BSNC FINALS ACTUAL QUESTIONS AND
ANSWERS SURE A+
✔✔Central Perfusion - ✔✔- Generated by CO
- Propels blood to various organs and returns to heart
✔✔Tissue Perfusion - ✔✔- Vol. of blood that flows through target tissues
- Determined by central perfusion
✔✔Relationship between BP and perfusion - ✔✔High BP = Low Perfusion
Low BP = Low Perfusion
✔✔Pathophysiology of Hypertension: - ✔✔- When MAP is consistently elevated
- MAP = CO + TPR
- Hypertension = CO or TPR or both are consistently elevated
- BP elevated by hormonal or neurological control
✔✔Methods to assess perfusion - ✔✔- Interview
- Inspect
- Auscultate
- Palpale pulses
- Measure HR
- Measure BP, cap refill, height/weight
✔✔Blood Pressure Cuff Theory - ✔✔- Cuff stops arterial blood flow when inflated
- Korotkoff sounds are created by pulsing blood flow through compressed artery
- Blood flow is silent when artery isn't compressed
✔✔Factors that impact BP - ✔✔- Drugs
- Caffeine
- Exercise
- Time of Day
- White Coat Syndrome
