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?
I need to cook meat thoroughly.
I need to drink unpasteurized milk only.
I need to avoid contact with materials that are possibly contaminated with cat feces.
I need to avoid touching mucous membranes of the mouth or eyes while handling raw meat.
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale
Edema, particularly peripheral edema, is a common clinical sign of preeclampsia. It results from fluid shifts due to increased vascular permeability and decreased plasma protein levels associated with the disease process.
Choice B rationale
Glycosuria, the presence of glucose in the urine, is not typically a symptom of preeclampsia. It is more commonly associated with gestational diabetes, a separate condition of pregnancy characterized by impaired glucose tolerance.
Choice C rationale
Proteinuria, the presence of significant amounts of protein in the urine (typically ≥300 mg in a 24-hour urine collection), is a hallmark sign of preeclampsia. It reflects glomerular endothelial damage and increased permeability.
Choice D rationale
Hypertension, defined as a blood pressure of ≥140/90 mmHg on two separate occasions at least 4 hours apart after 20 weeks of gestation, is a key diagnostic criterion for preeclampsia. It results from systemic vasoconstriction.
Correct Answer is A
Explanation
Choice A rationale
Deep tendon reflexes of +1 are hypoactive reflexes, indicating decreased neurological excitability. In preeclampsia, central nervous system irritability is a key feature, often leading to hyperreflexia, which would be documented as +2, +3, or +4. Therefore, +1 reflexes are inconsistent with preeclampsia.
Choice B rationale
3+ protein in the urine indicates significant proteinuria, which is a hallmark sign of preeclampsia. The kidneys are affected in preeclampsia, leading to increased excretion of protein in the urine.
Choice C rationale
A blood pressure of 148/98 mm Hg is elevated and falls within the diagnostic criteria for preeclampsia, which is hypertension (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg) that develops after 20 weeks of gestation along with proteinuria or other signs of end-organ damage.
Choice D rationale
Pitting sacral edema, or swelling in the sacral area that leaves a pit when pressed, is a common finding in preeclampsia due to fluid retention and increased capillary permeability.
