ATI TARGETED REVIEW ASSIGNMENTS FOR FINAL EXAM PRACTISE.

A nurse is caring for a client who requires nasogastric suctioning. Which of the following sets of laboratory results indicate that the client has metabolic alkalosis? A. pH 7.51, PaO2 94 mm Hg, PaCO2 36 mm Hg, HCO3- 31 mEq/L B. pH 7.48, PaO2 89 mm Hg, PaCO2 30 mm Hg, HCO3- 26 mEq/L C. pH 7.31, PaO2 77 mm Hg, PaCO2 52 mm Hg, HCO3- 23 mEq/L D. pH 7.26, PaO2 84 mm Hg, PaCO2 38 mm Hg, HCO3- 20 mEq/L – Ans - A. pH 7.51, PaO2 94 mm Hg, PaCO2 36 mm Hg, HCO3- 31 mEq/L A nurse is assessing a client who has hyperkalemia. Which of the following findings should the nurse expect? A. Decreased muscle strength B. Decreased gastric motility C. Increased heart rate D. Increased blood pressure ans- A. Decreased muscle strength A nurse is assessing a client who has dehydration. Which of the following assessments is the priority? A. Skin turgor B. Urine output C. Weight D. Mental status Ans- D. Mental status A nurse is reviewing the ABG results for four clients. Which of the following should the nurse identify as metabolic acidosis? A. pH 7.51, PaO2 94 mm Hg, PaCO2 38 mm Hg, HCO3- 29 mEq/L B. pH 7.48, PaO2 89 mm Hg, PaCO2 30 mm Hg, HCO3- 24 mEq/L C. pH 7.36, PaO2 77 mm Hg, PaCO2 52 mm Hg, HCO3- 26 mEq/L D. pH 7.26, PaO2 84 mm Hg, PaCO2 38 mm Hg, HCO3- 20 mEq/L Ans - D. pH 7.26, PaO2 84 mm Hg, PaCO2 38 mm Hg, HCO3- 20 mEq/L A nurse is reviewing the laboratory report of a client who has fluid volume excess. Which of the following laboratory values should the nurse expect? A. Hgb 20 g/dL B. Hct 34% C. BUN 25 mg/dL D. Urine specific gravity 1.050 - B. Hct 34% Rationale: The nurse should identify that a client who has fluid volume excess can have a Hct level that is below the expected reference range of 37% to 47% for females or 42% to 52% for males. Fluid volume excess can cause hemodilution and a decreased hematocrit level. A nurse is assessing a client who has respiratory acidosis. Which of the following findings should the nurse expect? A. Confusion B. Peripheral edema C. Facial flushing and warmth D. Hyperreflexia Ans- A. Confusion Rationale: A client who has respiratory acidosis will experience confusion from a lack of cerebral perfusion. If acidosis is not reversed, the client's level of consciousness will decrease, and coma can occur. A nurse is preparing to administer oral potassium to a client who has a potassium level of 5.5 mEq/L. Which of the following actions should the nurse take first?
