ASPEN 3rd Edition Test Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) Which of the following is the largest component of total energy expenditure (TEE)?

A. RMR

• Thermic effect of digestion
• Physical Activity
• Metabolic Stress - Correct Answers ✅*A. RMR*

The thermogenic effect of digestion is generally thought to contribute to no more than 10% to TEE. Activity contributes to 5% - 30% to TEE. With the exceptions of burn and sepsis, metabolic stress contributes to less than 50% TEE. However, in almost all situations, RMR constitutes 60% to 75% of TEE.Which of the following is the most commonly used method for assessing energy expenditure?

• Indirect calorimetry (IC)
• Predictive equations
• The reverse Fick equation
• Doubly labeled water - Correct Answers ✅*B. Predictive

Equations* Most nutrition support feeding regiments are based on predictive equations used to assess energy expenditure. The measurement of energy expenditure via IC is more accurate than predictive equations but is underused because the 1 / 4

ASPEN 3rd Edition Test Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) equipment is expensive to purchase and operate, and because some patients cannot be measured for various technical and physiological reasons.Which parameter is measured when using IC?

• Heat loss
• Catabolic rate
• Gas exchange
• Free energy balance - Correct Answers ✅*C. Gas

exchange* Indirect calorimeters measure respiratory gas exchange (the difference between inspired and expired oxygen and carbon dioxide). If proper testing conditions are observed, respiratory gas exchange is equivalent to metabolic gas exchange (the consumption of oxygen and production of carbon dioxide at the cellular level). Gas exchange data are converted to RMR using the Weir equation.You are determining the energy intake target for a 53-year- old, critically ill, male patient who is about to start enteral feeding. He is 170 cm in height and weighs 150 kg. His body mass index is 51.9 and his ideal body weight is 70 kg. Body temperature is 37.3 degrees Celsius and minute ventilation is 12.5 L/min. Based on the 2016 ASPEN guideline for calculating a goal energy intake for such a critically ill patient, 2 / 4

ASPEN 3rd Edition Test Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) what energy value would you use as the basis for the feeding plan?

• 1750 kcal/d (25 kcal per kg ideal body weight)
• 1225 kcal/d (70% of the calculated 25 kcal per kg ideal

body weight)

• 2250 kcal/d (25 kcal per kg adjusted body weight)
• 2615 kcal/d (Penn State Equation) - Correct Answers

✅*A. 1750 kcal/d (25 kcal per kg ideal body weight)* The ASPEN guideline states that the goal intake for all classes of obesity should not exceed 65% to 70% of target energy expenditure as measured by IC. For class III obesity, an intake of 22 to 25 kcal per kg ideal body weight is recommended.The Penn State equation has been validated as being among the most accurate ways of calculating energy expenditure up to a BMI of at least 80. However, answer D is incorrect if following the ASPEN guideline because that guideline emphasizes the kcal/kg method. The patient has class III obesity; therefore, ideal body weight would be used for the calculation, making answer C incorrect because it uses adjusted body weight. Answer B is incorrect because the guideline already factors the 30% reduction of the energy calculation into the standard; therefore, if energy expenditure were calculated and then multiplied by 70%, the effect would be to reduce the energy intake to about 50% of expenditure. 3 / 4

ASPEN 3rd Edition Test Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) Which of the following practices is most likely to succeed in improving oral nutrient intake in patients with a prolonged history of weight loss due to poor intake, nausea, and depressed appetite?

• Providing a high-energy oral liquid supplement 3 times

daily

• Offering 6 small, low-fat meals daily
• Ordering fiber-supplemented snacks 3 times daily
• Planning primarily solid meals and limiting fluids - Correct

Answers ✅*B. Offering 6 small, low-fat meals daily* When patients experience a prolonged negative energy balance, the stomach's adaptive accommodation function declines; therefore, patients may not be able to consume their goal nutrient targets in 3 regular-sized meals because of a feeding of fullness. Eating 6 small meals may be a more realistic option. To address nausea, measures should be taken to prevent slowing of gastric emptying, which could potentiate nausea. These measures may include limiting high-fat foods. Providing high-energy or high-fiber supplements initially may not be the best recommendation because, like fat, energy density and fiber content can slow gastric emptying. Answer D is not a good choice because providing fluids, not limiting them, facilitates gastric emptying.
