The respiratory exchange ratio (rer) is a way of determining the body's metabolism of:

The respiratory   exchange ratio  (RER)   is  a  way  of   determining  the   body  metabolism  of  carbohydrate  and  fat.
   The   respiratory   exchange  ratio   is  the ratio  between  the  amount  of  carbon  dioxide  produced  and  oxygen  used. Measuring  this  ratio   can  be  used  to  estimate  the  respiratory  Quotient (RQ)  which  an  indicator  of  which  carbohydrate or  fat  is  being metabolized  to  supply  the   body  with    energy.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
