Exam Cram NCLEX RN Practice Questions - Nurselytic

Correct Answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important.
Choice A is incorrect as providing a vague reassurance does not address the patient's query.
Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect.
Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.
