                  Rationale: Continuous renal replacement therapy (CRRT) provides continuous
               ultrafiltration of extracellular fluid and clearance of urinary toxins over a period of 8
               to 24 hours; it is used primarily for clients with acute kidney injury (AKI) or critically
               ill clients with chronic kidney disease (CKD) who cannot tolerate hemodialysis.
               Water, electrolytes, and other solutes are removed as the client’s blood passes
               through a hemofilter. If CRRT does not require a hemodialysis machine, the client’s
               MAP needs to be maintained above 60 mm Hg, and arterial and venous access sites
               are necessary. The SBP, DBP, and CVP may be monitored but each of these measures
               a component of the cardiovascular status rather than the complete cardiac cycle.
                  Test-Taking Strategy: Note the strategic words, most important. Recall that the
               mean arterial pressure is a measure that takes into account the complete cardiac
               cycle and is therefore the umbrella option that encompasses all other options.

                   865. Answer: 2


                  Rationale: A change in vital signs may be a late sign of increased intracranial
               pressure. Trends include increasing temperature and blood pressure and decreasing
               pulse and respirations. Respiratory irregularities also may occur.
                  Test-Taking Strategy: Focus on the subject, signs of increased intracranial
               pressure. If you remember that the temperature rises, you are able to eliminate
               options 3 and 4. If you know that the client becomes bradycardic, or know that the
               blood pressure rises, you are able to select the correct option.

                   866. Answer: 1, 2, 3


                  Rationale: An anaphylactic reaction requires immediate action, starting with
               quickly assessing the client’s respiratory status. Although the PHCP and the Rapid
               Response Team must be notified immediately, the nurse must stay with the client.
               Oxygen is administered and an IV of normal saline is started and infused per PHCP
