MULTIPLE CHOICE

1. The nurse is caring for a patient with severe symptomatic intestinal amebiasis who has just completed a 10-day course of metronidazole [Flagyl]. Which medication would the nurse expect to be ordered for the patient?

ANS:  B

The metronidazole concentration in the stomach remains low; therefore, some amebas survive. Using iodoquinol as the subsequent drug achieves high concentrations, killing the remaining amebas. Pentamidine, atovaquone, and nitazoxanide are indicated for the treatment of diseases other than amebiasis.

4. The nurse is monitoring a patient who is receiving an inhalation treatment with pentamidine [NebuPent]. The patient begins to cough and states that he is having trouble breathing. What is the best action by the nurse?

ANS:  A

Cough and bronchospasm are the most common adverse reactions associated with inhaled pentamidine. These reactions can be controlled with an inhaled bronchodilator. Reducing the rate of the inhalation treatment or discontinuing the treatment is not an appropriate action. Doing nothing is not sufficient when the patient is having trouble breathing.
