Q

Pt with HL, HTN comes in with GRADUAL PAINLESS LOSS OF VISION and NO focal neuro deficits. What test is best to order first?

A

LATER PERSONALITY CHANGES

FRONTOTEMPORAL DEMENTIA: Early personality changes/ apathy/ disinhibition /compulsive behavior -> LATER memory changes

39

RANDOM ERROR

Increase sample size - Increases precision

HYPOCHLOREMIC METABOLIC ACIDOSIS

Due to INCREASED gut production and absorption of LACTIC ACID

49
Q

Which acid-base imbalance characterizes POSTICTAL STATE after seizure?

A

LACTIC ACIDOSIS - Due to INCREASED BMR -> Insufficient O2 present in tissues -> Anaerobic metabolism
