NUR 325 Final Exam Practice Questions and Answers (100% pass)
What is stenosis? - ✔️✔️Stiffening or narrowing of the valve, really hard for the blood to
make its way through the valve
What is regurgitation? - ✔️✔️The valve doesn't close completely and blood can go back
through the valve the opposite way; valve becomes a two way door
What does regurgitation cause? - ✔️✔️A murmur
What is Preload? - ✔️✔️The amount of stretch on the ventricles at the end of diastole
How can preload be measured? - ✔️✔️Central Venous Pressure, Stroke volume (The
amount of blood the ventricles contracts/shoots out), Passive Leg Raise
Passive leg raise to measure preload - ✔️✔️If stroke volume increases by more than 10%
when legs are raised above the head, could benefit from more fluids
Ways to improve a low preload - ✔️✔️Fluids
Ways to improve a high preload - ✔️✔️Diuretics or dialysis in the case of kidney failure
Physical Assessment of Low Preload - ✔️✔️Hypovolemic so dry skin, dry mucus
membranes, low skin turgor, orthostatic

Physical Assessment of High Preload - ✔️✔️Hypervolemic so edema, crackles on lungs,
hypoxic, SOB, weaping
What is Afterload? - ✔️✔️The amount of resistance the ventricles have to face at the end
of systole
How to measure Afterload - ✔️✔️SVR (Systemic Vascular Resistance): how
dilated/constricted blood vessels are
How to improve a low Afterload - ✔️✔️Vasopressin, dopamine (high doses),
norepinephrine, epinephrine
How to improve a high Afterload - ✔️✔️Nitroglycerin, Nicardipine, Labetelol
What is contractility? - ✔️✔️How the heart is squeezing
Ways to Measure Contractility - ✔️✔️Cardiac output, cardiac index (more individualized)
Ways to improve Contractility - ✔️✔️Epinephrine, dopamine and dobutamine, digoxin
What are example of invasive lines? - ✔️✔️Peripheral lines, Arterial lines, Central Venous
Catheter, and Pulmonary Artery line
How to care for a Arterial Line? - ✔️✔️Give fluids so that the line doesn't clot off, Make
sure to watch distally to the insertion sight, Insertion sight always staying covered,

Transducer needs to be level to fourth intercostal space midaxillary line (heart) and the
level needs to be 0
What if a transducer is too low? - ✔️✔️Artificially too high of a BP
What if a transducer is too high? - ✔️✔️Artificially too low of a BP
How to care for a Peripheral Line? - ✔️✔️Check for infiltration, redness and swelling at
the sight, Check for infection
How to care for a Central Venous Catheter? - ✔️✔️Inserting sterile and keeping a sterile
dressing over it, Clean off ports before you give medication, Green caps that are full of
alcohol to keep the ports clean when they aren't being used, Flush every 8 hours, CHG
bath, bath every day in general
How to care for a Pulmonary Arterial Line? - ✔️✔️Similar to Central Lines
Normal Sinus - ✔️✔️PR interval 0.20, QRS interval less than .11, Rate is 60-100
Sinus Bradycardia - ✔️✔️PR interval 0.20, QRS interval less than .11, Rate is less than
60
Sinus Brady Symptoms - ✔️✔️o Decreased level of consciousness
o Decreased capillary refill
o Lightheaded, dizzy

o Cool, clammy skin
o Fatigue
How to treat sinus brady? - ✔️✔️Give Atropine, Epinephrine, Dopamine
Sinus Tachycardia - ✔️✔️PR interval 0.20, QRS interval less than .11, Rate is over 100
Symptoms of Sinus Tachy - ✔️✔️Similar to Bradycardia
How to treat Sinus Tachycardia - ✔️✔️- Treat underlying cause like pain, anxiety, stress
- Beta blockers
SVT (Supraventricular Tachycardia) - ✔️✔️QRS interval is less than .11, no ST elevation,
Very high rate, cannot measure PR interval
How to treat SVT - ✔️✔️Vasovagal Maneuvers (blow into a straw, cough, bear down),
Adenosine, Betablockers or calcium channel blockers, and cardioversion
What vasovagal maneuver can only a physician do? - ✔️✔️Carotid Massage
Symptoms of SVT - ✔️✔️-palpitations
-SOB
-dizziness
-syncope
