1. Sickle cell anaemia
2. Niemann-pick disease
3. Letterer-Siwe disease
4. Hand-Schuller-Christian disease
Oral Pathology
Answer: 4
Diabetes insipidus, exophthalmos, and radiolucent bone defects suggest Hand-Schuller-Christian disease.
Quantity of the X-ray beam is governed by
1. kVp
2. mAs
3. Filament current
4. Length of the X-ray tube
Oral Pathology
Answer: 1
Quantity of the X-ray beam is governed by mAs (milliampere-seconds).
Which of the following cell types show abnormal function when there is a history in a young adult of multiple arm and leg fractures following minor falls?
1) Granulocytic stem cells
2) Megakaryocytes
3) Plasma cells
4) Osteoclasts
Osteoclasts show abnormal function in conditions leading to multiple fractures, as they are responsible for bone resorption.
When a shielded open cone is used the gonadal dose to a patient is mainly from
1. Leakage from tube
2. Primary X-ray tube
3. Scatters from patient"s face
4. All of the above
Oral Pathology
Answer: 3
The gonadal dose mainly comes from leakage from the tube when using a shielded open cone.
In thalassemia the microscopic picture of RBCs is:
1. Microcytic, hypo chromic and target cells present
2. Macrocytic, hypochromic and target cell present
3. Microcytic. hypochromic and target cell absent
4. Macrocytic. hypochromic and target cells absent
Pathology
Answer: 1
Mcroscopic picture of red blood cells (RBCs) in thalassemia, the following
characteristics are typically observed:
Microcytic: The RBCs are smaller than normal (microcytic)
due to the reduced hemoglobin content.
Hypochromic: The RBCs have a lower concentration of
hemoglobin, leading to a paler appearance (hypochromic).
Target cells: These are RBCs that have a bullseye
appearance due to an abnormal distribution of hemoglobin within the cell.
Target cells are often seen in thalassemia due to the imbalance of globin
chains and the resultant membrane changes.
Which of the following is a common complication of hyperparathyroidism?
1) Osteoporosis
2) Osteopetrosis
3) Renal stones
4) Hypoparathyroidism
A common complication of hyperparathyroidism is the formation of renal stones due to elevated calcium levels in the urine.
Adamantinoma is
1. A tumour from embryonal cell of developing teeth
2. Also known as ameloblastoma
3. Is a complication of dengigerous cyst
4. All of these
Oral Pathology
Answer: 4
Adamantinoma is a rare neoplasm and it is indeed associated with the teeth, but it is not synonymous with ameloblastoma, and it is not exactly a complication of dentigerous cysts. However, since all options are somewhat inaccurate or misleading, your answer indicates that you may be looking for the one best fitting choice.
Hereditary spherocytosis is due to deficiency -
1) Spectrin
2) Invertin
3) Cytokeratin
4) All of the above
General Pathology
Answer: 1
Hereditary spherocytosis is primarily due to a deficiency of spectrin, a protein that helps maintain the integrity of the red blood cell membrane.
