The nurse is caring for a client with severe preeclampsia. What finding would indicate magnesium sulfate toxicity?

Correct Answer: B

Rationale: In the context of caring for a client with severe preeclampsia, magnesium sulfate is often used to prevent seizures. Therefore, monitoring for signs of magnesium sulfate toxicity is crucial. Option B, a respiratory rate of 10 breaths per minute, indicates magnesium sulfate toxicity as it is a central nervous system depressant and can lead to respiratory depression at toxic levels. This finding is a critical indicator of impending magnesium sulfate toxicity and requires immediate intervention. Option A, increased deep tendon reflexes, is actually a sign of magnesium deficiency rather than toxicity. Magnesium sulfate usually dampens reflexes, so an increase would not be indicative of toxicity. Option C, urine output of 50 mL/hour, is generally considered a normal urine output and is not specific to magnesium sulfate toxicity. Option D, a blood pressure of 160/110 mmHg, is a common finding in preeclampsia but is not a specific indicator of magnesium sulfate toxicity. Educationally, understanding the signs of magnesium sulfate toxicity is essential for nurses caring for pregnant clients with preeclampsia. It highlights the importance of close monitoring and prompt recognition of adverse effects to ensure the safety of both the mother and the baby.

Correct Answer: B

Rationale: In the context of pharmacology and maternal newborn care, it is crucial for nurses to educate clients about signs of preterm labor to ensure timely intervention and optimal outcomes. The correct answer, option B, low back pain and cramping, should be reported immediately because it can indicate the onset of preterm labor, which poses risks to both the mother and the newborn. These symptoms may signal cervical changes and uterine contractions that could lead to preterm birth. Option A, frequent urination, is a common symptom during pregnancy due to hormonal changes and the growing uterus pressing on the bladder. While it can be uncomfortable, it is not typically a sign of preterm labor. Option C, increased appetite, is also a common occurrence in pregnancy and does not directly correlate with preterm labor. It is important for pregnant individuals to maintain a balanced diet to support their nutritional needs during pregnancy. Option D, Braxton Hicks contractions, are often referred to as "practice contractions" and are usually irregular, mild, and do not cause cervical changes. While they can be uncomfortable, they are a normal part of pregnancy and not necessarily indicative of preterm labor. Educating clients about these distinctions empowers them to recognize concerning symptoms, seek timely medical attention, and potentially prevent preterm birth complications through early intervention and management. This knowledge is essential for promoting the health and well-being of both the mother and the newborn.

Correct Answer: B

Rationale: In the context of pharmacology and maternal-newborn care, understanding the rationale behind performing Leopold's maneuvers during labor is crucial for safe and effective nursing practice. Leopold's maneuvers are a series of four systematic steps that help the healthcare provider determine the position and presentation of the fetus in the maternal abdomen. The primary purpose of this assessment is to ascertain the fetal position and presentation within the uterus. This information is essential for assessing fetal well-being, planning for labor and delivery, and identifying any potential complications that may arise during the birthing process. Option A, evaluating fetal heart rate, is incorrect because Leopold's maneuvers do not directly assess the fetal heart rate. Monitoring fetal heart rate is typically done using electronic fetal monitoring or handheld Doppler devices. Option C, checking for uterine contractions, is incorrect as Leopold's maneuvers are focused on fetal position and presentation rather than assessing uterine contractions. Uterine contractions are usually monitored separately using tocodynamometry or palpation techniques. Option D, assessing amniotic fluid volume, is also incorrect as Leopold's maneuvers do not provide information about amniotic fluid volume. This assessment is usually done through ultrasound or physical examination techniques specific to evaluating amniotic fluid levels. By understanding the purpose and significance of Leopold's maneuvers in determining fetal position and presentation, pharmacology students and healthcare providers can contribute to safe and competent care for mothers and newborns during the labor and delivery process. This knowledge is essential for promoting positive maternal and neonatal outcomes and ensuring the best possible care for both patients.

Correct Answer: B

Rationale: The correct answer is B) Increase fiber intake and fluids. During pregnancy, hormonal changes can lead to slowed bowel movements and constipation. Increasing fiber intake and fluids can help soften the stool and promote bowel regularity. Fiber-rich foods like fruits, vegetables, whole grains, and legumes are recommended. Adequate hydration is also crucial to prevent constipation. This advice is safe, effective, and promotes overall maternal well-being. Option A) Take a laxative daily is incorrect because regular use of laxatives during pregnancy is not recommended without healthcare provider supervision due to potential risks to the fetus and the mother. Option C) Avoid physical activity is incorrect as physical activity, within safe limits, can actually help alleviate constipation by promoting bowel motility and overall health during pregnancy. Option D) Limit vegetable consumption is incorrect because vegetables are a good source of fiber, vitamins, and minerals essential for the health of both the mother and the developing fetus. Restricting vegetable consumption could lead to nutritional deficiencies. In an educational context, it's important for nurses to provide evidence-based advice to pregnant clients to promote their well-being and address common concerns like constipation with safe and effective strategies that align with best practices in maternal care.

Correct Answer: B

Rationale: The correct answer is B) It detects neural tube defects. The maternal serum alpha-fetoprotein (MSAFP) test is a screening tool used in prenatal care to detect neural tube defects such as spina bifida and anencephaly. During pregnancy, the fetus produces alpha-fetoprotein, which crosses the placenta and enters the mother's bloodstream. Abnormal levels of this protein can indicate a neural tube defect in the fetus. Option A) It screens for chromosomal abnormalities is incorrect because MSAFP does not specifically screen for chromosomal abnormalities; other tests like amniocentesis or chorionic villus sampling are used for that purpose. Option C) It confirms the gestational age of the baby is incorrect because MSAFP is not used to confirm gestational age. Ultrasound is the primary method for determining gestational age during pregnancy. Option D) It identifies the baby's sex is incorrect because MSAFP does not determine the baby's sex. Other tests like amniocentesis or ultrasound can reveal the baby's sex. Understanding the purpose of the MSAFP test is crucial in prenatal care to provide appropriate information and support to pregnant individuals. By knowing the correct purpose of this test, healthcare providers can offer appropriate counseling and follow-up care based on the results, contributing to positive maternal and newborn outcomes.
