【ISPN/RN考题解析】只记住了钾钠镁？孩子还是太天真了

听说最近大家已经被安排开学了！优秀的小伙伴们最近都在家默默修炼！有没有已经做在ISPN课程中火力全开的嘞~快举起小手让我康康呀

众所周知数值范围的题目大概是两极分化最严重的一类题目，能记住的说真简单，记不住的说真难，还有一种记得住但是混的一塌糊涂的只能说一句：“我太难了。”

今天的题目估计是雪上加霜型的题目，只记住了钾钠镁的范围？还差得远哦孩子，还记住了钙氯磷？恩恩能应付一部分了…BUN，Creatine，AST/ALT，PLT这些的正常值呢？

地高辛的正常药物浓度，苯妥英钠的药物浓度你都清楚么？

今天的这个题目就是来给大家扩展一下知识面的

来，看看哪个小机灵能答对今天的题目，加鸡腿哦

今日例题

The charge nurse in an intensive care unit is rounding and reviewing hemodynamic data for clients in the unit. Which client requires immediate intervention?

1.Client who is septic due to pneumonia with central venous pressure of 6 mm Hg

2.Client who recently underwent a coronary artery bypass graft with cardiac output of 5 L/min

3.Client with a gastrointestinal bleed and mean arterial pressure of 58 mm Hg

4.Client with an adrenal gland tumor and blood pressure of 168/95 mm Hg

重点词汇解析

intensive care unit 重症监护室，ICU的全称

Hemodynamic 血液动力学的

central venous pressure 中心静脉压

coronary artery bypass graft 冠状动脉搭桥手术，CABG的全称

mean arterial pressure 平均动脉压

先来看一组数据的正常范围

Hemodynamic parameters

_

Hemodynamic parameters

Clinical significance

Cardiac output

(CO)

4-8 L/min

Volume of blood ejected by heart

Indicates cardiac function

Cardiac index

(CI)

2.2-4.0 L/min/m2

CO adjusted for body surface area

More precise measure of cardiac function

Central venous pressure

(CVP)

2-8 mm Hg

Measure of right ventricular preload (pressure in the ventricle after filling)

Indicates fluid volume status

Mean arterial pressure
(MAP)

70-105 mm Hg

Average arterial pressure

Indicates perfusion of organs & tissues

MAP = (SBP + [2 × DBP])/3

Pulmonary artery wedge pressure

(PAWP)

6-12 mm Hg

Measure of left ventricular preload

Indicates left-sided heart function

Systemic vascular resistance

(SVR)

800-1200 dynes/sec/cm5

Measure of vascular resistance
(eg, vessel dilation or constriction)

DBP = diastolic blood pressure; SBP = systolic blood pressure.

答案自己就出来啦，选3

注：systolic blood pressure (SBP) and diastolic blood pressure (DBP)

(选项1 和 2) 中心静脉压6 mm Hg 以及心输出量5 L/min都是在正常范围内的。

(Option 4) 血压 168/95 mm Hg有升高趋势，需要进一步评估。但是低MAP由于有组织缺血坏死的可能，是最优先要处理的患者
