Study Notes

Therapeutic Communication

Acknowledge feelings of disgust in clients diagnosed with helminth infections, emphasizing that it is not a reflection of their character.

Common Helminth Infections

Pinworms are the most frequent cause of helminth infections in the United States.
Ascariasis, hookworm, and schistosomiasis are other notable infections requiring awareness and understanding.

Filariasis

Filariasis involves the infection of blood and tissues by worm embryos, potentially causing severe inflammatory reactions.
Can lead to symptoms such as elephantiasis through insect bites.

Treatment Considerations

Mebendazole, used for hookworm infections, necessitates teaching about hygiene practices to prevent reinfection.
Praziquantel is prescribed for schistosomiasis; clients should avoid fresh water to prevent reinfection.

Diagnosis and Care Planning

Obtaining stool samples is a priority for diagnosing helminth infections.
Registered dietitians may assist in care planning for clients with ascariasis due to nutritional needs.

Pediatric Considerations

Mebendazole is typically prescribed for children with pinworm infections; adherence to treatment is crucial.
Assessment of bowel movements, nutritional status, and fluid balance is essential for children undergoing treatment for whipworms.

Mechanism of Action

Mebendazole disrupts glucose metabolism in worms, preventing reproduction and leading to cell death.
Pyrantel is noted for requiring a single dose for its efficacy.

Family and Psychosocial Support

Helminth infections can affect clients’ self-esteem; supportive education and assurance of confidentiality are important.
Parents should be educated on the importance of meticulous hand-washing to prevent recurrence of pinworms.

Adverse Effects and Monitoring

Monitor liver enzymes (AST and ALT) in clients receiving mebendazole or albendazole.
Be alert to signs of renal failure in clients on albendazole, especially if they have pre-existing kidney conditions.

Specific Infections and Their Risks

Ingesting undercooked pork can lead to trichinosis.
High-fat meals should be avoided as they may interfere with the effectiveness of anthelmintic drugs.

Education and Follow-Up

Teaching on the importance of completing prescribed doses, including multiple doses of praziquantel or mebendazole.
Validate feelings of shame or disgust in clients while providing psychoeducation about their condition.

Drug Interactions and Contraindications

Highlight the contraindications of metronidazole, such as first trimester pregnancy and interactions with blood disorders.
Educate clients on the need for barrier contraception during anthelminthic treatment, especially if they are in childbearing age.

Preventative Measures

Emphasize the need for avoiding contact with potentially contaminated environments and adopting safe food handling practices to prevent helminthic infections.
Encourage regular monitoring and assessment of treatment efficacy and potential side effects during follow-up visits.
