Correct Answer: A

Rationale: The correct answer is A: 'They may occur in minor illnesses.' Febrile seizures can occur even in minor illnesses, particularly in young children, and are often triggered by a rapid increase in body temperature. Choice B is incorrect because the cause of febrile seizures is not always readily identified. Choice C is incorrect as febrile seizures commonly occur in children between the ages of 6 months to 5 years, which includes the toddler years. Choice D is incorrect as febrile seizures are slightly more common in males than females.

Correct Answer: A

Rationale: In a newborn, a heart rate below 100 beats/min indicates the need for positive pressure ventilation to improve oxygenation. Providing blow-by oxygen or assessing skin condition/color may not address the primary issue of inadequate oxygenation due to the low heart rate. Starting chest compressions and contacting medical control is not warranted as the newborn is breathing spontaneously and only has a slightly low heart rate, which can be managed initially with positive pressure ventilations.

Correct Answer: B

Rationale: The correct answer is to limit screen time when preventing childhood obesity. Excessive screen time is associated with a sedentary lifestyle and can lead to increased consumption of unhealthy foods. Encouraging high-calorie snacks (choice A) contradicts the goal of preventing obesity. While fast food as an occasional treat (choice C) can be acceptable in moderation, it should not be encouraged as a preventive measure against obesity. Allowing the child to eat freely (choice D) without guidance can lead to overconsumption of unhealthy foods and contribute to obesity risk.

Correct Answer: B

Rationale: The primary purpose of a lumbar puncture is to obtain a sample of cerebrospinal fluid for analysis. This sample helps in diagnosing conditions such as meningitis by evaluating the presence of pathogens or abnormalities in the cerebrospinal fluid. Measuring the pressure of cerebrospinal fluid (Choice A) is not the main objective of a lumbar puncture, although it can be done during the procedure. Relieving intracranial pressure (Choice C) is not the direct purpose of a lumbar puncture, as other interventions are typically used for this purpose. Assessing the presence of infection in the spinal fluid (Choice D) is related to the overall goal of obtaining a sample for analysis, making it a secondary outcome of the procedure.

Correct Answer: C

Rationale: The correct priority intervention for a child with acute laryngotracheobronchitis is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can lead to airway obstruction, making it essential to have the equipment readily available in case of emergency. Padding the side rails, arranging for a quiet room, or obtaining a recliner for a parent are not the immediate priorities in managing a child with this condition.
