Question

which of the following conditions is most likely to produce hyperresonant percussion?
pneumothorax
pneumonia
atelectasis
pleural effusion
question 50 (2 points)
which of the following is not a classic sign of acute arterial obstruction?
cold extremity
weak or absent pulse
high - grade fever
cyanosis

Explanation:

1. For the first question, hyperresonant percussion is associated with increased air - containing spaces in the chest. Pneumothorax is a condition where air accumulates in the pleural space, leading to hyperresonant percussion. Pneumonia causes consolidation (less air, more fluid/solid tissue), atelectasis is collapsed lung tissue (less air), and pleural effusion is fluid in the pleural space (less air - space for resonance).
2. For the second question, classic signs of acute arterial obstruction include cold extremity due to lack of blood - flow (which carries heat), weak or absent pulse as blood flow is blocked, and cyanosis due to lack of oxygenated blood supply. High - grade fever is not a typical sign of acute arterial obstruction as it is more related to inflammatory or infectious processes rather than arterial blood - flow issues.

Answer:

1. Pneumothorax
2. High - grade fever
