the following minerals is necessary for the transmission of nerve impulses?
A) Phosphorus
B) Calcium

function and wound healing.
Question 3

A) Vitamin B-complex
B) Vitamin C
C) Vitamin D
D) All of the above
Rationale: Fat-soluble vitamins include vitamins A, D, E, and K (ADEK). These vitamins

A) Edema
B) Hypertension
C) Hyperglycemia
D) Tachycardia
