What is the typical serum albumin level seen in the nephrotic syndrome?
1) > 4 g/dL
2) 3.0-3.5 g/dL
3) < 3.0 g/dL
4) 2.0-2.5 g/dL
The nephrotic syndrome is characterized by hypoalbuminemia, with serum albumin levels typically less than 3 g/dL due to the loss of albumin in the urine.
Presence of cavitation in TB indicates the disease is
1) Active
2) Inactive
3) Persistent
4) Super infection
General Medicine
Answer: 1
Presence of cavitation in TB indicates the disease is active
What is the typical location of Cushing's ulcers in the digestive tract?
1) Duodenum
2) Jejunum
3) Ileum
4) Stomach
Cushing's ulcers are typically found in the stomach, often along the lesser curvature or the anterior wall, and are associated with increased gastric acid secretion secondary to excessive vagal stimulation due to intracranial lesions.
In which of the following conditions is the prevalence of nephrotic syndrome more common in children than in adults?
1) Membranous nephropathy
2) Minimal-change disease
3) Focal segmental glomerulosclerosis
4) Membranoproliferative glomerulonephritis
Minimal-change disease is the most common cause of nephrotic syndrome in children, with a prevalence of 65%. In contrast, it is less common in adults, affecting only 10% of cases.
A 45-year-old male presents with severe epigastric pain radiating to the back, nausea, vomiting, and malaise after consuming a large meal at a buffet. His stool is watery and non-bloody. His blood pressure is normal. Which of the following is the most likely diagnosis?
1) Peptic ulcer
2) Gallstones
3) Pancreatitis
4) Clostridium perfringens food poisoning
The rapid onset of symptoms after a large meal at a buffet, along with the presence of severe epigastric pain and watery diarrhea, suggests a gastrointestinal infection. Clostridium perfringens is a common cause of foodborne illness and typically presents within 8 to 16 hours of ingestion. The condition is usually self-limiting and improves with supportive care.
Which of the following is NOT a component of the intrinsic pathway of the coagulation cascade?
1) Factor XII
2) Factor XI
3) Tissue factor
4) Factor X
Tissue factor is actually a component of the extrinsic pathway of the coagulation cascade. The intrinsic pathway involves factors XII, XI, prekallikrein, high molecular weight kininogen, and factors VIII, IX, and X.
What is the principal function of ceruloplasmin in the body?
1) Transport of iron
2) Transport of copper
3) Inhibition of serum proteases
4) Osmotic regulation
Ceruloplasmin is a protein synthesized in the liver and is the major copper-transporting protein in the bloodstream. It is essential for the maintenance of iron homeostasis and the metabolism of iron and copper.
Which of the following is NOT a type of E. coli associated with diarrheal disease?
1) Enterotoxigenic E. coli (ETEC)
2) Enteropathogenic E. coli (EPEC)
3) Enterohemorrhagic E. coli (EHEC)
4) Enteroaggregative E. coli (EAEC)
ETEC, EIEC, and EAEC are all types of E. coli that can cause diarrheal disease through various mechanisms. EPEC is typically associated with gastrointestinal illness, particularly in children, but does not typically cause the severe forms of diarrhea seen with ETEC or EHEC.
