Correct Answer: C

Rationale: A vaginal birth is preferred over a Cesarean section for women who have aortic stenosis. Aortic stenosis is a type of congenital heart disease that restricts blood flow from the heart to the rest of the body due to a narrowing of the aortic valve. In women with aortic stenosis, the increased blood volume and heart rate during labor and delivery can put extra strain on the heart. However, in most cases, vaginal delivery is preferred over a Cesarean section to avoid the risks associated with major abdominal surgery, such as bleeding, infection, and thrombophlebitis. A vaginal birth allows for a more gradual and controlled increase in cardiac output compared to the more sudden changes that can occur during a Cesarean section. Additionally, the stress of labor may mimic the stress test for some patients, providing valuable information about their heart function. However, each case is unique and must be evaluated by the healthcare team

Correct Answer: D

Rationale: Beta blockers are commonly prescribed for patients with hypertrophic cardiomyopathy due to their ability to help lower heart rate, reduce myocardial oxygen demand, and improve diastolic filling time. They can also help to prevent arrhythmias in these patients. Digoxin, vasodilators, and nitrates are not typically used as first-line treatment for hypertrophic cardiomyopathy.

Correct Answer: A

Rationale: Disseminated intravascular coagulation (DIC) is a complex, life-threatening condition characterized by widespread activation of coagulation within the blood vessels. In the early stages of DIC, there is excessive clot formation (formation of small clots) throughout the body due to the dysregulation of coagulation factors. As the disease progresses, the body's clotting factors become depleted, leading to a state of systemic anticoagulation. This anticoagulant state increases the risk of hemorrhage (bleeding) as the blood is no longer able to adequately clot. Therefore, hemorrhage is a pathological change that occurs late in the course of DIC.

Correct Answer: C

Rationale: Patients with peripheral vascular disease (PVD) often undergo percutaneous transluminal angioplasty (PTA) as a non-surgical intervention to improve blood flow in the affected arteries. PTA involves the use of a catheter with a balloon at its tip, which is inflated at the site of arterial narrowing to widen the vessel by compressing the plaque and stretching the arterial walls. This procedure helps restore blood flow and can alleviate symptoms such as claudication and ischemia in patients with PVD. Stent placement, endarterectomy, and atherectomy are other interventions that may be used in the management of PVD, but PTA is specifically known for its role in improving arterial blood flow in these patients.

Correct Answer: A

Rationale: A. Avoid crossing the legs: Crossing the legs can impede blood flow and increase the risk of developing blood clots, so it is important for the client recovering from DVT to avoid this position.
