A suspicious breast lump is noted on a mammogram. The client asks the nurse which diagnostic test confirms if the lump is cancerous or benign. Which response by the nurse is most correct?
An ultrasound.
A biopsy.
A clinical breast exam.
A magnetic resonance imaging (MRI).
The Correct Answer is B
. A biopsy is a procedure in which a sample of tissue is removed from the suspicious area and examined under a microscope to determine if the lump is cancerous or benign. An ultrasound uses sound waves to create an image of the breast tissue and is often used to evaluate the lump further. A clinical breast exam is a physical examination of the breast by a healthcare provider. Magnetic resonance imaging (MRI) may be used to obtain additional information about the lump, but it is not the primary diagnostic test.

Correct Answer is A
Explanation
Autonomic dysreflexia is a medical emergency characterized by a sudden onset of excessively high blood pressure, sweating, and headache. It is caused by an overactivity of the autonomic nervous system in response to a noxious stimulus below the level of a spinal cord injury.
Choice B is incorrect because the central nervous system includes the brain and spinal cord, while autonomic dysreflexia is caused by a spinal cord injury.
Choice C is incorrect because the sympathetic nervous system is part of the autonomic nervous system and is involved in the response to autonomic dysreflexia.
Choice D is incorrect because the peripheral nervous system includes the nerves that extend from the brain and spinal cord to the rest of the body.
Correct Answer is B
Explanation
Choice A is incorrect because stuporous is a state of reduced consciousness, and does not describe the posturing observed in the client.
Choice B is correct because decerebrate posturing is characterized by extension of the arms, wrists, and fingers, and extension and internal rotation of the legs, with plantar flexion of the feet.
Choice C is incorrect - Decorticate posturing is characterized by flexion of the arms, wrists, and fingers, extension, internal rotation, and adduction of the legs, with plantar flexion of the feet. This is caused by damage to the cerebral cortex and is indicative of a neurological problem.
