rebreathing into a paper bag C. Alternating deep breathing with holding one’s breath D. Rapid, short, shallow breaths 4. The nurse who is providing care for several clients recognizes which client is at the highest risk for developing an acid–base imbalance? A. A client who is being treated for acute kidney injury and who requires dialysis B. A client who had an anaphylactic reaction to an insect sting and required resuscitation C. A client who is receiving intravenous penicillin for the treatment of primary syphilis D. A client who has a rectovaginal fistula that will require surgery 5. The nurse is evaluating a client’s blood gasses. The client has a pH of 7.35. How does the nurse interpret this value? A. It indicates alkalosis. B. It indicates acidosis. C. It is within a normal range. D. It indicates a respiratory problem 6. The nurse has just received the laboratory results of a client’s calcium level. The nurse identifies a normal calcium level as: A. 8.5 to 10.5 mg/dl (2.25 mmol/l to 2.6 mmol/l) B. 12.0 to 15.0 mg/dl (3.0 to 3.75 mmol/l) C. 13.5 to 14.5 mg/dl (3.38 to 3.63 mmol/l) D. 3.5 to 5.3 mg/dl (0.88 to 1.32 mmol/l) 7. The nurse recognizes the role of the lungs in acid-base balance is regulation of which of the following? A. CO2 B. H2O C. HCO3 D. Hydrogen 8. The renal control mechanism of restoring the acid-base balance is accomplished through which process? A. Reabsorption of HCO3 and excretion of H+ restores acid-base balance through the renal control mechanisms. B. Regulation of the production of carbonic acid C. Reabsorption of hydrogen and excretion of carbonic acid D. Stimulation of the chemoreceptors in the brain stem 9. Pressure generated as water moves across a membrane is also known as which of the following? A. Osmotic pressure B. Hydrostatic pressure C. Filtration pressure D. Lymphatic pressure 10. A client has been diagnosed with metabolic acidosis. What assessment finding does the nurse expect? A. Increased pH above 7.45 B. Increased PCO2 above 45 mm/Hg (5.99 kPa) C. Decreased pH below 7.35 D. Decreased PCO2 below 35 mm/Hg (4.66 kPa)
