A patient with giardiasis is being treated with metronidazole. What comment by the patient would indicate that the nurse needs to provide further teaching?
A) "I can continue to work delivering pizza because the disease is not contagious."
B) "I will not lose my hair during drug therapy."
C) "I know I will experience diarrhea during this time."
D) "I shouldn't experience irregular menstrual periods."
A
Feedback:
Although giardiasis is not contagious, the patient should be encouraged not to drive or operate heavy equipment until the effects of the drug can be assessed because metronidazole can lead to central nervous system adverse effects, including dizziness and lack of coordination. The drug may also cause diarrhea. Loss of hair and irregular menstrual periods are not associated with this drug, so these statements would be correct and would not indicate the need for further teaching.
