Adults and children older than 8 years of age with symptomatic giardiasis are usually treated with oral metronidazole. The administration of sulfasalazine is used to treat ulcerative colitis.

4. A woman is diagnosed with Trichomonas vaginalis. She is being treated with metronidazole (Flagyl) orally. What factor is most important in the care of this patient?

  1. A)  Instruct her on safe sex.
  2. B)  Instruct her to drink red wine.
  3. C)  Instruct her to take two tablets if a dose is missed.
  4. D)  Instruct her to have her partner treated.

Ans: D
The woman should be instructed that her partner should also be treated. Because trichomoniasis is transmitted by sexual intercourse, partners should be treated simultaneously to prevent reinfection. Although instruction on safe sexual practices is always important, it will not prevent reinfection, and the partner is infected asymptomatically. The patient should not drink while taking metronidazole. The woman should not double the dose if it is missed.

5. A home care nurse visits a patient who is bed bound and lives in a 12-story high rise apartment complex. Her daughter states that she has small red skin lesions over her body and she has been itching. What parasite is most likely responsible for this patient’s skin lesions?

Scabies are parasitic infestations of the skin. Scabies is caused by the itch mite (Sarcoptes scabiei), which burrows into the skin and lays eggs that hatch in 4 to 8 days. Pediculosis corporis is body lice. Pediculosis pubis is diagnosed by the presence of nits in the pubic and genital areas. Toxoplasma gondii is a parasite spread by ingesting undercooked meat or other food containing encysted forms of the organism.
