A nurse is teaching a client about iron supplementation during pregnancy.
Which of the following client statements indicates an understanding of the teaching?

Choice A rationale

Fetal cardiac activity is typically detectable via transvaginal ultrasound as early as 5.5 to 6 weeks gestational age, when the embryo is approximately 2-4 mm in crown-rump length. However, hearing the heartbeat with a Doppler stethoscope usually occurs later, around 10 to 12 weeks, as the fetal heart is still very small and sound transmission is limited.

Choice B rationale

The standard schedule for prenatal visits involves monthly appointments from the first prenatal visit until 28 weeks of gestation. This frequency allows for consistent monitoring of maternal and fetal well-being, early detection of potential complications, and timely interventions. After 28 weeks, visits typically become more frequent.

Choice C rationale

While a complete blood count (CBC) is a crucial laboratory test performed during pregnancy, it is not typically done at every prenatal visit. Initial CBCs are obtained at the first prenatal visit to establish baseline values, and then repeated later in pregnancy, often around 28 weeks, to screen for anemia and other hematologic changes.

Choice D rationale

Screening for neural tube defects, often through maternal serum alpha-fetoprotein (MSAFP) testing, is typically performed between 15 and 20 weeks of gestation. This timing is crucial for accurate interpretation of results and allows for further diagnostic evaluation if abnormalities are detected, well before 32 weeks.

Choice A rationale

Encouraging the client to listen to music is an effective non-pharmacological pain management strategy in the latent phase of labor. Music provides a distraction, promotes relaxation, and can help to reduce the perception of pain by stimulating the release of endorphins, fostering a calmer environment and coping mechanism.

Choice B rationale

Instructing the client on biofeedback is a complex technique that requires training and practice for effective use. While it can be beneficial, the latent phase of labor may not be the ideal time to introduce and teach a new skill like biofeedback, as the client's focus may be limited by contractions and discomfort.

Choice C rationale

Administering fentanyl 100 mcg every hour via intermittent intravenous bolus is a pharmacological intervention typically used for more intense pain in active labor or for clients who desire or require stronger pain relief. The latent phase is characterized by milder, less frequent contractions, making non-pharmacological methods or lower-dose analgesics more appropriate.

Choice D rationale

Requesting a pudendal nerve block is usually reserved for the second stage of labor, specifically for episiotomy repair or forceps delivery, rather than for pain management during the latent phase. It provides regional anesthesia to the perineum and lower vagina, not generalized pain relief for uterine contractions in early labor.
