Question 1 of 5
A client with lung cancer develops Homer’s when the tumor invades the ribs and affects the sympathetic nerve ganglia. When assessing for signs and symptoms of this syndrome, the nurse should note:
Correct Answer: A
Rationale: The correct answer is A: Miosis, partial eyelid ptosis, and anhidrosis on the affected side of the face. This is indicative of Horner's syndrome, which occurs due to the disruption of sympathetic nerve supply. Miosis (constricted pupil), ptosis (drooping eyelid), and anhidrosis (lack of sweating) are classic signs of Horner's syndrome. These symptoms occur when the tumor invades the ribs and affects the sympathetic nerve ganglia. Summary of other choices: B: Chest pain, dyspnea, cough, weight loss, and fever are more commonly associated with lung cancer but not specific to Horner's syndrome. C: Arm and shoulder pain and atrophy of arm and hand muscles are not typical signs of Horner's syndrome. D: Hoarseness and dysphagia are more common symptoms of compression of the recurrent laryngeal nerve, not Horner's syndrome.
Question 2 of 5
Following the American Cancer Society guidelines, the nurse should recommend that the women:
Correct Answer: B
Rationale: The correct answer is B: Have a mammogram annually. Mammograms are recommended by the American Cancer Society for breast cancer screening in women as they are effective in detecting early signs of breast cancer. Mammograms have been shown to reduce mortality rates from breast cancer. Annual mammograms are crucial for early detection and treatment. A: Performing breast self-examination annually is not recommended as a standalone screening method as it has not been shown to significantly reduce mortality rates. C: Having a normal receptor assay annually is not a standard screening test for breast cancer recommended by the American Cancer Society. D: Having a physician conduct a clinical examination every 2 years is not as effective as annual mammograms for detecting early signs of breast cancer.
Question 3 of 5
The nurse is teaching a client who suspects that she has a lump in her breast. The nurse instructs the client that a diagnosis of breast cancer is confirmed by:
Correct Answer: B
Rationale: The correct answer is B: Fine needle aspiration. This is because fine needle aspiration involves extracting cells from the lump in the breast for examination under a microscope to determine if they are cancerous. This procedure provides a definitive diagnosis of breast cancer. Breast self-examination (A) is a screening tool for detecting lumps but does not confirm a diagnosis. Mammography (C) is used for screening and detecting abnormalities but requires further testing for confirmation. Chest x-ray (D) is not useful for diagnosing breast cancer.
Question 4 of 5
After a transsphenoidal adenohypophysectomy, a client is likely to undergo hormone replacement therapy. A transsphenoidal adenohypophysectomy is performed to treat which type of cancer?
Correct Answer: C
Rationale: Rationale: 1. Transsphenoidal adenohypophysectomy is the surgical removal of the pituitary gland's adenohypophysis. 2. The procedure is used to treat pituitary tumors, which can be benign or malignant, but commonly referred to as pituitary adenomas. 3. Pituitary adenomas may secrete hormones excessively, leading to various endocrine disorders. 4. Hormone replacement therapy is required post-surgery to manage hormonal deficiencies. 5. Therefore, the correct answer is C (Pituitary carcinoma). Summary: A, B, and D are incorrect as they do not involve the pituitary gland, which is the primary target of a transsphenoidal adenohypophysectomy.
Question 5 of 5
Then the drug is stopped. When should treatment resume?
Correct Answer: A
Rationale: The correct answer is A because the drug should be resumed when the WBC count falls to 5,000mm3 to ensure the client's safety and efficacy of treatment. This criterion indicates that the client's immune system has recovered sufficiently to tolerate the drug. Choices B, C, and D are incorrect because they do not directly correlate with the client's immune system recovery, which is crucial for drug tolerance. Choice B focuses on the rise in WBC count, not the fall to a specific level. Choice C is related to a cosmetic side effect, not clinical readiness. Choice D is unrelated to immune system recovery.
