Which of the following is a common appearance of a patient with a Pulmonary Embolism?

A patient experiencing a pulmonary embolism typically presents with signs of anxiety and diaphoresis. This is largely due to the sudden onset of breathlessness and chest discomfort, which can provoke an anxious response as the body reacts to the hypoxemia and strain on the cardiovascular system. The fight-or-flight response triggers sweating and heightened alertness, contributing to the anxious demeanor.

In pulmonary embolism, the interruption of blood flow in the pulmonary arteries leads to decreased oxygenation and can manifest as a sense of impending doom, further increasing anxiety levels. Diaphoresis occurs as the body's sympathetic nervous system is activated, and patients may be seen sweating despite feeling cold or experiencing significant distress.

Other appearances, such as being calm and relaxed, would be atypical in this situation, as the clinical presentation of a pulmonary embolism is generally marked by distress. Similarly, pale and warm skin is inconsistent with the usual presentation, which might more accurately present with cool, clammy skin due to shock or impaired blood circulation. Lastly, confusion and hyperactivity are not characteristic; while some patients may exhibit confusion due to hypoxemia, hyperactivity would not typically be observed in the anxiety-ridden state that often accompanies a pulmonary embolism.
