Correct Answer: A

Rationale: A. V/Q scan: A ventilation-perfusion (V/Q) scan is a test used to diagnose pulmonary embolism by evaluating airflow and blood flow in the lungs. It is a common diagnostic test for suspected pulmonary embolism without DVT.

Correct Answer: B

Rationale: - Elevating the client's knees on the bed or with a pillow can help improve venous return and promote circulation, ultimately enhancing peripheral tissue perfusion in a client with DIC.

Correct Answer: D

Rationale: Early preeclampsia is a condition characterized by high blood pressure and signs of damage to another organ system, commonly the liver and kidneys. Severe epigastric pain is a common symptom of this organ involvement. It is caused by liver distention due to the breakdown of red blood cells and platelets, which can lead to a condition known as HELLP syndrome. This manifestation is a significant indicator of early preeclampsia and requires prompt evaluation and intervention to prevent complications for both the mother and the baby. While the other options may be present in preeclampsia, severe epigastric pain is a more specific and concerning symptom requiring immediate attention.

Correct Answer: A

Rationale: The Norwood procedure is a surgical technique used to treat hypoplastic left heart syndrome, a congenital heart defect where the left side of the heart is underdeveloped. In this procedure, the surgeon creates a new functional aorta and reconstructs the right ventricle to take over pumping blood to both the lungs and the body. This procedure is typically performed in 3 stages, with the first stage usually done in the first week of life. Providing client teaching about the Norwood procedure is important for the family to understand the surgery, postoperative care, and potential complications. It helps prepare them for what to expect and how to best support their infant through the surgical and recovery process.

Correct Answer: C

Rationale: Aphasia, which is the inability to understand or express speech, is typically associated with damage to the left hemisphere of the brain. In a client with suspected transient ischemic attack (TIA) presenting with aphasia, the nurse would plan care based on ischemia affecting the left hemisphere of the brain. The left hemisphere is responsible for language processing in most individuals, so damage in this area can result in communication deficits such as aphasia.
