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 of the following number of calories are needed to sustain central nervous system functioning? 1. 1440 calories
2. 720 calories
3. 900 calories
4. 360 calories
4
Rationale: About 40% of energy needed by the body is used to maintain ion gradients across cell membranes. Synthesis of proteins and central nervous system functions each require about 20 percent of the energy expenditure. Other essential functions such as oxidation of nutrients, breathing, and cardiac pumping consume the rest of the energy expenditure. The patient's daily needs are 1800 calories. Twenty percent of this number of calories is 360 calories. The other choices are incorrect.
