This comprehensive document includes 85 expertly verified exam questions and answers for NURS 5315: Advanced Pathophysiology, focusing on the Cardiovascular System (Part I) for the academic year 2025/2026. It is a high-quality study guide that covers in-depth cardiovascular concepts essential for advanced nursing practice and clinical decision-making. Key topics include detailed anatomy and physiology of the heart, cardiac cycle, preload and afterload dynamics, stroke volume, ejection fraction, and mean arterial pressure (MAP). The document explores the electrophysiology of cardiac conduction, action potentials in myocytes and pacemaker cells, and interpretation of ECG components such as P waves, QRS complexes, and ST segments. It also outlines the effects of catecholamines, beta-blockers, calcium channel blockers, and other medications on cardiac function. Advanced clinical conditions are extensively discussed, including heart failure with reduced or preserved ejection fraction (HFrEF, HFpEF), valvular heart diseases (aortic/mitral stenosis and regurgitation), endocarditis, myocardial infarction (STEMI/NSTEMI), and angina (stable, unstable, Prinzmetal). Students will also gain a strong understanding of vascular physiology, hypertension, atherosclerosis, and dyslipidemia, supported by diagnostic lab markers like BNP, Troponin, CRP, and EKG findings. Who is this document for? This document is ideal for students in: – Advanced Practice Nursing (APRN) programs – Nurse Practitioner specializations (FNP, AGACNP, PMHNP) – BSN, RN-to-BSN, and MSN programs – Doctor of Nursing Practice (DNP) coursework – Courses in advanced pathophysiology, cardiology, and internal medicine Whether preparing for high-stakes exams, clinical rotations, or board certification, this resource provides a clear and comprehensive review of cardiovascular pathophysiology tailored for nursing students and practitioners. Keywords: NURS 5315, cardiovascular system, cardiac output, stroke volume, ejection fraction, preload, afterload, ECG, P wave, QRS complex, ST segment, heart failure, HFrEF, HFpEF, myocardial infarction, STEMI, NSTEMI, angina, mitral stenosis, aortic regurgitation, valvular disease, endocarditis, hypertension, dyslipidemia, atherosclerosis, catecholamines, troponin, BNP, advanced pathophysiology

Verified | Ace the Test



How does blood flow through the chambers of the heart? - 🧠 ANSWER

✔✔a) RA


b) Trucuspid

c) RV

d) Pulmonary arteries (semilunar)

e) Pulmonary veins

f) LA

g) Mitral

h) LV

,i) Aorta (semilunar)


Full contraction and relaxation is one ____. - 🧠 ANSWER ✔✔Cardiac Cycle


During diastole what part of the heart fills with blood? - 🧠 ANSWER

✔✔Ventricles


What occurs during systole? - 🧠 ANSWER ✔✔Ventricular contraction

pushes the blood from he right ventricle to the pulmonary artery and from

the left ventricle into the aorta

During atrial kick the pressure from the left atrial contraction make it

possible for what part of the body to fill with blood? - 🧠 ANSWER ✔✔Left

ventricle

Which side of the heart has higher pressures and which side of the heart

has lower pressures? - 🧠 ANSWER ✔✔Right side has lower pressures


Left side has higher pressures (pumps oxygenated blood to the rest of the

body)

Right ventricle systolic pressure is the pressure at the peak of systole, what

is the numeric range? - 🧠 ANSWER ✔✔15-28mmHg (pushing blood to

through pulmonary trunk and artery)

, Right ventricle end diastolic pressure is the pressure at the end of the

diastole, right before systole, what is the numeric range of pressure? - 🧠

ANSWER ✔✔0-8mmHg (low because ventricles fill with blood and are

relaxing)

Left ventricle systolic pressure is the pressure at the peak of systole, what

is the numeric range of this pressure? - 🧠 ANSWER ✔✔90-140 mmHg

(High because it's pushing blood through the aorta to the rest of the body)

Left ventricular end diastolic pressure us the pressure at the end of

diastole, right before systole, what is the numeric range of this pressure? -

🧠 ANSWER ✔✔4-12mmHg (Low because left ventricles are relaxing filling

with blood from the left atria)

What is the name of the amount of blood pushed from the left ventricle in 1

minute? - 🧠 ANSWER ✔✔Cardiac Output


What is considered normal cardiac output? - 🧠 ANSWER ✔✔5L/min


A decrease in heart rate and a decrease is stroke volume will have what

effect on Cardiac Output (CO)? - 🧠 ANSWER ✔✔Decreased cardiac output


The amount of blood ejected by the ventricle to the body for each cardiac

cycle (heart beat) is called? - 🧠 ANSWER ✔✔Stroke volume
