Q

Channel Blockers are also known as?

A
  1. Negative Inotropes
  2. Negative Dromotropes
  3. Negative Cronotropes
    These are cardiac depressants that relax your heart and calm it down.

Positive Inotropes
Positive Dromotropes
Positive Cronotropes
These are cardiac stimulators that speed up your heart!

Q

When do we use Calcium Channel Blockers? and how do we TX.? Think: A, AA, AAA

A

A = Anti Hypertensives = relaxed heart vessels therefore decreases blood pressure.

AA = Anti Angina Drugs = relaxes heart therefore decreased O2 demand. The worst thing that can happen to a pt. with angina is to speed up their heart.

AAA=Anti Atrial Arrhythmia = Tx. all problems in atria and supra(above) ventricular tachycardia.

Therefore, Calcium Channel blockers tx. all Atrial probems.

Q

What must the nurse do before giving a calcium channel blocker?

What and when must you hold a calcium channel blocker?

A

Check BP because Hypotension is a side effect.

HOLD the Calcium Channel Blocker if systolic is < 100.
i.e. 98/52, if on I.V. then titrate (slow it down) drip so, it slows down and systolic stays above 100.

    • Doesn’t matter if upset down
  2. Ventricular Fibrillation (v-fib)
    • no pattern
    • CHAOTIC (CF), squiggly line.

Q

What are 10 rules you must know when reading rhythm

strips?

A
  1. QRSTD Polarization = ventricular (rule out atrial).
  2. P. WAVE = Atrial (rule out ventricular)
  3. A lack of QRS = ASYSTOLE
  4. Flutter is always described as saw tooth.
    “ I saw the teeth and my heart did flutter”
  5. Chaotic = Fibrillation
  6. Bizarre = Tachycardia
  7. Periodic = PVC
  8. High Priority: > 6 PVC’s in a minute, or in a row, or if the PVC falls on the t-wave of the previous beat.
  9. Salvo of PVC = a group of PVC is short run of vtach.
  10. PVC pts. are low priority unless they fall under these 3 circumstances then they increase to moderate:
    1. More than 6 PVC in a minute
    2. More than 6 PVC in a Row
    3. If PVC falls on the T-wave of previous beat
      Aka: R on T Phenomena, then elevate priority of PVC pt to moderate. So, PCV Pt. never reach high priority. After an M.I. it is good to see PVC because it means they are re-perfusing.

Note: Dont call DOC re: PVC’s unless you want to loss your monitor,

Q

Name the HIGH PRIORITY Lethal arrhythmia’s.

A
  1. Asystole
  2. V-fib
  3. Vtach-is potentially life threatening only difference is that the pt. has a cardiac output (pulse)

Asystole and vfib have no cardiac output therefore zero perfusion = DEAD in 8 minutes!

Q

How do we treat Cardiac Artial/Ventricular Arrhythmia’s?

A
  1. PVC and V-TACH for ventrical use lidacane or Ameoderone.
  2. Artial Arrithmias (ABCD)
    A) ADENOCARD (ADENOCINE) push in less than 8 seconds. Pt. my go into asystole for 30 sec.

B) BETA BLOCKERS “LOL” negative ino, chromo, dromo-tropes. So, like valium for heart. Therefore tx. = A, AA, AAA, and side effects = H and H - hypotension and headache.

C) Calcium Channel Blocker - negative ino, chromo, dromo-tropes. So, like valium for heart. Therefore tx. = A, AA, AAA, and side effects = H and H - hypotension and headache. Differerence: better for pt. with asthma

D) Digitalious, Digoxin, Lanoxin - all the same.

Q

What is the purpose of a chest tube?

A

To re-establish negative pressure in the pleural space. So, lung expands when chest wall moves. The plural space is a space NEGATIVE - GOOD! makes things stick together therefore good air exchange allows breathing in/out.

Q

When you get a chest tube question look at the reason the chest tube was placed for example: Pneumthorax, Hemothorax and Pneumohemothorax. Explain each.

A

Pneumothorax - Pneumo (Air), chest tube removes air. In Pneumothorax positive air is placed therefore a chest tube is inserted to establish negative air.

Hemothorax - Hemo (blood), chest tube removes blood, which creates positive pressure. Therefore chest tube is placed to remove and re-establish negative pressure.

Pneumohemothorax - Pneumohemo ( Air and Blood), Chest tube removes air and blood, therefore chest tube is placed to re establish negative pressure

Q

Question: If you have a pt. with chest tubes in for Hemothorax what would you report to the DOC?

  1. Chest tube not bubbling
  2. Chest tube drained 800ml in first 10 hrs
  3. Chest tube is not draining
  4. Chest tube is intermittently bubbling

Note: Ask what would you expect from a hemo? removal of blood aka - drainage

A
  1. Chest tube is not draining

Pick this answer b/c its not doing what its suppose to be doing.

Q

Question: If you have a pt. with chest tubes in for Pneumothorax what would you report to the DOC?

  1. Chest tube not bubbling
  2. Chest tube drained 800ml in first 10 hrs
  3. Chest tube is not draining
  4. Chest tube is intermittently bubbling

Note: Ask what would you expect from a Pneumothorax ?

