A nurse is caring for a client who was recently diagnosed with breast cancer. The oncologist uses the TNM staging system to classify this case as T2, N2, M0. The nurse understands that TNM stands for:

Correct Answer: B

Rationale: The TNM staging system is a classification system for determining the size and extent of cancerous tissue. The TNM system helps providers to identify the most accurate forms of treatment. The T stands for tumor, the N stands for node involvement, and the M stands for metastasis. Choice A, 'Tumor, Necrosis, Metastasis,' is incorrect because it does not include the node involvement component. Choice B, 'Tumor, Node Involvement, Mastectomy,' is incorrect as it erroneously includes the treatment approach 'Mastectomy' instead of 'Metastasis.' Choice D, 'Therapy, Necrosis, Metastasis,' is incorrect because it includes 'Therapy' instead of the correct component 'Node Involvement.'

Correct Answer: A

Rationale: Decorticate posturing is indicative of an injury to the corticospinal tract, resulting in abnormal posturing. It may occur spontaneously or in response to stimulation. This posture involves the legs being extended and rotated internally, while the elbows, wrists, and fingers are flexed inward. Choice A is correct because it accurately describes the expected positioning associated with decorticate posturing. Choices B, C, and D are incorrect. Choice B describes a different type of posturing known as opisthotonos. Choice C describes an exaggerated arching of the back, which is not characteristic of decorticate posturing. Choice D describes a different type of posturing with external rotation of the legs and head turning to the side, not consistent with decorticate posturing.

Correct Answer: D

Rationale: Increased intracranial pressure can lead to serious complications if not promptly addressed. Common signs of increased intracranial pressure include decreased level of consciousness, sluggish pupil dilation, abnormal respirations, and projectile vomiting. However, an increased heart rate is not a typical sign associated with increased intracranial pressure. It is important for healthcare providers to recognize these signs early to prevent severe consequences such as brain herniation.

Correct Answer: B

Rationale: In a client with a spinal cord injury, administering stool softeners as ordered is a crucial nursing intervention. Patients with spinal cord injuries are at higher risk of constipation due to decreased mobility. Stool softeners help prevent constipation and potential fecal impaction. Turning the client and using incentive spirometry each shift can be beneficial for respiratory function but is not the most vital intervention in this scenario. Turning the head slowly to avoid further damage to the spine is important but is not directly related to preventing constipation. Changing NPO status is not relevant to preventing constipation or managing a spinal cord injury.

Correct Answer: B

Rationale: Glioblastoma multiforme is the most common malignant brain tumor in the United States, accounting for a significant portion of cases. It is known for its aggressive nature and poor prognosis. Surgical resection, followed by radiation and chemotherapy, is the standard treatment approach for glioblastoma multiforme. Meningioma, acoustic neuroma, and pituitary adenoma are also types of brain tumors but are not as common as glioblastoma multiforme in the United States.
