Question:

Which of the following compensatory actions by the body would occur if a client were in respiratory acidosis? 

1. Excretion of bicarbonate (HCO3-) by the kidneys. 

2. Retention of HCO3- by the kidneys. 

3. Increase in respiratory rate by the lungs.

4. Decrease in respiratory rate by the lungs.

Answer:2

The compensatory mechanism for respiratory acidosis is the renal system. In respiratory acidosis, the kidneys will conserve HCO3- in an attempt to correct the acidosis. Excretion of HCO -would exacerbate the body’s acidosis. The lungs cannot compensate for a problem that arises in the respiratory system.

问题：

如果患者患有呼吸性酸中毒，身体会采取以下哪种代偿措施？

1.肾排泄碳酸氢盐(HCO3-)。

2.肾脏对HCO3-的滞留。

3.肺部呼吸频率增加。

4.肺部呼吸频率降低。

答案：2

呼吸性酸中毒的代偿机制是肾脏系统。在呼吸性酸中毒中，肾脏会保存HCO3-以纠正酸中毒。HCO-的排泄会加剧身体的酸中毒。肺部无法补偿呼吸系统出现的问题。
