The nurse should know that checking the blood pressure of a client who is obese using a standard-sized blood pressure cuff will result in which of the following?

Choice A reason: While technique can influence readings, the size of the cuff has a direct and predictable effect. Technique alone does not explain the consistent error caused by using a cuff that is too small. Choice B reason: Blood pressure readings are not the same regardless of cuff size. Using the wrong cuff size introduces systematic error. Choice C reason: Using a standard-sized cuff on an obese client results in a falsely high reading. The cuff is too small to compress the larger arm circumference properly, leading to overestimation of blood pressure. Choice D reason: A falsely low reading occurs when the cuff is too large, not too small. In obese clients, the problem is the cuff being too small, which causes falsely high readings.
