Cardiac Nursing
Cardiac nursing focuses on the assessment and management of patients with cardiovascular disorders including coronary artery disease, heart failure, dysrhythmias, valvular disease, and peripheral vascular conditions. NCLEX questions test your ability to interpret cardiac rhythms, recognize signs of cardiac emergencies, manage medications, and educate patients about lifestyle modifications and disease management.

Study Tips
- ✓Learn the difference between left-sided heart failure (pulmonary symptoms: dyspnea, crackles, orthopnea) and right-sided heart failure (systemic symptoms: edema, JVD, hepatomegaly).
- ✓Master the basic cardiac rhythms: normal sinus, atrial fibrillation, ventricular tachycardia, ventricular fibrillation, and asystole.
- ✓Create a drug card for each major cardiac medication class including ACE inhibitors, beta-blockers, calcium channel blockers, and anticoagulants.
- ✓Know the classic signs of myocardial infarction and how they may present differently in women, elderly patients, and diabetic patients.
- ✓Study cardiac catheterization care: pre-procedure consent and allergy assessment, post-procedure neurovascular checks and groin site monitoring.
Common Mistakes to Avoid
Students commonly confuse left-sided and right-sided heart failure symptoms, which leads to incorrect assessment conclusions. Another frequent error is failing to recognize atypical MI presentations in women and elderly patients, who may present with fatigue, nausea, or jaw pain rather than classic crushing chest pain. Students also confuse arterial and venous peripheral vascular disease: arterial disease causes pallor, pain with elevation, and absent pulses, while venous disease causes edema, brown discoloration, and stasis ulcers around the ankles.
Cardiac Nursing FAQs
Common questions about cardiac nursing
Left-sided heart failure causes blood to back up into the lungs, producing pulmonary symptoms: dyspnea, orthopnea, paroxysmal nocturnal dyspnea, crackles on auscultation, pink frothy sputum, and decreased oxygen saturation. Right-sided heart failure causes blood to back up into systemic circulation, producing peripheral edema, jugular vein distention (JVD), hepatomegaly, ascites, and weight gain. Remember that left-sided failure often leads to right-sided failure over time because pulmonary congestion increases right ventricular workload.
Key cardiac medications include: ACE inhibitors (-pril suffix; monitor for cough, hyperkalemia, angioedema), beta-blockers (-olol suffix; hold for HR <60, monitor for hypotension), calcium channel blockers (monitor for peripheral edema and constipation with verapamil), digoxin (therapeutic level 0.5-2.0 ng/mL, hold for HR <60, check potassium), nitroglycerin (up to 3 doses 5 minutes apart, monitor blood pressure), and anticoagulants (warfarin target INR 2-3, heparin monitor PTT). Always teach patients not to stop cardiac medications abruptly.
The classic mnemonic is MONA: Morphine (for pain unrelieved by nitroglycerin), Oxygen (if SpO2 is below 94%), Nitroglycerin (sublingual, up to 3 doses 5 minutes apart, hold if systolic BP is below 90), and Aspirin (chewable 325 mg unless contraindicated). The nurse should also place the patient in a semi-Fowler's position, obtain a 12-lead ECG within 10 minutes, establish IV access, initiate continuous cardiac monitoring, draw troponin and other cardiac markers, and remain with the patient. On the NCLEX, assessment (12-lead ECG) and immediate interventions (oxygen, aspirin, nitroglycerin) take priority over notifying the provider.
