A nurse is performing a focused assessment for a client's vision. What visual assessment is the nurse making when she extends her hand for the client to shake?
Depth perception
Peripheral vision
Color deficit
Double vision
The Correct Answer is B
Choice A Reason: Depth perception is the ability to judge the distance and position of objects in three-dimensional space. Depth perception is assessed by asking the client to touch the tip of a pen or pencil held by the nurse, or by using a stereopsis test.
Choice B Reason: Peripheral vision is the ability to see objects and movements outside the direct line of vision. Peripheral vision is assessed by asking the client to shake the hand of the nurse, who stands at an angle to the client's side, or by using a confrontation test.
Choice C Reason: Color deficit is the inability to distinguish certain colors or shades of colors. Color deficit is assessed by asking the client to identify numbers or shapes on a color plate test, such as the Ishihara test.
Choice D Reason: Double vision is the perception of two images of a single object. Double vision is assessed by asking the client to cover one eye and look at an object, then switch eyes and compare the images, or by using a cover-uncover test.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because preparing the client for an X-ray is not the first action that the nurse should take. An X-ray can help diagnose possible injuries or fractures, but it is not an urgent test. The nurse should first assess the client's level of consciousness and neurological status using a standardized tool such as the Glasgow Coma Scale.
Choice B reason: This is the correct answer because calculating a Glasgow Coma Score is the first action that the nurse should take. The Glasgow Coma Scale is a tool that measures the level of consciousness based on the eye-opening, verbal response, and motor responses. It can help determine the severity of brain injury and guide further interventions.
Choice C reason: This is incorrect because dimming the lights and turning off the TV are not the first actions that the nurse should take. These are environmental modifications that can help reduce sensory stimulation and prevent agitation or seizures, but they are not as important as assessing the level of consciousness and neurological status.
Choice D reason: This is incorrect because providing analgesics is not the first action that the nurse should take. Analgesics can help relieve pain and discomfort, but they can also alter the level of consciousness and mask neurological signs. The nurse should first assess the level of consciousness and neurological status, and then administer analgesics as prescribed.
Correct Answer is ["B","D","E"]
Explanation
The correct answers are b, d, and e.
Choice A: Slurred speech.
Slurred speech can be associated with increased ICP due to the pressure effects on the brain areas responsible for speech production. However, it is not typically considered a late sign of increased ICP. It may occur earlier in the progression as the brain's ability to coordinate muscle movements is affected.
Choice B: Bradycardia with a bounding pulse.
Bradycardia with a bounding pulse is a classic sign of Cushing's triad, which is a late and ominous sign of significantly increased ICP. It indicates that the body is attempting to increase arterial blood pressure to overcome the increased ICP and maintain cerebral perfusion. The normal range for adult heart rate is 60-100 beats per minute.
Choice C: Confusion.
Confusion can be an early sign of increased ICP as it can indicate changes in cerebral function. However, it is not specifically a late sign of increased ICP. Early signs of increased ICP can include headache, nausea, and confusion, as the brain is initially responding to the pressure changes.
Choice D: Hypertension with an increasing pulse pressure.
Hypertension with an increasing pulse pressure is another component of Cushing's triad. It reflects the body's compensatory mechanism to preserve cerebral blood flow in the face of rising ICP. An increasing pulse pressure (the difference between systolic and diastolic blood pressure) is a late sign of increased ICP. Normal pulse pressure is typically 30-40 mm Hg.
Choice E: Nonreactive dilated pupils.
Nonreactive dilated pupils are a late sign of increased ICP and indicate pressure on the cranial nerves that control pupil size and reaction to light. This is a grave sign and often indicates impending brain herniation.
Choice F: Hypotension with a decreasing pulse pressure.
Hypotension with a decreasing pulse pressure is not typically associated with increased ICP. In fact, hypertension with a widening pulse pressure would be more indicative of increased ICP as part of Cushing's triad.
