- It takes 3 things to pass the NCLEX exam
- Knowledge
- Confidence
- Exam Proficiency
- You can’t apply what you don't know, but you have to be able to apply what you do
know.
- Go with majority: if something is 75% fatal, consider it fatal.
- If you try to learn everything you will master nothing.
Lecture 3 Cardiac Medications, Cardiac rhythms, Chest tubes, Newborn Heart Defects, Isolation Precautions
Cardiac Medications
- Calcium Channel Blockers:
- Calcium channel blockers are like Valium (sedative) for your heart.
- Valium calms you down, which means calcium channel blockers calm the
heart down
- Example: if at patients heart is tachycardic a calcium channel blocker
will calm the heart and reduce the heart rate.
- Calcium channel blockers should only be used if the heart needs to rest. If it
does not need a rest, do not give calcium channel blockers.
- Calcium channel blockers classification:
- Negative Inotropic: weaken force of muscular contractions.
- Negative Chronotropic: decrease heart rate through electrical conduction.
- Negative Dromotropic: slows the electrical conduction through the heart.
- Together these effects calm the heart down.
- When would a Calcium channel blocker be used? 1 / 2
STUDYMAFIA
- A: Anti Hypertensive: relax heart and blood vessels.
- AA: Anti Angina drugs: relax the heart, which decreases oxygen demand.
- AAA: Anti Atrial Arrhythmia: treats atrial arrhythmias.
- Side effects:
- H and H: Headache and Hypotension
- Names of Calcium channel blockers:
- Calcium channel blockers are any medication ending in “dipine”
- Examples - Amlodipine
- Felodipine Has to have the “di” before “pine”
