Transcultural Concepts in Nursing Care Answers Test Banks

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: 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: 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: C

Rationale: The correct strategy to prevent hypertension is to decrease stress. Chronic stress can lead to high blood pressure, so managing stress levels through techniques such as mindfulness, exercise, adequate sleep, and relaxation techniques can help prevent hypertension. It is not advisable to increase salt intake, reduce physical activity, or consistently take hot baths as these can exacerbate hypertension or have no significant impact on preventing it.
