A previously fit and well 75-year-old lady is brought into hospital with confusion

A previously fit and well 75-year-old lady is brought into hospital with confusion. She complains of headache and muscle aching. She is lethargic, pyrexical and looks unwell. Fairly rapidly, she deteriorates to a point where she is minimally conscious, only groans when you ask her questions and is bedbound. She groans when you flex her neck. Blood cultures are performed as is a lumbar puncture. The blood culture reveals gram-positive rods. 

For the patient above, please select the SINGLE most appropriate antibiotic. Select ONE option from the list above.
