HESI PHARMACOLOGY EXAM

HESI PHARMACOLOGY EXAM
1. 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) Penicillin.
B) Aminoglycosides.
C) Erythromycins.
D) Sulfonamides.
A) Penicillin.
Cross-allergies exist between penicillin (A) and cephalosporins, such as cephalexin
monohydrate (Keflex), so checking for penicillin allergy is a wise precaution before
administering this drug.
2. 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.
3. 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.
