Mike with epilepsy is having a seizure. During the active seizure phase, the nurse should:

Correct Answer: D

Rationale: The correct answer is D because placing the client on his side helps prevent aspiration and ensures an open airway. Removing dangerous objects prevents injury, and protecting the head prevents head injury. Placing the client on his back (A, C) can lead to aspiration, and holding down his arms (C) can cause injury.

Correct Answer: C

Rationale: The correct answer is C: Radiation. Vaginal cancer is commonly treated with radiation therapy because it allows for targeted treatment to the affected area. It is effective in killing cancer cells and reducing the size of tumors. Surgery (choice A) may be considered depending on the stage of cancer, but radiation is often the primary treatment. Chemotherapy (choice B) and immunotherapy (choice D) are not typically used as first-line treatments for vaginal cancer. Chemotherapy may be used in advanced stages or in combination with radiation, while immunotherapy is still being studied for its effectiveness in treating this type of cancer.

Correct Answer: A

Rationale: The correct answer is A: Liver. Cancer cells commonly metastasize to the liver due to its rich blood supply and filtering function. This allows cancer cells to easily travel through the bloodstream and settle in the liver. Other choices, such as B: Colon, and C: Reproductive tract, are possible metastatic sites but are not as common as the liver. Choice D: White blood cells (WBCs) is incorrect as WBCs are part of the immune system and not a typical site for cancer metastasis.

Correct Answer: C

Rationale: The correct answer is C: The cane should be used on the unaffected side. This is because when using a cane, it should be placed on the side opposite the affected or weaker side to provide additional support and balance. Placing the cane on the unaffected side helps to reduce pressure on the affected side and provides more stability during walking. A is incorrect because the choice between a cane and a walker depends on the individual's specific needs and abilities. B is incorrect as placing the cane on the affected side would not provide optimal support and balance. D is incorrect as using a cane can help reduce stress on joints in clients with osteoarthritis, making it a helpful assistive device.

Correct Answer: A

Rationale: The correct answer is A: Glucocorticoids and androgens. The adrenal cortex is divided into three layers, with each layer responsible for producing different hormones. The zona fasciculata produces glucocorticoids like cortisol, which regulate metabolism and immune response. The zona reticularis produces androgens, such as DHEA, which are precursors to sex hormones. Therefore, choice A is correct. Choices B, C, and D are incorrect because catecholamines like epinephrine and norepinephrine are produced in the adrenal medulla, not the adrenal cortex. Mineralocorticoids, like aldosterone, are produced in the zona glomerulosa of the adrenal cortex, not in the same layer as glucocorticoids and androgens.
