Check (Correct answer)
Do
Act
Plan

Correct answer: Check

The Check phase involves studying the results of the intervention by comparing data against the expected outcomes.

Question 3: Current evidence recommends which approach to protein intake in patients with liver cirrhosis and hepatic encephalopathy?

Maintain adequate protein; use branched-chain amino acids if standard protein is not tolerated (Correct answer)
Restrict only animal protein
Double normal protein intake
Eliminate protein completely

Correct answer: Maintain adequate protein; use branched-chain amino acids if standard protein is not tolerated

Protein restriction in cirrhosis is no longer recommended; adequate protein is essential, and BCAA supplementation may assist tolerance.

Question 4: In a clinical nutrition department, a newly implemented enteral feeding protocol is being evaluated. What does 'process measure' refer to in this context?

The number of patients discharged on tube feeding
The 30-day patient mortality rate
Whether the protocol steps are being followed correctly (Correct answer)
The cost savings achieved after implementation

Correct answer: Whether the protocol steps are being followed correctly

Process measures assess whether specific steps or actions in a protocol are being executed as intended, distinct from outcomes or structural measures.

Question 5: To reduce aspiration risk during continuous enteral feeding, the head of the bed should be elevated to at least:

0–15 degrees
30–45 degrees (Correct answer)
15–25 degrees
60–90 degrees

Correct answer: 30–45 degrees

Elevating the head of the bed to 30–45 degrees uses gravity to reduce gastric reflux and lower aspiration risk during enteral feeding.

Question 6: A dietitian discovers that a specific brand of infant formula has been mixed at the wrong concentration for two days in a neonatal ICU. This event should FIRST be reported as:

A routine process variance logged in the quality database
A corrective action plan for the responsible nurse
A sentinel event requiring immediate root cause analysis (Correct answer)
A near-miss that requires no immediate escalation

Correct answer: A sentinel event requiring immediate root cause analysis

Incorrect formula concentration in a neonatal ICU is a serious safety event that meets the threshold for a sentinel event, requiring immediate root cause analysis.

Question 35: Which supplement might a patient who has had their stomach removed need?

B12 (Correct answer)
Copper
Zinc
Vitamin B6

Correct answer: B12

The stomach produces intrinsic factor, a glycoprotein essential for the absorption of vitamin B12 in the small intestine. When the stomach is removed (gastrectomy), the production of intrinsic factor ceases. Without intrinsic factor, dietary vitamin B12 cannot be absorbed, leading to a deficiency. Therefore, patients who have undergone a gastrectomy typically require lifelong vitamin B12 supplementation, often via injection or high-dose oral supplements.

Question 36: A patient receiving continuous tube feeding via nasogastric tube has a gastric residual volume (GRV) of 550 mL. What is the most appropriate action?

Hold the feeding and notify the care team (Correct answer)
Continue feeding at the same rate
Increase the feeding rate to compensate
Switch to parenteral nutrition immediately

Correct answer: Hold the feeding and notify the care team

A GRV of 500 mL or greater is typically the threshold to hold enteral feedings and reassess, as it may indicate delayed gastric emptying and aspiration risk.

Question 37: What is the primary dietary modification recommended for patients with chronic kidney disease (CKD) stage 3-4?

Increase protein intake to 1.5 g/kg/day
Eliminate all carbohydrates
Increase sodium intake
Restrict potassium and phosphorus intake (Correct answer)
