An APRN treating a patient with anxiety related to heights initially recommends ___________________________to facilitate fear extinction. 

A new patient being seen for symptoms of depressed mood also complains of extreme fatigue, widespread pain across many of her muscles and joints, and never feeling like she had a “good night’s sleep” despite often sleeping 10-12 hours at night. Upon assessment, she complains of tenderness at numerous points where ligaments, tendons and muscles attach to bone. Which of the following would be the least appropriate treatment option?

An initial evaluation of a 32 year old female by an APRN reveals criteria is met for a major depressive episode, and a great deal of worry and difficulty concentrating are interfering with functioning. The patient has not previously taken psychotropic medications. Which one of the following medications is most appropriate according to FDA guidelines for the APRN to prescribe? 

Which area within the central nervous system is a main target of medications being used to relieve pain due because of the numerous neurotransmitters and neurons present?

Two 4-point  FFTs and a 4-point  IFFT  are used to perform fast convolution of the sequences x(n) and h(n) (N = 4) h(n) =4δ(n) + 6δ(n-1) +2δ(n-2) +7δ(n-3) x(n) =u(n) – u(n-4) The result y(n) for n=1,2,3,4  after the IFFT is equal to

A N-point DFT (N=16) requires N2 complex multiplications. If this N-point DFT is performed by combining the results of two (N/2)-point DFTs, the number of complex multiplications required is:

Give the steady state response of the causal filter H(z) to the input x(n)=3 sin(πn/6) H(z) = 2 + 2z-6 The steady-state response of H(z) is:

For the signal x(n) shown below,  determine the value of the following DFT sum function for N=128 without computing explicitly the DFT sum. x(n) = δ(n) + 2δ(n-1) – 9δ(n-12) + 13δ(n-50)

Give the expression for the ideal impulse response of a bandstop filter with cutoff frequencies at 5 kHz and 7.5 kHz. The sampling frequency is 30 kHz.

A line is written in Standard Form: 4x – 2y + 12 = 0. Convert this equation to Slope-Intercept form (y = mx + b) to identify the slope and y-intercept.
