ISYE 6402 PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS GRADED A+
◍ Consider the arrival of a customer in a queueing system simulation. What
can (possibly) happen to the future events list (FEL) at this point?.
Answer: . All of the above.
◍ Role stress.
Answer: a situation of increased role; performance demand
◍ Entrepreneurship activity.
Answer: One who identifies a patients needs and envisions how nursing can
respond to that need in an effective way - then formulates and executes a
plan to meet that need
◍ Suppose thatU Unif(0,1).Then−1αln(1−U)and−1αln(U)have the same
distribution.Suppose thatU Unif(0,1).Then−1αln(1−U)and−1αln(U)have
the same distribution..
Answer: True
◍ What are the 3 quality of care dimension structures the 2005 donabedian
model encompasses?.
Answer: 1. Structure: the care delivery context (hospital, health care staff,
cost & equipment)2. Process: involve the actions taken in the delivery of
health care3. Outcomes: the effect of the care on the pt populations; often
viewed as the key quality indicator of care delivery
◍ Secondary care settings.
Answer: -Hospitals-Surgical Centers
◍ What CPT codes are for new or established pts for initial hospital inpatient
care services.
Answer: 99221-99223
,◍ Consider a single-server queue simulation with i.i.d. exponential
interarrivals, i.i.d. exponential services, and a first-in-first-out service
discipline. Suppose that the arrival rate is 5 per hour, and the service rate is
4 per hour. What will happen in the long run?.
Answer: b) The server will be busy all of the time.
◍ What is the purpose of ICD10 codes.
Answer: For documentation and billing diagnosis and procedures as well as
documenting cause of mortality from death certificats
◍ True or False ? Discrete-event simulations are particularly suitable for
analyzing continuous-flow phenomena such as the velocity and altitude of
an aircraft as it comes in for a landing..
Answer: False
◍ What is the purpose of medicare part A.
Answer: Provides inpatient hospital coverage (Hospital, skilled nursing
facility, hospice, some home health)
◍ Consensus model.
Answer: APRN practice model that aims to improve access to APRN care
by providing guidance for states to adopt uniformity in the regulation of
APRN roles, licensure, accreditation, certification, and educationSupports
nurses to work more easily across different states and enhance the ANCC
certification process by preserving the highest standards of nursing
excellence
◍ TRUE or FALSE? Arena primarily uses the Process-Interaction modeling
approach..
Answer: True
◍ Suppose the arrivals of clients to a bank can be modeled as a Poisson
process with a given hourly rate λλ . Then the number of clients arriving
between 10:00-11:00 am is independent of the number of clients arriving
between 1:00-2:00 pm..
Answer: True
, ◍ Professional leader.
Answer: Leading at the organizational level or delivery system level
◍ What is an example of role stress.
Answer: Going back to school while maintaining work and family
responsibilities, the expectations of increased workload, keeping up with
rapidly changing technology
◍ Suppose that X and Y are i.i.d. with a mean of −5, a variance of 4, and
Cov(X, Y) = 1. Find Corr(X, Y)..
Answer: 1/4
◍ Purpose of CHIP.
Answer: -provides federal matching funds to states for health insurance to
families w/ children that have incomes too high but cant afford private
coverage-to cover uninsured children in families w/ modest incomes but too
high to qualify for medicaid-gets same benefits as if in Medicaid
◍ Again consider the linear congruential generator . If calculate ..
Answer: 7
◍ if X has a mean of 2 and a variance of 6, find E[2-2x/3].
Answer: 2/3
◍ Suppose thatU Unif(0,1).What is the distribution
ofX=−1αln(1−U)?Suppose thatU Unif(0,1).What is the distribution
ofX=−1αln(1−U)?.
Answer: Exp(α)Exp(α)
◍ Consider the set-up from Problem 17, but now the line rule is LIFO
(last-infirst-out) — not FIFO! When does the third customer (i.e., the
customer who arrives at time 7) leave the system ?.
Answer: 21
◍ In Arena, what modules would I need to generate customer arrivals, perform
some action on them, and remove them from the system ?.
Answer: CREATE, PROCESS, DISPOSE
