Answer to Question 1

Correct Answer: 1
Rationale 1: Vitamin C increases the absorption of iron when the two are taken concurrently.
Rationale 2: Vitamin C might only reduce the severity and duration of the common cold.
Rationale 3: Unlike most mammals, humans are unable to synthesize ascorbic acid.
Rationale 4: Large doses of vitamin C should be taken in divided amounts because the body only uses what is needed and the rest is excreted.
Global Rationale: Iron can be supplemented using various pharmacologic preparations, which often have ascorbic acid added to improve the absorption of PO iron. Vitamin C might only reduce the severity and duration of the common cold. Unlike most mammals, humans are unable to synthesize ascorbic acid. Large doses of vitamin C should be taken in divided amounts because the body only uses what is needed and the rest is excreted.

Answer to Question 2

Correct Answer: 4
Rationale 1: Ascorbic acid is not an appropriate treatment for insomnia.
Rationale 2: No evidence exists that vitamin C is a remedy for thinning hair or baldness.
Rationale 3: Postmenopausal women are not required to take more than normal doses of vitamin C.
Rationale 4: Vitamin C helps maintain the functions of the immune system for improved wound healing.
Global Rationale: Vitamin C is essential for the synthesis and maintenance of collagen and intercellular ground substance of body tissues, blood vessels, cartilage, bones, teeth, skin, and tendons. It is not used for insomnia, thinning hair, or baldness. There is no indication that postmenopausal women should take additional vitamin C.
