Choose the one alternative that best completes the statement or answers the ques 1) A patient has a blood pressure of 134/70 per blood pressure cuff and a blood pressure of 90/50 per arterial line. The nurse should: A) Discontinue the arterial line immediately. B) Check the level of the transducer and relevel and rezero the system. C) Do nothing because this is a normal variation between the two methods of measurement. D) Begin the infusion of a dopamine drip. Answer: B Explanation: A) The placement of the transducer is essential for accurate measurement. It must be level with the phlebostatic axis in order for the monitoring system to be accurate. #1 is not done at this time because the system needs to be assessed first. #3 is not correct becaus there is only a 5 to 15 mm Hg difference between the direct and indirect measurements. #4 is not correct because more information and data are needed before a vasoactive dru is used.

Which value is the normal value? A) 100- 250 mm Hg B) 10- 250 dynes/sec/cm2 C) 400- 800 mm Hg D) 800- 1400 dynes/sec/cm2 Answer: B Explanation: A) The pulmonary system is a lo-wpressure system. The pressure of the vascular system is measured in dynes/sec/c2mdue to factors of flow, resistance, and time. #1 and #3 are not correct because mm Hg is used to measure pressure only. #4 is not correct because this the value for SVR.
