Which analysis of maternal serum may predict chromosomal abnormalities in the fetus?

Choice A reason: This is incorrect because providing the patient with handouts is not enough to ensure effective communication. The handouts may not be in the patient's preferred language or may use unfamiliar words or concepts. The nurse should also use other methods, such as interpreters, translators, or visual aids, to convey information to the patient.

Choice B reason: This is incorrect because speaking quickly and efficiently may hinder the patient's comprehension and increase the risk of misunderstanding. The nurse should speak slowly and clearly, using simple and common words, and allow time for the patient to ask questions or clarify information.

Choice C reason: This is correct because assessing whether the patient understands the discussion is essential for effective communication and patient education. The nurse should use techniques such as teach-back, ask-me-3, or show-me to verify the patient's understanding and address any gaps or misconceptions.

Choice D reason: This is incorrect because using maternity jargon may confuse the patient and create barriers to communication. The nurse should avoid using medical terms, abbreviations, or slang that the patient may not be familiar with. The nurse should explain any necessary terms in plain language and use examples or analogies to illustrate them.

Choice A reason: An FHR greater than 110 beats/min is not a sufficient indicator of fetal well-being during labor. The normal range of FHR is between 110 and 160 beats/min, but it can vary depending on the gestational age, fetal activity, and maternal factors. A high or low FHR may indicate fetal distress or compromise.

Choice B reason: Maternal pain control is not a direct measure of fetal well-being during labor. However, maternal pain can affect the FHR indirectly by causing maternal stress, anxiety, or hyperventilation, which can alter the blood flow and oxygen delivery to the fetus. Therefore, adequate pain management is important for both maternal and fetal health.

Choice C reason: The response of the FHR to UCs is the most reliable and accurate way of assessing fetal well-being during labor. UCs can cause temporary reductions in the blood flow and oxygen supply to the fetus, which can affect the FHR. A normal response of the FHR to UCs is either no change or a slight increase (acceleration), which indicates a well-oxygenated and resilient fetus. An abnormal response of the FHR to UCs is a decrease (deceleration), which indicates a compromised or hypoxic fetus.

Choice D reason: Accelerations in the FHR are not a definitive measure of fetal well-being during labor. Accelerations are transient increases in the FHR above the baseline, usually caused by fetal movement, stimulation, or UCs. Accelerations are generally reassuring and indicate a responsive and well-oxygenated fetus, but they are not always present or consistent. The absence of accelerations does not necessarily mean fetal distress, as some fetuses may have periods of sleep or reduced activity.
