Correct Answer: C

Rationale: During the first trimester of pregnancy, it is crucial to advise pregnant clients to avoid alcohol, caffeine, and smoking. These substances can worsen nausea and harm fetal development. By eliminating these substances, the client can help alleviate nausea and create a healthier environment for the developing fetus. Choices A, B, and D are not as critical in managing nausea during the first trimester. While relaxation techniques may help, avoiding harmful substances like alcohol, caffeine, and smoking takes precedence. Increasing fluid intake can be beneficial but not as crucial as avoiding harmful substances. Eliminating snacks between meals may not be necessary for all clients and is not directly related to managing nausea in the first trimester.

Correct Answer: A

Rationale: The correct answer is A: 'Prevent hemorrhagic disorders.' Phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease by promoting blood clotting. Newborns are born with low levels of vitamin K, which is essential for blood clotting, hence the administration to prevent hemorrhagic disorders. Choice B is incorrect because phytonadione is not given to help an immature liver but to supply vitamin K. Choice C is incorrect as phytonadione is not administered to improve dietary intake but to provide essential vitamin K. Choice D is incorrect as phytonadione does not stimulate the immune system but helps with blood clotting.

Correct Answer: B

Rationale: In a child with a sickle cell crisis, the priority intervention is to initiate normal saline IV at 50 ml/hr to manage dehydration and help alleviate pain. This intervention helps improve hydration status and supports the circulation of sickled red blood cells, reducing the risk of vaso-occlusive episodes and associated pain. Obtaining a culture of any sputum or wound drainage (Choice A) may be necessary but is not the initial priority. Administering a loading dose of penicillin IM (Choice C) is important but not the first intervention. Administering the initial dose of folic acid PO (Choice D) is beneficial but does not address the immediate need for hydration in a sickle cell crisis.

Correct Answer: C

Rationale: Monitoring for bleeding from IV sites is the priority intervention in this situation. The dark red vaginal bleeding, uterine tension, and other assessment findings suggest a potential placental abruption. Monitoring bleeding from IV sites can help detect coagulopathy, which may be associated with placental abruption. Options A, B, and D are not the most appropriate interventions in this scenario. Inserting an internal fetal monitor, assessing for cervical changes, and performing Leopold's maneuvers are not the priority actions when dark red vaginal bleeding and uterine tension are present, indicating a potential emergency situation.

Correct Answer: A

Rationale: Lying prone with a pillow on the abdomen is the most helpful intervention in relieving postpartum uterine contractions or 'afterpains.' This position provides counter-pressure and support to the uterus, helping to alleviate discomfort and promote uterine involution. Choice B, using a breast pump, is not effective in relieving afterpains as it focuses on milk expression. Massaging the abdomen (Choice C) may help with discomfort but does not provide the same level of support as lying prone with a pillow. Giving oxytocic medications (Choice D) is not typically the first-line intervention for afterpains unless there are specific medical indications.
