Are most children with hypertension asymptomatic?

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: 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: A

Rationale: The correct answer is A: Water. Water is the ideal fluid to reconstitute oral rehydration salts because it helps in proper hydration without adding unnecessary sugars or acidity that may be present in fruit juice or soda. Using water ensures the salts are properly dissolved and can effectively rehydrate the individual. Choices B and C are incorrect because fruit juice and soda may contain sugars or acidity that can interfere with the rehydration process and are not recommended for reconstituting oral rehydration salts.

Correct Answer: B

Rationale: The correct answer is B. Increased urine output is not a warning sign of dehydration; it typically decreases with dehydration. Dehydration often presents with poor skin turgor, tachycardia, and an increased sensation of thirst (eager to drink) as the body tries to compensate for fluid loss. Choices A, C, and D are all correct warning signs of dehydration. Poor skin turgor is a result of decreased skin elasticity due to fluid loss. Tachycardia, an elevated heart rate, can be a compensatory mechanism to maintain cardiac output in dehydration. Feeling eager to drink is a common symptom of dehydration as the body attempts to restore fluid balance.

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.
