Q

how to calculate cardiac output

A

to calculate the amount of blood ejected in each MIN
you have to multiple SV(amount of blood ejected each heart beat) and heart rate(heart beats per minute)

Q

what are we looking at when we look at a 12-EKG

A

its a ONE TIME THING we want to see the rhythm
that there has to be a P before every QRS
R to R distance is the same
QRS and T should be same direction
HEIGHTS DONT MATTER
hor: time
ver: amplitude
with hor and ver = you can calculate the heart rate.

Q

what does each part of EKG mean

A

P: atrial depolarization
QRS: v depolarization and unseen atrical repolarization
T: v depolarization
U: you shouldn’t see this wave. if you do this is bad because its disease. its the Purkinje fibers contracting.

Q

coronary atherosclerosis patho

A

coronary arteries give oxygen to heart muscles.
atherosclerosis is when cholesterol and lipids are building up and turning into a plaque(atheroma) to obstruct circulation.
THROWBACK: fatty streak starts to happen as a kid. but not all of them turn into lesions so it depends on their genetics or smoking or HTN. the lesions will trigger an inflammatory where monocytes(WBC) and platelets gather up. the smooth muscle starts to grow. the smooth muscle has a fibrous cap that covers the inflammation and lipids that is unstable. at some point its going to rupture. when this ruptures, more platelets/clotting factors causing blood to POOL. obstruction will cause an MI!!!

Q

educate your parent with hyperlipidemia on diet

A
  • MEDI DIET: veggies and fish and only red meat 2 a twice
  • watch cholesterol should be less than 200mg PER DAY
  • sat fat should be 7 percent of the calories
  • fat should be between 25 to 35 percent of total calories(total calories depends on your weight) most fat should come from mono fats (20 percent) whereas poly is 10
  • carb is 50 to 60 percent

Q

educate your hyperlipidemia patient on smoking

A

smoking is bad because it can 1. activate your sympathetic NS and this causes an increase in HR and BP vasoconstriction which does not allow blood passage. 2. damages your BV so you increase in platelet aggregation. if the platelets stick together then clots can happen. 3. also hemoglobin will bind to CO2 instead of O2

  12. what is a positive test?
  13. what should the nurse start and monitor?
  14. what should the patient do and should not do AFTER test?
A
  1. signed consent for CABG in case patient has heart attack and wear comfy shoes and clothes. make sure they do NOT work out three hours before this stress test
  2. baseline vitals
  3. stressing the heart to see how well the coronary arteries work. we want get 80 to 90 percent of HR
  4. arm cramp, treadmill, vasodilators
  5. flushing, HA, dizzy(annoying izzy is blushing)
  6. 1-3 hours
  7. max HR= 220- age
  8. alc, tobacco, caf
  9. yes, 4 hours NPO
  10. beta blockers because it drops the HR
  11. patient compains of chest pain, dizziness, fatigue, cramping.
  12. Pt complains EKG or vital changes STOP its a positive test
  13. IV SITE in case patient has a heart attack. Monitor the vital signs via telemetry and cold and clammy
  14. no baths after 1-2 hours after stress test because their vessels are dilated from the vasodilator or exercise.

  13. Patient should be in what position
  14. How long should the patient should be in that position?
  15. Why is the patient in pain after cath lab?
A
  1. signed consent because patient can have ANOTHER MI so we gotta do CABG
  2. plavix and aspirin
  3. HELL YEAH GOLD STANDARD
  4. PCI: this procedure checks how bad the CAD is and stenosis. CAN USE WITH DYE so the doc is gonna go into via groin area into the femoral artery ALLL way to the coronary artery with a balloon tipped catheter to where the plaque is. The ballloon will INFLATE to crack that plaque and deflate and remove the balloon. 60 min procedure. CAS: Coronary artery stent: same shit but when balloon is up. a MESH STENT will be up there for structural SUPPORT. sometimes the doctor will coat the STENT with ASA. Atherectomy: shave that plaque
  5. narrowing of CORONARY blood vessels
  6. Assess renal function (UO), allergies,
  7. warm, flushed feelings
  8. yes, 8 hours
  9. VITAL SIGNS
  10. over 6 hours, every 15 mins in first hour, second hour 30 times 2, every hour times 4
  11. ASSESS GROIN FOR HEMATOMA (it should be soft. bad if its hard because hematoma is painful and its basically blood trapped under skin. Patient is going to be sleeping so they won’t know. Assess pedal pulses.
  12. Use a doppler for pedal pulses and marker it.

  8. if they should ambulate, how many feet
  9. What labs should the nurse monitor
A
  1. signed consent
  2. baseline vitals and INCENTIVE SPIROMETRY
  3. this procedure is when a vessel from the leg is chosen and grafted to the occulded site to let more blood flow.
  4. check the small one on leg and big one chest
  5. stop the anti coags and platelets because of BLEEDING
  6. VS, UO (kidney damage), LOC, Aus Lungs Heart & Abdodmen, Tele

LAY YO HEAD ON MY PILLOW

lay their head so the blood can go to the brain

elevate legs 15 to 30 degrees

Trendelenburg

FLUID BOLUS

79
Q

HTN nursing process

A
  • assess
    • BP
    • heart, kidneys, eyes, brain check
    • aus lungs why? because fluid retention. secondary HTN can be from NSAIDs, kidney problems.
    • SES
  • NI
    • educate on noncompliance
    • older patients and orthostatic hypotension and involve their family because they can forget

and

WHY

A

SEVERE BACK PAIN

that AAA IS PRESSING ON THE LUMBAR NERVES

96
Q

how will a ruptured AAA affect vitals and labs

A

H and H drop

BP and HR rise

because of bleeding

97
Q

surgeons will open up that vessel and place a graft (a man made tube) to replace the weakened vessel wall AFTER IT RUPTURED

incision: midline abdomen

98
Q

what is endovascular grafting

where is that incision

A

similar to cath lab.

surgeon will thread his way to the weakened vessel and put a stent there to get rid of that built up blood pressure.

GROIN

99
Q

how do you check endovascular grafting post op

A

SAME AS CARDIAC CATH

SO PLEASE LOOK AT THOSE

100
Q

hypovolemic shock

A

when your blood cant pump anymore because there is just too much fluid or blood loss

101
Q

what do you do if the AAA ruptures

A

doctor will want to do surgery but you start the IVs because we got to get that fluid(normal saline) and and blood transfusions running. thats your job as a nurse when vitals are tanking (comp mechanism)

102
Q

AAA post op directions
