Correct Answer: B

Rationale: Atropine, an anticholinergic medication, is used preoperatively to prevent bradycardia by increasing the automaticity of the sinoatrial node during surgical anesthesia. Choice A is incorrect because atropine does not affect gastric motility. Choice C is incorrect as atropine is not primarily used to reduce secretions. Choice D is also incorrect because preventing nausea and vomiting is not the primary purpose of administering atropine in this context.

Correct Answer: C

Rationale: The correct answer is C: reduced rates of childhood obesity. A reduction in childhood obesity rates is a direct indicator that the program is successful in achieving its goal. Increased participation in physical activities (choice A) and higher attendance at nutrition education sessions (choice B) are positive outcomes, but they do not directly measure the program's effectiveness in reducing obesity. Greater knowledge of healthy eating habits (choice D) is important but does not guarantee a decrease in obesity rates. Therefore, the most significant outcome to determine the success of a childhood obesity reduction program is a reduction in obesity rates.

Correct Answer: D

Rationale: The correct answer is 'D' - All of the above. The nurse should first determine the target aggregate that will be served by the program to understand the specific population in need. Subsequently, they should consider the pros and cons of different methods of data gathering to ensure the most appropriate data collection strategies are employed. Finally, selecting and training the data collection personnel is essential for the successful implementation of the program. These steps provide a logical progression from identifying the target group to analyzing the collected data. Choices A, B, and C are all crucial steps that must be taken in sequence to effectively develop and implement the smoking cessation educational program.

Correct Answer: A

Rationale: In the scenario of a primipara with a breech presentation and a prolapsed umbilical cord, the nurse should place the client in the supine position with the foot of the bed raised (Trendelenburg position). This position helps alleviate gravitational pressure by the fetus on the cord, preventing compression and reducing the risk of cord prolapse complications. Placing the client on the left or right side with legs elevated or in a prone position with the head elevated would not be appropriate in this situation, as they do not effectively relieve the pressure on the umbilical cord.

Correct Answer: A

Rationale: The correct answer is the importance of taking prenatal vitamins. Prenatal vitamins are crucial for the health of both the mother and the baby as they provide essential nutrients required for fetal development. While handling common discomforts of pregnancy (choice B) is important for maternal well-being, it does not directly impact the health of the baby. Preparing for labor and delivery (choice C) focuses more on the delivery process rather than the overall health of the mother and baby during pregnancy. Breastfeeding techniques (choice D) are relevant postpartum, not during the prenatal period, and do not directly impact the health of the baby during pregnancy.
