1. The nurse practitioner for a cardiology practice is responsible for providing presurgical teaching for patients who are about to undergo a coronary artery bypass graft. Which of the following teaching points best conveys an aspect of the human circulatory system? (Points : 3)“Your blood pressure varies widely between arteries and veins, and between pulmonary and systemic circulation.”“Only around one quarter of your blood is in your heart at any given time.”“Blood pressure and blood volume roughly mimic one another at any given location in the circulatory system.”“Left-sided and right-sided pumping action at each beat of the heart must equal each other to ensure adequate blood distribution.”Question 2.2.

Which of the following assessment findings in a newly admitted 30-year-old male patient would be most likely to cause his nurse practitioner to suspect polyarteritis nodosa? (Points : 3)The mans blood work in
