94
Q

What is the gold standard for evaluation CAD and Blockages?

A

Cardiac Catheterization

95
Q

When doing a Cardiac Catheterization, a thin flexible sheath is guided into a large blood vessel in the-

A

Groin, Arm, or Neck

96
Q

During a Cardiac Catheterization, after a catheter is guided into a large blood vessel, where does it get threaded towards?

A

It gets threaded up to the left or right side of the heart

97
Q

After a Cardiac Catheter makes its way into heart during a Cardiac Catheterization, what happens next?

A

Contrast material is injected into the catheter.

Photos are taken as the contrast moves through the chambers of the heart, the valves, and major vessels of the heart.

98
Q

What are stress tests used to evaluate, determine, and diagnose in regards to the heart?

A

Evaluates how well the heart functions during activity + Evaluates Treatment

Diagnoses CAD and Arrhythmias

Determines the risk of suffering a MI

99
Q

How does an X-Ray help give a look into a pt’s cardiac status?

A

It CAN’T detect an MI, but it can detect Cardiomyopathy + Fluid filling the lungs + Any structural abnormalities

100
Q

When assessing a pt with CAD, you should check their BP in-

A

Both arms (Differences between the 2 should be documented)

101
Q

You have a pt with CAD. You take their BP and notice that one arm has a lower BP than the other.
Which arm is used for diagnostic and treatment purposes?

A

The arm with the highest BP

102
Q

When assessing a pt with CAD, you should take note of any indications that Perfusion and Oxygenation are inadequate.
Some examples are-

A

Unrelieved Chest Pain + Restlessness + Changes in LOC

103
Q

What is Perfusion?

A

Perfusion is whether or not blood is being sent to where it needs to be and if the oxygen it carries can get to the tissues that need them

104
Q

When assessing a pt with CAD, you should take note of any indications that Perfusion and Oxygenation are inadequate.
What lab values indicate this?

A

Elevated Troponins, any Elevated ST Segment

105
Q

Pt’s with an elevated Troponin level or ECG changes should initially take what med? How much of it?

A

150-300 mg of Aspirin

106
Q

Pt’s with an elevated Troponin level or ECG changes should have what done after taking Aspirin?

A

Have 2 Large Gauge IV’s initiated

107
Q

Pt’s with an elevated Troponin level or ECG changes should have what done after having 2 Large Gauge IV’s initiated?

A

Administer a single dose of IV Heparin followed by Continuous Infusion

108
Q

Pt’s with an elevated Troponin level or ECG changes are recommended to have what done after having Heparin administered?

A

Antiplatelet Therapy with Ticagrelor or Clopidogrel PO

109
Q

What should be used to treat pain for pt’s with an elevated Troponin level or ECG changes?

A

Morphine, Fentanyl, Nitroglycerin

110
Q

What should be done for a pt who’s undergoing a STEMI?

A

An emergent heart cath and percutaneous intervention

111
Q

You have a pt who’s undergoing a STEMI.
How long do you have to get them a heart catheter and percutaneous intervention?

A

90 Minutes

112
Q

What do you do for a pt who’s undergoing a STEMI, but a Percutaneous Intervention isn’t available or the pt can’t be transferred to a cath lab within 120 mins?

A

Thrombolytics are recommended

113
Q

For pt’s undergoing a NSTEMI or Unstable Angina, what is the first priority?

A

Control of Symptoms + Aspirin and Heparin

114
Q

In all cases of NSTEMI or Unstable Angina, what should be started ASAP?

A

Beta Blockers, Statins, an ACE Innibitor
