A 3-year-old boy is brought to the emergency department by his mother. He is lethargic, with retractions and nasal flaring. He has a respiratory rate of 70/min, with warm extremities and brisk capillary refill. Which immediate life-threatening condition could this child’s condition most likely progress to if left untreated?

In management of post–cardiac arrest patients, extra care should be taken to avoid reperfusion injury. What should the ideal oxygen saturation range most likely be?

Use this scenario to answer questions 36-37:You are caring for a 5-year-old boy with a 4-day history of high fever and cough. He is having increasing lethargy, grunting, and sleepiness. Now he is difficult to arouse and is unresponsive to voice commands. His oxygen saturation is 72% on room air and 89% when on a nonrebreathing oxygen mask. He has shallow respirations with a respiratory rate of 38/min. Auscultation of the lungs reveals bilateral crackles. What assessment finding is consistent with respiratory failure in this child?  

A 5-year-old child is brought to the emergency department by ambulance after being involved in a motor vehicle collision. You are using the primary assessment to evaluate the child. When assessing the child’s neurologic status, you note that he has spontaneous eye opening, is fully oriented, and is able to follow commands. How would you document this child’s AVPU (Alert, Voice, Painful, Unresponsive) Pediatric Response Scale finding?

Use this scenario to answer questions 34-39: A 51-year-old patient is reporting stomach pain and chest discomfort that is radiating down their left arm. The patient had coronary artery stents placed 5 days ago. The patient’s skin is pale and cool to the touch. Their blood pressure is 72/46 mm Hg, mean arterial pressure is 55 mm Hg, heart rate is 188/min, respiratory rate is 28 breaths per minute, and SpO2 is 89% on room air. The ECG shows ventricular tachycardia. While you administer supplemental oxygen, the patient suddenly loses consciousness, and the ECG monitor shows ventricular fibrillation. Which would you have done first if the patient had not gone into ventricular fibrillation?

Submission Guidelines File Name: Name your submission file strictly ArrayFilter.cpp. Single-File Requirement: Include all #include directives, function prototypes, main(), and your function definition in this single .cpp file. Compilation: Code must compile cleanly under C++17 (g++ -std=c++17 -Wall Lab_ArrayFilter.cpp -o Lab_ArrayFilter). Write a function named displayGreaterThan that accepts three arguments: An array of integers (const int arr[]) The size of the array (int size) A baseline comparison value n (int n) The function should iterate through the array and display every number in the array that is strictly greater than n. Write a main() function that acts as a test driver: Define a test array with at least 8 elements (e.g., {14, 3, 27, 8, 42, 19, 5, 30}). Prompt the user to enter a value for n. Call displayGreaterThan to output the results. Example output: Test Array: [14, 3, 27, 8, 42, 19, 5, 30] Enter a number (n): 15 Numbers greater than 15: 27 42 19 30

An 8-year-old child is brought to the emergency department by his mother for difficulty breathing. He has a history of asthma and nut allergies. His mother tells you that he recently ate a cookie at a family picnic. What condition is most likely to be present in this child?

A 7-year-old child in cardiac arrest is brought to the emergency department by ambulance. No palpable pulses are detected. The child’s ECG is shown here. How would you characterize this child’s rhythm?

Use this scenario to answer questions 6-7: An unresponsive 9-year-old boy was given a dose of rectal valium by his caretaker for a prolonged seizure. His blood pressure is 80/40 mm Hg, heart rate is 45/min, respiratory rate is 6/min, and SpO2 is 60% on room air. He is unresponsive and cyanotic. The cardiac monitor displays the rhythm shown here. What action do you take next?

Use this scenario to answer questions 27-28:After rectal administration of diazepam, an 8-year-old boy with a history of seizures is now unresponsive to painful stimulation. His respirations are shallow, at a rate of 10/min. His oxygen saturation is 94% on 2 L/min of nasal cannula oxygen. On examination, the child is snoring with poor chest rise and poor air entry bilaterally. If the patient continues to snore and exhibit poor chest rise and poor air entry bilaterally after your initial intervention, what action is most appropriate to take next?
