Nurse Kris is teaching a client with history of atherosclerosis. To decrease the risk of atherosclerosis, the nurse should encourage the client to:

Correct Answer: B

Rationale: The correct answer is B: Increase his activity level. Regular physical activity helps improve circulation, lower blood pressure, and reduce cholesterol levels, all of which can help decrease the risk of atherosclerosis. Exercise also helps maintain a healthy weight and reduces stress, which are additional risk factors for atherosclerosis. Explanation for other choices: A: Avoid focusing on his weight - Weight management is important in reducing the risk of atherosclerosis, so focusing on weight is beneficial. C: Follow a regular diet - Following a healthy diet is important, but alone may not be sufficient to reduce the risk of atherosclerosis without physical activity. D: Continue leading a high-stress lifestyle - High stress levels can contribute to the development of atherosclerosis, so it is important to reduce stress through relaxation techniques and exercise.

Correct Answer: A

Rationale: Correct Answer: A Rationale: A: The patient is under general anesthesia during bone marrow transplantation to ensure no discomfort or movement during the procedure, which involves inserting a needle into the bone. B: Aspirated bone marrow is mixed with anticoagulants like heparin to prevent clotting and ensure the cells remain viable. C: The iliac crest is a common site for bone marrow aspiration due to its accessibility and abundance of marrow-producing cells. D: The recipient receives preparatory chemotherapy like cyclophosphamide to suppress the immune system and reduce the risk of rejection during transplantation.

Correct Answer: B

Rationale: The correct answer is B: Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis. 1. TIS indicates carcinoma in situ, meaning abnormal cells are present but have not invaded nearby tissues. 2. N0 indicates no abnormal regional lymph nodes, suggesting no spread of cancer to the lymph nodes. 3. M0 indicates no evidence of distant metastasis, indicating the cancer has not spread to other parts of the body. Therefore, the classification TIS, N0, M0 signifies that the lesion is in the early stage, confined to its original location without lymph node involvement or distant spread. Incorrect choices: A: Incorrect - TIS indicates carcinoma in situ, not no evidence of primary tumor. C: Incorrect - The TNM classification is clear, not "Can't assess tumor or regional lymph nodes." D: Incorrect - TIS does not indicate ascending degrees of distant metastasis, and N0 indicates no abnormal lymph nodes, not "

Correct Answer: D

Rationale: Correct Answer: D (The client wears a watch and wedding band) Rationale: 1. MRI machines use strong magnetic fields, which can interact with metal objects like a watch and wedding band, causing them to move or heat up. 2. Movement of metal objects can lead to injury to the client or interfere with the imaging process. 3. It is essential for the client to remove all metal objects before entering the MRI room to ensure safety and accurate imaging. Summary: A: The client lying still is important for a successful MRI scan and does not pose a threat. B: Client asking questions does not pose a threat, as communication is normal during the procedure. C: Hearing thumping sounds is a common experience during an MRI scan and does not pose a direct threat to the client.

Correct Answer: A

Rationale: The correct answer is A (9 U regular insulin and 21 U NPH) because it closely matches the ratio of 70/30 insulin (70% NPH and 30% regular insulin). Regular insulin acts quickly to cover mealtime needs, while NPH provides intermediate-acting basal insulin. Option B has a higher proportion of regular insulin, which may lead to hypoglycemia. Option C has a lower proportion of regular insulin, which may not cover mealtime needs adequately. Option D has an equal ratio of regular and NPH insulin, not mimicking the 70/30 insulin ratio.
