NURS661 MARYVILLE UNIVERSITY EXAM 1
PRACTICE SCRIPT 2026 QUESTIONS WITH
ANSWERS GRADED A+
⫸ Cortisol Answer: This potent stress hormone mobilizes energy stores,
stimulates the release of glucose, potentiates the release of adrenaline,
increases cardiovascular tone, and inhibits growth, immune, and
inflammatory responses.
⫸ Dopamine Answer: This substance is produced in the substantia nigra
and other areas in the brainstem; it is a key neurotransmitter for motor
action, integration of emotions and thoughts, and decision-making.
⫸ Endocrine messenger molecules Answer: All are hormones composed
of amino acids (in peptides, proteins, or glycoproteins) and are produced
by one tissue and conveyed through the bloodstream to effect a change
in growth or metabolism on another tissue.
⫸ Endorphin Answer: This endogenous opioid is found in a number of
brain areas. It produces analgesia, reduces anxiety, and promotes
calmness.
⫸ Gamma-aminobutyric acid (GABA) Answer: This inhibitory
neurotransmitter is found in most neurons in the central nervous system.
, ⫸ Glutamate Answer: It is found in all cells, and its major receptor, N-
methyl-d-aspartate (NMDA), helps to regulate brain development.
⫸ Immune messenger molecules Answer: These substances are
produced by the immune system and by nerve cells.
⫸ Norepinephrine (NE) Answer: Produced mainly in the locus
coeruleus, NE is a key neurotransmitter in the flight, fight, or freeze
stress response and affects mood, attention, and arousal.
⫸ Oxytocin Answer: This hormone is released from the pituitary to
contract the uterus in childbirth and during orgasm.
⫸ Serotonin (5HT) Answer: Produced in the raphe nucleus, 5HT plays a
role in arousal and the sleep-wake cycle and in modulation of mood.
⫸ Vasopressin Answer: The antidiuretic properties and high
concentrations can lead to arterial constriction and high blood pressure.
⫸ Adaptive Information Processing (AIP) Model (EMDR) Answer:
Trauma stores memories in a maladaptive way; EMDR facilitates
reprocessing to integrate memories adaptively.
⫸ Diathesis-Stress Model Answer: Mental illness arises from genetic
predisposition (diathesis) combined with environmental stressors.
