Answer to Question 1
Correct Answer: 3
Rationale 1: Helminthes are not transmitted by touching the hair.
Rationale 2: Avoiding sandwiches would not reduce the incidence of helminthiasis.
Rationale 3: Hand hygiene is most important.
Rationale 4: Although this is important, it is not the best answer, because helminthes are not transmitted in this manner.
Global Rationale: Helminthic infections generally occur when eggs from the parasites are ingested. This can occur due to poor hand hygiene. The remaining hygiene teaching is important but would not reduce helminthic transmission. Helminthic transmission is not related to ingestion of sandwiches.
Answer to Question 2
Correct Answer: 1
Rationale 1: Hemolytic anemia is the major adverse effect.
Rationale 2: This would indicate liver inflammation, which is not a primary adverse effect of primaquine.
Rationale 3: Photosensitivity is not an adverse effect of primaquine.
Rationale 4: This is a symptom of bile blockage, not an adverse effect of primaquine.
Global Rationale: Hemolytic anemia is the major adverse effect of primaquine, especially in patients with G6PD deficiency. Icterus, photosensitivity, and lack of bile in the stool are not known adverse effects.
