8. How many vials of Revonto, a dantrolene formulation, should be
stocked on your malignant hyperthermia cart?
a. 32 c. 36
b. 34 d. 38
Answer: c
If your facility stocks Revonto or Dantrium on the MH cart, you need a
minimum of 36 vials along with at least 2400 ml of sterile water to recon-
stitute the drug. Cross reference all the medications on your MH cart
with the Malignant Hyperthermia Association of the United States'
(MHAUS) list of suggested supplies (osmag.net/Nnd5MQ). Also see
"Why Organized MH Carts Matter" on p. 20 for more information about
filling your carts' drawers with the supplies you'll need in the event of an
MH crisis.
9. It's acceptable for your facility to store various strengths of lidocaine.
a. true b. false
Answer: a
In general, you should always avoid stocking more than one strength of
the same drug. Why is this so important? Many medication errors —
especially those involving pediatric patients — are the result of a
provider using the wrong strength of a controlled substance. Lidocaine,
however, is one of those drugs where it's not only reasonable to stock
various strengths, it's also often unavoidable. Distinct drug auxiliary
labels, different color narcotic-use forms and separation in storage areas
are all proven error-reducing tactics to differentiate various versions of
lidocaine.
