Which of the following medications has the least amount of evidence for its safety when used during pregnancy?

Correct Answer: C

Rationale: In early pregnancy, ensuring the safety of medications is crucial to prevent harm to the developing fetus. In this scenario, the correct answer is option C) Saxagliptin (category B3) because it has the least amount of evidence for its safety during pregnancy. Category B3 indicates limited human data or animal studies showing adverse effects on the fetus. Option A) Fluticasone propionate (category B3) is considered safer than Saxagliptin as it has more evidence supporting its use during pregnancy. Option B) Metformin (category C) is classified as category C, indicating conflicting evidence regarding its safety in pregnancy, but generally considered low risk. Option D) Budesonide (category A) is the safest choice as category A medications have the most evidence supporting their safety in pregnancy. Educationally, this question highlights the importance of understanding medication safety categories during pregnancy. Healthcare providers must weigh the risks and benefits of medication use, considering the available evidence to make informed decisions that minimize harm to both the mother and the developing fetus.

Correct Answer: C

Rationale: In early pregnancy, lactogenesis, the process of initiating milk production, can be influenced by various factors. The correct answer is C) Stress, as stress can significantly delay lactogenesis. Stress triggers the release of cortisol, a hormone that can interfere with the production of prolactin, the hormone responsible for milk production. High stress levels can inhibit prolactin production, leading to a delay in lactogenesis. Option A) Constipation is incorrect because it does not directly impact lactogenesis. Constipation may cause discomfort but does not have a direct physiological effect on milk production. Option B) Decreasing levels of progesterone is also incorrect. While progesterone plays a role in maintaining pregnancy, its decrease is a normal part of the transition to lactation and does not delay lactogenesis. Option D) Apnoea is unrelated to lactogenesis and does not have a direct impact on milk production. Educationally, understanding the factors that can influence lactogenesis is crucial for healthcare providers working with pregnant individuals. By recognizing the impact of stress on lactation, providers can offer support and interventions to help manage stress levels and promote successful breastfeeding outcomes. It is essential to educate both healthcare providers and pregnant individuals about the importance of stress management during pregnancy to support optimal lactation.

Correct Answer: B

Rationale: The correct answer is B) Folic acid prevents neural tube birth defects. Folic acid is a crucial nutrient during early pregnancy as it plays a key role in the development of the fetal neural tube, which eventually forms the baby's brain and spinal cord. By ensuring an adequate intake of folic acid, the risk of neural tube defects such as spina bifida and anencephaly can be significantly reduced. Option A) Folic acid does not prevent the development of contractions. Contractions are a natural part of the labor process and are not influenced by folic acid intake. Option C) Folic acid does not directly build fetal bones. While calcium is essential for bone development, folic acid primarily focuses on neural tube formation. Option D) Folic acid does not specifically target nausea and vomiting. Although some studies suggest a possible link between folic acid and reducing nausea, its primary role is in preventing neural tube defects rather than alleviating pregnancy symptoms. Educationally, it is important for healthcare providers to understand the specific benefits of folic acid in early pregnancy to effectively educate and counsel pregnant women on its importance. By emphasizing the role of folic acid in preventing neural tube defects, nurses can empower women to make informed decisions about their prenatal care to promote the health and well-being of both the mother and the baby.

Correct Answer: C

Rationale: Use of this manufactured hormone induces labor or augments weak, irregular uterine contractions during labor. It is not used in the labor phase to prevent bleeding. It is not administered to decrease fetal hyperactivity. The administration of oxytocin should allow for adequate periods of relaxation between contractions.

Correct Answer: D

Rationale: Rationale: The correct answer is D) Depressed deep tendon reflexes. When a patient's serum magnesium level is elevated, as in this case of magnesium sulfate administration, it can lead to hypermagnesemia. One of the hallmark signs of hypermagnesemia is the depression of deep tendon reflexes due to the inhibitory effect of magnesium on neuromuscular transmission. This presents as decreased or absent reflexes upon physical examination. Option A) Tachypnea is not typically associated with elevated magnesium levels. Instead, respiratory depression can occur in severe cases of hypermagnesemia. Option B) Muscle rigidity is more commonly seen in conditions like malignant hyperthermia or neuroleptic malignant syndrome, not specifically in cases of elevated magnesium levels. Option C) Tachycardia is not a characteristic sign of hypermagnesemia. In fact, magnesium can have a stabilizing effect on the heart and is used to treat certain cardiac arrhythmias. Educational Context: Understanding the signs and symptoms of hypermagnesemia is crucial for healthcare providers, especially in the context of administering medications like magnesium sulfate for preterm labor. Recognizing the manifestations of elevated magnesium levels can help prevent serious complications such as respiratory depression and cardiac arrhythmias. Regular monitoring of serum magnesium levels and clinical assessment for signs like depressed deep tendon reflexes are essential in managing patients receiving magnesium therapy.
