Correct Answer: B

Rationale: The correct answer is B - Rotavirus. Rotavirus vaccine is available to prevent diarrhea in children. Rotavirus is a common cause of severe diarrhea in infants and young children globally, and vaccination has been shown to be effective in reducing the burden of this disease. Choices A and C are incorrect because there is no specific vaccine available for Adenovirus or Enterovirus to prevent diarrhea in children. Choice D is incorrect because while vaccines are available for some viruses that can cause diarrhea in children, not all mentioned in the choices have a specific vaccine available.

Correct Answer: D

Rationale: The correct instruction for circumcision care is to use warm water to gently clean the penis during diaper changes. Alcohol wipes should be avoided as they can cause irritation. Yellowish exudate around the head of the penis is a normal part of the healing process and does not require reporting unless accompanied by other concerning symptoms. Avoiding petroleum jelly on the circumcision site is important to prevent trapping moisture and bacteria, which can lead to infection.

Correct Answer: C

Rationale: Cabbage is an example of a goitrogen that should be avoided in children with hypothyroidism. Goitrogens are substances that can interfere with thyroid function by inhibiting iodine uptake, potentially worsening the condition. Cabbage, along with other cruciferous vegetables like broccoli and cauliflower, contains compounds that can affect thyroid hormone production. Oranges, tomatoes, and grapes are not classified as goitrogens. Therefore, it is important for parents to be aware of foods like cabbage and to limit their child's intake to help manage their hypothyroidism effectively.

Correct Answer: A

Rationale: Allergy is the correct answer as it is a non-infectious cause of diarrheal diseases. While bacterial, parasitic, and viral infections can lead to diarrhea by affecting the gastrointestinal tract, allergies are immune system reactions triggered by specific substances and are not caused by infectious agents. Bacterial, parasitic, and viral infections are known to cause infectious diarrhea, making choices B, C, and D incorrect.

Correct Answer: D

Rationale: When a child is suffering from diarrhea, it is essential to continue breastfeeding day and night to maintain hydration and provide necessary nutrients. Stopping formula milk for 6 hours (choice B) is not the recommended approach as it may lead to a lack of essential nutrients during this critical time. Giving breast milk together with oral rehydration salts (choice C) can help replenish lost fluids and electrolytes, making it a suitable recommendation. Therefore, advising the mother to follow both options A and C is the most appropriate approach to manage the child's condition effectively.
