Q

What calcium channel blockers are given after heart attacks? Why?

What is an adverse effect when taking this?

A

nifeDIPINE - declined BP and HR
diltiaZEM - zen yoga for heart
verapAMIL - chill heart

calms BP and HR from dysrhythmias after heart attack

adverse: BLE edema

25
Q

What stool softener is giving after heart attacks? Why?

A

docusate sodium
prevents from straining because the pt can bear down which results in decreased HR (valsalva maneuver)

26
Q

What are post heart attack complications?

A

DARTH VADER

Death
Arrhythmias (dysrhythmias)
Ruptures
Tamponade
Heart failure (Right vs Left Acute vs Chronic)

Valvular disease
Aneurysm
Dressler’s Syndrome
Embolism
Recurrence

27
Q

What are examples of dysrhythmias? What do they mean?

A

atrial fibrillation - ventricular tachycardia - ventricular fibrillation - asystole (death)

hearts last effort to save itself

28
Q

What is the treatment for ventricular fibrillation?

A

defibrillation

29
Q

What should a nurse ask a pt who has afib?

A

smoking hx

30
Q

What is a person at risk for who has afib?

A

cerebrovascular accident (CVA)

left atria can’t pump blood - clot can form - clot can cause embolic stroke

31
Q

What is the treatment of heart failure?

A

ACE inhibitors

32
Q

What is the difference between left and right sided heart failure?

A

HF = heart failure (heavy fluid)

Right
- ROCKS body with fluid
- peripheral edema

Left
- LUNG fluid
- pulmonary edema

33
Q

What is pericarditis? What causes it?

A

inflammation outside the heart - heart gets compressed and can’t pump

less cardiac OUTput = less oxygen OUT

causes: HAIR
- Heart attack
- Autoimmune disorders
- Infection
- Renal failure

34
Q

What are the clinical manifestations of pericarditis?

A
  • pericardial friction rub
  • pulsus paradoxus (> 10mmHg BP systolic drop while pt holds breath)
  • pleuritic chest pain (rib cage)
  • dyspnea
  • fever (>100.4)
35
Q

What diagnostic studies can be done for pericarditis?

What will the labs show?

A

ECG (ejection fraction)
Blood culture (infection in blood)
Throat culture (strep)
CXR, CT scan
Pericardiocentesis (drains fluid or blood in heart sac)

Labs:
- increased WBC (>10,000)
- increased troponin
- increased ESR and c-reactive protein (markers for inflammation)

36
Q

What indicates that a pericardiocentesis worked?

What should be monitored after?

A

increase in BP = increase in cardiac output

signs of pneumothorax

37
Q

What medications are used for pericarditis?

A

NSAIDS
Corticosteroid
Colchicine
Antibiotic

38
Q

What NSAID is given for pericarditis? Why?

A

indomethacin

decrease inflammation

39
Q

What corticosteroids are given for pericarditis? Why?

A

methylprednisolone
solumedrol
prednisone

treats inflammation

40
Q

What is colchicine? How is it used for pericarditis? What should be monitored?

A

plant poison used for gout

treats inflammation

monitor N/V and diarrhea

41
Q

What is endocarditis?

A

inflammation inside the heart, heart valves can’t fully close

infective = bacteria, mold on heart valves
noninfective = no bacteria, only inflammation

less cardiac output = less oxygen out

42
Q

What are causes of endocarditis?

A
  • dirty needles (IV drug abuse)
  • heart sx (prosthetic valves or CABG) bacteria easily comes
  • untreated strep throat
43
Q

How is endocarditis treated?

A

Antibiotics (blood culture first then broad spectrum antibiotics)

Valve repair or replacement

44
Q

What are the clinical manifestations for endocarditis?

A

fever
murmur (aortic/mitral valves)
tachycardia
Roth spots (eyes)
petechiae (capillary rupture)
splinter hemorrhages (nailbed)
Osler nodes (raised bumps fingers/toes)
Janeway lesions (bruises palms/soles)

45
Q

What are the diagnostic studies for endocarditis?

What will the lab show?

A

Blood culture
CXR
ECG
Cardiac catheterization

Lab:
Increased WBC, ESR, C-reactive protein

46
Q

What are the nursing interventions for endocarditis?

A

MOLD

Monitor for infection and s/s of stroke (neuro check)
Oral care
Let all providers know Hx of endocarditis
Dental tx: antibiotics prior to tx

47
