Food energy is commonly expressed in kilocalories and in what other unit?

Correct Answer: A

Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.

Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.

Rationale: The correct answer is B: Ensuring access to emergency medications. In a school setting, it is crucial to have emergency medications available for a child with asthma in case of an asthma attack. This helps in managing asthma effectively and promptly. Choices A, C, and D are incorrect because limiting physical activity, reducing the number of classes attended, and avoiding interaction with other students are not recommended strategies for managing asthma in a school setting. Encouraging physical activity, ensuring regular attendance, and promoting social interactions are important for the overall well-being of a child with asthma.

Rationale: The primary goal of managing diabetes mellitus in children is to ensure normal growth and development. This involves maintaining stable blood glucose levels to prevent complications. Option A is incorrect because promoting weight gain is not a primary goal in managing diabetes; rather, the aim is to maintain a healthy weight. Option B is not the primary goal; although it is important to prevent episodes of hypoglycemia, the main focus is on overall management. Option D is incorrect as optimizing blood sugar control is a means to achieve the primary goal, which is ensuring normal growth and development.

Correct Answer: B

Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants.

Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.
