Correct Answer: D

Rationale: An ischemic stroke occurs when the blood supply to a part of the brain is obstructed, typically by a thrombus (a blood clot that forms in a blood vessel and remains attached to its place of origin) or an embolus (a blood clot that travels from a different part of the body and becomes lodged in a blood vessel in the brain). Another cause of ischemic stroke can be stenosis, which is the narrowing of a blood vessel, restricting blood flow to the brain. When the brain does not receive sufficient oxygen and nutrients due to the blockage, brain cells can be damaged or die, leading to a stroke. Ischemic strokes account for the majority of strokes and are essential to manage promptly to minimize brain damage and long-term disability.

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: C

Rationale: The nurse is monitoring vital signs and laboratory values for the patient recovering from a total knee replacement to ensure adequate circulation to the involved extremity. After a total knee replacement surgery, there is a risk of developing complications such as deep vein thrombosis (DVT) or impaired circulation to the surgical site. Monitoring vital signs and laboratory values allows the nurse to assess for any signs of compromised circulation, which could indicate the development of complications requiring immediate intervention. By closely monitoring these parameters, the nurse can ensure that the patient's recovery is progressing smoothly and without any major complications impacting the circulation to the involved extremity.
