Which structures are part of the brain stem? Select all that
apply.
a) Pons
b) Midbrain
c) Cerebellum
d) Medulla oblongata - ANSWER-• Medulla oblongata
• Pons
• Midbrain
The term brain stem is often used to include the medulla, pons,
and midbrain. The cerebellum is not part of the brain stem.
Which drug, administered by the nurse to a client with a heart
rate of 40 and syncope, is a muscarinic blocking drug that will
increase the heart rate?
a) Atropine
b) Dopamine
,2|Page
c) Lidocaine
d) Epinephrine - ANSWER-• Atropine
The drug atropine is an antimuscarinic or muscarinic cholinergic
blocking drug that prevents the action of acetylcholine at
excitatory and inhibitory muscarinic receptor sites. Because it is
a muscarinic blocking drug, it exerts little effect at nicotinic
receptor sites.
While explaining the role of skeletal muscle relaxants, such as
succinylcholine, used during anesthesia, the faculty mentions
that these effects are caused by blocking:
a) N2, neuronal-type receptor, a type of nicotinic acetylcholine
receptor
b) Norepinephrine
c) Nicotinic acetylcholine receptors, muscle-type receptor (NM)
d) Muscarinic acetylcholine receptors - ANSWER-Nicotinic
acetylcholine receptors, muscle-type receptor (NM)
Some skeletal muscle relaxants, such as succinylcholine, can be
used to induce muscle relaxation and short-term paralysis in
anesthesia by blocking NM receptors at the neuromuscular

junction. The drug atropine is a competitive antagonist for the
muscarinic acetylcholine receptor that prevents the action of
acetylcholine at excitatory and inhibitory muscarinic receptor
sites. Norepinephrine is released at most sympathetic nerve
endings.
A client is having an upper endoscopy to determine the
presence of a gastric ulcer. After the procedure is performed,
the nurse instructs the client that he cannot have anything to
eat or drink until the return of the gag reflex. Which nerve is the
nurse testing for return of function?
a) Hypoglossal
b) Glossopharyngeal
c) Trigeminal
d) Abducens - ANSWER-Glossopharyngeal
The glossopharyngeal nerve innervates the stylophargeus
muscle, posterior external ear, taste buds of posterior half of
tongue, oral pharynx, parotid gland, pharyngeal muscles, and
the stylopharyngeus muscle. It affects the function of
proprioception, somesthesia, taste, gag reflex, salivary reflex,
and assists in swallowing.

The nurse is aware that the primary function of the sympathetic
nervous system is:
a) Maintenance of organ function during periods of minimal
activity
b) Conservation of energy and resource replenishment
c) Suppression of responses during threatened periods
d) Maintenance of vital functions and responding when there is
a critical threat to the integrity of the individual - ANSWER-
Maintenance of vital functions and responding when there is a
critical threat to the integrity of the individual
The sympathetic division maintains vital functions and responds
when there is a critical threat to the integrity of the individual—
the "fight-or-flight" response. The parasympathetic nervous
system is concerned with conservation of energy, resource
replenishment, and maintenance of organ function during
periods of minimal activity.
The bidirectional axonal transport system allows for the
transport of molecular materials (as opposed to electrical
impulses); anterograde transport has both slow and fast
components.
