- A. It is a common peripheral vasodilator effect
- B. It shows severe kidney failure from the drug
- C. It indicates an immediate allergic reaction

Explanation
Amlodipine relaxes arteriolar smooth muscle and may cause peripheral ankle oedema because of increased capillary fluid movement. The nurse should assess the severity and report worsening swelling, but isolated mild ankle oedema is not usually an emergency allergic reaction.
