NTP Nutrient Deficiencies & Imbalances 3

Question 1

Subperiosteal hemorrhages and perifollicular hemorrhages in an adult are hallmark signs of deficiency of which nutrient?

Accepted Answer

Vitamin C

Answer

Vitamin C (ascorbic acid) is required for collagen synthesis; its deficiency (scurvy) causes fragile blood vessels, leading to subperiosteal and perifollicular hemorrhages.

Question 2

A client taking high-dose supplemental zinc for an extended period is at risk for secondary deficiency of which mineral?

Accepted Answer

Copper

Answer

High zinc intake competitively inhibits copper absorption in the intestine via shared metallothionein binding, leading to copper deficiency.

Question 3

Night blindness as an early symptom of nutrient deficiency suggests which micronutrient is depleted?

Accepted Answer

Vitamin A

Answer

Vitamin A (retinol) is required to synthesize rhodopsin in rod photoreceptors; deficiency impairs dim-light vision, causing night blindness.

Question 4

A patient on long-term metformin therapy should be monitored for deficiency of which nutrient?

Accepted Answer

Vitamin B12

Answer

Metformin reduces vitamin B12 absorption by interfering with calcium-dependent intrinsic factor activity in the ileum, requiring monitoring and often supplementation.

Question 5

Which nutrient deficiency is most directly linked to Keshan disease, a form of cardiomyopathy?

Accepted Answer

Selenium

Answer

Keshan disease is an endemic cardiomyopathy linked to selenium deficiency, as selenium is essential for glutathione peroxidase, protecting cardiac tissue from oxidative damage.
