A prenatal nurse is providing instructions to a group of pregnant clients regarding measures to prevent toxoplasmosis.
Which statement, if made by one of the clients, indicates a need for further instructions?

Choice A rationale

Gonorrhea typically presents with a purulent, often thick, yellow discharge. While it can have a foul odor, the description of frothy and bubbly is less characteristic of gonorrhea. Diagnosis usually involves a cervical culture or nucleic acid amplification testing (NAAT).

Choice B rationale

Trichomoniasis, caused by the protozoan *Trichomonas vaginalis*, is characteristically associated with a large amount of yellow-green or gray, frothy, and bubbly vaginal discharge with a distinct, often foul or fishy odor. Microscopic examination of the discharge reveals the motile trichomonads for definitive diagnosis.

Choice C rationale

Chlamydia often presents with a thin or mucopurulent discharge, which may be yellowish, but it is not typically described as frothy or bubbly. Many women with chlamydia are asymptomatic. Diagnosis is usually made through NAAT of cervical or urine samples.

Choice D rationale

Syphilis in its primary stage presents with a painless chancre. Secondary syphilis can involve a generalized rash and flu-like symptoms. Vaginal discharge is not a primary characteristic of either the primary or secondary stages of syphilis. Diagnosis involves serological testing.

Choice A rationale

Thoroughly cooking meat to an internal temperature of 160°F (71°C) kills the Toxoplasma gondii parasite, thus preventing transmission through ingestion of contaminated meat. This is a crucial preventive measure recommended for pregnant women.

Choice B rationale

Drinking unpasteurized milk poses a risk of toxoplasmosis, as well as other foodborne illnesses like listeriosis and brucellosis. Pasteurization is a process that heats milk to a specific temperature for a set time, killing harmful bacteria and parasites, including Toxoplasma gondii. Therefore, this statement indicates a need for further instruction, as pregnant women should consume only pasteurized dairy products.

Choice C rationale

Cat feces can contain oocysts of Toxoplasma gondii, which can become infectious after a period of sporulation. Avoiding contact with materials possibly contaminated with cat feces, such as litter boxes and garden soil, is an important measure to prevent toxoplasmosis.

Choice D rationale

Handling raw meat can expose a person to Toxoplasma gondii cysts. Avoiding touching mucous membranes of the mouth or eyes after handling raw meat and washing hands thoroughly reduces the risk of self-inoculation with the parasite.
