Exam 2 (HF, Arrythmia, Clotting) Flashcards
Metoprolol indications and actions
- What are the indications?
(Think BP and Nala)
- Action: What does it block?
- what does it “have”
- HTN
- Acute MI
- Angina Pectoris
- HF
Action
- Blocks Beta 1 receptors
- Has negative chronotropic effect
Metoprolol pharmacokinetics
- What 2 routes?
- Is it an extended or short-release form?
- How to dose? (trick question)
- Orl and IV
- Extended-release
- Dose varies by severity of HF
Adverse effects of Metoprolol
- What can it worsen?
- Can it increase or decrease HR (name for it)
- What to monitor
- can worsen HF - if given during acute exacerbation
- Bradycardia
- Monitor HR and BP
What are contraindications of Metoprolol?
- 2 contraindicaionts
What are cautions when taking metoprolol (People with “blank” should not have it
- can you stop the med abruptly
- heart block and sinus bradycardia
- caution with asthma, COPD, CHF
- do not stop abruptly!!!
What are the uses of Cardia Glycosides?
Digoxin (Lanoxin)
- Treats what 2 heart issues?
- can it decrease or increase life span??
- Treats HF and Treats arrhythmia
- Decreases life span - due to inotropic effect
What are the actions of Digoxin
- Increases the ______ of myocardial contraction
- slows conduction of what?
-Its contraindicated with what 2 issues
- does it increase or decrease urine output?
-slows conduction of electrical impulses through the heart Increases strength
- contraindicated with bradycardia or heart block
- Increases urine output
Why is it important to check the Digoxin level
- (why would you need to be cautious with this drug?
Cautions:
- what are cautions in digoxin
- in older or younger patients
- does it affect kidneys
- any cautions with heart issues or thyroid
- Narrow margin of safety; narrow therapeutic range (0.5-2.o ng/ml)
caution
- older patient
- renal impairment (must check renal function)
- MI
-Thyroid disorders
Can digoxin cause cardiac dysrhythmias?
- does it cause obesity, no cause or vomiting or abd pain
- Can it cuase an electrolyte imbalance?
- can it lead to headaches, weakness, viual disturbances, and confusion
- yes
- no it can cause anorexia, NV and abd pain
- yes
- yes
Which drug has an adverse effect where you have yellow vision?
Digoxin
What type of pulse do you check before giving digoxin?
- what also do you monitor?
- Should you check digoxin lvels regularly
Apical pulse
- Monitor labs, including drug levels, electrolytes, Mg, Ca, renal labs
- Yes, check regularly
What is the drug name for short-term therapy for advanced HF
Phosphodiesterase Inhibitors
Phosphodiesterase Inhibitors works by inhibiting enzyme in cardiac muscle resulting in More Ca+ for cardiac contraction. This causes increased contractility and vasodilation. What type of effect is this?
Inotropic effect
Phosphodiesterase inhibitors are given in which route only
IV route only
What are the contraindications for Phosphodiesterase Inhibitors?
- What type of MI?
- Fluid volume defecit or excess?
- arrythmias in ventrical or atrium
- Allergy
- Severe aortic or pulmonic disease
- Acute MI
- FV deficit
- Vent. arrhythmias
What are the adverse effects of Phodiesterase
- Arrythmias
- HTN
- Chest Pain
