the frontal fontanell is protruding when a child suffering from:

Correct Answer: D

Rationale: The protrusion of the frontal fontanelle in a child can be a concerning sign and can be seen in various conditions such as meningitis, hydrocephalus, and subdural hematoma. In meningitis, the inflammation of the meninges can lead to increased intracranial pressure, which may cause the fontanelle to bulge. Hydrocephalus, which is the buildup of fluid in the brain, can also result in the fontanelle being more pronounced. Additionally, a subdural hematoma, which is a collection of blood between the brain and its outermost covering, can lead to pressure on the brain and consequent fontanelle protrusion. Therefore, all the provided choices (A, B, C) are correct as they can lead to the protrusion of the frontal fontanelle in a child.

Correct Answer: B

Rationale: The current recommendations for hepatitis B (HBV) vaccine state that the first dose should be administered between ages 12 and 15 months. The vaccine series typically consists of three doses, with the second dose administered 1-2 months after the first dose, and the third dose given at least 8 weeks after the second dose. This schedule is recommended by the Centers for Disease Control and Prevention (CDC) to provide optimal protection against the hepatitis B virus. Starting the vaccine series at 12-15 months ensures that the child's immune system is mature enough to respond effectively to the vaccine and generate lasting immunity.

Correct Answer: D

Rationale: Cellulitis is a common skin infection that is often caused by bacteria, primarily Streptococcus or Staphylococcus organisms. These bacteria typically enter the skin through a crack or break, such as a cut, insect bite, or scratch. Once inside the skin, they can cause inflammation and infection, leading to symptoms such as redness, warmth, swelling, and tenderness in the affected area. Prompt treatment with antibiotics is essential to clear the infection and prevent complications.

Correct Answer: B

Rationale: The child with chickenpox is considered to be no longer contagious when the lesions are crusted over. This usually occurs around 7-10 days after the rash first appears. At this stage, the fluid-filled blisters have dried up and formed scabs, indicating that the infectious stage of the illness has passed. The child can then safely return to school or daycare without posing a risk of spreading the infection to others. It is important for parents and caregivers to continue practicing good hygiene and ensuring that the child does not scratch the scabs to prevent complications and scarring.
