The nurse is caring for a client who has an arteriovenous (AV) fistula placed in the left arm after a diagnosis of end stage renal disease. The nurse plans care recognizing that?

A client is discharged after passing a kidney stone. This is the third hospitalization for kidney stones. What should the nurse teach the client?

The nurse develops the nursing diagnosis of “Unilateral Neglect related to sensory-perceptual deficits” for a client with a right hemisphere stroke. Which intervention should the nurse include in the client’s plan of care?

The nurse recognizes that a priority intervention when caring for a client during the acute phase of a stroke is?

The nurse recognizes that which type of stroke would be contraindicated to receive IV fibrinolytic therapy?

The nurse is preparing to administer the 0800 dose of Phenobarbital (Dilantin) to a 4 year old client.  The order reads: Give Phenobarbital (Dilantin) 45 mg two times a day by mouth.  How much Phenobarbital (Dilantin) will the nurse prepare from the 20mg/5ml suspension bottle?

One area of concern with the binomial model and our solutions is that options have negative vegas (i.e., as we increase the underlying’s volatility in our model, option prices fall).

Challenge When considering the option greeks, we saw that, while the BSOPM had explicit formulas for all of the greeks, the BINOM only had a formula for one: the delta. In this challenge, we will compare the two and see that the BINOM approximation for shorter expirations is actually quite similar to the BSOPM delta! Myron and Stephen are each pricing a three-day option. Myron uses the BSOPM while Stephen uses a three-period BINOM with the CRR solutions (see equation sheet). They agree that annualized volatility of the stock’s log returns 70 percent for a stock whose spot price is $26.50. The current annualized continuously compounded risk-free rate is 5 percent. What is the percentage difference between Myron’s (BSOPM) delta estimate and Stephen’s (BINOM) delta estimate for the $27-strike call? Enter your answers as a percentage, rounded to the nearest 0.001%. For example, for 0.123456, enter 12.346. Enter your answer as a positive number.

You build a three-step binomial model to price a call on a stock whose spot price is currently $[S]. The strike price of the option is $[K] and your estimate of the gross risk-free rate in simple terms is 1.000[R0]. You price the put at $[P]. What is your price for the otherwise identical call? Enter your answer as a number of dollars, rounded to the nearest $0.01. For example, for $12.3456, enter $12.35.
