The registered nurse working in the cardiac care clinic is tasked with implementing quality improvement measures. To educate the clinic staff, the nurse plans an in-service program to introduce concepts of quality improvement and evidence-based practice. Additionally, the role of the case manager will be included in the presentation.

QUESTION 3: Case Study, Chapter 3, Critical Thinking, Ethical Decision Making, and the Nursing Process

1. Mrs. Elle, 80 years of age, is a female patient who is diagnosed with end-stage cancer of the small intestine. She is currently receiving comfort measures only in hospice. She has gangrene of her right foot and has a history of diabetes controlled with oral agents. She is confused and the physician has determined that she is unable to make her own informed decisions. The hospice nurse, not realizing that the weekly order for CBC and renal profile had been discontinued, obtained the labs and sent them to the nearby laboratory for processing. The abnormal lab results obtained later that day revealed that the patient needed a blood transfusion. The hospice nurse updated the patient’s medical power of attorney who was distressed at the report. The patient’s wishes were to die peacefully and to not have to undergo an amputation of her right foot. But if the patient receives the blood transfusion, she may live long enough to need the amputation. The patient’s physician had previously informed the medical power of attorney that the patient would most likely not be able to survive the amputation. The patient’s medical power of attorney had made the request to cease all labs so that the patient would receive comfort measures until she died. The patient has no complaint of shortness of breath or discomfort. (Learning Objective 4)

Adam Smith, 77 years of age, is a male patient who was admitted from a nursing home to the intensive care unit with septic shock secondary to urosepsis. The patient has a Foley catheter in place from the nursing home with cloudy greenish, yellow-colored urine with sediments. The nurse removes the catheter after obtaining a urine culture and replaces it with a condom catheter attached to a drainage bag since the patient has a history of urinary and bowel incontinence. The patient is confused, afebrile, and hypotensive with a blood pressure of 82/44 mm Hg. His respiratory rate is 28 breaths/min and the pulse oximeter reading is at 88% room air, so the physician ordered 2 to 4 L of oxygen per nasal cannula titrated to keep SaO2 greater than 90%. The patient responded to 2 L of oxygen per nasal cannula with a SaO2 of 92%. The patient has diarrhea. His blood glucose level is elevated at 160 mg/dL. The white blood count is 15,000 and the C-reactive protein, a marker for inflammation, is elevated. The patient is being treated with broad-spectrum antibiotics and norepinephrine (Levophed) beginning at 2 mcg/min and titrated to keep systolic blood pressure greater than 100 mm Hg. A subclavian triple lumen catheter was inserted and verified by chest x-ray for correct placement.

Joe Clark, 79 years of age, is a male patient who is receiving hospice care for his terminal illnesses that include lung cancer and chronic obstructive pulmonary disease (COPD).

He states that he is short of breath and feels anxious that the next breath will be his last. The patient is admitted to the hospital for a thoracentesis (an invasive procedure used to drain the fluid from the pleural space so the lung can expand). The thoracentesis is being used as a palliative measure to relieve the discomfort he is experiencing. Low dose morphine is ordered to provide relief from dyspnea or discomfort. The patient is prescribed Proventil (albuterol) inhaler 2 puffs per day, as needed, and Flovent (fluticasone propionate) inhaler 2 puffs twice a day.
