Week 3 CVS Drugs (p1)

Question 1

Drug Classes w3 (p1)

Answer 1

Beta Blockers (end in ‘OLOL’)

Anti-arrhythmia ( Digoxin)
Anti- arrhythmia ( Amiodarone )

Calcium Channel Blockers (end in ‘pine’)

Question 2

Beta Blocker
Examples, Indications, MOA, AE, NC

Answer 2

Examples (MABS)
- Metoprolol
- Atenolol
- Bisoprolol
- Sotalol

Indications
- Used for hypertension
- Heart failures,
- Angina, MI
- Tachyarrhythmia (aka tachycardia - high HR)

MOA
- Beta 1 works in the heart and Beta 2 works in the lungs
- These medications work by reducing cardiac contractility (HR) by depressing sinus node rate & slowing conduction of AV nodes.

Ad. effects:
- Nausea
- Hypotension
- bradycardia (slow HR)
- bronchospasm

Nursing Considerations
- Monitor BP & HR before and after
- Reduce dose gradually
- Complete postural BP

Question 3

Anti-arrhythmia (Digoxin)
Indications, MOA, Adverse effects & Nursing Considerations

Answer 3

Indications for:
- Heart failures
- Atrial arrhythmia (AFibs)
- Cardiac Glycosides: increase the output force of its heart but decrease its rate of contractions

MOA:
- increases the efficiency of the heart to improve
- influences the movement of ions in & out of myocardial fibres (heart muscles).
- decreases sympathetic activities

AE:
- N/V
- CNS disturbances
- digoxin toxicity

NC:
- assess signs & symptoms of digoxin toxicity
- monitor renal functions
