Q

Adenosine administration?

A

6mg IVP bolus over 1-3 seconds followed by a 20ml flush then elevate the extremity.

Q

Amiodarone: Whats a major adverse effect? What should the nurse monitor?

A
  1. POTENTIATES ARRHYTHMIAS, nurse should monitor for Torsades
  2. BB warning for Pulmonary and liver toxicities (monitor PFTs and liver enzymes)

Q

Amiodarone: How does it work?

A

Decreases the defib threshold, making the body respond easier to the shock (shock is more effective)

Q

Atropine: When do we give it?

A

Symptomatic (dizziness, hypotension, syncope, diaphoretic) sinus brady 1st line drug, also for organophosphate poisoning in extremely high doses

Q

Atropine:

  1. How does it work?
  2. When should we not give it?
  3. Whats a quick way to remember when to not give?
A
  1. anticholinergic drug that blocks the action of the vagus nerve (want HR faster)
  2. Not for 2nd degree type 2 and 3rd degree heart blocks. Consider epi/dope and external pacing. WONT WORK ON HEART TRANSPLANT PTS (no vagus nerve)
  3. ” no p waves= dont give the drug with a P in it”

Q

Atropine:

  1. When should I not give it? Why?
  2. What happens if the dose is below 0.5 mg?
A
  1. Use cautiously in MI/hypoxia (increases myocardial o2 demand), avoid in hyperthermic bradycardia (Slowly warm pt)
  2. May result in paradoxical slowing of the HR, this is why we never want a dosage below 0.5 mg

Q

Atropine:

  1. Dosage
  2. What should we do if atropine administration doesn’t help the bradycardia?
A
  1. 0.5mg IV every 3-5 mins as needed. Don’t exceed the total dose of 0.04mg/kg (total 3mg)
  2. Consider pacing or epi/dope

Q

Dopamine:

  1. Why do we give it?
  2. Whats the major side effect?
A
  1. 2nd line for symptomatic brady
    - use for hypotension (SBP <70) with sxs of shock
  2. Causes tachyarrhythmias while increasing BP and contractility

Q

Dopamine:

  1. What do I need to do before giving dope?
  2. What do I need to watch for?
  3. What should I not mix with this? Why?
A
  1. Correct hypovolemia
  2. Tachyarrhythmias, vasoconstriction (blue fingertips), extravasation (watch iv sites- prefer a CL)
  3. Don’t mix with sodium bicarb (wouldnt work)
17
Q

Dopamine:

  1. Rate?
  2. How do we titrate?
  3. What about when we want to taper?
A
  1. 2 to 20 mcg/kg/min
  2. titrate to response
  3. Taper slowly (rebound brady) so keep on a heart monitor!
18
Q

Epinephrine:

  1. When do we give?
  2. When would this be used for symptomatic bradycardia?
  3. How does this work?
A
  1. Cardiac arrest- VF, pulseless VT, asystole, PEA, severe hypotension, anaphylaxis
  2. Drug of choice if atropine is un-effective
  3. Vasoconstrictor, so it increases MAP, which increases perfusion of blood to the heart and brain
19
Q

Epinephrine:

  1. Contraindications?
  2. How is it given?
A
  1. Increased HR and BP can cause myocardial ischemia, angina, and increased myocardial demand
  2. Anaphylactic dose is IV ONLY (will cause a cardiac event if pushed)
20
Q

Epinephrine:

  1. Dosage for cardiac arrest
  2. Dosage for profound bradycardia
A
  1. 10 ml every 3-5 mins with a 20 ml saline flush after. Elevate arm after. Continuous infusion of 0.1-0.5 mcg/kg/min
  2. 2-10 mcg/min infusion
21
Q

Lidocaine:

  1. When do we give it?
  2. What do we need to know before giving?
  3. Drug class?
A
  1. Alternative to amiodarone in cardiac arrest VF/ pulseless VT
  2. weight-this is weight based!
  3. sodium channel blocker
22
Q

Lidocaine:

  1. Dosage for VF/PVT?
  2. Dosage for perfusing arrhythmia?
  3. Dosage for maintenance dose?
A
  1. 1-1.5 mg/kg IV. May have additional dose of 0.5-0.75mg/kg IV repeat in 5 mins for a max of 3 doses (or total 3mg/kg)
  2. 0.5-0.75mg/kg IV, repeat in 5 mins for a total of 3 doses or 3mg/kg
  3. 1-4mg/minute IV (30-50 mcg/kg)
23
Q

Lidocaine:

  1. Toxicity symptoms?
  2. What should I do to the dosage if my pt has impaired liver function/ LV dysfunction?
  3. When should I discontinue this drug?
A
  1. dizziness, drowsiness, fatigue, twitching, mouth numbness, slurred speech, tremors, GI effects, respiratory distress/arrest
  2. Reduce maintenance dose but not loading dose
  3. D/C for signs of toxicity
24
Q

Magnesium sulfate:

  1. When is this given?
  2. What is it/ what does it do?
A
  1. Torsades or when low mag, or for life threatening ventricular arrhythmias due to dig toxicity
  2. Smooth muscle relaxer that decreases respirations
25
Q

Magnesium sulfate:

  1. What is the main adverse effect if given too fast?
  2. What should the nurse watch for?
  3. How should this be given?
  4. Dosage for cardiac arrest?
  5. dosage for torsades (with a pulse) or a MI with hypomagnesemia?
A
  1. Respiratory depression or arrest with rapid administration.
  2. Occasional drop in BP and respirations with rapid administration
  3. SLOWLY… too fast causes hypotension and tachycardia and the pt might need a ventilator
  4. 1-2g diluted in 10ml (ns/d5w) given IV
  5. Loading dose of 1-2 grams mixed in 50-100 ml of dilutent over 5-60 min
