- 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.

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?
- 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”
