To ensure accurate hemodynamic values, Zero and calibrate in supine position, Secure transducer at phlebostatic axis at the
what MUST be done? 4th Intercostal space
If the transducer is TOO high, values will be LOW. If the transducer is TOO low, values will be HIGH
Before placing an arterial line, an Allen Test 1. Elevate hand in a fist for 30 seconds, 2. Press on ulnar and radial artery, 3. Ask the
MUST be POSITIVE. What is the order of pt to release the fist and release ulnar artery, 4. Color returns in 7 to 10 seconds
this test?
To avoid gangrene, necrosis, or loss of Admin IV meds. OK to Obtain continuous BP values, ABG samples, and Flush arterial
limb, a nurse can do all the following in an lines with NS to maintain patency
arterial line EXCEPT...
The MAJOR complication of an arterial line Prevent tube disconnection, Apply pressure for 10 min if a pt is on anticoagulants
is hemorrhage. What MUST a nurse do to when discontinuing, Apply pressure for 3-5 minutes when discontinuing, Prevent line
prevent this? dislodgement
A central venous line only measures RIGHT Place Trendelenburg - supine with feet higher than head - when administering to
ATRIAL pressure. What is true about this prevent an air embolism, Gives CVP and SvcO2 values, You can draw blood, Can
line? administer IV meds + TPN
A pulmonary artery gives values in the PAP - pulmonary artery pressure, SvO2 - mixed venous oxygen, SVR - systemic
ENTIRE RIGHT heart. What are some values vascular resistance, CO - cardiac output
does it give?
Mixed Venous pressure -SvO2) measures returning to the pulmonary artery
the level of O2
If the SvO2 value is less than 60%, what Apply O2, Admin IVFs or inotropes to increase cardiac output, Admin blood
should a nurse do? LOW = DECREASED transfusion to increase hemoglobin
DELIVERY of oxygen)
If the SvO2 is more than 75%, what should Treat shunting of blood in sepsis, Treat microvascular clots in DIC
the nurse do? HIGH = DECREASED
UTILIZATION of oxygen)
, If the CO is less than 4 L/min, what should Admin inotropes, Admin IVFs, Treat MI or cardiogenic shock
the nurse do? LOW= TOO LITTLE blood
being pumped)
If the CO is more than 6 L/min, what should Treat sepsis, Treat fluid overload
the nurse do? HIGH=TOO MUCH blood
being pumped)
Central Venous Pressure measures preload
If Central Venous Pressure (CVP) is less Admin IVFs, Admin vasopressors
than 2, what should the nurse do -
LOW=DECREASED fluid)
If CVP is more than 6, what should the Admin vasodilators, Treat Heart failure
nurse do - HIGH=INCREASED fluid)
Systemic Venous Resistance (SVR) Afterload
measures
If SVR is less than 800, what should the Admin fluid bolus, Treat distributive shock, Admin vasopressors
nurse do - LOW=LOW PRESSURE in vessels
- vasodilation)
If SVR is more than 1200, what should the Admin vasodilator, Treat hypovolemia, Treat hypotension, Treat cardiogenic shock
nurse do? HIGH=HIGH PRESSURE in
vessels - vasoconstriction)
1. Deoxygenated blood from tissues enters right atrium, 2. Deoxygenated blood
Put the movement of blood within the heart
leaves right ventricle to lungs, 3. Oxygenated blood enters from lungs to left atrium,
in order, starting with deoxygenated blood
4. Oxygenated blood leaves the left ventricle to the tissues
Preload - volume of blood entering the heart during relaxation "diastole", Afterload -
Match the definitions in order of Preload,
amount of resistance to pump blood during contraction "systole", Cardiac Output -
Afterload, Cardiac Output
amount of blood pumped per heartbeat
A male pt reports an abrupt onset of MI - myocardial infarction
angina, shoulder pain, SOB, n/v,
diaphoresis, + fatigue. What is this?
There are atypical symptoms of an MI. List females - Abdominal pain, elderly - Confusion or Syncope, diabetic- Asymptomatic
in order what are symptoms for a female,
elderly, and diabetic?
The most common cause of an MI is a Family hx, Post-menopausal female, Male
dislodged plaque from atherosclerosis.
What are non-modifiable risk factors?
CAS is a term used for concern of an MI. Unstable Angina - Chest pain unrelieved with rest, unrelated to exercise, NSTEMI-
Match the definition in order of Unstable Partial occlusion of coronary artery, leading to partial thickness damage, STEMI -
Angina, NSTEMI, STEMI Complete occlusion of coronary artery, leading to full thickness damage
A major coronary artery block MI is JVD, Hypotension, Bradycardia
DEADLY. What are signs it is on the RIGHT
side?
What are signs of a coronary artery block Dyspnea, HTN, Tachycardia
on the LEFT side? This one is MORE
DEADLY)
When a pt shows symptoms of an MI, what Oxygen, Nitroglycerin, Aspirin, Morphine
should a nurse administer in order?
To ensure accurate hemodynamic values, Zero and calibrate in supine position, Secure transducer at phlebostatic axis at the
what MUST be done? 4th Intercostal space
If the transducer is TOO high, values will be LOW. If the transducer is TOO low, values will be HIGH
