Week 1 Drugs (Adenosine, Ventolin, Amiodarone, Aspirin) Flashcards
1
Q
Adenosine
Pharmacology and Actions
A
- Slows conduction through the AV node
- Most cases of PSVT involve AV nodal reentry, adenosine interrupts AV nodal circuit stopping tachycardia and restoring normal sinus rythm
2
Q
Albuterol Sulfate
Pharmacology and Actions
A
- Beta-2 andrenergic bronchodilator
- Beta-2 agonist that relaxes bronchial smooth muscle, resulting in bronchial dilation
- Beta-1 overlap with clinically significant cardiac effects such as tachycardia
- Shift potassium intracellular, resulting in lower serum potassium
3
Q
Amiodarone
Pharmacology and Actions
A
- Multiple effects on sodium, potassium and calcium channels
- Prolongs action potential and repolarization
- Decreases AV conduction and sinus node function
- Also has some alpa- and beta-adrenergic blocking properties
4
Q
Aspirin
Pharmacology and Actions
A
- Inhibits prostaglandin and disrupts platelet function
- Mild analgesic and anti-inflammatory
5
Q
Adenosine
Indications
A
- Convert hemodynamically stable narrow complex regular tachycardia with a pulse
6
Q
Albuterol Sulfate
Indications
A
- Treatment of bronchospasm
- Treatment of hyperkalemia
7
Q
Amiodarone
Indications
A
- V Fib
- Pulseless V Tach
- Reg wide complex tachycardia w/ pulse
- Irreg wide complex tachycardia
8
Q
Aspirin
Indications
A
- Cardiac chest pain
- Suspected acute coronary syndrome
9
Q
Adenosine
Contraindications
A
- 2nd or 3rd degree heart block
- Poison or drug induced tachycardia
- Known hypersensitivity
- Allergy
10
Q
Albuterol Sulfate
Contraindications
A
- Allergy
11
Q
Amiodarone
Contraindications
A
- 2nd or 3rd degree AV blocks
- Allergy
12
Q
Aspirin
Contraindications
A
- Active GI bleed
- 324mg taken in pst 24 hours
- Allergy
13
Q
Adenosine
Precautions and Side Effects
A
- May cause brief asystole, facial flushing, dizziness, headache, nausea and transient shortness of breath
- IV/IO adenosine has been shown to produce bronchospasm in asthmatic pts
- If pt becomes hemodynamically unstable, cardioversion should occur
14
Q
Albuterol Sulfate
Precautions and Side Effects
A
- May cause dizziness, headache, anxiety, palpitations, sweating and muscle tremors
- Clinically significant arrhythmias may occur in pts with underlying cardiac disorders
- Relative contraindication include symptomatic tachycardia, tachyarrythmias and anginal chest pain
15
Q
Amiodarone
Precautions and Side Effects
A
- May cause hypotension and bradycardia
