Question 1

A client presents with fatigue, pale conjunctiva, and a mean corpuscular volume (MCV) of 72 fL. Which nutrient deficiency is most likely responsible?

Accepted Answer

Iron

Answer

Iron deficiency causes microcytic anemia characterized by low MCV, reflecting impaired hemoglobin synthesis.

Question 2

Which of the following is the primary function of carnitine in cellular metabolism?

Accepted Answer

Transporting long-chain fatty acids into the mitochondria

Answer

Carnitine shuttles long-chain fatty acids across the inner mitochondrial membrane so they can undergo beta-oxidation.

Question 3

A clinical nutritionist is designing a meal plan for a patient with end-stage renal disease on hemodialysis. Which nutrient restriction is typically LESS stringent for dialysis patients compared to pre-dialysis patients?

Accepted Answer

Protein

Answer

Hemodialysis patients actually require higher protein intake (1.2–1.4 g/kg/day) due to dialysis-related losses, unlike pre-dialysis patients who restrict protein.

Question 4

Which vitamin acts as a coenzyme in transamination reactions and is critical for amino acid metabolism?

Accepted Answer

Vitamin B6 (pyridoxine)

Answer

Pyridoxal phosphate, the active form of vitamin B6, is the essential coenzyme in all transamination reactions.
