Final answer:
Hyperresonance to percussion should make you think of pneumothorax or emphysema.
Step-by-step explanation:
Hyperresonance to percussion is a physical examination finding that can be suggestive of certain lung conditions, such as pneumothorax or emphysema.
When percussion is performed on the chest, if there is hyperresonance, it may indicate that there is excessive air in the lungs or a loss of lung tissue elasticity. This can be seen in conditions like pneumothorax, where there is air trapped in the pleural space, or in emphysema, where there is destruction of the lung tissue.
Therefore, when hyperresonance to percussion is found, it should make you think of pneumothorax or emphysema as possible diagnoses.
