The nurse is assessing an elderly client's blood pressure during a routine visit. When asked, the client volunteers that when he took his pressure at home yesterday it was 126/72 mm Hg.
 
  The nurse determines that the client's pressure today is 134/70 mm Hg. The nurse recognizes that the most likely cause of the elevation is:
  1. The difference between the monitoring equipment being used
  2. The client may be experiencing mild anxiety regarding the check-up
  3. The effects of aging on the client's ability to hear the first Korotkoff sound
  4. The client is not inflating the cuff sufficiently to detect the systolic pressure
