NURS 480 EXAM 2 QUESTIONS AND
ANSWERS VERIFIED AND WELL
DETAILED ANSWERS


atenolol - CORRECT ANSWER - lowers heart rate (heart beats slower) and with
|| || | || || || || || || || || ||


less force
|| ||




widens veins to lower blood pressure
| || || | |




usually given to patients with:
|| || || || ||




- atrial fibrillation ||




side effects:
||




- hypotension
- bradycardia
- dizziness


atropine - CORRECT ANSWER - increases heart rate and improves
|| || || || || || || || ||


atrioventricular conduction by blocking the parasympathetic influences on the
|| || || || || || || || ||


heart
||




initial treatment for:
|| ||




- symptomatic 3rd degree AV blocks | || | ||




- sinus bradycardia ||




- asystole


epinenphrine - CORRECT ANSWER - increases heart rate and effectiveness of
|| || | || || || || || || ||


the lungs, therefore increasing oxygenation
|| || || || ||




increases blood pressure & blood sugar || || || | ||




used for:
|| ||



- ventricular tachycardia |

,- ventricular fibrillation |




- asystole


warfarin - CORRECT ANSWER - oral anticoagulant used to treat and prevent
|| || | || || || || || || || ||


blood clots
|| ||




patients must understand the risks of bleeding & that they may bleed longer from
|| || || || || || || || || || || || ||


cuts
||




nitroglycerin - CORRECT ANSWER - vasodilator used to relieve chest pain
|| || | || || || || || || ||




side effect:
|| ||




- hypotension


morphine - CORRECT ANSWER - reserved for patients with:
| || | || || || || ||




- myocardial ischemia ||




side effects:
||




- respiratory depression |




- constipation


lisinopril - CORRECT ANSWER - ACE inhibitor used to treat high blood
|| || | || | || || || || || ||


pressure and heart failure
|| || || ||




education:
- take with food or milk
|| || || ||




- check pulse before taking || || ||




- report angioedema ||




- flushing of skin or persistent cough is normal || || || || || || ||




sinus tachycardia characteristics - CORRECT ANSWER - ventricular & atrial
| || || || | || || || ||


rate:
||

,- between 100-120 bpm | ||




ventricular & atrial rhythm: || || ||




- regular


QRS shape & duration:
|| || ||




- usually normal ||




P wave: |




- normal and consistent shape || || ||




- always in front of the QRS but may be buried in the T wave
|| || || || || || || || || || || || ||




PR interval: ||




- consistent interval between 0.12-0.20 seconds | || || |




P:QRS ratio: ||




- 1:1||




sinus tachycardia causes - CORRECTANSWER - stress
| || || || | || ||




- acute blood loss || ||




- anemia
- shock
- pain
- hyper/hypovolemia
meds that stimulate sympathetic response
| | | |




POTS syndrome
|| ||

, sinus tachycardia management - CORRECT ANSWER - vagal maneuvers
| || || || | || || ||




- carotid sinus massage || ||




- gagging
- bearing down (as if having a bowel movement)
|| || || || || || ||




- forceful and sustained coughing || || ||




- applying cold stimulus to the face || || || || ||




- administer adenosine |




- beta blocks & calcium channel blockers
|| || || || ||




- cardioversion


1st degree heart block causes - CORRECTANSWER - medications
|| || || || || || | || ||




- digitalis
- calcium channel blockers || ||




- betablockers|




Lyme disease
|| ||




myocardial ischemia/infarction |



hypothyroidism
||




increase in vagal tone || || ||




- long-term athletic training || |




- sleep
- coughing
- suctioning
- pressure above eyes || ||




1st degree heart block characteristics - CORRECT ANSWER - ventricular &
|| || || || || || | || || ||


atrial rate:
|| ||




- depends on underlying rhythm || || ||
