The viral pathogen that frequently causes acute diarrhea in young children is:
Rotavirus.
Salmonella organisms.
Shigella organisms.
Giardia organisms.
The Correct Answer is A
The correct answer is choice A: Rotavirus.
Choice A rationale:
Rotavirus is a viral pathogen that frequently causes acute diarrhea in young children. It is highly contagious and is responsible for a significant portion of severe diarrhea cases worldwide. Rotavirus infections are most common in infants and young children, and they can lead to dehydration, especially in developing countries where access to clean water and proper sanitation might be limited.
Choice B rationale:
Salmonella organisms can cause food poisoning and gastrointestinal infections that lead to diarrhea. However, they are more commonly associated with bacterial infections rather than viral-induced acute diarrhea.
Choice C rationale:
Shigella organisms are also bacterial pathogens that cause diarrhea, specifically bacillary dysentery. While they can cause severe diarrhea, they are not the viral pathogen typically responsible for acute diarrhea in young children.
Choice D rationale:
Giardia organisms are parasites that can cause gastrointestinal infections leading to diarrhea. However, they are not viruses, and they are less commonly associated with acute diarrhea in children compared to rotavirus.

Correct Answer is C
Explanation
The correct answer is choice C.
Choice C rationale:
Placing the avulsed tooth in cold milk is the most suitable medium for transporting it to the dentist. Cold milk helps preserve the viability of the tooth's cells and tissues, which is crucial for successful reimplantation. The temperature and composition of cold milk provide a suitable environment to prevent cell damage.
Choice A rationale:
Placing the tooth in a dry, clean jar is not recommended. A dry environment can cause the tooth's cells to dry out and become nonviable, making reimplantation less successful.
Choice B rationale:
Warm salt water is not the optimal choice for transporting an avulsed tooth. Warm water can cause damage to the tooth's cells, and salt water may not provide the necessary conditions to maintain the tooth's viability.
Choice D rationale:
Placing the tooth in cold water might seem logical, but it is not as effective as cold milk. Cold water lacks the protective properties and nutrients that milk provides, potentially leading to a higher risk of cell damage in the avulsed tooth.
Correct Answer is B
Explanation
The correct answer is choice B. A feeling of fullness in the ear.
Choice A rationale:
Nausea and vomiting are not typical symptoms of chronic otitis media with effusion (OME). OME involves fluid accumulation in the middle ear without signs of acute infection. It is commonly seen in children and may cause mild hearing impairment and a feeling of fullness in the ear.
Choice B rationale:
A feeling of fullness in the ear is a common symptom of OME. The fluid accumulation in the middle ear can lead to a sensation of pressure or fullness, as well as mild hearing loss. This can impact a child's ability to hear and communicate effectively.
Choice C rationale:
Severe pain in the ear is more characteristic of acute otitis media (AOM), which is an infection of the middle ear with signs of inflammation. In OME, pain is typically not a prominent symptom unless there is an underlying AOM episode.
Choice D rationale:
Fever as high as 40°C (104°F) is not a typical symptom of OME. OME is generally a chronic condition without acute signs of infection such as fever. However, if a fever is present, it might indicate a concurrent infection that needs further evaluation.