A
  1. Chest tube not bubbling
  2. Chest tube drained 800ml in first 10 hrs

Either of thee answers are right because they are not doing what they are suppose to be doing.

Note: to get chest tube questions right you must pay particular attention to the disease the chest tube is tx.

22
Q

What are the 2 locations of chest tubes? What do they do?

A
  1. Apical - chest tube is up high, removes air.
  2. Basilar - chest tube is at bottom of lung, removes blood.

A=Apical-Air (rises)
B=Basilar-blood (sinks)

23
Q

Question:
1. If your Apical is draining 200ml per hour is this good or bad?

  1. If your Basilar is draining 200ml per hour is this good or bad?
A
  1. Bad

2. Good

24
Q

Question:

  1. your apical tube is not bubbling good/bad?
  2. your basilar tube is not bubbling good/bad?
A
  1. Bad

2. Good

25
Q

How many chest tubes and where would you place them for a uni lateral pheumohemothorax?

A

2 tubes
1 x apical
1 x basilar

26
Q

How many chest tubes and where would you place them for a Bilateral Pneumothorax?

A

2 tubes

2x Apical one on either side

27
Q

How many chest tubes and where would you place them for post op surgery?

A

2 tubes because you are to assume that its unilateral unless specified 1 apical or bilateral

28
Q

How many chest tubes would you need for a post -op pneumoectomy?

A

0 because its removing the lung therefore there is no need to re-establish the pleural space.

29
Q

For CLOSED CHEST DRAINAGE devices i.e. pleural vac, pneumovac, emmerson plastic containers. 1) What do you do if you knock one of these over? 2) Is this a medical emergency?

A

1) Set it back up and have pt. take some deep breaths.

2) This is not a medical emergency - Do NOT call DOC.

30
Q

What do you do if the water seal device breaks?

A

1) CLAMP IT - to prevent positive pressure from getting into the pleural space.
2) CUT IT - away from broken device b/c its no good anymore. Stick into sterile water.
3) SUBMERGE in unsterile water.
4) UNCLAMP - because you have re: established water seal.

    " CLAMP, CUT, SUBMERGE, UNCLAMP "
31
Q

Remember that a “BEST” question is different from a “First” question!
If the question is asking you to pick “BEST” thing to do if the water seal device breaks. Do you “ CLAMP, CUT, SUBMERGE, UNCLAMP “ what should you pick?

A

Pick submerge b/c it sloves the problem.

if its an order question “first” pick clamp.

32
Q

“BEST” questions are the answers you pick when you can only pick _____? “FIRST” questions you can______?

A

one

> one

33
Q

Best and First question example:
You notice a pt. have a V-FIB on the monitor.
1. What do you do “FIRST”? a) place back board or b) begin chest compressions?
2. What is the “ BEST”thing to do? a) place back board or b) begin chest compressions?

A
  1. a) place back board
    b) begin chest compressions
  2. Begin chest compressions
34
Q

What’s the “FIRST” thing you do if a chest tube gets pulled out? What’s the “BEST” thing you do if a chest tube gets pulled out?

A 
FIRST = Take gloved hand and cover the hole
BEST= Cover with vaseline gauze
35
Q

For Bubbling Chest Tubes questions what 2 things should you ask?

i.e. Bubbling, Bubbling, Bubbling…..
Ask: Where? Water seal
When? Intermittent = GOOD, Continuous = BAD

A
  1. Where is it bubbling?

2. When is it bubbling?

36
Q

What does it mean if there is continuous bubbling in the water seal?

A

It means there is a leak in the system therefore need to tape it until it stops leaking ( in LPN scope)

37
Q

Is intermittent bubbling in the suction control chamber good or bad?

A

BAD! because if you are only getting intermittent suctioning in the suction control chamber it means that the suction is low therefore you must turn up the dial on the wall until bubbles start bubbling continuously.

38
Q

If something is sealed i.e. water chamber, should you have a continuous bubble?

A

NO! it means its leaking.

i.e. 2 L bottle of pop on the shelf bubbling, would you buy it? No because it means the seal is broken. Therefore in a chest tube if the water seal is broken = BAD!

39
Q

If a water seal bubbling:
Intermittent =?
Continuous =?

A

Intermittent =Good

Continuous = Bad

40
Q

If suction control chamber is bubbling:
Intermittent =?
Continuous =?

A 
Intermittent = BAD means suction is low
Continuous = Good
41
Q

How long are you able to clamp a chest tube for without a Doctors order? What kind of clamps are used?

A

15 secs.

rubber tipped double clamps x 2, so you don’t puncture tubing.

42
Q

Congenital Heart Defects: Every congenital heart defect is either ________ or _____ _________.

A

Trouble or not trouble.

So it either causes a big problem or no problem at all.

43
Q

Describe Congenital Heart Defects using the TRouBLe acronym.

A

T- All heart defects that are TROUBLE begin with “T”
RIGHT- All trouble defects blood stunts from RIGHT to LEFT

LEFT- Acyanotic defects blood shunts from LEFT-RIGHT
e

44
Q

Which Congenital Heart Defects have murmurs?

A

All pt. with Congenital Heart Defects will have a murmur because of the shunting of the blood. Therefore all pt with Congenital Heart Defects will have a Echocardiogram.
