MK 3 - CCB, Chest tubes, CHD, Infectious Diseases Questions and Correct Answers

Calcium Channel Blockers -CCBs are like "valium" for your heart --Valium calms you down. Therefore, CCB relaxes and slows down the heart ---If the heart is tachycardic, tachyarrhythmia, or heart attack → needs to be rested → GIVE CCB ---If you are in shock, or you are in heart block → needs to be stimulated → should NOT give CCB inotropic, chronotropic and dromotropic effects of CCBs -In other words, CCBs have negative inotropic, chronotropic, and dromotropic effects on the heart -Positive ino/chrono/dromotropic = cardiac stimulants = strengthen heartbeat -Negative ino/chrono/dromotropic = cardiac depressants = weaken/slow down / depress heart best = CCB What do CCB treat? "A, AA, AAA" -A: Antihypertensives - relaxes heart blood vessels (BV) ⇒ BP goes down -AA: AntiAnginal - relaxes heart, works by decreasing oxygen demand -AAA: AntiAtrialArythmia - treats atrial-flutter/ fibrillation, premature atrial contraction, atrial bigeminy, and SVT --SVT is included because "supraventricular" means above the ventricles which is really the atria Side effects of CCB "H-H" -Headache - vasodilation → migraine (for SATA questions, H/A is often correct) -Hypotension - as it relaxes blood vessels Examples of CCB -DIPINE, verapamil/isoptin, cardizem (diltiazem) -Diltiazem can be given with IV drip -Amlodipine Administration of CCBs Nurse should assess / monitor BP before giving CCB -If SBP is <100, hold the CCB -If SBP is <100 when diltiazem is given with drip, titrate the rate of the IV depending on how low the SBP is
