ï‚· A healthcare provider prescribes cephalexin monohydrate (Keflex) for a
client with a postoperative infection. It is most important for the nurse to
assess for what additional drug allergy before administering this prescription?
A) Penicillins.
B)Aminoglycosides.
C) Erythromycins.
D) Sulfonamide
s. A)
Penicillins.
Cross-allergies exist between penicillins (A) and cephalosporins, such as cephalexin
monohydrate (Keflex), so checking for penicillin allergy is a wise precaution before
administering this drug.

ï‚· Which nursing intervention is most important when caring for a client
receiving the antimetabolite cytosine arabinoside (Arc-C) for
chemotherapy?
A) Hydrate the client with IV fluids before and after infusion.
B)Assess the client for numbness and tingling of extremities.
C) Inspect the client's oral mucosa for ulcerations.
D) Monitor the client's urine pH for increased
acidity. C) Inspect the client's oral mucosa for
ulcerations.
Cytosine arabinoside (Arc-C) affects the rapidly growing cells of the body, therefore
stomatitis and mucosal ulcerations are key signs of antimetabolite toxicity (C). (A, B,
and D) are not typical interventions associated with the administration of
antimetabolites.

ï‚· When assessing an adolescent who recently overdosed on acetaminophen
(Tylenol), it is most important for the nurse to assess for pain in which area of the
body?
A) Flank.
B)Abdomen.
C) Chest.
D) Head.
B) Abdomen.
Acetaminophen toxicity can result in liver damage; therefore, it is especially
important for the
nurse to assess for pain in the right upper quadrant of the abdomen (B), which
might indicate liver damage. (A, C, and D) are not areas where pain would be
anticipated.

ï‚· An adult client is given a prescription for a scopolamine patch (Transderm
Scop) to prevent motion sickness while on a cruise. Which information should the
nurse provide to the client?
A) Apply the patch at least 4 hours prior to departure.
B) Change the patch every other day while on the cruise.
C) Place the patch on a hairless area at the base of the skull.
D) Drink no more than 2 alcoholic drinks during the
cruise. A) Apply the patch at least 4 hours prior to
departure.
Scopolamine, an anticholinergic agent, is used to prevent motion sickness and has a
peak onset in 6 hours, so the client should be instructed to apply the patch at least 4
hours before departure (A) on the cruise ship. The duration of the transdermal patch
is 72 hours, so (B) is not needed.
Scolopamine blocks muscarinic receptors in the inner ear and to the vomiting center,
so the best application site of the patch is behind the ear, not at the base of the skull
(C). Anticholinergic medications are CNS depressants, so the client should be
instructed to avoid alcohol (D) while using the patch.
