A nurse is caring for 4 clients. Which of the clients below is at the highest risk for increased intracranial pressure?

A client who is experiencing severe hypotension.

A client who is admitted with a traumatic brain injury.

A client who recently experienced a myocardial infarction.

A client post-op from eye surgery.

Answer and Explanation

The Correct Answer is B

Traumatic brain injury (TBI) is a serious disruption in normal brain function caused by an external force, such as a blow to the head, fall, or penetrating injury. It ranges in severity from mild concussions to severe brain damage and can lead to temporary or permanent cognitive, physical, and psychological impairments. TBI is a leading cause of disability and death worldwide, often requiring urgent assessment, neuroimaging, and interventions to reduce intracranial pressure and preserve neurologic function.

Rationale for Correct Answer:
B. TBI often leads to cerebral edema or bleeding, both of which increase ICP and can cause brain herniation if unmanaged.

Rationale for Incorrect Answers:

A. Severe hypotension typically lowers cerebral perfusion pressure but does not increase ICP directly.

C. Myocardial infarction can have neurological complications (e.g., hypoxic injury) but does not usually raise ICP.

D. Eye surgery may cause localized swelling or pressure but is unlikely to result in elevated ICP unless there are specific complications.

Key Takeaways:
• Traumatic brain injury is the leading cause of increased ICP.
• ICP elevation can lead to herniation and death if untreated.
• Systemic issues like hypotension or MI don't usually elevate ICP directly.

Correct Answer is C

Explanation

A computed tomography (CT) scan of the head is a noninvasive diagnostic tool that produces cross-sectional images of the brain to assess for stroke, bleeding, or masses. To ensure clear images, the client must lie still throughout the procedure to avoid motion artifacts, which can distort the results. While the scan is relatively quick and painless, patient cooperation is key to image accuracy.

Rationale for Correct Answer:
C. You will need to lie still throughout the procedure: Movement during the CT scan can blur the images, making them less useful for identifying subtle neurological changes. Lying still is essential for image clarity and diagnostic accuracy.

Rationale for Incorrect Answers:

A. No metal objects can enter the procedure room: This applies more strictly to MRI scans, where magnetic fields can attract metal. CT scanners use X-rays, not magnets, so metal is not as strictly contraindicated—although clients may be asked to remove certain objects like jewelry to improve image quality.

B. You need to fast for 8 hours prior to the test: Fasting is only required for CT scans involving IV contrast, and even then, the duration is usually 2–4 hours, not H. If contrast is not used, fasting is not needed at all.

D. There will be a lot of noise during the test: CT scanners produce some sound but are much quieter than MRI machines. Excessive noise is not a concern for this type of imaging.

Key Takeaways:
• Stillness during a CT scan is critical for accurate imaging.
• CT does not require metal restrictions or noise precautions like MRI.
• Fasting is only necessary if contrast dye is to be used, and even then, only for a few hours.

A. Position the client prone. B. Position the client supine with the head of bed flat. C. Position the client left side-lying. D. Administer acetaminophen as ordered

Correct Answer is B

Explanation

A post-lumbar puncture headache occurs due to leakage of cerebrospinal fluid (CSF) from the puncture site, which leads to reduced intracranial pressure. The most evidence-based nursing action to reduce the risk of this complication is to position the client supine with the head of the bed flat immediately after the procedure. This position supports CSF pressure equilibrium and promotes closure of the dural puncture.

Rationale for Correct Answer:
B. Position the client supine with the head of bed flat: Lying flat reduces gravitational CSF leakage and encourages clot formation at the puncture site. This position is typically maintained for 4 to 8 hours to lower the incidence of post-lumbar puncture headaches, especially in the first critical hours after the procedure.

Rationale for Incorrect Answers:

A. Position the client prone: Although used in some cases, the prone position is not the standard recommendation for post-lumbar puncture care. It may provide pressure over the site but does not facilitate CSF pressure balance as effectively as lying supine.

C. Position the client left side-lying: This position is commonly used during the lumbar puncture for needle insertion but is not effective post-procedure for headache prevention.

D. Administer acetaminophen as ordered: Acetaminophen can relieve a headache after it occurs, but it does not prevent a post-lumbar puncture headache. Prevention is priority in the immediate post-procedural period.

Key Takeaways:
• The supine, flat position is best for preventing post-lumbar puncture headache.
• Post-LP headaches are caused by CSF leakage, and position helps promote closure of the puncture site.
• Analgesics treat symptoms but do not prevent the complication.
