5.Medium
Why is a non-selective beta-blocker such as propranolol usually avoided in a patient with asthma?
- AIt raises the heart rate sharply during an acute asthma attack
- BIt thickens airway mucus by drying the airways
- CIt makes inhaled corticosteroids work too strongly
- DIt can cause bronchospasm by blocking beta-2 receptors
6.Medium
Why does a large, rapidly forming pericardial effusion lower the blood pressure?

- BA new pulmonary embolism
- CLow blood glucose from fasting
- DAn allergic reaction to the commode
8.Hard
