A client is 54 and weighs 250 pounds. When the client first came to the clinic 2 years ago, she weighed 347 pounds.
 
  A dietitian put her on a 1500-calorie per-day diet and a physician at the clinic prescribed fenfluramine and phentermine, the fen-phen drugs. Since then, fenfluramine has been taken off the market because it caused pulmonary hypertension in a number of individuals. The client says to a nurse, I don't know what to do I know I can't lose weight without those drugs. The nurse tells the client that she will lose weight, even without medication, if she just sticks to her diet and adds some exercise to her routine. What kind of exercise should the nurse suggest to this client?
  A) Low-impact aerobics three times a week
  B) Jogging 1 mile twice a week
  C) Swimming at the YWCA 30 minutes per day
  D) Walking around her neighborhood for 20 minutes per day (weather permitting)
