A nurse is assisting with the care of a client who is at 37 weeks of gestation and has placenta previa. Which of the following risks is the primary rationale the nurse should avoid performing a pelvic examination?

Choice A rationale :

Scrambled eggs. Taking ferrous sulfate with scrambled eggs is not the optimal choice because eggs contain phytates, which can bind to iron and reduce its absorption. Therefore, it may hinder the effectiveness of the iron supplement, and the client may not receive the full benefit of the medication.

Choice B rationale

A high-fibre meal. While fiber is generally beneficial for digestion and overall health, it is not the best choice to take with ferrous sulfate. Fiber can also interfere with iron absorption in the same way as phytates, potentially reducing the medication's effectiveness.

Choice C rationale

Orange juice. The nurse should instruct the client to take the ferrous sulfate with orange juice. Orange juice is an excellent choice because it is rich in vitamin C. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based sources like ferrous sulfate). By taking the medication with orange juice, the client can maximize the absorption of iron and improve the treatment of iron-deficiency anaemia.

Choice D rationale

Milk. Consuming ferrous sulfate with milk is not advisable. Calcium, present in milk, can inhibit the absorption of iron. Therefore, taking the medication with milk might reduce the efficacy of the iron supplement and not provide the desired therapeutic effect.

Choice A rationale:
Fetal head compression is unlikely to cause variable decelerations in the fetal heart rate. During contractions and labor, the fetal head may experience pressure, but this usually leads to early decelerations, not variable decelerations. Early decelerations are considered benign and are caused by the head's pressure stimulating the vagus nerve, resulting in a temporary decrease in heart rate.
Choice B rationale:
Umbilical cord compression is a known cause of variable decelerations in the fetal heart rate. When the umbilical cord is compressed, it can temporarily disrupt blood flow and oxygen supply to the fetus, leading to decelerations. Variable decelerations often appear as abrupt, sharp drops in the fetal heart rate and are typically characterized by their unpredictable
nature.
Choice C rationale:
Maternal opioid administration is not a direct cause of variable decelerations in the fetal heart rate. While opioids can cross the placenta and may affect the fetus, they are more likely to cause other issues, such as respiratory depression in the newborn, rather than variable decelerations.
Choice D rationale:
Uteroplacental insufficiency is not the primary factor causing variable decelerations. Uteroplacental insufficiency refers to an inadequate blood flow and oxygen delivery to the placenta, which can lead to late decelerations in the fetal heart rate, not variable decelerations.
