CARDIOVASCULAR/NCLEX RN Mastery Flashcards
Cardiovascular
- Describe Acute kidney injury
- How is it dx?
- abrupt loss of kidney fxn due to decrease renal blood flow
- dx via
- Increase BUN
- Increase Creatinine
- anuria
Cardiovascular
Monitoring progressive Cr levels tells you what?
If kidney fxn is improving by the process of effective tissue perfusion. The monitoring promotes/data collection, this can support that kidneys are improving perfusion
Cardiovascular
Left-sided heart failure
Left ventricle diminshed ability to pump blood leading to __1?__ in the pulmonary circulation causing pulmonary __2?__
- back pressure
- pulmonary edema
Cardiovascular
Left-sided heart failure s/s (5)
- dry cough
- crackles
- cyanosis
- dyspnea
- tachycardia
Cardiovascular
Right-sided heart symptoms are caused by diminished ability of right ventricle to pump blood.
- This causes blood to pool in 4 places
- extremities
- abd
- neck
- liver
Cardiovascular
Right-sided heart failure s/s (4)
- Peripheral edema
- ascites
- Jugular vein distention
- hepatomegly
Cardiovascular
Can decreased Cardiac Output cause angina and dyspnea with activity?
Yes
Cardiovascular
Normal cardiac output range in liters per min
4-8 L/min
Cardiovascular
4 physical conditions that can cause Malignant HTN or Hypertensive crisis
Hint
- neo___
- glomerulon___
- Hyper___
- Pheo___
- Neoplasm
- glomerulonephritis
- hyper thyroidism
- pheochromocytoma
Cardiovascular
HTN Treatment Mnemonic
A
B
C
D
ACE inhibitors/ARGs
Beta blockers
Calcium channel blockers
Diuretics
Cardiovascular
Mobitz Type 1 Block
- What is a second-degree AV block?
- Mobitz type 1: what degree heart block? Mild or Moderate
- Rhythm stable or unstable
- Mobitz type 1 aka Wenckebach phenomenon what is this?
- Mobitz type 1 caused by?
- PR intervals
- followed by blocked ? wave and dropped ?
- Is treatment needed?
- Prognosis?
- Mobitz type 1 does not often result in clinical manifestations why?
- Problem with electrical conduction system between atria and ventricles
- Second-degree heart block, mildest form
- Rhythm stable
- QRS complexes are grouped into 2s, 3s, 4s ect
- Block of AV node
- PR intervals are prolonged
- blocked P wave and dropped QRS complex then the cycle starts again
- usually benign no tx
- better than type 2
- because ventricular rate is adequate
Cardiovascular
- S/S of acute MI? (3)
- Is this a medical emergency?
- initial assessment?
- Priority nursing intervention?
If using ABC…ciruculation is impaired thus oxygenation to the heart is impaired PRIORITY OXYGEN adm followed by call MET medical emergency team
Norepinephrine is a catecholamine affect of on oxygen? (2)
- s/s
- chest and shoulder pain radiates down left arm
- sweating
- SOB
- yes
- already indicated by pt currently manifesting s/s of MI
- Oxygen via nasal cannula, admin nitro
- Norepinephrine increases use of oxygen thus decreasing the supply
Cardiovascular
Claudation to extremities
- Cold or warm compress? (we want to promote circulation)
- claudation caused by narrowed or occluded ?
- Warm
- ARTERIES
Cardiovascular
Axillofemoral bypass graft?
no belts
ok to exercise and stand
Axillofemoral bypass is an extra-anatomical grafting procedure performed for patients with severe aortoiliac occlusive disease to improve arterial blood flow to the lower extremities. Revascularization procedure. The axillary artery is connected to the femoral artery via an artificial graft. femoral artery anastomosis
Cardiovascular
- What is secondary HTN?
- What is primary HTN?
Secondary hypertension (secondary high blood pressure) is high blood pressure that’s caused by another medical condition. CAUSE IS IDENTIFIABLE
- Renal disease
- Cushing
- Hyperthyroidism
- Hormonal contraceptives
- diabetes
- hyperaldosteronisn
- pheochromocytoma
Secondary hypertension differs from the usual type of high blood pressure (essential hypertension), which is often referred to simply as high blood pressure. Essential hypertension, also known as primary hypertension, has no clear cause and is thought to be linked to genetics, poor diet, lack of exercise and obesity and Vit D deficiency
Secondary hypertension can be caused by conditions that affect your kidneys, arteries, heart or endocrine system. Secondary hypertension can also occur during pregnancy.
Proper treatment of secondary hypertension can often control both the underlying condition and the high blood pressure, which reduces the risk of serious complications — including heart disease, kidney failure and stroke.
