Question 1

A patient with chronic kidney disease (CKD) stage 4 presents with hyperkalemia. Which dietary intervention is the priority?

Accepted Answer

Limit potassium to 2000–3000 mg/day

Answer

Hyperkalemia in CKD requires potassium restriction, typically 2000–3000 mg/day, to prevent life-threatening cardiac arrhythmias.

Question 2

Which anthropometric measurement best reflects visceral adiposity and associated metabolic risk in adults?

Accepted Answer

Waist circumference

Answer

Waist circumference is the best anthropometric proxy for visceral adiposity and correlates most strongly with cardiometabolic risk.

Question 3

A registered dietitian reviews a patient's 24-hour recall showing a diet very high in oxalate-rich foods. This finding is most clinically significant for a patient with a history of:

Accepted Answer

Calcium oxalate kidney stones

Answer

High dietary oxalate increases urinary oxalate excretion, promoting calcium oxalate crystal formation and recurrent calcium oxalate nephrolithiasis.

Question 4

The Mifflin-St Jeor equation is used clinically to estimate:

Accepted Answer

Resting metabolic rate

Answer

The Mifflin-St Jeor equation estimates resting metabolic rate (RMR) using age, sex, height, and weight, and is considered the most accurate predictive equation in non-obese adults.

Question 5

A patient post-Roux-en-Y gastric bypass is at highest risk for deficiency in which nutrient due to bypass of the duodenum and proximal jejunum?

Accepted Answer

Iron

Answer

Iron is primarily absorbed in the duodenum and proximal jejunum, which are bypassed in Roux-en-Y gastric bypass, leading to high risk of iron-deficiency anemia.
