Cardiac Practice Qs Flashcards
1
Q
- Pt is admitted to ED with chest pain consistent with MI based on elevated troponin. Heart sounds are normal. Pulse has been increasing and is now 118, RR increased to 32, BP has now decreased to 88/58. What are these findings consistent with?
- Cardiogenic shock
- Cardiac tamponade
- PE
- TAA
A
- Classic signs of cariogenic shock are hypotension, rapid pulse that is weakening, decreased UOP, cool/clammy skin, increased RR due to metabolic acidosis.
2
Q
- Pt is sinus Brady with HR of 45, dizziness, BP 82/60. Which prescription should the nurse anticipate?
- Digoxin
- Defibrillate
- Continue to monitor
- Prepare for transcutaneous pacing
A
- Transuctaenous pacing will cause a temporary increase in the symptomatic client
3
Q
- Pt with MI is developing cariogenic shock. Because of the risk of myocardial ischemia, what should RN carefully assess for?
- Bradycardia
- Ventricular dysrhythmias
- Rising diastolic
- Falling CVP
A
- Dysrhythmias commonly occur as a result of tissue ischemia
4
Q
- RN is watching the cardiac monitor and rhythm suddenly changes. No P waves, wide QRS, ventricular rate is regular but > 140 bpm.
- Sinus tach
- Vfib
- VTach
- PVC
A
- V tach is characterized by the absence of P waves, wide QRS, and rate 140-180
5
Q
- Client has frequent bursts of V tach. What should the nurse be most concerned about?
- It can turn into vfib
- Almost impossible to convert to NSR
- Uncomfortable for the client
- Produces high cardiac output that leads to cerebral and myocardial ischemia
A
1.
6
Q
- What should the RN place priority on for frequent PVCs?
- sensation of palpitations
- causative factors such as caffeine
- BP and O2 sat
- Precipating factors such as infection
A
- PVCs can cause hemodynamic compromise due to shortened filling time.
7
Q
- Client has developed Afib, with ventricular rate of 150. Assess for which ssx?
- Flat neck veins
- Nausea vomiting
- hypotension, dizziness
- HTN and headache
A
- uncontrolled Afib with increased v. rate is at risk for low cardiac output
8
Q
- There are no P waves. Fibrillatory waves before each QRS complex. How should the RN interpret this?
- Afib
- Sinus tach
- Vfib
- Vtach
A
- Afib is characterized by loss of P waves and fibrillary waves before each QRS. The quiver can lead to thrombus formation
9
Q
- Which assessment is priority to evaluate response to cardioversion
- BP
- Airway
- Oxygen flow rate
- LOC
A
- ABCs
10
Q
- EKG shows rate 110, PR 0.14 seconds, QRS 0.08, regular. How should this be interpreted?
- sinus tach
- sinus Brady
- sinus arrhythmia
- NSR
A
1
11
Q
- The RN notes that a pt with sinus rhythm has a PVC that falls on the T wave of the preceding beat. Rhythm suddenly changes to no P waves, no QRS, and coarse wavy lines of varying amplitude.
- Asystole
- Afib
- VFib
- Vtach
A
3.
12
Q
- Which findings are digoxin toxicity? SATA
- Tremors
- diarrhea
- irritability
- Blurred vision
- N|V
A
