Q- Which one of the following is the most appropriate next step in a suspected scaphoid fracture (with normal radiology)?
A- Admission and observation
B- Assurance and follow-up in 2 weeks
C- Emergent orthopedic consultation
D- Thumb spica splint
D- Thumb spica splint- A suspected scaphoid fracture can have normal initial X-rays, but the fracture may still be present. Because missed scaphoid fractures risk avascular necrosis, the correct step is to immobilize the wrist in a thumb spica splint and repeat imaging later.
Q- Which one of the following is a characteristic feature of Chlamydia?
A- Anaerobic bacteria
B- Facultative intracellular
C- Gram-negative diplococci
D- Obligate intracellular
D- Obligate intracellular- Chlamydia species cannot grow outside host cells because they rely on the host for ATP, making them obligate intracellular organisms. They are not anaerobic, not facultative intracellular, and not gram-negative diplococci (that describes Neisseria).
Q- Which of the following laboratory tests is diagnostic for adrenal insufficiency?
A- ACTH stimulation test
B- CT scan of the adrenal gland
C- Serum ACTH
D- Serum cortisol
A- ACTH stimulation test- The ACTH (cosyntropin) stimulation test is the diagnostic test for adrenal insufficiency because it measures the adrenal glands’ ability to produce cortisol in response to ACTH. A single cortisol or ACTH level cannot reliably confirm the diagnosis, and imaging is not diagnostic.
Thank you Dr Isaak
