Correct Answer: C

Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.

Correct Answer: B

Rationale: In typhoid fever, the rash typically appears on the third day after symptoms first appear. This rash can help in diagnosing the disease along with other symptoms such as fever, malaise, and abdominal pain. Choices A, C, and D are incorrect because the rash in typhoid fever usually appears on the third day, not the second, fourth, or seventh day after the symptoms begin.

Correct Answer: A

Rationale: The correct answer is A: 'The child vomits everything.' Vomiting everything is considered a danger sign in a child as it can lead to dehydration and other serious complications. Recognizing this sign early can help in timely intervention and management of the child's condition. Choices B and C are incorrect as diarrhea and headache, while concerning, are not specific danger signs highlighted in the Integrated Management of Neonatal and Childhood Illnesses.

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: In this scenario, the priority is to assess the child's vital signs first, including heart rate, respiratory rate, and blood pressure. These data will provide critical information on the child's current physiological status and guide further interventions. Option B, recent exposure to communicable diseases, is not the priority in an acute ingestion situation. Option C, number of immunizations received, and option D, height and weight, are important but not as critical as assessing vital signs in this immediate situation.
