Weak pedal pulses
Correct Answer : A,C,D,E
Smoking, Diabetes, Atherosclerosis, and Weak pedal pulses.
Factors that contribute to poor circulation to the limb include:
- Smoking: It can cause constriction and damage to the blood vessels, leading to poor circulation.
- Diabetes: High blood sugar levels can damage blood vessels and nerves, leading to poor circulation.
- Atherosclerosis: This is a condition where plaque builds up in the arteries, narrowing them and reducing blood flow.
- Weak pedal pulses: This can be a sign of reduced blood flow to the lower extremities. A sodium-restricted diet (Choice B) is not typically associated with poor circulation.
