A 5-month-old girl is transferred from an outside facility with concerns of bilateral ptosis, ophthalmoplegia, weak suck, mild diffuse hypotonia, and constipation that have developed and worsened over the past three days. A detailed history reveals that the infant was born at term via an uncomplicated home delivery. She has been previously healthy, growing, and normally developing. Her vaccine schedule has been delayed due to parental hesitancy. She has had no recent illness, sick contacts, or trauma. She has one healthy older brother who is homeschooled and she does not attend daycare. Her parents are gradually introducing her to new fruits and vegetables from their supply of home-canned goods, and she has thus far tolerated them well. Initial laboratory evaluation included unremarkable blood counts and liver panel. Serum chemistries were significant for a slightly elevated bicarbonate level. A capillary blood gas revealed a respiratory acidosis with partial metabolic compensation. A non-contrast CT of the brain was normal and subsequent cerebrospinal fluid analysis was normal. Which of the following is indicated for treatment?
-Botulism immune globulin
-Intravenous immunoglobulin
-Vancomycin and ceftriaxone
-Vitamin K administration
