A nurse is preparing to administer an osmotic diuretic IV to a client with increased intracranial pressure. Which of the following should the nurse identify as the purpose of the medication?

Reduce edema of the brain.

Increase cell size in the brain.

Expand extracellular ﬂuid volume.

Provide ﬂuid hydration.

Answer and Explanation

The Correct Answer is A

Choice A Reason: This is correct because an osmotic diuretic, such as mannitol, works by creating an osmotic gradient that draws ﬂuid from the brain tissue into the blood vessels, thereby reducing cerebral edema and intracranial pressure.

Choice B Reason: This is incorrect because an osmotic diuretic would decrease, not increase, the cell size in the brain by removing ﬂuid from the intracellular space.

Choice C Reason: This is incorrect because an osmotic diuretic would decrease, not expand, the extracellular ﬂuid volume by increasing the urine output and excreting excess ﬂuid from the body.

Choice D Reason: This is incorrect because an osmotic diuretic would not provide ﬂuid hydration, but rather cause ﬂuid loss and dehydration.

Correct Answer is B

Explanation

Choice A Reason: Equal amount of ﬂuid drainage in each collection chamber is not a sign of proper chest tube function. The amount of ﬂuid drainage depends on the type and extent of the client's injury or surgery, and may vary from one chamber to another.

Choice B Reason:Fluctuation of the fluid level in the water seal chamber(tidaling) indicates that the chest tube is functioning properly. This fluctuation corresponds with the client's respirations and shows that air or fluid is being effectively removed from the pleural space.

Choice C Reason:Continuous bubbling within the water seal chamber: Continuous bubbling in the water seal chamber indicates an air leak, which is not normal unless the client has a pneumothorax and air is being evacuated. Otherwise, it suggests a problem with the system.

Choice D Reason: Absence of ﬂuid in the drainage tubing is not a sign of proper chest tube function. It may indicate that the chest tube is obstructed, kinked, or clamped, or that the suction is not working properly. The nurse should assess and troubleshoot the chest tube system.

A. The client is in deep coma. B. The client needs total nursing care. C. The client is alert and oriented. D. The client is responding to verbal stimuli. E. The client is responding to verbal stimuli.

Correct Answer is B

Explanation

Choice A Reason: This is incorrect because the client is not in deep coma, as the Glasgow Coma Scale (GCS) score ranges from 3 to 15, with 3 being the lowest possible score and indicating deep coma or death.

Choice B Reason: This is correct because the client needs total nursing care, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only open his eyes to pain, make incomprehensible sounds, and have abnormal ﬂexion to pain.

Choice C Reason: This is incorrect because the client is not alert and oriented, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may not be able to follow commands, answer questions, or recognize people or places.

Choice D Reason: This is incorrect because the client is not responding to verbal stimuli, as the GCS score of 6 indicates a severe brain injury and a very low level of consciousness. The client may only respond to painful stimuli, such as pinching or squeezing.
