Explanation

The diagnostic test typically used for rheumatic fever is ASO (Anti-streptolysin O) titer.

Rheumatic fever is an autoimmune inflammatory disease

That can develop after a group A streptococcal infection, such as strep throat. 

The ASO titer measures the antibodies produced in response to a recent streptococcal infection.

Elevated ASO titers indicate recent streptococcal infection and are a key diagnostic marker for rheumatic fever.

Explanation

The presence of blood-stained and foul-smelling nasal discharge can indicate an infection or irritation caused by the rhinolith.

If someone experiences these symptoms, it's essential to consult a healthcare professional for proper diagnosis and treatment.

Explanation

The infraorbital nerve is not a branch of the ophthalmic nerve

it is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)).

It arises in the pterygopalatine fossa.

It passes through the inferior orbital fissure to enter the orbit.

Explanation

At the beginning of forced expiration Lung elastic recoil increases

During forced expiration, the muscles of respiration contract to actively decrease the volume of the thoracic cavity.

However, at the beginning of forced expiration, the lung elastic recoil, which is the natural tendency of the lungs to recoil inward, increases.

This recoil helps to push air out of the lungs by reducing the volume of the thoracic cavity.

Explanation

The appropriate statement regarding a medico-legal certificate is It is a document relevant to the cause of death.

A medico-legal certificate typically includes:

• information relevant to the cause of death
• detailing medical findings, circumstances
• factors contributing to the individual's demise.

It serves as an official record and may be used for legal or administrative purposes, such as:

• inquests
• insurance claims
• legal proceedings

Explanation

Tracheostomy is typically performed just below the cricoid cartilage,

between the 2nd and 4th tracheal rings.

This location provides access to the trachea

while minimizing the risk of injury to vital structures

such as the thyroid gland and major blood vessels.

Explanation

The true statement about Acute Myeloid Leukemia (AML) among the options provided is More than 20% blasts for diagnosis.

AML is characterized by the proliferation of myeloid precursor cells (blasts) in the bone marrow, typically comprising more than 20% of the nucleated cells.

Explanation

Malabsorption due to a mucosal intestinal defect is commonly associated with celiac disease.

Even though celiac disease typically damages the upper part of the small intestine (duodenum), the entire small bowel can be affected.

This damage results in malabsorption of nutrients, leading to symptoms such as diarrhea, weight loss, fatigue, and deficiencies in vitamins and minerals.

Explanation

Fluorescent microscopy is not typically used for the direct detection of serum autoantibodies.

Instead, techniques such as enzyme-linked immunosorbent assay (ELISA) or immunofluorescence assays (IFA) using serum samples are more commonly employed.

Fluorescent microscopy is used for various purposes in medicine, particularly in the diagnosis and study of diseases.

Explanation

Chlamydial infection, especially if it leads to inflammation or scarring of the fallopian tubes, increases the risk of an ectopic pregnancy.

This is because the scarring or damage to the fallopian tubes can hinder the normal passage of a fertilized egg from the fallopian tube to the uterus

Leading to the implantation of the embryo outside of the uterus

Typically in the fallopian tube (which is characteristic of ectopic pregnancy).

*

The other options listed do not directly increase the risk of ectopic pregnancy.
