3. A patient is being treated at a hospital in Africa for multidrug-resistant falciparum malaria. The patient is to be given artemether (Artenam) and artensunate. Which additional condition that the patient has would warrant another choice of medication?

ANS:   D

First-degree heart block would warrant another choice of medication, because artemether and artensunate can cause a transient first-degree heart block.

A high, transient fever is a typical manifestation in a patient with malaria, therefore it is not abnormal.

The drugs require a high concentration of iron in the blood, therefore this is a desirable condition.

A pulse of 103 would have no bearing on the choice of medication; a high pulse may b expected with a fever.

4. A group of students from Greece is planning a mission trip to a region where malaria is endemic. For which of the following conditions should the nurse screen the students before starting primaquine therapy?

There are no indications to screen for Celiac sprue, hypothyroidism, or SIDAH.
