Intervention for a Critically Ill Patient
Ken Alden, a 36-year-old male, is in the hospital for treatment of severe burns following an industrial
fire. Ken was working near an area of a factory that exploded, and suffered second and third degree
burns over 40 percent of his body. Ken has been in the intensive care unit since his hospital admission
two days ago. He is on a ventilator to assist with his breathing and the physician has placed a central line
for administration of parenteral nutrition support. The nursing staff weighs Ken daily; his current weight
is 168 lbs. correct answers
1. The damaging effects of the burns have elicited the stress response in Ken's body, and his cortisol
levels have been elevated since the injury. Because Ken's recovery will be extensive, he is at increased
risk of what effects of prolonged elevated cortisol? correct answersb. Protein degradation
2. Estimate Ken's energy needs using the Ireton-Jones formula of: 1784 + [5 x Wt (kg)] - [11 x Age (yr)] +
[244 x Sex] + [239 x Trauma] + [804 x Burn]. correct answerse. 3056 kcal
3. Most of Ken's energy intakes come through carbohydrates and fats administered with his parenteral
nutrition. His carbohydrate intake provides 50 to 60 percent of his total energy requirements. To prevent
hyperglycemia, Ken's dextrose should be limited to no more than _____ mg/kg of body weight per day.
correct answersb. 5
4. After another 48 hours, Ken's physician decides to discontinue total parenteral nutrition and to change
to enteral feedings, administered via a feeding tube. Ken's gastrointestinal system was unaffected by his
injuries and it is functioning well. The clinician inserts an orogastric feeding tube to be used for enteral
feedings while Ken is on a ventilator. When compared with delayed feedings, early introduction of
enteral feedings has been shown to provide what benefit to hospital patients? correct answersa. Shorter
hospital stays
5. Ken received very large amounts of intravenous fluids after his hospital admission because he required
initial fluid resuscitation to prevent loss of intravascular fluid volume. The clinician is now having a
difficult time assessing Ken's nutritional needs. Fluid imbalances that occur among patients with critical
illnesses cause challenges in estimating nutrient needs in what manner? correct answersc. Fluid
imbalances prevent accurate weight measurement
