Nitroprusside purpose - Answer- decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action - Answer- contractility Dopamine at a low-end dose "renal dose" - Answer- 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose - Answer- 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose - Answer- greater than 10mcg/kg/min vasoconstriction and increases BP Dopamine and Levophed inf...

1. A nurse is assessing a client who is 12hr postoperative following a colon resection. Which of the following findings should the nurse report to the surgeon? a. Heart rate 90/min b. Absent bowel sounds c. Hgb 8.2 g/dl d. Gastric pH of 3.0 Rationale: Normal Hgb is 13-18M g/dl, 12-16 g/dl. This may indicate a possible hemorrhaging. 2. A nurse is caring for a client who has diabetes insipidus. Which of the following medications should the nurse plan to administer? a. Desmopressin b. Reg...
