since
confusion
is
an
adverse
effect
of
antihistamines.
A

female
with
a
history
of
overactive
cough
would
be
a
candidate
for
an
antitussive.
The
58-year-old
male
with
COPD
and
the
35-year-old
female
with
postural

should
not
be

-
ANSWER-Always
rinse
the
mouth
and
gargle
after
using
the
nebulizer.
Patients
must
rinse
the
mouth
and
gargle
after
using
the
nebulizer
to
minimize
dry
mouth
or
throat,
throat
irritation,
and
hoarseness.
The
bronchodilator
should
be
given
first,
then
the
cromolyn.
The
drug
should
not
be
taken
if
the
patient
feels
that
he
is
having
an
asthma
attack.
Priming
the
inhalation
canister
by
pressing
three
times
is
an
intervention
that
applies
to
nedocromil.
The
nurse
is
caring
for
a
newly
admitted
patient
who
has
an
order
for
a

history
of
an
irregular
heartbeat,
and
her
home

include

action
should
the

take
first?
Notify
the
healthcare
provider
of
the
information.
Document
the
drugs
and
conditions.
Monitor
the
patient's
vital
signs
closely.
Instruct
the
patient
to
notify
his
healthcare
provider.
-
ANSWER-Notify
the
healthcare
provider
of
the
information.
Use
of
digitalis
and
antidepressants
are
contraindications
to
use
of
a
bronchodilator.
Although
documentation
of
information
and
vital
sign
assessments
are
important,
the
healthcare
provider
should
be
notified
first
so
that
drugs
may
be
adjusted.
The
nurse
should
speak
with
the
healthcare
provider,
not
the
patient.

classification
can
cause
the
rebound
effect?
Antihistamines
Antitussives
Bronchodilators

-

used
to
stop
or
decrease
coughing.

are
used
to
dilate
the
bronchi.
