If the patient weighs 70 kg, at least 700 mg is need-
ed. Dantrium and Revonto, two dantrolene prod-
ucts, come packaged in 20 mg vials. Each vial
should be reconstituted for injection by adding 60
ml of sterile water and shaken until the solution is
clear. Ryanodex, a third dantrolene option, is pack-
aged in 250 mg vials. It must be
reconstituted with 5 ml of sterile
water and shaken into an orange-
colored opaque suspension. In
order to have enough dantrolene
on hand to administer the initial
dose, you must stock 30 vials of
Revonto and Dantrium, and three
vials of Ryanodex.
6. Which two medications are
used to treat glaucoma and anx-
iety, respectively?
a. acetohexamide
b. acetazolamide
c. hydralazine
d. hydroxyzine
Answer: b & d
Acetazolamide is the generic
form of Diamox. It's a sulfur-
containing product that is used
to relieve intraocular pressure
caused by glaucoma.
Acetohexamide is the generic
form of Dymelor, an older
antidiabetic drug. Hydroxyzine
is the generic version of Vistaril
or Atarax and can be used to
address anxiety. It can also be
used to treat nausea and itch-
ing. Hydralazine is an antihyper-
tensive, with a trade name of
Apresoline. These drugs have
very different uses but are easi-
ly confused because they have
similar sounding names. When
handling Look Alike/Sound
Alike (LASA) medications, be
sure to separate them in drug
storage areas. If their labels are handwritten, use
tall man lettering — writing part of a drug's name
in capital letters — to differentiate it from simi-
lar-looking drugs. When using pre-printed labels,
color-code drugs based on their classifications to
help avoid confusion during administration.
