Cerebral angiography is considered the gold standard for diagnosing and pinpointing the location, size, and origin of cerebral aneurysms. It involves the use of contrast material injected into the cerebral arteries and imaging to provide detailed visualization of the blood vessels in the brain, which is essential for accurate diagnosis and planning treatment strategies.

The patient's ABG results indicate respiratory acidosis (pH 7.33, PaCO2 48 mm Hg) with a slightly elevated temperature (103.2° F). In the context of fever and acidosis, hemoglobin's affinity for oxygen decreases, a phenomenon described by the Bohr effect. This means that hemoglobin will release oxygen more readily to the tissues. Factors like increased temperature and acidosis cause a rightward shift in the oxyhemoglobin dissociation curve, reducing the affinity of hemoglobin for oxygen.References: = CCRN Exam Handbook, page 44

Lorazepam (Ativan) is most appropriate to administer in a patient who has smoked crack cocaine and is agitated, particularly after a generalized seizure. Benzodiazepines like lorazepam help to manage agitation and seizure activity associated with cocaine toxicity by providing sedative and anticonvulsant effects.References: = CCRN Exam Handbook, page 53
