In a two-dimensional graph where the X-axis is Risk (Standard Deviation) and the Y-axis is Reward (Expected Return), which of the following logical conclusions can be drawn? I. The “Efficient Frontier” represents the set of portfolios that offer the highest possible Y-value for any given X-value.II. A line drawn from the Risk-Free rate through a portfolio point has a slope equal to that portfolio’s Sharpe Ratio.III. The Madoff fund’s reported performance would plot as a point significantly above the established Efficient Frontier of liquid markets.IV. To achieve a better risk-reward trade-off, an investor should seek to decrease the “slope” of their portfolio’s position relative to the origin.

68. Which assessment finding in a patient with a tibial fracture would most concern the nurse for developing fat embolism syndrome?

92. A patient in status epilepticus has an order for lorazepam (Ativan) 2 mg IV push. The pharmacy supplies lorazepam 4 mg/mL. How many mL will the nurse administer?

Again for the graph.  Which of the following statements correctly describe the financial logic?   I. The Madoff fund is intuitively attractive to investors because its path exhibits high “persistence” with minimal drawdowns, suggesting a superior risk-reward trade-off.II. The Sharpe Ratio formalizes this intuition by dividing the excess return by the standard deviation of those returns.III. A single volatile stock with the same ending return as the Madoff fund would have a higher Sharpe Ratio due to its higher variance.IV. Visual “smoothness” in a cumulative return plot is a direct proxy for the denominator in the Sharpe Ratio calculation.

33. A patient with myasthenia gravis who takes pyridostigmine (Mestinon) reports increased muscle weakness, excessive salivation, and abdominal cramping. The nurse suspects:

55. A 70-kg patient with 40% TBSA burns arrives 1 hour after injury. Using the Parkland formula, what is the total volume of Lactated Ringer’s for the first 24 hours?

91. A patient in anaphylaxis requires epinephrine 0.5 mg IM. The available concentration is 1 mg/mL (1:1000). How many mL will the nurse administer?

72. A patient one day after posterior lumbar fusion develops new bilateral leg weakness and loss of bladder control. The nurse recognizes this as a potential:

71. A patient 6 hours post-ORIF of the tibia reports severe pain rated 10/10 that is unrelieved by IV morphine. The nurse’s most important action is to:

47. A patient reports seeing flashing lights, a sudden shower of floaters, and a ‘dark shadow’ starting at the edges of vision in the left eye. Which action is most appropriate?
