    • The principle of justice requires that

    • The principle of justice is particularly
        relevant to critical care because most

        technology and pharmaceuticals, are
        expended in this practice setting.

 1. Rapid transit to the hospital.                        1.   Decreased cardiac output
 2. Obtain 12-lead ECG within 10 mins.                    2.   Activity intolerance
 3. Obtain laboratory blood specimens of cardiac          3.   Excess fluid volume
     biomarkers.                                          4.   Risk for impaired gas exchange
 4. Begin routine medical interventions.                  5.   Risk for impaired skin integrity
 5. Evaluate for indications for perfusion therapy.
 6. Bed rest for a minimum of 12-24 hours.                  CLASSIFICATION OF HEART FAILURE

  § Left ventricle cardiac output is less
  § Volume is received from pulmonary
     circulation..
  § Blood accumulated in the left ventricle, left
     atrium.
  § Pulmonary congestion forcing fluid from
     pulmonary capillaries into pulmonary tissue
     and alveoli causing pulmonary interstitial
     edema and impaired gas exchange.               Left Sided Heart Failure
      RIGH-SIDED HEART FAILURE
  § Right ventricle cardiac output is less.
  § Volume received from the peripheral
     venous circulation.
  § Blood accumulates in right atrium, right
     ventricle.
  § Increased venous pressure lead to JVD
     and increased capillary hydrostatic
     pressure through the venous system.

         o Severe rise in BUN and Creatinine

• High mortality rate but is related to clients being

     container. You will need to keep it cold.
2.   The 24-hour collection may start at any
     time during the day after you urinate. It is
     common to start the collection the first thing
     in the morning. It is important to collect all
     urine in the following 24-hour period.
3.   Instruct not to save the urine from first time
     urinating. Flush this first specimen but note
     the time. This is the start time of the 24-hour
     collection.
4.   All urine, after the first flushed specimen,
     must be saved, stored, and kept cold. This
     means keeping it either on ice or in a
     refrigerator for the next 24 hours.
5.   Once the urine collection has been
     completed, the urine containers need to be
     taken to the lab as soon as possible
