Chapter 30 Question 1 The nurse notices that a patient in the intensive care unit has lost muscle mass and tone in his arms and legs. The nurse would attribute this loss to changes in which process? 1. Energy 2. Catabolism 3. Adenosine triphosphate 4. Anabolism Question 2 A patient who is being mechanically ventilated is demonstrating respiratory acidosis. The nurse suspects that which metabolic process is malfunctioning? 1. Anaerobic metabolism 2. Catabolism 3. Aerobic metabolism 4. Anabolism Question 3 A patient’s blood oxygen level is measured to be 78%. The nurse implements interventions to improve this level to avoid development of which situation? 1. Anabolism 2. Catabolism 3. Anaerobic metabolism 4. Aerobic metabolism Question 4 It has been calculated that a patient in the intensive care unit needs 1800 calories each day to sustain normal metabolic functioning. The nurse calculates that which number of calories is needed to sustain central nervous system functioning? 1. 1440 calories 2. 360 calories 3. 900 calories 4. 720 calories Question 5 A patient in the intensive care unit is surprised to learn that he has an elevated blood glucose level since he has not been diagnosed with diabetes. How should the nurse explain this elevation? 1. Many people are not diagnosed with diabetes until they are admitted to an intensive care unit. 2. Increasing blood glucose is the body’s way of making sure there is enough energy for brain functioning. 3. Many people have diabetes but are not aware of it. 4. When stressed, the body releases more glucose into the blood, raising the blood glucose level. Question 6 A patient is admitted with poor wound healing and malnutrition. To best address issues of wound healing the nurse designs interventions to support intake of which nutrient? 1. Protein 2. Minerals 3. Carbohydrates 4. Lipids Question 7 A patient with poorly controlled diabetes has elevated lipid levels in spite of her attempts to decrease fat and carbohydrate intake. How should the nurse explain this finding? 1. “You are not eating enough and your proteins are breaking down.†2. “Your body is using your high glucose levels to produce lipids.†3. “You are not eating enough carbohydrates.†4. “Most persons with diabetes are not able to efficiently metabolize fats.†Question 8 A male patient is 6 feet 2 inches tall with a body weight of 145 lbs. The nurse would calculate this patient’s BMI to be in which category? 1. Underweight 2. Normal 3. Overweight 4. Obese Question 9 A patient has been in the intensive care unit for 10 days after a traumatic injury requiring intubation and multiple blood transfusions. The patient now has assessment findings consistent with protein malnutrition. Which laboratory result would the nurse evaluate as supporting this diagnosis? 1. Prealbumin level 15 mg/dL 2. Transferrin level 325 mcg/dL 3. BUN level 10 mg/dL 4. Albumin level 4.0 g/dL Question 10 The nurse is explaining the mechanics of collecting a 24 hour urine urea nitrogen test to the patient. The nurse would also explain which purpose of this test? 1. Fluid status 2. Kidney function 3. Blood volume 4. Nitrogen balance
