Correct Answer is A

Explanation

A. Damage to the right hemisphere, particularly the parietal and temporal lobes, can cause difficulty with recognition (prosopagnosia) and spatial awareness.
B. Right hemiparesis (weakness of the left side of the body) is common with left hemisphere damage, not right hemisphere damage.
C. Aphasia (language impairment) is typically associated with left hemisphere damage.
D. Difficulty reading (alexia) is more common with left hemisphere stroke, which controls language processing.

A. BP 126/54 mm Hg, pulse 58 beats/min, respirations 10 breaths/min B. BP 112/56 mm Hg, pulse 98 beats/min, respirations 28 breaths/min C. BP 129/65 mm Hg, pulse 60 beats/min, respirations 20 breaths/min D. BP 172/54 mm Hg, pulse 58 beats/min, respirations 10 breaths/min

Correct Answer is D

Explanation

A. BP 126/54 mm Hg, pulse 58 beats/min, respirations 10 breaths/min - While the low pulse and respirations should be assessed, this blood pressure isn't as concerning.
B. BP 112/56 mm Hg, pulse 98 beats/min, respirations 28 breaths/min - These vital signs are within a safer range compared to the critical changes in D.
C. BP 129/65 mm Hg, pulse 60 beats/min, respirations 20 breaths/min - These are stable vital signs.
D. The BP of 172/54 mm Hg, combined with bradycardia (pulse of 58 beats/min) and hypoventilation (respirations of 10 breaths/min), is indicative of Cushing's triad, a late sign of increased intracranial pressure, which is an emergency requiring immediate attention.
