Which mnemonic is used to remember the signs of arterial insufficiency?

• A. Pain, Pallor, Paresthesia, Paralysis, Pulselessness, and Poikilothermia
• B. Paresthesia, Pallor, Pruritus, Pulmonary edema
• C. Pain, Paresthesia, Pallor, Paralysis, Pulselessness
• D. Pain, Pallor, Paresthesia, Paralysis, Pulselessness, and Poikilothermia

Answer: (A)

The main idea being tested is the set of signs used to recognize arterial insufficiency, captured by the six Ps mnemonic. In acute limb ischemia, loss of arterial blood flow causes a cascade of symptoms: Pain from tissue ischemia, Pallor as the limb becomes pale, Paresthesia from nerve ischemia, Paralysis as ischemia progresses to motor nerves, Pulselessness due to absent distal arterial flow, and Poikilothermia, meaning the affected limb is cool to the touch and matches the room temperature. This combination of signs helps clinicians rapidly identify urgency. The best answer is the one that lists all six signs together, since that full set accurately reflects the mnemonic used to remember arterial insufficiency. Options that omit one of these signs or replace it with unrelated symptoms (like pruritus or pulmonary edema) don’t fit the characteristic pattern of arterial ischemia. Keep in mind that the presence of these signs, especially pulselessness and pallor with pain, signals a high-risk situation requiring prompt evaluation and intervention.
