1.1 Cardiac Anatomy & Physiology — Quick Reference
❤ Heart Chambers
Right Atrium → receives deoxygenated blood from body. Right Ventricle → pumps to lungs
Left Atrium → receives oxygenated blood. Left Ventricle → pumps to body (strongest chamber)
Blood Flow Pathway (NCLEX Favorite!)
RA → RV → Pulmonary Artery → Lungs → Pulmonary Vein → LA → LV → Aorta → Body
⚡Electrical Conduction
SA Node → AV Node → Bundle of His → Bundle Branches → Purkinje Fibers
, Basic Hemodynamic Facts
1. Preload = volume 2. Afterload = resistance 3. Contractility = squeeze
4. Cardiac Output = HR × Stroke Volume (normal 4–8 L/min)
High-Yield Cardiac Drugs
ACE inhibitors = cough, hyperkalemia, low BP. Beta-blockers = “brady + low BP + bronchospasm”
Digoxin = toxicity risk ↑ with low K+ . Diuretics = watch K+ and dehydration
1.2. Cardiac Anatomy & Physiology – (Q1–50)
1. A client with left-sided heart failure is most likely to exhibit which symptom?
A. Peripheral edema
B. Jugular vein distention
C. Crackles in the lungs
D. Hepatomegaly
✅Correct Answer: C. Crackles in the lungs
Rationale: Left-sided heart failure causes pulmonary congestion and edema, leading to crackles
on auscultation. Peripheral edema and hepatomegaly are more characteristic of right-sided HF.
2. A client receiving digoxin has a potassium level of 2.9 mEq/L. The nurse should:
A. Give digoxin
B. Hold digoxin
C. Give IV magnesium
D. Increase fluid intake
✅Correct Answer: B. Hold digoxin
Rationale: Hypokalemia increases the risk of digoxin toxicity. The drug should be held, and the
provider notified.
3. Which ECG finding is most associated with hypokalemia?
A. Tall peaked T waves
B. U waves
C. Prolonged QT
D. ST elevation
✅Correct Answer: B. U waves
Rationale: Hypokalemia causes U waves, flattened T waves, and ST depression, which are
