Cardiovascular Flashcards
Hypovolemic shock
S/S: pale, diaphoretic, restless
Nursing knowledge: patients are hypotensive, tachycardia, tachypnea
Nursing actions: give oxygen, narrowing pulse pressure
Polyarteritis Nodosa
Inflammation of the small arteries causing a diminished blood
Treatment: Cortisol
Cardiac catheterization
Inspection of pain at site, report of chest pain, lightheaded and nausea immediately following catheterization should be reported to PCP
This uses dye contrast to assess for artery obstruction. Complications include allergic reactions, lactic acidosis ( due to use of Metformin(glucophage), glucophage should be discontinued 24-48 hours prior to and exposure to dye) and kidney failure( dye increases kidney damage)
Catheter insertion
Should never be withdrawn and inserted when resistance is felt. Rather stop he insertion and ask patient to take a deep breathe— this helps relax the urethral muscles and facilitate passage through the prostate gland
Withdrawing blood from a PICC LINE
Discard 3ml-5ml of blood to prevent contamination of blood sample with iv fluid and medications
Use 10ml syringe to flush port
Apply a push -pause technique to reduce the risk of clot formation and damage to catheter
Venous insufficiency
Elevate legs not dangle
Arterial insufficiency
Dangle legs in dependent position not elevate
Beta blocker (LOL to my 4Bs: bradycardia, bronchospasm, blood sugar, blood pressure)
Never MISS !!!!!!!!!
Bradycardia ( decrease heart rate: notify PCP if HR is less than 50) Bronchospasm ( Do not give to asthmatic patients: it increases resistance of airway)
Blood pressure decreases
Blood sugar masked( hyperglycemia)
Hypertensive crisis
Notify PCP
Administer prescribe antihypertensive crisis
Elevate HOB 15-30 to prevent increase ICP
No need to administer fluid because it expands blood volume which in turns increases ICP
Atorvastatin
Huge category X, advice patient to use contraception while taking atorvastatin.
MONITOR LFT at least yearly. Follow low fat diet. Effective for everyone
ACE inhibitors- angiotensin converting enzymes inhibitors —e.g. Lisinopril, captopril
blocks the release of aldosterone and by doing that promote the retention of potassium .
Avoid food high in potassium
Common side effects of ACE inhibitors include orthostatic blood pressure(dizziness), dry cough, hyperkalemia, and angioedema( worst: report immediately)
Tartrazine (yellow food coloring)
No aspirin
Aerobic exercise( cardio exercise)
Regular aerobic exercise are usually recommended over isometric exercise ( heavy weight lifting) and rowing because they can cause a dangerous rise in blood pressure
Warfarin(Coumadin)
Question? The nurse notes that a client taking warfarin sodium ( Coumadin) has an international normalized ratio (INR) of 2.8, what should the nurse do?
The Normal INR is 1.3 to 2.0. The treatment goal of warfarin sodium is to raise the INR to an appropriate value. An INR of 2 to 3 is appropriate for most clients, although for some clients the target 🎯 INR is 3 to 4. 5.
if the INR is above the recommended range, warfarin should be ⬇️ decrease . If the INR is a 2.8, the nurse should plan to administer the same dosage as prescribe.
CONTRAINDICATIONS for WARFARIN!!!!!!
Active peptic ulcers
Alcohol 🍺 use
Recent injuries
Warfarin PT normal values is 9.6 to 11.8
Below the knee amputation
PostOp Care
>Elevate limb to minimized edema but do not elevate for more than 24 hours because of hip flexion
> During the first 24 hours, you may lie the patient prone for 30 minute 3 times per day for a short period of time
Cardio version
Administer sedatives/ hypnotic
Instruct client that medications may cause dizziness or drowsiness
Withhold digitalis 48 hours before procedure to prevent ventricular fibrillation after cardio version
Immediate Treatment for MI
Mnemonic ( MONA) M: Morphine Sulfate O: Oxygen N: Nitroglycerin A: ASA
Treatment for CHF
Mnemonics's ( UNLOAD FAST) U: sit upright N: Nitro L: lasix O: Oxygen A: aminophyline D: Digoxin
F:Fluid decrease
A: Afterload decrease
S: sodium decrease
T: tests, dig levels, ABG, K
Pack Red blood cells administration
Prime the tubing with 0.9% sodium chloride to reduce hemolysis.
Infuse one unit of red blood cell over 4 hours
Use 18-20 gauge needle
Take baseline vitals signs
Verify with another nurse
