Which of the following conditions would tend to shift the point of maximal impulse (PMI) farther to the left?
1) Pulmonary emphysema
2) Collapse of the left lower lobe
3) Collapse of the right lower lobe
4) Right-sided tension pneumothorax

Question

Quizplus · Accepted Answer

Collapse of the left lower lobe (2) will cause the PMI to shift to the left, as will a right-sided tension pneumothorax (4). Pulmonary emphysema (1) and collapse of the right lower lobe (3) do not typically shift the PMI to the left. Therefore, the correct answer is (B)2 and 4 only.
