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: 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: When a client has an alteration in perfusion, particularly with inadequate oxygenation, positioning to increase blood return is essential in maintaining adequate tissue perfusion and oxygenation. By positioning the client in a way that maximizes venous return to the heart, the nurse can optimize cardiac output and improve oxygen delivery to the tissues. This can include elevating the legs slightly to facilitate blood return from the lower extremities, ensuring proper alignment of the body to prevent compression of major vessels, and promoting proper body mechanics to reduce the workload on the heart. Encouraging ambulation, instructing on deep breathing, and administering medications to increase heart rate may all have their place in certain scenarios, but for a client at risk for inadequate oxygenation due to perfusion issues, positioning to optimize blood return is the most crucial consideration.

Correct Answer: B

Rationale: Monitoring the pulse and not taking procainamide hydrochloride if the pulse is less than a specified rate is a crucial aspect of medication adherence for clients receiving this medication. Procainamide hydrochloride is an antiarrhythmic medication that can affect conduction and increase the risk of dangerous dysrhythmias. Therefore, monitoring the pulse rate helps in early identification of potential adverse effects, such as heart block, that may necessitate withholding the medication and seeking medical attention. By adhering to this instruction, the client can actively participate in their care to ensure safe and effective treatment with procainamide hydrochloride.

Correct Answer: D

Rationale: Virchow's triad describes the three pathological factors that are associated with the formation of a thrombus. These factors include endothelial injury, abnormal blood flow, and hypercoagulability. Endothelial injury disrupts the normal function of the endothelium, leading to the exposure of collagen and tissue factor, which triggers the coagulation cascade. Abnormal blood flow can result in stasis or turbulence, which promotes the accumulation of platelets and clotting factors. Hypercoagulability refers to an increase in the tendency of the blood to clot, which can be caused by various conditions such as genetic disorders, cancer, and certain medications. These three factors work together to increase the risk of thrombus formation.
