Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

. A nurse is assessing a patient’s urinary output no as an indicator of diabetes insipidus related to a traumatic brain injury. The nurse identifies that an hourly output of which volume over 2 hours may be a positive indicator?

A	50 to 100 mL/hr
B	100 to 150 mL/hr
C	150 to 200 mL/hr
D	More than 200 mL/hr

Explanation:

Detailed explanation-1: -Every brain injury is different, but generally, brain injury is classified as: Severe: GCS 8 or less. Moderate: GCS 9-12. Mild: GCS 13-15.

Detailed explanation-2: -Activities that can increase ICP should be avoided. These activities include suctioning, coughing, vomiting, and compression of jugular veins. Patient care should not be clustered, as this may also cause an increase in ICP. A ventriculostomy can be used to continuously monitor a patient’s intracranial pressure.

Detailed explanation-3: -It is normally 7-15 mm Hg in adults who are supine, with pressures over 20 mm Hg considered pathological and pressures over 15 mm Hg considered abnormal. Note that ICP is positional, with elevation of the head resulting in lower values. A standing adult generally has an ICP of-10 mm Hg but never less than-15 mm Hg.
