41. The nurse has just completed administration of a 1000-L bolus of 0.9% normal saline. The nurse assesses the patient to be slightly confused, with a mean arterial blood pressure (MAP) of 50 mm Hg, a heart rate of 110 beats/min, urine output of 10 mL for the past hour, and a central venous pressure (CVP/RAP 1-8 mmHg) of 2 mm Hg. What is the best interpretation of these results by the nurse?

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 The intensive care team suggest that treatment should be withdrawn as her chances of survival are remote, but the hematologists argue that her renal, respiratory, and cardiovascular failure are potentially reversible if the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 After discussion with the family it is agreed that treatment should be withdrawn on the grounds of futility.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.

The (1)___________(a. PC1, b. PC2) captures the largest variance in the sample data. The (2)___________(a. PC1, b. PC2) captures the second largest variance in the sample data. The direction of PC2 is orthogonal to PC1. PC1 and PC2 are (3)___________(a. correlated, b. uncorrelated).
