Correct Answer: B

Rationale: Auscultating the heart and lungs while the infant is held is the most appropriate intervention to assess his current condition. This action allows the nurse to gather important information regarding the cardiovascular and respiratory status of the infant, which is crucial in evaluating his post-surgical recovery and overall well-being. Option A is incorrect as stimulating the infant to cry intentionally is not necessary and could cause distress. Option C is incorrect as the infant's growth is within the expected range, indicating no signs of failure to thrive. Option D is incorrect as obtaining a 12-lead electrocardiogram is not the initial intervention needed in this situation; assessing the heart and lungs through auscultation is more immediate and informative.

Correct Answer: C

Rationale: Monitoring for signs of infection at the surgical site is crucial after an appendectomy as it helps in early detection and treatment of any potential complications. This intervention is essential for ensuring the child's proper healing and recovery post-surgery. Encouraging early ambulation is generally beneficial post-operatively but may not be the priority immediately after an appendectomy. Applying warm compresses to the incision site may not be indicated as it can increase the risk of infection. Providing a high-fiber diet immediately post-op is not recommended as the digestive system needs time to recover from surgery.

Correct Answer: B

Rationale: The priority action for the nurse when a client with meningitis presents with a severe headache and photophobia is to place the client in a dark, quiet room. This intervention helps reduce stimuli that can exacerbate symptoms such as headache and photophobia. Creating a calm environment can provide relief and promote comfort for the client while also supporting their recovery. Administering pain medication may be necessary but ensuring a suitable environment takes precedence. Notifying the healthcare provider is important but is not the immediate priority. Encouraging rest is beneficial, but creating an appropriate environment to alleviate symptoms is the initial essential step.

Correct Answer: A

Rationale: The correct answer is A: 'We should monitor our child's growth and appetite regularly.' Correct monitoring of the child's growth and appetite is crucial when a child is on ADHD medications, especially stimulants, as these medications can have side effects related to growth and appetite. Monitoring these parameters regularly helps in assessing the medication's impact and making any necessary adjustments. Choices B, C, and D are incorrect: B talks about drowsiness, C mentions avoiding stomach upset, and D refers to increased urination and limiting fluid intake. While these are potential side effects of medications, they do not directly address the importance of monitoring growth and appetite, which is crucial in children on ADHD medications.

Correct Answer: A

Rationale: The correct intervention for a child with Kawasaki disease, presenting with irritability and skin peeling, is to place the child in a quiet environment. This helps reduce environmental stimuli, calming the child and aiding in managing the symptoms associated with the disease. Choice B is incorrect as addressing food preferences is not the priority in this situation. Choice C is incorrect as the focus should be on the child's immediate needs. Choice D is incorrect as applying lotion is not the first-line intervention for Kawasaki disease symptoms.
