Rationale: Encouraging the adolescent to remain in the room throughout the hospitalization may lead to social isolation, hinder the adolescent's emotional well-being, and impede their recovery. It is essential for adolescents to have social interaction, engage in meaningful conversations, and receive support from peers to cope with the stress of hospitalization. Choices A, B, and D are appropriate interventions as they promote involvement in care, emotional expression, and social support, which are beneficial for the adolescent's overall well-being during hospitalization.

Correct Answer: A

Rationale: The statement is true. In many cases, children with hypertension do not show any symptoms, making it challenging to diagnose them. Regular blood pressure checks are crucial to detect hypertension early, as it can have serious health implications if left untreated. Choice B is incorrect because most children with hypertension do not exhibit symptoms, hence being asymptomatic. Choices C and D are empty as they do not provide additional options.

Correct Answer: A

Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.

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.

Correct Answer: C

Rationale: Inability to lie supine is a characteristic sign of lower respiratory infection. This positioning preference is often seen in patients with lower respiratory infections due to discomfort or difficulty breathing when lying flat on their back. While cough and fever are common symptoms associated with respiratory infections, they are not specific to lower respiratory infections. Inability to eat may indicate general illness or discomfort but is not a specific indicator of lower respiratory infection.
