What condition is indicated when a patient with a chest tube experiences sharp,stabbing chest pain without a change in pulse or blood pressure?

A) Pneumonitis
B) Tube displacement
C) A myocardial infarction
D) A tension pneumothorax

Sharp,stabbing chest pain with or without decreased blood pressure and increased heart rate may indicate a tension pneumothorax.A chest tube is not an expected treatment for pneumonitis.Tube displacement is an unexpected outcome and can lead to increased pneumothorax.Immediately apply pressure over the chest tube insertion site.Myocardial infarction pain is expressed as "crushing" or "pressure" over the sternal area.
