A nurse is caring for a full-term newborn diagnosed with persistent/patent ductus arteriosus (PDA). The newborn's caregiver asks the nurse, "What causes a PDA?" How will the nurse answer this question?

The correct order is: b, a, d, c

1. b) Position the patient in a supine position: The first step is to ensure the patient is in a supine position, which is lying on their back. This position provides the best access and visibility for the nurse to assess the fundus effectively. Ensuring the patient is comfortable and relaxed in this position is crucial before beginning the assessment.
2. a) Place one hand on the lower segment of the uterus: The next step involves placing one hand on the lower segment of the uterus. This helps to stabilize the uterus and provides support while the nurse palpates the fundus. It also prevents any excessive movement that could cause discomfort or complications.
3. d) Press at the level of the umbilicus to palpate the fundus: The nurse then presses at the level of the umbilicus (belly button) to palpate the fundus. The fundus is the top portion of the uterus, and assessing its position and firmness provides important information about the postpartum recovery process.
4. c) Gently massage the fundus in a circular motion: Finally, the nurse gently massages the fundus in a circular motion. This action helps to ensure the uterus remains firm and can help in preventing postpartum haemorrhage. If the fundus is not firm, the massage can stimulate uterine contractions to firm it up.

Choice A reason: Haemophilia patients often require Factor VIII replacement therapy before procedures such as dental cleanings to prevent bleeding. The statement that the child does not need Factor VIII before a dental cleaning indicates a misunderstanding of the need for prophylactic treatment.

Choice B reason: Aspirin is contraindicated for children with haemophilia as it can inhibit platelet function and increase the risk of bleeding. The statement that it is okay to use aspirin reflects a lack of understanding of the appropriate pain management for haemophilia.

Choice C reason: While it is important for children with haemophilia to stay active, certain high-impact or contact sports may increase the risk of bleeding and should be avoided. The statement that there are no limitations on the type of activities indicates a lack of awareness about the need to choose safe activities.

Choice D reason: Swimming is a low-impact activity that is generally safe and beneficial for children with haemophilia. It promotes cardiovascular fitness and muscle strength without putting undue stress on the joints or increasing the risk of bleeding. This statement demonstrates an understanding of appropriate activity choices for a child with haemophilia.
