NUR 245 EXAM 3 - Notes
55 - Questions
Math: mL/hr. Units.
6 – Shocks
ARDS
Respiratory Failure or ARF
COPD
Ventilators
Chest Tube
Cardiogenic Shocks - causes – MI, cardiac tamponade. Decrease
blood flow to the heart.
1. What medications are given? Digoxin, Diuretic, dobutamine.
& Beta blockers. Treat the cause.
2. Why we give beta blockers to someone in cardiogenic
shock? To decrease heart rate. The beta blockers are your
fight and flight response that increases heart rate when
stimulated. This blocks.
3. Do you want to give fluids to cardiogenic patients? No,
because they have too much already. Pressure will be high.
4. If someone has ventricular septal defect – a hole between
ventricles and blood is moving from right side of the heart to
the left side. It is not going to the lungs or the body.
5. Treatment. First oxygen but if the oxygen is not working
(Low SpO2), what will you do next? Intubated and
mechanical ventilator.
Hypovolemic Shock – Absolute you’re losing fluid out of your
body VS. relative you’re losing fluid vascular tissues leaking out
of that space (most famous is BURNS) - Fix the Cause
6. A patient who lost a lot of blood or fluid like in hypovolemic
shock and the BP is very low. What will you do first for that
patient? Start an IV & give IV fluids.
7. Patient’s BP 74/48 and get 1000 mL NS Bolus over an hour
and their blood pressure goes up to 88/60. So, we might have
to consider starting some Vasopressor on continuous IV

, drips patient will be ICU. A lot of fluid at an hour and
Change MAP above 65 or systolic 90? What will you do
with dopamine drip? Titrate it. Turn it off.
8. What do you think it is important to monitor
Norepinephrine? Blowing it into the extremities. Monitor the
circulation. Cannot take it more than 2 weeks.
9. Bowtie Question? What kind of parameters will the nurse
evaluate to check if fluid or dopamine drip is effective? BP
& MAP ≥65.
10. How do you know if treatment was effective or not? Urine
output and Central venous pressure (CVP).
Septic Shock
11. Who is at risk? (Pick patient with any kind of infections)
• UTI
• Wound
• GI (peritonitis),
• Lung (pneumonia);
• Lines (IV, drains, ICP, CTs, ETTs)
• Catheters
• invasive procedures: Surgeries
o D/C catheters & Lines using Aseptic or Sterile
Technique
12. How long should it take you to start antibiotics? Within one
(1) hour one hour
13. what causes vasodilation in septic shock? Massive
inflammatory response And Toxin from bacteria.
14. What is the first thing we do for this patient? Give IV
fluids.
15. A patient that is in septic shock if they have a MAP above
65, dissent BP or stable BP. What will you do? Need culture
done and start broad- spectrum ATB within 1 hour.
16. If your questions give you BP or MAP that is not
