Correct Answer: D

Rationale: The correct answer is 'The infant received mechanical ventilation for 2 weeks.' Bronchopulmonary dysplasia is a condition primarily caused by therapies like positive-pressure ventilation used in the treatment of lung disease. This leads to lung damage and subsequent respiratory problems. Choices A, B, and C are not consistent with the diagnosis of bronchopulmonary dysplasia. Gestational age assessment suggesting growth retardation is more indicative of intrauterine growth restriction, clearing meconium from the airway at delivery is related to potential respiratory issues at birth, and phototherapy for Rh incompatibility is unrelated to bronchopulmonary dysplasia.

Correct Answer: B

Rationale: A red and edematous colostomy stoma is a common finding immediately after surgery, and these changes are expected to decrease over time. As the stoma heals, it usually becomes pink without signs of abnormal drainage, swelling, or skin breakdown. Therefore, the appropriate action for the nurse is to document these normal findings. Elevating the buttocks, applying ice, or calling the primary health care provider are unnecessary interventions at this stage.

Correct Answer: C

Rationale: When a toddler is choking on a piece of food and appears blue, it indicates airway obstruction. The appropriate initial action should be to perform 5 abdominal thrusts. This technique can help dislodge the obstructing object and clear the airway. Initiating mouth-to-mouth resuscitation is not recommended as the first step in a choking emergency, especially in children. Giving water may not be effective and can worsen the situation by causing further blockage. Calling the emergency response team should be considered if the abdominal thrusts are unsuccessful in clearing the airway.

Correct Answer: A

Rationale: The correct answer is chronic vessel plaque formation. Kawasaki Disease affects small and medium-sized blood vessels, leading to progressive inflammation and potential damage to the walls of medium-sized muscular arteries, which can result in coronary artery aneurysms. While other complications such as pulmonary embolism and occlusions at vessel bifurcations can occur in different conditions, for Kawasaki Disease, the primary concern is the development of chronic vessel plaque formation.

Correct Answer: A

Rationale: The correct answer is 'Loss of consciousness.' While parents should report any concerning observations, they need to call the healthcare provider immediately if the infant experiences a loss of consciousness. This change in alertness may indicate anoxia, which can be life-threatening. Tetralogy of Fallot is a congenital heart defect characterized by four main features: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Surgery for Tetralogy of Fallot may be delayed or done in stages. Reporting loss of consciousness is crucial due to the potential seriousness of the condition. Feeding problems, poor weight gain, and fatigue with crying are important issues but do not require immediate reporting like loss of consciousness does.
