Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: Helping the family recognize the problem is the most appropriate intervention to assist them in performing health tasks. By recognizing the problem, the family can better understand the need for action and be motivated to take steps to address it. This intervention enables the family to become more engaged in their healthcare decision-making process and enhances their ability to effectively manage their health tasks. It empowers them to seek appropriate health resources and make informed choices in promoting their health and well-being. Ultimately, by acknowledging the problem, the family is better equipped to initiate positive changes and improve their overall health outcomes.

Correct Answer: B

Rationale: The most critical action to prioritize for ensuring patient safety during a cardiopulmonary exercise stress test is to monitor the patient's electrocardiogram (ECG) rhythm continuously during the test (Option B). This monitoring allows the healthcare team to promptly detect any abnormal heart rhythms or signs of cardiac distress, enabling timely intervention if necessary. Continuous ECG monitoring is essential during exercise testing as it helps in assessing the heart's response to physical activity and identifying any potential cardiac abnormalities or complications that may arise during the test. By closely monitoring the ECG rhythm, the nurse can ensure the patient's safety and well-being throughout the procedure. Administering a beta-blocker medication before the test (Option A) may be indicated in some cases but is not as crucial as continuous ECG monitoring during the test. Encouraging the patient to consume a heavy meal before the test (Option C) is contraindicated as it can interfere with the accuracy of the results

Correct Answer: A

Rationale: T helper cells (Th cells) are primarily responsible for coordinating and regulating immune responses by producing cytokines that direct the activities of other immune cells. These cytokines help in activating cytotoxic T cells, B cells, macrophages, and other cells involved in the immune response. Th cells play a crucial role in mounting an effective immune response against infections and diseases by providing the necessary signals to activate and control various immune cells. Thus, T helper cells are considered the central coordinators of the immune system.

Correct Answer: C

Rationale: Used wet diapers and gloves should be disposed of in a black waste bin. Black waste bins are designated for general waste, which includes non-infectious materials that do not pose a risk of infection to others. Wet diapers and gloves fall under this category as they are considered non-infectious waste. Proper disposal in the black bin helps in maintaining cleanliness and hygiene in the healthcare setting.

Correct Answer: C

Rationale: The most effective intervention to prevent pressure ulcers in bedbound patients at risk, such as those with advanced dementia, is to use pressure-relieving support surfaces like specialized mattresses or cushions. These surfaces help distribute the pressure evenly, reducing the risk of pressure ulcer formation on bony prominences. Turning the patient every 2 hours (choice A) can also help relieve pressure, but it may not be sufficient to prevent pressure ulcers in high-risk individuals. Applying barrier creams or moisture barriers (choice B) can help protect the skin but may not address the underlying issue of pressure on vulnerable areas. Administering prophylactic antibiotics (choice D) is not recommended for preventing pressure ulcers as it does not address the root cause of the problem and can lead to antibiotic resistance. Therefore, the priority intervention should be to use pressure-relieving support surfaces to minimize the risk of pressure ulcers in
