What are classic signs of shock in the field?

• A. Warm, Flushed Skin, Strong Pulse
• B. Cool, Clammy Skin; Rapid, Weak Pulse; Rapid Breathing
• C. Pale but Warm Skin; Slow Pulse
• D. Bright Pink Mucous Membranes and High Blood Pressure

Answer: (D)

In shock, the body redirects blood to vital organs, so you see signs of poor perfusion. The skin becomes cool and clammy from vasoconstriction, the heart pumps faster but with less effective force producing a rapid, weak pulse, and breathing often becomes rapid as the body tries to deliver more oxygen. So the classic field signs are cool, clammy skin; a rapid, weak pulse; and rapid breathing.

Warm, flushed skin with a strong pulse doesn't fit shock because perfusion is good. Pale skin that’s warm with a slow pulse isn’t typical of the sympathetic surge seen in shock. Bright pink mucous membranes with high blood pressure also doesn’t match shock, which usually features lower blood pressure as perfusion fails.
