A 4-year-old boy with a tracheostomy tube is experiencing respiratory distress. He has intercostal retractions, a heart rate of 80 beats/min, and an oxygen saturation of 85%. During his attempts to breathe, a gurgling sound is heard in the tracheostomy tube. You should:

Correct Answer: D

Rationale: In this scenario, the 4-year-old boy with a tracheostomy tube is showing signs of respiratory distress, including intercostal retractions, a low heart rate, and decreased oxygen saturation. The gurgling sound indicates a possible airway obstruction. Correctly, the immediate action should be to carefully suction the tracheostomy tube. Suctioning can help clear any secretions or obstructions, thus improving the child's ability to breathe effectively. Ventilating through the tube, placing an oxygen mask over it, or removing and cleaning the tube would not address the potential obstruction and could worsen the respiratory distress.

Correct Answer: C

Rationale: Nausea and vomiting are more common in children than adults following an isolated head injury. Children often present with gastrointestinal symptoms like nausea and vomiting after a head injury due to differences in physiological responses compared to adults.

Correct Answer: C

Rationale: Gastric distention in infants and children can lead to a decrease in ventilatory volume. This occurs because the distended stomach can limit the movement of the diaphragm, reducing its ability to contract and expand the chest cavity effectively. As a result, the amount of air entering and leaving the lungs is decreased, impacting ventilation. Tracheal rupture, acute rupture of the diaphragm, and less effective chest compressions are not typically associated with gastric distention.

Correct Answer: C

Rationale: In a pediatric patient with respiratory distress, a non-rebreathing mask with a flow rate set at 6 to 8 L/min is the most effective way to deliver oxygen. This method ensures a high concentration of oxygen is delivered to the child, aiding in improving oxygen saturation levels. In this scenario, the mother can assist in holding the mask to maintain comfort and cooperation in the child while ensuring proper oxygen delivery.

Correct Answer: D

Rationale: The symptoms of swollen ankles, tight rings, and elevated blood pressure in a pregnant woman at 22 weeks gestation are concerning for preeclampsia. Preeclampsia is characterized by high blood pressure and signs of organ damage, commonly seen with symptoms such as swelling (edema) and protein in the urine. It is crucial to monitor and manage preeclampsia promptly as it can lead to severe complications for both the mother and the baby.

Correct Answer: A

Rationale: In this scenario, the mother is showing signs of postpartum hemorrhage with increased heart rate, diaphoresis, and mild vaginal bleeding. The correct approach involves treating for shock by addressing hypovolemia and providing uterine massage to help control bleeding. Administering high-flow oxygen is essential. Therefore, the most appropriate option is to treat for shock and perform uterine massage during transport to manage the postpartum hemorrhage effectively.

Correct Answer: D

Rationale: The appropriate ventilation rate for an infant with an advanced airway is 8 to 10 breaths per minute.

Correct Answer: D

Rationale: In two-rescuer child CPR, the correct compression depth is one third the diameter of the chest. This depth can be achieved by compressing the chest with one or two hands. It is crucial to follow the correct compression depth guideline to ensure effective chest compressions and circulation during CPR for a child.

Correct Answer: B

Rationale: The occiput, the back part of the head, is proportionately larger in children compared to adults, which can have implications for airway management techniques. This anatomical difference is important to consider when providing care to pediatric patients, especially during airway interventions.
