QUESTIONS & ANSWERS | GRADE A | 100%
CORRECT (VERIFIED SOLUTIONS) –
CHAMBERLAIN
What is a beta blocker? - Medications used for CV treatment
Which class of anthyarrithmics are the B-blockers? - Class II
where are the receptors located? - B1- the heart
B2-the lungs
Example of B1 - Atenolol & Metroprolol
Example of B2 - Propanolol, carvedilol.
What is the function of the B-Blockers? - They respond to catecolaminas and activated the
SNC resulting in de crease of HR, vasodilatation, and enhaced metabolic activity.
These factors will help reduce the BP
Precautions for B-Blockers? - Can cause bronchoconstriction, careful with asthmatics.
Careful with diabetes, mask symptoms of low blood sugar.
Renal or hepatic dysfunction.
History of depression, uncompensated HF.
Side effects of B-Blockers? - Postural hypotension, bradycardia, drowsiness and depression
Selective beta blockers - Safe to use in pts with respiratory issues since they will bind only to
B1 located in the heart
Non selective B-blockers - Bind to B1 and B2 affects the lungs
not safe for pts with lung disorders since it cause bronchospasm
Uses of B-blockers? - Hypertension
HF
, Long term Angina
Arrhytmias
Migraine prophylaxis
What is calcium channel blocker (CCB) - A class of medications that interfere with calcium
ion movements. Blocks calcium access to the cells, causing decreased heart contractility and
conductivity and leading to decreased oxygen demand. Reduce AV node conduction. Inhibit slow
channel pathways
What class of antiarrhythmic are the CCB? - Class IV
Uses of CCB? - HTN, Angina, Arrhythmias (atrial flutter and a fib), pulmonary HTN
Which population are the CCBS first line of treatment? - African Americans
Name of Type I CCBs - Verapamil & Diltiazem
Name of Type II CCBs - Amlodipine, Nifedipine & Nicardipine
Side effects of CCB? - PEDAL EDEMA, hypotension, constipation, dizziness
CCBs such as verapamil and diltiazem are contraindicated for pts with...? - pt with 2nd and
3rd degree heart block
Contraindications of CCB? - GRAPEFRUIT JUICE ,Severe hypotension, HF, Bradycardia
Nurse interventions when administer CCB? - Monitor VS, education on side effects, asses for
signs of HF, promote adherence
What is systemic vascular resistance (SVR)? - Refers to the resistance that blood vessels offer
to blood flow.
Describe Afterload? - The pressure against which the heart must work to eject blood during
systole.
What does ACE inhibitors medications do? - Inhibit conversion of Angio 1 to 2.
Prevents vasoconstriction (decrease BP and SVR)
*Inhibits secretion of Aldosterone (excrete water and Na, keep K, monitor K levels)
Uses of ACE inhibitors? - HTN, HF
Example of ACE inhibitors? - Ends with "PRIL"
Captopril, Enalapril & Lisinopril
