Medicine MCQs-8 : Frostbite
Snow blindness is produced by -
Snow blindness is produced by ultraviolet (UV) solar radiation reflected from snow, ice, or water. It tends to be more common at high altitudes, where the air filtration of UV radiation is diminished.
“chunk of wood” sensation in the extremity is seen in -
Frost bite - “chunk of wood” sensation in the extremity
Most imminent threat to life in cold injuries is -
Systemic hypothermia - When hypothermia is identified, treatment should be instituted immediately with both passive and active rewarming measures
All of the following is non-freezing cold injury EXCEPT ?
Local cold injuries may be divided into freezing (frostbite) and nonfreezing (chilblains and immersion [trench] foot) injuries.
Mildest form of peripheral cold injury is frostnip
Mildest form of peripheral cold injury is -
The mildest form of peripheral cold injury is frostnip, which tends to occur in apical structures (nose, ears, hands, feet), where blood flow is most variable because of the richly innervated arteriovenous anastomoses.

Medicine MCQs – 7
Which of the following is most common type of kidney stone?
Calcium oxalate: The most common type of kidney stone
High dietary intake of potassium appears to reduce the risk of stone formation because potassium promotes the urinary excretion of citrate, an inhibitor of calcium crystal formation.
Randall's plaque is microscopically a plaque of -
Randall's plaque is microscopically a plaque of calcium deposited in the interstitial tissue of the renal papilla. These plaques are thought to serve as a nidus for urinary stone formation. Large amounts of Randall's plaque are unique to idiopathic calcium oxalate stone formers.
Which of the following microorganism is not associated with struvite stone formation in urinary tract.
Struvite stones are formed by urinary tract infection with urease producing bacteria that splits urea to ammonium, and increases urine pH to neutral or alkaline values.
Organisms splitting urea are Proteus, Pseudomonas, Klebsiella, Staphylococcus, and Mycoplasma.
E coli is not associated with struvite stones
Which of the following is used to differentiate between phleboliths and ureteric stone ?
"rim sign " - rim, ring, or halo of soft tissue visible on CT scans that completely surrounds ureteral stones.
The effect is enhanced by the local inflammation a stone produces in the ureteral wall, with subsequent edema at the site of the calculus.
The rim sign is generally missing or incomplete with phleboliths.
Urease-positive bacteria increase chances of which of the following stone formation?
Urease-positive bacteria, such as Proteus mirabilis can produce the enzyme urease, which converts urea to ammonia and carbon dioxide.
This increases the urinary pH and promotes struvite stone formation.
Which of the following stone formation is promoted by the alkaline urine (pH >7.2) and the presence of ammonia in the urine?
Two conditions must coexist for the formation of struvite calculi. These are (1) alkaline urine (pH >7.2) and (2) the presence of ammonia in the urine.
Struvite stones are also known as triple-phosphate (3 cations associated with 1 anion), infection (or infection-induced), phosphatic, and urease stones.
All of the following true for Struvite stone EXCEPT ?
Struvite readily forms in alkaline conditions.
Potentiated by alkaline urine and high magnesium excretion
If a stone grows to more than ----- millimeters, it can cause blockage of the ureter
5 mm
Which of the following is the diagnostic method to detect kidney stones?
helical CT scan with 5 millimeters (0.2 in) sections is the diagnostic method to use to detect kidney stones and confirm the diagnosis of kidney stone disease
Adding contrast to the CT scan study may sometimes help clarify a difficult or confusing case but in general, contrast obscures calcific densities and as such, contrast scans are usually only indicated during subsequent evaluation of patients with stones.
The noncontrast CT is the cornerstone of initial radiographic assessment.
What is the composition of Jackstone calculus?
Jackstone calculi - almost always composed of calcium oxalate dihydrate and consist of a dense central core and radiating spicules.
