CSG CSG Enteral & Parenteral Nutrition Support 2

Question 1

A high gastric residual volume (GRV) during tube feeding typically indicates:

Accepted Answer

Delayed gastric emptying requiring feeding rate adjustment

Answer

Elevated GRV suggests delayed gastric emptying, which increases aspiration risk and warrants holding or reducing the feeding rate and assessing for prokinetic therapy.

Question 2

Which enteral formula type is MOST appropriate for an older adult with glucose intolerance or type 2 diabetes?

Accepted Answer

Diabetes-specific formula with modified carbohydrate content

Answer

Diabetes-specific enteral formulas contain lower glycemic index carbohydrates and higher fat content to reduce postprandial glucose excursions in older adults with diabetes.

Question 3

Parenteral nutrition is indicated in an older adult when:

Accepted Answer

The gastrointestinal tract is non-functional or inaccessible for more than 7 days

Answer

Parenteral nutrition is reserved for situations where the GI tract cannot be used safely or adequately for at least 5–7 days, such as bowel obstruction or severe malabsorption.

Question 4

Free water flushes via feeding tube are primarily used to:

Accepted Answer

Maintain hydration and prevent tube occlusion

Answer

Regular free water flushes (typically 30 mL before and after medications and every 4–6 hours during feeding) prevent tube occlusion and ensure adequate hydration in tube-fed patients.

Question 5

Which complication of long-term parenteral nutrition in older adults is related to liver function?

Accepted Answer

Parenteral nutrition-associated liver disease (PNALD)

Answer

Long-term PN can cause hepatic steatosis, cholestasis, and cirrhosis (PNALD) due to continuous glucose and lipid infusion without enteral stimulation of bile flow.
