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) Penicillins.

B) Aminoglycosides.

C) Erythromycins.

D) Sulfonamides.

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.

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.

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.
