Correct Answer: D

Rationale: Enteric fever, caused by Salmonella typhi or paratyphi, is characterized by a continuous fever pattern. The fever typically persists without significant fluctuations, distinguishing it from diseases with intermittent or relapsing fever patterns. Pel-Ebstein fever, a cyclic pattern of fever seen in Hodgkin's lymphoma, is not associated with enteric fever. Relapsing fever is a characteristic of diseases like Borrelia recurrentis infection. Intermittent fever is seen in conditions like malaria.

Correct Answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.

Correct Answer: C

Rationale: Encouraging the adolescent to remain in the room throughout the hospitalization to ensure adequate rest periods is not appropriate. It is crucial for adolescents to have opportunities for physical activity and social interaction to promote their well-being during hospitalization. Allowing them to assist with procedures when possible can empower them and provide a sense of control. Encouraging discussions about their thoughts and feelings helps address their emotional needs. Facilitating peer visitation fosters social support, which is beneficial for their well-being. Therefore, choice C is the least appropriate as it restricts important aspects of the adolescent's development and coping mechanisms during hospitalization.

Correct Answer: A

Rationale: Beta-adrenergic agonists like Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

Correct Answer: B

Rationale: The correct answer is B. Avoiding exercise entirely is not recommended for asthma management. Regular exercise can actually help strengthen the lungs and improve overall respiratory function. Teaching should focus on appropriate exercise routines that are suitable for individuals with asthma to prevent attacks. Choices A, C, and D are all appropriate and indicate good understanding of asthma management. Increasing fluid intake helps thin secretions, using the bronchodilator inhaler before the steroid inhaler follows the correct order of inhaler administration, and identifying triggers is essential for asthma control.
