,Q1. In a patient with chronic kidney disease not yet on dialysis, which dietary
modification is most likely to slow the decline of glomerular filtration rate?
A. Increasing dietary protein to 1.2 g/kg/day to prevent malnutrition
B. Restricting dietary protein to 0.6-0.8 g/kg/day with adequate energy intake
C. Supplementing with high-dose vitamin C to reduce oxidative stress
D. Encouraging a high-potassium diet to prevent hypokalemia
Correct Answer: B. Restricting dietary protein to 0.6-0.8 g/kg/day with adequate
energy intake
Rationale: In non-dialysis CKD, moderate protein restriction (0.6-0.8 g/kg/day) with
sufficient calories reduces uremic toxin production and may slow GFR decline, while
preventing protein-energy wasting. High protein intake increases glomerular
hyperfiltration and intraglomerular pressure, accelerating kidney damage. High-dose
vitamin C can cause oxalate accumulation, and high potassium is dangerous in CKD due
to impaired excretion.
Why Wrong:
A - High protein intake exacerbates glomerular hyperfiltration and accelerates renal
function decline.
C - High-dose vitamin C may lead to oxalate nephropathy and is not recommended in
CKD.
D - High potassium intake is contraindicated in CKD due to risk of hyperkalemia.

in CKD, 2020.
Q2. A patient with type 2 diabetes on metformin and insulin glargine presents with
morning hyperglycemia and nocturnal hypoglycemia. Which adjustment is most
appropriate to address this pattern?
A. Increase the evening insulin glargine dose to lower morning glucose
B. Decrease the evening insulin glargine dose and add a bedtime snack
C. Switch from insulin glargine to NPH insulin at bedtime
D. Add a rapid-acting insulin at bedtime to prevent morning hyperglycemia
Correct Answer: B. Decrease the evening insulin glargine dose and add a bedtime
snack
Rationale: Morning hyperglycemia with nocturnal hypoglycemia suggests the Somogyi
effect (rebound hyperglycemia) or overbasalization. Reducing the basal insulin dose and
providing a bedtime snack with complex carbohydrate and protein can stabilize nocturnal
glucose. Increasing the dose would worsen hypoglycemia; NPH has a peak that could
increase nocturnal risk; rapid-acting insulin at bedtime would further lower glucose.
Why Wrong:
A - Increasing basal insulin would exacerbate nocturnal hypoglycemia and potentially
Page 3
, worsen rebound hyperglycemia.
C - NPH insulin has a peak in the early morning, increasing the risk of nocturnal
hypoglycemia.
D - Rapid-acting insulin at bedtime would further lower glucose and increase
hypoglycemia risk.

Q3. Which of the following laboratory findings is most consistent with refeeding
syndrome in a patient receiving aggressive nutritional support after prolonged
starvation?
A. Hyperphosphatemia, hyperkalemia, and hypermagnesemia
B. Hypophosphatemia, hypokalemia, and hypomagnesemia
C. Hypernatremia, hypochloremia, and hypercalcemia
D. Hypoglycemia, hypertriglyceridemia, and elevated BUN
Correct Answer: B. Hypophosphatemia, hypokalemia, and hypomagnesemia
Rationale: Refeeding syndrome is characterized by severe electrolyte shifts, particularly
hypophosphatemia, hypokalemia, and hypomagnesemia, due to insulin surge driving these
ions into cells during anabolic metabolism. Hyperphosphatemia and hyperkalemia are not
typical; they may occur in renal failure. The other options describe different metabolic
derangements not specific to refeeding.
Why Wrong:
A - Refeeding syndrome causes intracellular shifts leading to low, not high, serum
phosphate, potassium, and magnesium.
C - Sodium and calcium imbalances are not the hallmark of refeeding syndrome.
D - Hypoglycemia may occur but hypertriglyceridemia and elevated BUN are not
primary diagnostic features.

to prevent and treat it. BMJ. 2008;336(7659):1495-1498.
Q4. A patient with short bowel syndrome is started on parenteral nutrition. Which
micronutrient deficiency is most likely to manifest if the intravenous formulation
lacks this element for an extended period?
A. Iron deficiency
B. Selenium deficiency
C. Vitamin K deficiency
D. Biotin deficiency
Correct Answer: B. Selenium deficiency
