NEWEST 2025 ACTUAL EXAM COMPLETE 150 QUESTIONS
AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+
Receptors - ANSWER Norepinephrine-Adrenergic (adrenergic comes
from the word adrenalin)
Alpha 1-all sympathetic target organs except the heart-constrict the
blood vessels and dilation of pupils
Alpha 2-Presynaptic adrenergic nerve terminal-inhibits the release of
norepinephrine
Beta 1-Heart and Kidneys (BETA 1-ONE HEART)-increased heart rate
and force of contraction, release of renin
Beta 2-All sympathetic target organs-inhibits smooth muscle (BETA 2-
TWO LUNGS)
Beta blockers/olol's - ANSWER Beta-Adrenergic Blockers
Metoprolol/Lopressor ENDING OLOL
Beta Blockers are use with heart failure, hypertension, angina and with
myocardial infarctions.
Action = Blocks Beta-Receptors in the heart causing...
Decreases = HR, force of contraction, Rate of atrioventricular (AV)
conduction
SE = Bradycardia, lethargy, GI disturbance, congestive heart failure,
decrease BP, depression
, The beta blockers stop sympathetic nervous system stimulation of the
heart. Does not allow the heart rate and blood pressure to rise with stress
thus lowering the oxygen demand of the heart. It is very heart protective!
Will slow the heart rate and lower the blood pressure
Can have beta 2 blockage with larger doses-will constrict the
bronchioles-watch for clients with known COPD, Asthma
Nursing Interventions
Check pulse-needs to be 60 or above
Check blood pressure-if hypotensive do not give (Systolic below 100 is
a good rule of thumb I go by)
Monitor for sexual dysfunction-impotence for men-a good reason for
non-compliance
Drowsiness/Fatigue-operating heavy machinery, driving could put client
at risk
Insomnia-
Contraindicated with Heart Blocks, Bradycardia, Worsening Heart
Failure
Increases Hypoglycemic effect of Insulin-monitor blood sugars and for
hypoglycemia, may need to lower insulin dosage
Beta Blockers have to be weaned slowly to prevent rebound
hypertension and tachycardia-if a client wants to stop his beta-blocker
they need to contract their physician
CCB,/calcium channel blockers - ANSWER
Nifedipine/Adalat/Procardia/Norvasc-controls blood vessels
Diltiazem/Cardizem
Verapamil/Calan/Isoptin/Verelan-controls heart rate and blood vessels
Angina/Raynaud's/Vasospastic Angina/Atrial Arrhythmia's
Blocks calcium channels in the myocardial and vascular smooth
muscles, decreases the contraction of smooth muscle-relaxes the
arteries-vasodilation. Blocking of calcium channels in the SA and AV
,node-Slows conduction through the SA and AV node. Decreases the
force of contraction slows heart rate
Grapefruit juice may increase absorption of nifedipine
Side Effects: Relaxes smooth muscle and cardiac muscle-
Headache
Dizziness-Take lying, sitting and standing B/P, educate client to sit and
stand slowly
Peripheral edema-assess for edema, monitor for worsening (diuretic)
Flushing
Reflex tachycardia-monitor for elevated heart rate (may need a BB)
Constipation-increase fibers and fluids (if not restricted) stool softener
Fatigue-Due to low heart rate-monitor EKG, pulse rate and rhythm
Weakness-Monitor B/P and Heart Rate
Impotence and sexual dysfunction-Discuss possibility with client-have
client to call and not just to stop medications
Hepatotoxicity-ALT, AST, ALK PHOS, Bilirubin
MI-Monitor for chest pain, dyspnea, increases fatigue, weakness
CHF-Monitor for chest pain, dyspnea, edema, increasing weight,
decreasing output, increasing HR and B/P
Angioedema-edema in face, throat, trouble swallowing, trouble
breathing, thickened tongue
Grapefruit juice may increase absorption of nifedipine
Acute Toxicity
With an overdose or overmedicated
Gastric lavage
Monitor EKG-bradycardia-widening QRS, hypotension
Norepinephrine to treat hypotension and decreased cardiac contractility
Atropine or Isoproterenol-Bradycardia and Cardiac Blocks
Verapamil (Calan, Covera, Isoptin Verelan)
Class IV antidysrhythmic
Calcium channel blocker
, Inhi
Pril/ace inhibitors - ANSWER Enalapril/Vasotec
PRIL-is the ending for ace's
Reduces Angiotensin 2 and aldosterone levels
Prevents Angiotensin 1 from converting to Angiotensin 2 in the lungs-
leaves the Angiotensin 1 hanging in the lungs-creates irritation-cough
Vasodilation-mostly arteriole (decreases afterload)
Excretion of sodium and water-retention of K (decreases preload)
Treats hypertension and heart failure
Do not take 2nd and 3rd Trimester of pregnancy
SE = Angioedema-allergic reaction-swelling of tongue, throat-stop
taking and notify md
Hyperkalemia-monitor for widening and slowing of pulse/qrs, weakness,
fatigue, avoid high K foods, AVOID SALT SUBSTITUTES-usually
very high in K, avoid potassium sparing diuretics, sport drinks are high
in K also
Orthostatic Hypotension-teach client to sit and stand slowly, enact fall
precautions
Neutropenia/Agranulocytosis-monitor CBC-WBC count, reoccurring
infections
Renal Insufficiency-Monitor weight, edema, I/O, BUN, Cr, and GFR
Hepatic Insufficiency-Monitor AST, ALT, ALK PHOS, Bilirubin
Cough-Cough lozenges, hard candy, increase fluid intake, sleep with
HOB elevated, antihistamines
ACE Inhibitors
Discussed these medications with hypertension
Arb's-Angiotensin receptor blockers, sartan's
No Cough, same effects and side effects as Ace's-just not as potent
Sartan's/angiotension blockers/arb's - ANSWER ...
