Random Cardiovascular

Question 1

Symptoms that require treatment of tachycardia or bradycardia?

Answer 1

Hypotension
AMS
Signs of shock
increased chest discomfort
acute heart failure

Question 2

treatment modalities for symptomatic regular monomorphic tachycardia?

Answer 2

adenosine

synchronized cardioversion

Question 3

medications for wide QRS tachycardia?

Answer 3

Procainamide
amiodarone
sotalol

Question 4

What is the typical heart rate of a tachyarrhythmia?

Answer 4

150 or greater

Question 5

what is the typical heart rate of a bradyarrhythmia?

Answer 5

less than 50

Question 6

What is the first intervention for any dysrhythmia?

Answer 6

patent airway and oxygen

Question 7

What is the first line treatment for bradycardia?

Answer 7

atropine

Question 8

What should you do if atropine isn’t effective in treating bradycardia?

Answer 8

Epinephrine
Transcutaneous pacing
Maybe: Dopamine

Question 9

What medication can replace doses 1 and 2 of epinephrine in a code situation?

Answer 9

vasopressin

Question 10

Are P waves present in PJCs?

Answer 10

sometimes, if they are it is from retrograde conduction of the atria.

Question 11

At what K level would you start to see peaked T waves?

Answer 11

6 to 7

Question 12

At what K level would you start to see QRS widening?

Answer 12

8 to 9

Question 13

What else may cause peaked T waves?

Answer 13

Early mi

May be normal for that client

Question 14

What else may cause QRS widening?

Answer 14

Quinidine and procainimide toxicity

Question 15

What happens when K reaches 10?

Answer 15

P wave becomes indiscernible

Question 16

When do sine waves occur?

Answer 16

K levels above 12

No identifiable QRS (merged with T wave)

Question 17

What happens when potassium reaches 3?

Answer 17

U and T waves are same height

Question 18

What happens when K reaches 2?

Answer 18

U wave starts to become higher than T wave

Question 19

What happens when K reaches 1?

Answer 19

U waves resemble T waves. QT interval is same but not measurable because of fusing of two waves

Question 20

What is the major ECG finding with hypercalcemia?

What else can occur occasionally?

Answer 20

Shortening of the QT interval (usually due to shortening of ST segment)

ST depression or T wave inversion

Question 21

What ecg changes can happen with hypocalcemia? What can occasionally happen?

Answer 21

QT lengthens because of ST lengthening.

May have inverted T wave

DONT MISTAKE QT LENGTHENING WITH QTU INTERVAL SEEN WITH HYPOK

Question 22

What else can prolong QT interval?

Shortening?

Answer 22

Cerebral vascular disease, Post cardiac arrest, some antiarrhythmics

Digitalis
