The nurse is teaching a prenatal class about signs of labor. Which statement indicates the need for further teaching?

Correct Answer: B

Rationale: In the context of teaching a prenatal class about signs of labor, option B, "The baby dropping is a sign of true labor," indicates a need for further teaching. This statement is inaccurate as the baby dropping, also known as lightening, occurs before labor begins and is not a definitive sign of imminent labor. Option A is correct as true labor contractions do indeed increase in intensity and regularity, which is a key characteristic distinguishing them from false labor. Option C is also accurate as false labor contractions, known as Braxton Hicks contractions, often subside with activity and rest, unlike true labor contractions. Option D is correct as true labor results in cervical changes such as effacement and dilation. To enhance understanding, it is crucial for prenatal educators to clarify the distinction between signs of true labor and false labor, emphasizing the importance of recognizing true labor onset to seek appropriate medical care. Providing practical examples, encouraging questions, and offering hands-on activities can aid in reinforcing this crucial information for expectant parents.

Correct Answer: B

Rationale: In the context of pharmacology in maternal newborn nursing, the primary goal of tocolytic therapy in a client experiencing preterm labor at 32 weeks' gestation is to delay delivery and improve fetal lung maturity (Option B). Tocolytic agents are used to inhibit uterine contractions temporarily, allowing time for corticosteroids to enhance fetal lung development and for the administration of magnesium sulfate for neuroprotection in the preterm neonate. Option A, to prevent fetal hypoxia, is not the primary goal of tocolytic therapy. While delaying delivery can indirectly contribute to reducing fetal hypoxia by allowing time for appropriate interventions, it is not the direct aim of tocolysis. Option C, to reduce maternal blood pressure, is not typically a primary goal of tocolytic therapy. Tocolytic agents primarily target uterine smooth muscle to delay labor and do not have a direct effect on maternal blood pressure. Option D, to increase uteroplacental blood flow, is not the primary goal of tocolytic therapy. While maintaining adequate uteroplacental perfusion is important in pregnancy, tocolytic therapy is specifically aimed at inhibiting uterine contractions to delay preterm labor and its associated risks. Understanding the rationale behind tocolytic therapy is crucial for nurses caring for pregnant individuals at risk for preterm labor. By delaying delivery, healthcare providers can optimize outcomes for both the mother and the preterm neonate, emphasizing the importance of fetal lung maturity and appropriate interventions before birth.

Correct Answer: B

Rationale: In maternal newborn nursing, routine ultrasound examinations play a crucial role in monitoring the health and development of the fetus. The primary focus of an ultrasound at 20 weeks' gestation is to evaluate fetal anatomy and growth. This is the correct answer (B) because at this stage, major structural abnormalities can be detected, such as neural tube defects, heart abnormalities, and abdominal wall defects. It also allows for assessing growth parameters like fetal size, amniotic fluid volume, and placental location, which are essential for determining the well-being of the fetus. Option A, confirming the baby's sex, is not the primary focus of a 20-week ultrasound. While sex determination can be done during this scan, it is not the main reason for the examination and should not be the primary focus. Option C, assessing maternal cervical length, is important but is typically done in the context of evaluating the risk of preterm labor, not during a routine ultrasound at 20 weeks' gestation. Option D, checking for signs of preterm labor, is also not the primary focus of a routine 20-week ultrasound. Signs of preterm labor would involve different assessments such as monitoring uterine activity, cervical changes, and assessing for symptoms like vaginal bleeding or pelvic pressure. Understanding the primary objectives of different prenatal assessments is crucial for providing comprehensive care to pregnant individuals and ensuring the well-being of both the mother and the fetus. By focusing on evaluating fetal anatomy and growth during a 20-week ultrasound, healthcare providers can detect potential issues early, provide appropriate interventions, and support optimal outcomes for both the mother and the baby.

Correct Answer: C

Rationale: In the context of educating a client with gestational diabetes about blood sugar monitoring, option C, "I will monitor my blood sugar four times a day as prescribed," is the correct statement that indicates understanding. This statement reflects the importance of regular monitoring as per the healthcare provider's instructions to manage gestational diabetes effectively. Option A, "I will check my blood sugar once a week," is incorrect because gestational diabetes requires more frequent monitoring due to the dynamic nature of blood sugar levels during pregnancy. Option B, "I should avoid all carbohydrates," is incorrect as complete avoidance of carbohydrates is not recommended. The focus should be on consuming complex carbohydrates in moderation and balancing them with proteins and healthy fats. Option D, "I can skip insulin on days I feel well," is incorrect as insulin therapy should be followed as prescribed by the healthcare provider, regardless of how the individual feels on a particular day. In an educational context, it is essential to emphasize the significance of consistent blood sugar monitoring to ensure timely adjustments in treatment plans, maintain optimal glucose levels for both maternal and fetal health, and reduce the risk of complications associated with gestational diabetes. Patients need to understand the rationale behind monitoring frequency and the potential consequences of inadequate monitoring or deviations from the prescribed management plan.

Correct Answer: A

Rationale: In fetal circulation, the correct answer is A) Ductus arteriosus. The ductus arteriosus is a fetal blood vessel that allows blood to bypass the fetal lungs by connecting the pulmonary artery to the aorta. This shunts blood away from the non-functional fetal lungs to ensure oxygenated blood is circulated throughout the body. Option B) Ductus venosus carries oxygenated blood from the placenta to the fetal heart, aiding in bypassing the liver. Option C) Foramen ovale is an opening between the atria of the fetal heart, allowing blood to bypass the pulmonary circulation. Option D) Umbilical vein carries oxygenated blood from the placenta to the fetus. Understanding fetal circulation is crucial in maternal newborn nursing as it impacts fetal oxygenation and overall well-being. Teaching this concept helps prenatal caregivers understand the unique circulatory adaptations in the fetus and recognize any deviations that may require intervention.
