NURS 3525 Exam 3: Cardiac Rhythms and Gastrointestinal Disorders, Exams of Nursing

A comprehensive overview of various cardiac rhythms, including normal sinus rhythm, sinus bradycardia, sinus tachycardia, paroxysmal supraventricular tachycardia (svt), atrial flutter, atrial fibrillation, junctional rhythm, junctional tachycardia, idioventricular rhythm, premature ventricular contraction (pvc), ventricular tachycardia (vt), ventricular fibrillation (vf), and ventricular standstill (asystole). It also covers gastrointestinal disorders such as nausea, gerd, hiatal hernia, peptic ulcer disease (pud), gastritis, diarrhea, c.diff, fecal incontinence, and constipation. Detailed descriptions of each condition, their causes, symptoms, diagnostics, management, and nursing care considerations.

NURS 3525- Exam 3 Combined With Verified Solutions

Normal sinus rhythm (NSR)

  1. pulse present
  2. regular rhythm
  3. rate 60 - 100
  4. P waves: upright, rounded, 1 for every QRS complex
  5. PR interval: ≤ 0.20 seconds
  6. QRS complex: ≤ 0.12 seconds Sinus Bradycardia
  7. pulse present
  8. regular rhythm
  9. rate: < 60 bpm
  10. P waves: upright, rounded, 1 for each QRS complex
  11. PR interval: ≤ 0.20 seconds
  12. QRS complex: ≤ 0.12 seconds Sinus tachycardia
  13. pulse present
  14. regular rhythm
  15. rate: 101 - 180 bpm
  16. P waves: upright, rounded, 1 for each QRS complex
  17. PR interval: ≤ 0.20 seconds
  1. QRS complex: ≤ 0.12 seconds paroxysmal supraventricular tachycardia (SVT)
  2. pulse present
  3. regular or slightly irregular rhythm
  4. rate: 151 - 220 bpm
  5. P waves: distorted shape or hidden in T-wave
  6. PR interval: ≤0.20 seconds
  7. QRS complex: ≤0.12 seconds Premature Arterial contraction (PAC)
  • ectopic beat
  • not a rhythm (must identify underlying rhythm)
  • rate: can be irregular
  • P waves in PAC will appear differently than other P waves on strip
  • PAC is followed by period of delay in electrical activity Atrial flutter ABNORMAL RHYTHMS Atrial Flutter

rate: 61 - 100 idioventricular rhythm

  1. pulse is present
  2. rhythm regular
  3. rate 20 - 50 bpm (accelerated rate 51 - 100)
  4. P waves absent
  5. PR interval: N/A
  6. QRS complex: wide >0.12 seconds premature ventricular contraction (PVC)nectopic beat is not a rhythm no P wave QRS > or = 0. followed by pause unifocal vs multifocal Ventricular tachycardia (VT) runs of 3 or more PVCs!! rate: 150 - 250 Wide QRS complex TX: CPR, defibrillation Ventricular fibrillation (VF) ventricle is quivering rate: unable to measure QRS: unable to measure

TX: CPR, Defibrillation Ventricular Standstill (Asystole)

  • no electrical activity in the ventricle
  • death will quickly occur if the arrhythmia is not reversed TX: CPR/Meds (very hard to treat with success) Pulseless electrical activity (PEA)
  • mechanical heart activity is absent but there is electrical activity visible on the EKG
  • patient DOES NOT HAVE A PULSE GI problem may present as nausea illnesses caused by nausea dehydration, electrolyte imbalance, metabolic alkalosis treat the nausea identify underlying cause and treat complications assessment for nausea precipitating factors, emesis contents, timing common predicating factors with nausea pregnancy, brain injury, gallbladder issues, MI, medications, motion sickness types of emesis content bright bed color, coffee ground like, partially digested food positioning for pt who cannot move independently with nausea side lying or high fowlers
