Diagnostics & Anatomy
This specific layer of the cardiac wall contains the thick, specialized muscle tissue responsible for the heart's forceful pumping mechanism.
What is the myocardium?
Rheumatic fever and subsequent rheumatic carditis most commonly manifest as an inflammatory complication following an infection caused by this microorganism.
What is Group A streptococcus?
This condition is defined as the age-related loss of arterial wall elasticity and hardening, distinguishing it from plaque accumulation.
What is arteriosclerosis?
This form of high blood pressure accounts for the vast majority of cases and is defined as having no known or identifiable underlying medical cause.
What is essential (primary) hypertension?
A patient using sublingual nitroglycerin at home for angina should be taught to take a second tablet and immediately call 911 if their chest pain is not relieved after this timeframe.
What is 5 minutes?
This primary pacemaker node initiates a normal heart rhythm at an expected rate of 60 to 100 beats per minute.
What is the sinoatrial (SA) node?
Auscultating a distinct pericardial friction rub at the lower left sternal border is a hallmark clinical indicator of this specific condition.
What is acute pericarditis?
This vascular condition involves the narrowing and occlusion of the arterial lumen specifically by fatty cholesterol deposits called plaque.
What is atherosclerosis?
The primary medical goal when treating a patient experiencing a severe hypertensive crisis is to safely lower the blood pressure within 1 to 3 hours using IV drugs to protect these.
What are target organs (such as kidneys, brain, and heart)?
Before administering a schedule dose of digitalis (Lanoxin) to a heart failure client, the nurse must complete this mandatory safety action.
What is counting the apical pulse for a full minute to ensure it is not below 60 bpm?
Before a client undergoes a cardiac cauterization, checking for allergies to these two specific substances is a priority nursing action.
What are iodine and contrast dye?
To prevent bacteria from traveling through the bloodstream and adhering to vulnerable valves, high-risk patients must receive this intervention before invasive dental work.
What is prophylactic antibiotic therapy?
This highly specific laboratory biomarker is measured in the blood to definitively confirm necrotic myocardial tissue damage following an acute MI.
What is Troponin?
This specific type of exercise program is highly recommended for hypertensive clients to help safely control systemic arterial blood pressure.
What are isotonic (dynamic) exercises, such as walking or cycling?
This intravenous medication is classified as a cholinergic blocking agent and is administered as the first-line drug to treat a dangerously slow, symptomatic sinus bradycardia.
What is atropine sulfate?
To prevent a severe hemorrhage at the femoral artery puncture site following a cardiac cauterization, the nurse must instruct the patient to implement this restriction.
What is keeping the affected leg completely straight and avoiding movement?
In severe cases of aortic stenosis, the muscular wall of the left ventricle hypertrophies (enlarges) for this primary physiological reason.
What is to contract with enough force to push blood through the stiff, narrowed opening?
A client with Peripheral Artery Disease (PAD) who experiences severe lower-extremity cramping during activity that is entirely relieved by rest is experiencing this classic symptom.
What is intermittent claudication?
Left-sided heart failure causes a backup of fluid and congestion primarily within this area of the body.
What are the lungs (pulmonary system)?
During a convention open-heart Coronary Artery Bypass Graft (CABG) procedure, this blood vessel is most frequently harvested from the patient's leg to serve as the detour conduit.
What is the saphenous vein?
This diagnostic test requires the patient to keep a detailed written diary of their activities and matching physical symptoms while wearing a continuous recording device.
What is an Ambulatory ECG (Holter monitoring)?
To minimize palpitations and alleviate anxiety, a practical nurse should instruct a client diagnosed with mitral valve prolapse syndrome to eliminate these two substances from their diet.
What are caffeine and alcohol?
To manage the underlying inflammatory process Thromboangiitis Obliterans (Buerger disease), the nurse must instruct the client to completely eliminate this lifestyle factor.
What is tobacco smoking?
A nurse notes that a client with worsening right-sided heart failure is accumulating fluid. The nurse expects to find this cluster of assessment symptoms.
What are dependent pitting edema, jugular vein distention (JVD), and rapid weight gain?
To support an adequate cardiac output in a postoperative cardiovascular surgery patient with impaired ventricular contractions, the nurse prepares to administer this class of medications.
What are inotropic agents (to increase contractility) and antidysrhythmics (to support conduction)?
