ANSWERS | A+ GRADED | WITH
EXPERT SOLUTIONS
Chest Pain AKA Angina Patho - correct answer -Patho: Chest
pain associated with decreased blood flow or ischemia to the
myocardial tissue.
Chest pain PA - correct answer -Physical Assessment: chest
heaviness
Pressure
Squeezing
Fullness
Pain radiates to left shoulder, arm, or jaw.
Elevation of blood pressure during attack
Chest pain Pharm - correct answer -Pharm: Nitroglycerin- relaxes
and widens blood vessels
Dosing: 0.3-0.6mg every 5 minutes for max of 3 doses
Long-term treatment to consider: ACE Inhibitors & Beta-Blockers
, Page | 2
Chest pain risks - correct answer -Risks and complications: Acute
Coronary Syndrome
Myocardial Infarction - correct answer -blood flow to the heart is
minimized.
Buildup of cholesterol
MI Patho - correct answer -imbalance between myocardial
oxygen supply and demand
Prolonged for greater than 30 minutes can lead to cardiac tissue
death.
MI PA - correct answer -Pain at rest
Not relieved with nitro
Lightheaded
Impending doom
Nausea
Diaphoresis
Wheezing
, Page | 3
MI Dx - correct answer -Troponins elevated, often stay elevated
for one week after infarction.
EKG- ST elevation or new left bundle branch block
Atherosclerosis - correct answer -when blood vessels that carry
oxygen to organs and tissues is restricted.
Hardening of vessels from buildup of fats, cholesterol in the artery
walls
Happens gradually.
Formed plaque can break off and burst, triggering a blood clot.
Atherosclerosis patho - correct answer -inflammatory process that
begins with damage to the endothelium often result of HTN,
smoking, high cholesterol, or other risk factors.
Fatty streak to fibrous plaque and then complicated lesion
Atherosclerosis PA - correct answer -modifiable risk factors
Fluid retention
Fatigue
Neck vein distension
, Page | 4
Edema
Calf pain
Atherosclerosis Dx - correct answer -Dx: Stress tests
Chest Xray
EKG
Ankle-Brachial Index to assess blood pressure in the extremities.
Atherosclerosis Pharm - correct answer -Pharm: Antiplatelets
(Aspirin)
Statins- reduce inflammation.
ACE Inhibitor- relax blood pressure and reduce work and
pressure on heart.
Can be treated with lifestyle management.
Heart Failure - correct answer -complex clinical syndrome that
results from structural or functional impairment of ventricular or
ejection of blood, which in turn leads to the cardinal clinical
symptoms of dyspnea and fatigue, edema, and rales.
