On physical examination, his temperature is 38°C, respirations are 40/min and unlabored, the pulse is 120/min, and blood pressure is 75/50 mm Hg. Serum analysis reveals leukocytosis with a left shift. Blood chemistry and urinalysis are normal. Blood cultures are drawn. What is the most important next diagnostic step?
- Brain imaging
- Lumbar puncture
- Arterial blood gases
- Chest x-ray

- Listeria monocytogenes
- Haemophilus influenzae
- Neisseria meningitidis
- Staphylococcus aureus

it's a well prepared material and professional doctor thank you sir
First of all, love the option to choose the speed of the video clip. Secondly, it was smartly taught, no matter which type you are, from visual to auditory-learner, you are going to understand and learn it easily. I also loved Dr. Fisher's (the lecturer) teaching style, brief description for medical terms, mentioning important DDx, plus his tone and not having specific accent.
