1.护理学基础
答案: A · Into the pocket of the lower eyelid
为什么是这个答案
Drops go into the lower conjunctival sac, which is less sensitive than the cornea. Pressing gently on the inner corner afterwards reduces drainage into the nose.
Smoking causes vasoconstriction and reduces tissue oxygen, slowing healing and increasing infection risk. Poor nutrition, diabetes, infection and steroids also impair healing.
答案
A · Smoking
4.临床护理
答案: B · Superior vena cava obstruction
为什么是这个答案
Superior vena cava obstruction prevents venous drainage from the head and arms. It is an oncological emergency; patients are positioned upright and need urgent specialist treatment.
答案: B · “If I miss a dose, I will take two the next day.”
为什么是这个答案
Doubling a missed warfarin dose raises the risk of bleeding. Patients are taught to follow the prescriber’s instructions for missed doses, and the other statements are correct.
答案
B · “If I miss a dose, I will take two the next day.”
14.优先排序与委派
答案: D · Trachea shifted away from the affected side, with low blood pressure
为什么是这个答案
In tension pneumothorax, trapped air pushes the mediastinum to the other side, reducing venous return and blood pressure. It is life-threatening and needs immediate decompression.
答案
D · Trachea shifted away from the affected side, with low blood pressure
Peak aminoglycoside levels are usually drawn about 30 minutes after a 30-minute infusion ends, to confirm the level is high enough to kill bacteria. Troughs, drawn just before the next dose, check for accumulation. Local protocols may differ, especially with once-daily dosing.
