The use of real-life examples primarily serves to:

45. The nurse is caring for a patient diagnosed with severe sepsis who was resuscitated with 3000 mL of lactated Ringer solution over the past 4 hours. Morning laboratory results show a hemoglobin of 8 g/dL and hematocrit of 28%. What is the best interpretation of these findings by the nurse?

40. While monitoring a patient for signs of shock, the nurse understands which system assessment to be of priority?

______ can be defined as full awareness with one’s own internal mental processes in a nonconfrontational, nonjudgmental, detached way, which often involves a reduction in ______.

The loss function for the binary classification in an artificial neural network (ANN) is (1)______. The loss function for the multi-class classification in an artificial neural network (ANN) is (2)._______. The loss function for the regression in an artificial neural network (ANN) is (3)._____.

37. The nurse has just completed an infusion of a 1000 mL bolus of 0.9% normal saline in a patient with severe sepsis. One hour later, which laboratory result requires immediate nursing action?

An economist predicts consumer choice between banana (1), apple (2), and cheese (3) using two input features through the above artificial neural network. Based on the above figure, if the output of the softmax function for each class in the output layer are, 0.1 for banana, 0.2 for apple, and 0.7 for cheese, the consumer will purchase (1)____________ (a. banana, b. apple c. cheese; 2 points). This example is a case of (2) ___________ (a. regression, b. binary classification, c. multi-class classification; 2 points). Here, the output of the softmax function in the output layer is the probability of y, where y  

44. The nurse is caring for a patient admitted with the early stages of septic shock. The nurse assesses the patient to be tachypneic, with a respiratory rate of 32 breaths/min. Arterial blood gas values assessed on admission are pH 7.50, CO2 28 mm Hg, HCO3 26. Which diagnostic study result reviewed by the nurse indicates progression of the shock state?

43. The nurse is caring for a mechanically ventilated patient following insertion of a left subclavian central venous catheter (CVC). What action by the nurse best protects against the development of a central line–associated bloodstream infection (CLABSI)?

47. An 18-year-old patient has chemotherapy and bone marrow transplantation for leukemia. While waiting for marrow recovery she develops respiratory failure and needs mechanical ventilation with 100% oxygen. Shortly after she requires increasing doses of noradrenaline and progresses to renal failure. The intensive care team suggest that treatment should be withdrawn as her chances of survival are remote, but the hematologists argue that her renal, respiratory, and cardiovascular failure are potentially reversible if the bone marrow is given time to recover. After discussion with the family it is agreed that treatment should be withdrawn on the grounds of futility. You are the primary nurse involved in this case what will you do? Select all that apply.
