MULTIPLE CHOICE

 

1. When a patient is on aminoglycoside therapy, the nurse will monitor the patient for which indicators of potential toxicity?

a.	Fever
b.	White blood cell count of 8000 cells/mm3
c.	Tinnitus and dizziness
d.	Decreased blood urea nitrogen (BUN) levels

 

 

ANS:  C

Dizziness, tinnitus, hearing loss, or a sense of fullness in the ears could indicate ototoxicity, a potentially serious toxicity in a patient. Nephrotoxicity is indicated by rising blood urea nitrogen and creatinine levels. Fever may be indicative of the patient’s infection; a white blood cell count of 7000 cells/mm³ is within the normal range of 5000 to 10,000 cells/mm³.

2. The nurse is administering a vancomycin (Vancocin) infusion. Which measure is appropriate for the nurse to implement in order to reduce complications that may occur with this drug’s administration?

a.	Monitoring blood pressure for hypertension during the infusion
b.	Discontinuing the drug immediately if red man syndrome occurs
c.	Restricting fluids during vancomycin therapy
d.	Infusing the drug over at least 1 hour

 

 

ANS:  D

Infuse the medication over at least 1 hour to reduce the occurrence of red man syndrome. Adequate hydration (at least 2 L of fluid in 24 hours) during vancomycin therapy is important for the prevention of nephrotoxicity. Hypotension may occur during the infusion, especially if it is given too rapidly.

c.	Disturbed body image related to gynecomastia

a.	Metronidazole (Flagyl)
b.	Ciprofloxacin (Cipro)
c.	Vancomycin (Vancocin)
d.	Tobramycin (Nebcin)
