Si fiebre, ¿hemocultivos?

A 78-year-old man was refrerred from his residency where he lives to the emergency division due to general deterioration and frequent falls in the last week. His personal history is remarkable for arterial hypertension and diabetes. Two weeks before he needed a vesical catheterism that was traumatic and profilactic ciprofloxacin was prescriped. On phisical exploration he appears desoriented, blodd pressure is 9/40 mmHg, cardiac rythm 120 beats per minute, temperature 37,3°C and 24 respirations per minute. He appears to have pain on his upper left abdomen cuadrant. When the nurse gets a peripheral vein she asks, ?should I obtain hemocultures?
