The nurse is caring for a client experiencing autonomic dysreflexia. Which of the following does the nurse recognize as the source of symptoms?

Autonomic nervous system.

Central nervous system.

Sympathetic nervous system.

Peripheral nervous system.

Answer and Explanation

The Correct Answer is A

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 A

Explanation

Level of consciousness is improving. The effectiveness of mannitol treatment for a client with increased intracranial pressure can be assessed through the improvement of the level of consciousness. Mannitol is an osmotic diuretic that reduces cerebral edema and intracranial pressure. It works by increasing the osmotic pressure in the bloodstream, which draws fluid out of the brain and into the bloodstream. The reduction of intracranial pressure helps improve cerebral perfusion and blood flow. Therefore, improving the client's level of consciousness is the most important assessment finding to determine the effectiveness of mannitol treatment.

B is not the correct answer because a rise in blood pressure is not an indicator of the effectiveness of mannitol treatment.

C is not the correct answer because increased urine output is a side effect of mannitol treatment and does not necessarily indicate effectiveness.

D is not the correct answer because hyperpyrexia is not a symptom that is treated with mannitol.

A. Bone radiographs. B. Glucose tolerance test in combination with a Growth hormone measurement. C. Growth hormone levels. D. A serum glucose level.

Correct Answer is B

Explanation

Glucose tolerance test in combination with a Growth hormone measurement. Acromegaly is a condition in which there is an excess of growth hormone (GH) production by the anterior pituitary gland, resulting in abnormal growth of bones and tissues in the body. The definitive diagnostic test for acromegaly involves a glucose tolerance test combined with a measurement of GH levels. During the test, the client will be given a dose of glucose, and the GH levels will be measured before and after the glucose is given. In acromegaly, the GH levels remain elevated even after glucose administration.

Choice A, bone radiographs, may show the enlarged bones associated with acromegaly, but it is not the definitive diagnostic test for the condition.

Choice C, growth hormone levels, is not specific enough for diagnosing acromegaly, as elevated GH levels can occur in other conditions as well.

Choice D, a serum glucose level, is not specific for acromegaly, as the glucose level may be normal in clients with the condition.
