Q

Nursing Process:

A

A-assess- gather info about the pts condition
4Ps- pain, personal needs, position, possessions
D- diagnose (analyze)- identify pts problems, causes, symptoms
P-plan- set goals of care and desires outcomes and identify appropriate nursing actions
ABCs, safety, maslow
I- implement- perform the nursing actions identified in planning
bases on clinical judgment and knowledge
types of interventions: nurse initiated, HCP initiated, collaborative
E- evaluate- determine if goals and expected outcomes are achieved

  • small frequent high calorie soft diet, rest 30 min before, give bronchodilator 1 hr before and after before meals
  • start oxygen low and slowly titrate up
  • Oxygen 88-90% (respiratory drive goes down and they become dependent)

EKG
PR: 0.12-0.20 sec QRS: 0.06-0.11 QT: 0.36-0.44 P Wave: impulse across the atria PR Interval: Beginning of P wave to beginning of QRS QRS Complex: Impulse through bundle branches & into Purkinje fibers, ventricular depolarization ST Segment: From end of QRS to beginning of T wave T Wave: ventricular depolarization, rounded, larger than P wave QR interval: Measures from beginning of QRS to end of the T wave.
31
7 steps to Rhythm Interpretation
1. Identify P wave, QRS complex, & T wave. - Is there a P for every QRS? - Are all the complexes consistent? 2. Determine if rhythm is regular or irregular? 3. What is the rate? - 6 second method: count number of complexes and multiply by 10= HR in bpm - Can be used for regular and irregular rhythms 4. Measure the PR interval. - Normal PR 0.12-0.20 seconds (3-5 small boxes) 5. Measure the QRS complex. - Normal QRS is less than 0.12 seconds (less than 3 small boxes) 6. Measure the QT interval - Normal QT is 0.36 – 0.44 seconds 7. Name the rhythm. - Where is the impulse generated? Sinus, Atrial, Junctional, Ventricular - What is the rate? Normal, Brady-, Accelerated, Tachy- - Are there any additional abnormal characteristics noted?
