A nurse is providing prenatal teaching to a client who practices a vegan diet and is trying to increase her intake of vitamin B12. Which of the following foods should the nurse recommend?

The correct answer is choice c. One acceleration of the FHR within a 20-min period.

Here's the rationale for each choice:

Choice A: Rationale: A non-stress test (NST) is supposed to assess fetal well-being by looking for accelerations in the fetal heart rate (FHR) in response to fetal movement. An FHR that peaks 20 beats above the baseline is a desirable finding in an NST, indicating good fetal reactivity.

Choice B: Rationale: While not typical during a standard NST, three uterine contractions within a 20-minute period might not necessarily require immediate intervention. However, the nurse should document it and notify the healthcare provider for further assessment, especially if the contractions are causing discomfort or if there are other concerning signs.

Choice C: Rationale: A single acceleration of the FHR within a 20-minute NST is considered non-reactive and may indicate fetal compromise. This finding requires further investigation by the healthcare provider, potentially including additional monitoring or interventions.

Choice D: Rationale: Uterine contractions lasting 20 to 30 seconds each are not a typical finding during an NST, but they may not necessarily be a cause for immediate concern unless they are causing the client pain or are accompanied by other concerning signs. The nurse should document the contractions and notify the healthcare provider.

Choice A rationale:

A blood glucose level of 110 mg/dL is within the normal range for a non-pregnant individual. During pregnancy, the target range for blood glucose levels may vary, but 110 mg/dL does not typically raise concerns for preeclampsia.

Choice C rationale:

A haemoglobin level of 13 g/dL is within the normal range for a pregnant woman. While haemoglobin levels are important to monitor during pregnancy, this value alone does not indicate a significant concern related to preeclampsia.

Choice D rationale:

Deep tendon reflexes (DTR) of 2+ are within the normal range. Higher DTR levels may be concerning, but a 2+ rating is normal and does not raise immediate alarm for preeclampsia.
