Q

What is the reason why serum creatinine is a better guage of GFR than BUN?

A

Creatinine is useful for estimating GFR because it is a small, freely filtered solute that is not reabsorbed by the tubules.
PCr levels can increase acutely from dietary ingestion of cooked meat, however, and creatinine can be
secreted into the proximal tubule through an organic cation pathway (especially in advanced progressive chronic kidney disease), leading to overestimation of GFR.

Q

Enzymes that reflect cholestasis

A

16
Q

These changes in lean body mass largely reflect the age-dependent decline in growth
hormone secretion and, consequently, circulating levels of

A

insulin like growth factor type I (IGF-I) that occur with normal aging.

17
Q

30/F complained of weakness in afternoon and improves with rest. Fatigued on repetitive actions. On PE, reflex intact, no sensory deficit. Unable to sustain movements.

A

Myasthenia Gravis
Neuro Muscular Junction

Fatigable weakness is suggestive of disorders of the neuromuscular junction, which cause functional loss of muscle fibers due to failure of their activation.

18
Q

Refers to an inherently subjective human experience of physical and mental weariness, sluggishness,
and exhaustion.

In the context of clinical medicine, it is
most typically and practically defined as difficulty initiating or maintaining
voluntary mental or physical activity

A

Fatigue

19
Q

Area of abdomen will referred pain T10

A

T10 umbilicus

20
Q

Mechanism of glucocorticoid as an antipyretic agent

A

As effective antipyretics, glucocorticoids act at two levels

  1. Reduce PGE2 synthesis by inhibiting the activity of phospholipase A2, which is needed to release arachidonic acid from the cell membrane
  2. block the transcription of
    the mRNA for the pyrogenic cytokines.
21
Q

A false-positive dipstick for hematuria (where no RBCs areseen on urine microscopy) may occur when

A

myoglobinuria is present, often in the setting of rhabdomyolysis.
