Correct Answer: B

Rationale: Pelvic pain is a common symptom of endometritis, which is an infection of the uterine lining. It is an important finding that warrants further evaluation. Localized area of breast tenderness may indicate mastitis, vaginal discharge with a foul odor could suggest a vaginal infection, and hematuria points towards a urinary tract issue, but they are not specific to endometritis.

Correct Answer: B

Rationale: Choice B, 'I will reduce my exercise schedule to 3 days a week,' indicates a need for further teaching. Regular exercise is beneficial in managing gestational diabetes and should not be reduced without proper guidance. Choices A, C, and D demonstrate understanding and appropriate actions in managing gestational diabetes.

Correct Answer: A

Rationale: The correct answer is hyperinsulinemia. In infants born to mothers with poorly controlled diabetes, the excess glucose crosses the placenta, leading to fetal hyperglycemia. This results in fetal hyperinsulinemia, which in turn can cause macrosomia (large birth weight), increasing the risk of respiratory distress syndrome due to the immature lungs' inability to handle the increased workload. Hyperinsulinemia, not increased deposits of fat, brachial plexus injury, or increased blood viscosity, is the most likely cause of respiratory distress in this scenario.

Correct Answer: A

Rationale: The nurse should prioritize seeing the client who experienced a cesarean birth 4 hours ago and reports pain first. Pain assessment and management are crucial post-cesarean birth to ensure the client's comfort and well-being. Immediate attention is needed to address the client's pain and provide appropriate interventions. The other clients may require attention but do not have an immediate postoperative concern like pain following a cesarean birth.

Correct Answer: B

Rationale: A missed miscarriage, also known as a silent or delayed miscarriage, occurs when the embryo or fetus has died, but no bleeding or contractions have occurred to expel it from the uterus. In this scenario, the client's experiencing slight occasional vaginal bleeding over the past two weeks indicates a missed miscarriage as the fetus has died, but the body has not recognized the loss or expelled the products of conception.
