Rank from narrow to broad spectrum
a. Meropenem
b. Amoxicillin
c. Cefalexin
d. Ceftriaxone
e. Pip taz
- Amoxicillin – Narrow spectrum (primarily effective against Gram-positive bacteria, some Gram-negative coverage)
- Cefalexin – First-generation cephalosporin (slightly broader than amoxicillin, better Gram-positive coverage with some Gram-negative activity)
- Ceftriaxone – Third-generation cephalosporin (broader spectrum, good Gram-negative coverage, moderate Gram-positive coverage)
- Meropenem – Carbapenem (very broad spectrum, covers Gram-positive, Gram-negative, and anaerobes, including ESBL-producing bacteria)
- Piperacillin/Tazobactam – Extended-spectrum penicillin with beta-lactamase inhibitor (broadest spectrum among these, excellent Gram-positive, Gram-negative, and anaerobic coverage, including Pseudomonas)
Rank from highest to lowest specificity for rheumatoid arthritis

Rank platelets from high to low

b. rheumatoid arthritis
c. Normal pregnancy
d. beta thalassaemia trait
e. Autoimmune thrombocytopenic purpura
- essential thrombocythemia
- rheumatoid arthritis
- beta thalassaemia trait
- Normal pregnancy
- Autoimmune thrombocytopenic purpura
Rank potassium from high to low
a. hypothyroidism
b. addisons
c. ACTH dependent Cushing’s syndrome
d. Cushing’s disease
e. pheochromocytoma
- Addison’s disease (Primary Adrenal Insufficiency) – Highest potassium (hyperkalemia) due to aldosterone deficiency, leading to decreased potassium excretion.
- Hypothyroidism – Mildly high or normal potassium due to reduced renal clearance and decreased sodium-potassium ATPase activity.
- Pheochromocytoma – Variable potassium levels (normal, high, or low) depending on catecholamine effects, but hyperkalemia can occur in some cases.
- ACTH-dependent Cushing’s syndrome – Mildly low potassium (hypokalemia) due to excess cortisol and mineralocorticoid effects, leading to potassium wasting.
- Cushing’s disease (Pituitary-dependent Cushing’s) – Lowest potassium because chronically elevated ACTH stimulates excess cortisol, increasing renal potassium excretion more than ACTH-dependent Cushing’s syndrome.
Patient with hospital acquired pneumonia, rank from most to least likely organism
a. E.coli
b. Pseudomonas
c. Acinetobacter baumannii (?)
d. Candida Albicans
e. Coxiella burnetii
- Pseudomonas aeruginosa
- E. coli
- Acinetobacter baumannii
- Candida albicans
- Coxiella burnetii
Rank from largest to smallest vessel affected
a. Cerebral Giant cell arteritis
b. Polyarteritis nodosum
c. Capillaritis
d. Granulomatosis with polyangiitis
e. Takayasu arteritis
- Takayasu arteritis – Largest vessels (Affects the aorta and its major branches, including the subclavian, carotid, and renal arteries).
- Cerebral Giant Cell Arteritis (Temporal Arteritis) – Large to medium vessels (Primarily involves the external carotid branches, such as the temporal and ophthalmic arteries).
- Polyarteritis nodosa (PAN) – Medium vessels (Affects muscular arteries, such as renal, mesenteric, and coronary arteries; spares capillaries and venules).
- Granulomatosis with polyangiitis (Wegener’s) – Small vessels (Affects arterioles, venules, and capillaries, especially in the lungs, kidneys, and upper respiratory tract).
- Capillaritis – Smallest vessels (Primarily affects capillaries, leading to microscopic inflammation and bleeding).
