Correct Answer: A

Rationale: The priority nursing action when a child with a suspected fracture is brought to the emergency department is to immobilize the affected limb. Immobilization helps prevent further injury until a fracture is confirmed or ruled out. Applying ice or elevating the limb can wait until after immobilization has been achieved. Checking the child's neurovascular status is important but is not the priority action in this situation.

Correct Answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.

Correct Answer: D

Rationale: Initiating pain assessment with a standardized pain scale is crucial in effectively managing pain during a sickle cell crisis. This initial step helps the nurse understand the severity of the pain, which guides subsequent interventions. Administering medications, such as NSAIDs or meperidine, should only be done after a thorough pain assessment to ensure appropriate and individualized treatment. Using guided imagery and therapeutic touch may be beneficial as adjunct interventions, but they should not replace the essential first step of assessing the pain level accurately.

Correct Answer: B

Rationale: The most appropriate time for a child to first visit the dentist is within the next few months after turning two years old. This visit allows the dentist to assess the child's oral health, provide guidance on proper oral hygiene practices, and establish a positive relationship with dental care. Choice A (Before starting school) is not as specific and timely as the recommended age of 2 years. Choice C (When the first deciduous teeth are lost) is not ideal as preventive dental visits should start earlier to establish good oral health habits. Choice D (At the next dental check-up for a family member) may delay the child's first dental visit, missing the opportunity for early preventive care and guidance.

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.
