Correct Answer: A

Rationale: African Americans have a higher prevalence of peripheral vascular disease (PVD) compared to other ethnic groups. Additionally, advancing age is a significant risk factor for developing PVD. Therefore, the 83-year-old African American male has the highest risk among the given options due to his age and ethnicity.

Correct Answer: B

Rationale: The nurse educator plans to include teaching the nursing students how to search for and evaluate health information on the internet during the lecture. This is important because in today's digital age, nurses need to be able to effectively navigate the vast amount of healthcare information available online. Teaching students how to search for reliable sources, critically evaluate the information they find, and distinguish between credible and non-credible sources will help them in their nursing practice. This knowledge is essential for evidence-based practice and providing quality care to patients. Additionally, nurses should be aware of ethical considerations related to accessing and using online healthcare information.

Correct Answer: D

Rationale: The nurse should include the instruction that the client can expect to be ambulating, or walking around, on the evening of surgery. Early ambulation after VAD placement is important to prevent complications such as blood clots, pneumonia, and muscle weakness. Encouraging early mobility can also improve overall recovery and decrease the risk of postoperative complications. It is important for the client to understand that they will be encouraged to begin moving around as soon as possible after the surgery.

Correct Answer: A

Rationale: For a patient with a small-bowel obstruction, the highest priority action is to maintain nasogastric suction. This helps to decompress the bowel and relieve the obstruction by removing fluid and gas from the gastrointestinal tract. It can also help prevent complications such as bowel perforation and reduce the risk of aspiration if the patient vomits. Managing the obstruction is crucial to prevent further complications and promote the patient's recovery. Administering prescribed analgesics, keeping strict intake and output records, and placing the patient in a semi-Fowler's position are important interventions but may not address the immediate need to relieve the obstruction.

Correct Answer: B

Rationale: The correct statement indicating that teaching was effective is "It's a protein that pulls water into my blood vessels." Albumin is a type of protein found in the blood that helps to maintain blood volume and pressure by pulling water into the blood vessels from surrounding tissues. In the case of a client recovering from hypovolemic shock, infusion of albumin 5% can help to restore blood volume and improve circulation. The other statements do not accurately describe the function of albumin in the body.
