A Group of Novice Nursing Students Are Learning How to Manually

A group of novice nursing students are learning how to manually measure a client's blood pressure using a stethoscope and sphygmomanometer. Which of the following statements by students would the instructor most likely need to correct?

A) "I'll inflate the cuff around 30 mm Hg above the point at which I can't palpate the client's pulse."
B) "If my client's arm is too big for the cuff, I'm going to get a BP reading that's artificially low."
C) "The accuracy of the whole process depends on my ability to clearly hear the Korotkoff sounds with the bell of my stethoscope."
D) "With practice, my measurement of clients' blood pressures with this method will be more accurate than with automated machines."
