A 62-year-old patient taking aspirin daily for cardiovascular protection calls the clinic complaining of a “ringing in the ears” that started yesterday and has not improved. What should the clinician suspect as the most likely cause?

A patient with GERD and delayed gastric emptying is prescribed metoclopramide. He asks how this medication will help his symptoms. Which explanation best describes metoclopramide’s mechanism of action in GERD management?

Contracts are legally enforceable agreements.

Courts can create quasi contracts where they did not exist before.

Once an offer is made, it cannot be revoked.

Courts will enforce contracts that have an illegal purpose. 

Minors may create contracts.

 If the contract is based on a fundamental factual error by both parties, the contract is voidable by either one.

Which of the following physiological metrics is most commonly used to assess physical workload? 

Answer the following questions True (T) or False (F): ___  If a sequence is separable, each row is a multiple of every other row, and each column is a multiple of every other column. ___  A necessary condition for linearity is that the output doubles when the input doubles. ___  Linearity of a system implies that its response to an arbitrary input can be computed using the convolution sum.   ___  The Fourier transform of any rotated version of the original function is just the rotated Fourier transform. ___  If a signal is not band limited, then a lowpass filter can be employed prior to sampling to eliminate aliasing. ___  Hexagonal sampling always results in 13.4% fewer samples than rectangular sampling. ___  The difference equation specifying an IIR filter gives all the necessary information required to implement the filter. ___  To compute the inverse Z-transform, a 2-D polynomial is usually factored as a product of lower-order polynomials. ___  For Z-transforms, a system is stable if and only if the ROC includes . ___  The DFT coefficients are samples of the DSFT at hexagonally sampled points.
