JR 101 FINAL PAPER UPDATED EXAM QUESTIONS AND
SOLUTIONS RATED A+
✔✔T/F the three ingredients in the Simplex P Bone Cement monomer are: methyl
methacrylate (monomer), toulidine, and barium sulfate. - ✔✔False -
Methylmethacrylate, N-dimethyl p - toulide and Hydroquinone??
✔✔The ingredient included in Simplex Bone Cement monomers (regardless of
brand/type) to prevent premature polymerization is: - ✔✔hydroquinone
✔✔T/F The ingredient in the monomer that initiates the chemical reaction (Producing
heat) that lets the bone cement mixture consolidate at room temperature is toulidine. -
✔✔True
✔✔T/F: the liquid component (monomer) of simplex P is sterilized by gamma radiation -
✔✔False
✔✔T/F PMMA (polymethylmethalcrylate) represents 15% of the powdered ingredients
used to prepare a dose of Simplex P Bone Cement. - ✔✔True
✔✔T/F The numbers 75-15-10 refer to the percentages of the three ingredients that
comprise the formula of the powder (polymer/co-polymer) for Simplex P Bone cement. -
✔✔True
✔✔T/F the methyl methacrylate styrene copolymer ingredient in Simplex P Bone
Cemenet powder contains 1.7% benzoyl peroxide. - ✔✔True
✔✔T/F The powder component of the Simplex P Bone Cement formula is sterilized by
gamma radaition? - ✔✔True
✔✔After combining the liquid and powder ingredients of Simplex bone cement
(regardless of brand or type) the resultant chemical reaction (with ref to heat generated
by the mass) creating a polymeric formation of a soft, pliable, dough-like mass is best
described as being: - ✔✔exothermic
✔✔T/F Simplex P Bone Cement uses zirconium dioxide in its powdered ingredients. It is
a contrast agent that allows the bone cement to be seen on x-ray. - ✔✔False - barium
sulfate i beleive
✔✔T/F Barium sulfate is an ingredient in the monomer of Simplex P Bone Cement that
provides a radiopacity in the final prepared dosage. - ✔✔False
, ✔✔T/F Simplex P Bone Cement is indicated for usage on certain types of pathological
fractures. - ✔✔True
✔✔T/F Although its fumes are not pleasant to inhale, the monomer utilized in mixing
Simplex P Bone Cement is expressly engineered to be non-flammable. - ✔✔False
✔✔T/F Regarding Simplex P Bone Cement; when preparing the ingredients for usage,
data from in vitro studies have shown that monomer loss is related primarily to the
duration of mixing and secondarily to the frequency of stirring the material. - ✔✔False
✔✔The chemical process of heat being applied to a bone cement monomer is a co-
polymer resulting in the formation of a dough-like mass that gradually hardens is called:
- ✔✔polymerization
✔✔T/F A bolus of Simplex P Bone Cement starts curing when it reaches a room
temperature of 451 degrees F (232.7 C). As a result we can derive the term Fahrenheit
451, which is the temperature it takes to properly cure bone cement in the human body.
- ✔✔False
✔✔T/F Unexpired doses of Simplex P having different lot and or control numbers, can
be used to prepare the material for surgical applications. - ✔✔True
✔✔T/F When preparing a dose of Simplex P Bone Cement for surgical use, the liquid
monomer component should be the initial ingredient placed in the mixing receptacle. -
✔✔False
✔✔T/F After an implant (using Simplex P Bone Cement) has been positioned and
impacted into the patient's prepared bone, the excess cement that extrudes from the
implant should not be removed until the material has completely hardened. - ✔✔False
✔✔The setting time of Simplex P Bone Cement can vary with the ambient temperature
in the OR , which by definition does not include the temperature of the utensils, mixing
and delivery equipment and the cement itself. - ✔✔False
✔✔The recomended storage for Simplex P Bone Cement is a well lit and dry area, with
a temperature between 43 F and 74 F. - ✔✔False
✔✔T/F Simplex P w Tobramycin has the same powdered formula as Simplex P except
for the addition of Tobramycin - ✔✔True
✔✔T/F Simplex P Tobramycin has a different liquid (monomer) formula as Simplex P
Bone Cement so that it will not compromise the medicinal effect of the antibiotic powder.
- ✔✔False
