Explanation

Myositis ossificans typically affects muscles that undergo repetitive trauma or injury, such as:

• those in the thigh region
•  particularly the quadriceps muscles
•  brachialis muscles

Myositis ossificans can be seen at any age, though it is rare in children under 10  and is most common in adolescents and young adults

Explanation

Let's re-calculate the fluid requirement using the Parkland formula to confirm the fluid replacement for the first 12 hours.

The Parkland formula is:

Total fluid requirement in 24 hours = 4 x body weight in kg x % TBSA burned

For a 60 kg with 40% Total Body Surface Area (TBSA) burned:

1. Calculate the total fluid requirement for the first 24 hours:

Total fluid = 4 x 60 x 40

Total fluid = 9600 mL

2. Half of this amount is given in the first 8 hours.

3. The remaining fluid (4800ml) is given over the next 16 hours.

To find the fluid replacement for the first 12 hours:

First 8 hours: 4800 mL

Next 4 hours (which is one-fourth of the remaining 16 hours fluid)

Next 4 hours = 4800/4 = 1200 mL

Therefore, the total fluid replacement during the first 12 hours is:

First 8 hours + next 4 hours = 4800 mL + 1200mL = 6000 ML

So the fluid replacement during the first 12 hours for a burn patient weighing 60 kg and having 40% burns is 6000mL

$$Total fluid requirement in 24 hours=4×body weight in kg×%TBSA burnedTotal fluid requirement in 24 hours=4×body weight in kg×%TBSA burned

Explanation

Pinworm infection (Enterobiasis) is suspected, a common parasitic infestation in children presenting with perianal itching and potential weight loss due to discomfort

The disorder is spread by swallowing or inhaling the tiny eggs of the pinworm.

Explanation

Rheumatoid pneumoconiosis (RP) is also known as Caplan syndrome

It is swelling (inflammation) and scarring of the lungs.

It occurs in people with rheumatoid arthritis

Who has breathed in dust, such as from coal (coal worker's pneumoconiosis) or silica.

Explanation

Digoxin is the most readily absorbed oral cardiac glycoside.

It has a high oral bioavailability

Making it effective when administered orally for the treatment of various cardiac conditions.

Explanation

Kyphosis and scoliosis can be influenced by various factors, including posture and the type of furniture used by school children.

Poorly designed desks and chairs can contribute to poor posture, which may lead to these spinal deformities.

Explanation

A normal potassium level for adults is between 3.5 and 5.5 millimoles per liter (mmol/L).

Potassium level is high (also called hyperkalemia) when it goes above 5.5 mmol/L.

Explanation

Magnesium sulfate is a drug commonly used to control fits (seizures) in a pregnant lady Particularly in cases of eclampsia and severe preeclampsia.

It acts as an anticonvulsant and helps prevent seizures in these conditions.

Explanation

Rosette formation is characteristic of retinoblastoma.

Retinoblastoma typically displays specific types of rosettes

The formation of highly organized Flexner-Wintersteiner rosettes is a characteristic of retinoblastoma 

That occurs only rarely in other neuroblastic tumors and represents cellular differentiation toward retinal tissue.
