Correct Answer: D

Rationale: Retractions and the use of accessory respiratory muscles are signs of respiratory distress in infants. These clinical manifestations can be associated with trauma, such as shaken baby syndrome (SBS), which can lead to severe head injuries and respiratory compromise. Birth before 32 weeks' gestation (Choice A) is more related to prematurity complications rather than SBS. The absence of stridor and adventitious breath sounds (Choice B) may not be specific indicators of SBS. Previous episodes of apnea lasting 10 to 15 seconds (Choice C) alone may not be as concerning as the presence of retractions and use of accessory muscles in the context of a distressed infant.

Correct Answer: C

Rationale: The correct answer is C: Full-thickness burns involve the destruction of all layers of skin, extending into the subcutaneous tissue. This type of burn causes severe damage and loss of sensation due to nerve destruction. Choice A, erythema and pain, describes superficial burns (first-degree). Choice B, skin showing erythema followed by blister formation, describes partial-thickness burns (second-degree). Choice D, destruction injury involving underlying structures such as muscle, fascia, and bone, goes beyond the description of full-thickness burns.

Correct Answer: D

Rationale: Initiating pain assessment with a standardized pain scale is crucial in managing pain effectively during a sickle cell crisis. This step allows the nurse to objectively evaluate the child's pain level and tailor the pain management plan accordingly. Administering medication without a proper assessment could lead to inappropriate pain management. Using guided imagery and therapeutic touch may be beneficial as adjunct therapies but should not replace the initial pain assessment. Meperidine is not typically the first-line choice for pain management in sickle cell crisis due to its potential for neurotoxic metabolites.

Correct Answer: D

Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is to monitor for signs of infection. This is crucial to ensure that any potential infections are promptly identified and managed before surgery. Administering antibiotics, maintaining strict NPO status, and encouraging fluid intake are important interventions in various clinical situations but are not the priority in this scenario. Administering antibiotics may be part of the treatment plan but is typically prescribed by a physician. Maintaining NPO status is important to prevent complications related to anesthesia but may not directly address the specific needs of a child with appendicitis. Encouraging fluid intake is generally beneficial for hydration but may not be the primary concern before surgery for appendicitis.

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.
