Nursing Assignment Help




John Thomas is a 64-year-old Caucasian male who presents to the emergency room with a two-day history of intermittent substernal chest pressure associated with shortness of breath and diaphoresis.  The pain had originally awoken Mr. Thomas from sleep 2 nights ago and has been intermittently relieved with some sublingual nitroglycerin tablets that he had received from his physician 3 years ago.  The pain increases with exertion, but now is constant.  He rates the pain a “7” on a scale of 1 to 10.

Critical thinking exercises

  1. List your primary medical and nursing diagnoses for this patient.
  2. What area of the left ventricle is affected by this MI?
  3. What is your rationale for EACH of the abnormal physical assessment parameters, the abnormal laboratory results, and the abnormal diagnostic tests?
  4. What are your anticipated nursing interventions for this patient?






Mr. Thomas is admitted to the CCU with a diagnosis of Acute MI with congestive heart failure.  The following orders are obtained:

Vital Signs q1h

Continuous ECG monitor


Foley catheter

Nitroglycerin IV infusion @ 10 mcg/min

Heparin IV infusion @ 1000 units/hr

PTT q6h and call results if <60 or > 90

CK isoenzymes q8h x3

Troponin level q12h x2

O2 at 2 1iters/min per NC—titrate for SpO2>91%

Lopressor 25 mg PO BID

Ambien 5 mg PO qHS PRN sleep



  1. What is your rationale for each of the admitting orders?





Mr. Thomas’ urine output decreases to 10 ml/hr and is unresponsive to a dose of IV Lasix.  He complains of increased SOB and physical exam reveals increasing rales bilaterally.  A pulmonary artery catheter is inserted with the following parameters obtained:


CVP= 10         PCWP=22       PA pressure=38/20

CO=  4.1         CI=1.9             SVR=1872




  1. What is the reason for each of the above parameters and what medication do you anticipate starting?




You had provided Mr. Thomas with some IV morphine sulfate for pain.  You check on him 30 minutes later and find that he is unresponsive with slow, shallow respirations.  He is diaphoretic.  An ABG on 2L/NC reveals:


pH=7.22          pCO2=50         pO2=82            HCO3=26        SaO2=83%



  1. What does the ABG reveal?
  2. What is the probable cause?
  3. What are the anticipated medical and nursing interventions?
