مريض بالسكري يأخذ بيسوبرولول. لماذا يحتاج تعليماً خاصاً عن الهبوط؟

A diabetic client takes bisoprolol. Why does he need special teaching about hypoglycaemia?

1. Beta-blockers prevent hypoglycaemia entirely
2. They can mask palpitations and tremor
3. Beta-blockers raise glucose sharply after meals
4. Beta-blockers increase insulin absorption

Answer: B) They can mask palpitations and tremor. Beta-blockers mask adrenergic signs of hypoglycaemia such as palpitations and tremor, so clients rely on other cues and check glucose more often.
