Correct Answer: D

Rationale: A sudden onset of respiratory distress in a child without fever is most likely due to a foreign body airway obstruction. This obstruction can rapidly lead to difficulty breathing, stridor, and other signs of respiratory distress without necessarily causing a fever. Prompt recognition and intervention are crucial in such cases to prevent further complications and ensure the child's airway remains clear.

Correct Answer: D

Rationale: The presence of a large contusion over the left upper quadrant of the abdomen, along with signs of shock, points towards a likely injury to the spleen, especially following trauma. The spleen is located in the left upper quadrant of the abdomen and is susceptible to injury due to its position and vulnerability to blunt trauma.

Correct Answer: C

Rationale: Placing sterile dressings into the vagina is not an appropriate treatment for severe vaginal bleeding. The correct approach involves applying pressure to the external vaginal area to control bleeding, covering the vagina with a trauma dressing to help with compression, administering high concentrations of oxygen to support oxygenation, and keeping the patient warm with blankets to prevent hypothermia. Placing sterile dressings into the vagina can introduce foreign material, increase the risk of infection, and obstruct proper wound management, making it an incorrect treatment option in this scenario.

Correct Answer: C

Rationale: The ideal time to clamp and cut the umbilical cord is when it has stopped pulsating. This allows for the transfer of remaining blood from the placenta to the newborn, which can be beneficial for the baby's health and iron stores. Clamping the cord too early can deprive the newborn of this essential blood volume. Waiting for the pulsations to cease ensures that the baby receives the maximum benefits from delayed cord clamping.
