MULTIPLE CHOICE

 

1. A child has been diagnosed with enterobiasis, and the prescriber orders mebendazole [Vermox] to treat the infestation. When teaching this child’s parents about the treatment, the nurse will include which statement?

a.	“A single dose of mebendazole will eradicate the infestation.”
b.	“Everyone in the household should be treated with mebendazole.”
c.	“Serious complications of this type of infestation are common.”
d.	“Treatment should be limited to family members with symptoms.”

 

 

ANS:  B

Everyone in the family should be treated simultaneously, because pinworms are easily spread. To treat pinworms, an initial dose of mebendazole 100 mg is given, and the dose is repeated in 2 weeks. The infestation rarely causes serious complications. Treatment is not limited to symptomatic infestations.

2. A child is seen in the clinic after complaining of intense perianal itching. The provider diagnoses the child with pinworms and orders mebendazole [Vermox]. The nurse will expect to teach the child’s parents to:

a.	administer the drug with a high-fat meal to improve absorption.
b.	avoid driving or other hazardous activities until the drug’s effects wear off.
c.	give each family member one dose of the drug now and another dose in 2 weeks.
d.	report serious adverse effects that can occur with death of the causative parasite.

 

 

ANS:  C

Mebendazole is administered as a single dose once and then again in 2 weeks when given to treat pinworms. It should be given to all household members when one person is infested. Albendazole is given with a high-fat meal. Praziquantel can cause drowsiness. Ivermectin causes a Mazotti reaction, which occurs in patients treated for onchocerciasis with symptoms resulting from death of the parasite.

3. A patient tells the nurse that a close friend has ascariasis. The patient expresses worry about becoming infested. What will the nurse tell this patient?

a.	“Ascariasis usually resolves without treatment, so you should not worry.”
b.	“Avoid going barefoot and practice good hygiene and you won’t become infested.”
c.	“Treatment is always indicated if you are exposed, because ascariasis is contagious.”
d.	“You should be tested, because serious complications can occur without treatment.”

 

 

ANS:  D

Because this patient is worried about possible infestation, testing should be done so that treatment can be initiated if necessary. Because ascariasis can have serious complications, treatment is always indicated. Ascariasis infestations do not result from poor hygiene or from going barefoot. Ascariasis is not contagious, so treatment should begin only if the diagnosis is certain.

4. A young female patient is seen in a rural clinic after complaining of abdominal pain. The patient is wearing dirty clothing and is barefoot. The provider orders a complete blood count, which shows that the patient is anemic. The nurse may suspect that this patient has which of the following infestations?

a.	Ancylostomiasis (hookworm)
b.	Ascariasis (giant roundworm)
c.	Enterobiasis (pinworm)
d.	Trichuriasis (whipworm)

 

 

ANS:  A

Ancylostomiasis is most common when hygiene is poor and the patient habitually goes barefoot. Symptomatic anemia may occur in menstruating women or undernourished individuals. Ascariasis is usually asymptomatic. Enterobiasis is characterized by perianal itching. Trichuriasis is usually asymptomatic but may cause rectal prolapse if the worm burden is very large.
