NUR 325 Final 11. The degree of stretch at the end of diastole (how much blood is in the ventricles) is known
as
Answer
Preload
2. An increase in fluids will preload, and a decrease in fluids will
preload
Answer
An increase in fluids will increase preload, and a decrease in fluids will decrease preload
3. The resistance to eject blood from the ventricles is known as
Answer
Afterload
4. Hypertension and vasoconstriction have what effect on Afterload?
Answer
HTN and vasoconstriction will INCREASE afterload (increased afterload raises cardiac
workload as well)
5. How effectively the heart can squeeze out blood is also known as
Answer
Contrac- tility
6. How are preload and contractility related?
Answer
Optimal filling allows for maximum stretching
7. What could the nurse give a patient to increase their contractility?
,Answer
Epineph- rine, Digoxin, Dopamine
8. What could the nurse give a patient to decrease their contractility?
Answer
-
Beta-blocker (the "lol" meds)
9. What are the life-threatening dysrhythmias?
Answer
V Tach, V Fib, and Asystole
10. What is the first thing the nurse should do if they see a life threatening rhythm on a
patient's EKG?
Answer
Assess the patient (Did a lead fall off? Does the patient show signs of decreased CO? Are they
responsive? Pulses?)
11. The patient is in V Tach but has a pulse, how can we treat this?
Answer
We give amiodarone and use cardioversion (because they have a pulse)
12. The patient is in V Tach but does NOT have a pulse, how do we treat this?
Answer
CPR and Defibrillation
13. The patient is in V Fib, what do we do?
Answer
CPR/ACLS, Defibrillate, Drug therapy
14. What drugs can we give to a patient in V Fib?
Answer
,Epinephrine, Amiodarone
15. I can defibrillate the patient if they have what dysrhythmias?
Answer
Pulseless V Tach, and V Fib
16. The patient is a candidate for Synchronized Cardioversion if they have what dysrhythmias?
Answer
V Tach (WITH A PULSE), SVT, A Fib, and A Flutter
17. The patient is asystolic, what do you do?
Answer
CPR/ACLS, drug therapy, intubate
18. What drugs do we give if the patient is in asystole?
Answer
Epinephrine and/or vasopressin
19. The patient shows activity on their EKG but has no pulse, this is known as
Answer
Pulseless Electrical Activity (PEA)
20. The patient has a normal heart rate, but the PR interval is longer than normal. What
dysrhythmia do you suspect the patient has?
Answer
1st Degree AV Block
21. You notice a gradual lengthening in the patient's PR intervals and a miss- ing QRS wave.
Whatdysrhythmia do you suspect the patient has?
Answer
2nd Degree AV Block Type 1
, (Mobitz I // Wenckebach)
22. The patient has constant elongated PR intervals and P waves at a regular rate, but missing
QRS complexes. What dysrhythmia do you suspect?
Answer
2nd Degree AV Block Type 2
(Mobitz II)
23. You notice the patient has consistent P waves and QRS complexes, but the rates between the
two are different (Some P waves do not have a QRS after).
What dysrhythmia do you suspect?
Answer
3rd Degree AV Heart Block (Complete Heart Block)
24. The main cause of CAD, characterized by fat deposits in the arteries
Answer
Atherosclerosis
25. What are some modifiable risk factors for CAD?
Answer
Lipid levels, HTN, smoking, obesity, inactivity
26. This cholesterol transports lipids to the liver for removal, known as the "good cholesterol"
Answer
High Density Lipoprotein (HDL)
27. This cholesterol transports lipids to the arterial vessels, known as the "bad cholesterol"
Answer
Low Density Lipoprotein (LDL)
28. A serum cholesterol of indicates a risk factor for CAD
