رجل عمره ٤١ سنة كان عنده إسهال قبل أسبوعين، والآن صار عنده ضعف يبدأ من القدمين ويصعد للأعلى خلال أيام، مع تنميل وغياب المنعكسات. لا يستطيع الوقوف، والتنفس ٢٢، والتشبع ٩٦٪. ما أهم مراقبة تمريضية؟

A 41-year-old man had diarrhoea two weeks ago and now has weakness starting in the feet and ascending over days, with tingling and absent reflexes. He cannot stand; RR 22, SpO2 96%. What is the most important nursing monitoring?

1. Hourly blood glucose readings only
2. Hand-grip strength once a day
3. Frequent vital capacity checks
4. Urine colour and odour each shift

Answer: C) Frequent vital capacity checks. This is Guillain-Barré syndrome. The greatest danger is respiratory muscle weakness, so vital capacity is measured regularly, and a fall (for example below 20 mL/kg) prompts ventilation. Autonomic instability is also monitored.
