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 amoebas survive. Using iodoquinol as the subsequent drug achieves high concentrations, killing the remaining amoebas.

Pentamidine, atovaquone, and nitazoxanide are indicated for treatment of diseases other than amebiasis.

The patient has experienced several episodes of Pneumocystis jiroveci pneumonia and now requires prophylaxis to help prevent recurrence. The nurse would expect which medication to be the preferred treatment option?

ANS:   A

The nurse should expect that the patient will be treated with pentamidine isethionate aerosol, one 300 mg treatment every 4 weeks, because this is the regimen for prophylaxis of P. jiroveci pneumonia.

Pentam 300 is injectable; it is not given PO.

IV injection of pentamidine is given daily for 2 to 3 weeks.
