Explanation

After gastrectomy, malabsorption is a common condition

That may occur due to the reduced capacity of the digestive system to properly absorb nutrients.

Impaired digestion and nutrient absorption occur without the stomach, leading to malabsorption syndromes.

Explanation

For high‐risk GTN, EMA/CO is the most commonly used first‐line therapy, with platinum‐etoposide combinations

EMA/CO therapy consists of the combination of etoposide, methotrexate, and actinomycin D, along with cyclophosphamide and vincristine.

Explanation

Arterial pH remains relatively stable during pregnancy

Reflecting the effective regulation of acid-base balance by the body's homeostatic mechanisms.

During pregnancy, the respiratory system changes to accommodate the needs of the fetus while arterial pH typically remains stable.

These include:

• increased oxygen consumption
• alterations in lung volumes
• adjustments in respiratory mechanics

Explanation

The statement that is not correct regarding snake bites is The type of first aid given to the victim will decide the severity of the outcome.

The first aid given may help in stabilizing the victim temporarily but does not ultimately determine the severity of the outcome.

While prompt and appropriate first aid can help mitigate the effects of a snake bite,

the severity of the outcome is influenced by various factors including:

• the type of snake
• the amount of venom injected
• the location of the bite
• the size and health of the victim
• the availability and timeliness of medical treatment.
  

Explanation

Immunization against hepatitis B also protects against hepatitis D (HDV) infection.

Hepatitis D virus can only infect individuals who are already infected with hepatitis B.

Therefore, vaccination against hepatitis B also prevents hepatitis D infection, as the hepatitis B surface antigen is necessary for the HDV to replicate.

Explanation

Acute fatty liver of pregnancy (AFLP) can cause liver failure

It happens when too much fat builds up in your liver when you're pregnant.

It's a medical emergency and involves delivering the fetus as soon as possible.

It is a serious condition that typically occurs in the third trimester of pregnancy

Explanation

Conjunctival follicles are commonly associated with Trachoma

Trachoma is a chronic conjunctivitis caused by Chlamydia trachomatis infection. Conjunctival follicles are a hallmark feature of trachoma

And are often seen on the inner surface of the eyelids and the conjunctiva.

Explanation

The inspiratory center is situated in the upper part of the medulla oblongata.

This area is crucial for regulating the rhythm of breathing.

It is composed of a group of neurons (the dorsal respiratory group).

While the centers in the pons assist in regulating and fine-tuning the breathing process

Explanation

The mechanism that is not primarily involved in promoting venous return is Parasympathetic stimulation.

Parasympathetic stimulation influences the heart rate and, to some extent, vascular tone

It mainly affects cardiac function rather than the mechanisms involved in returning blood to the heart from the periphery.

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.
