A nurse preparing to start a blood transfusion will use which type of tubing?
An air vent to let bubbles into the blood
One with a filter to ensure that clots do not enter the patient
An injection port to mix additional electrolytes into the blood
Two-way valves to allow the patient's blood to mix and warm the blood transfusing
The Correct Answer is B
A. An air vent allowing bubbles into the blood would be unsafe and can cause air embolism, so this option is incorrect.
B. Using tubing with a filter is standard practice for blood transfusions to prevent clots and debris from entering the patient’s bloodstream, making this the correct choice.
C. Mixing additional electrolytes into the blood is not a standard practice during transfusions, as it can cause complications; thus, this option is not appropriate.
D. Two-way valves are not typically used in blood transfusion setups; the goal is to keep the blood product separate from other fluids unless specifically indicated.

Correct Answer is B
Explanation
A. While anxiety may contribute to hyperventilation, in the context of a febrile child, the primary factor is usually metabolic.
B. Increased metabolic demands due to fever can elevate the body’s oxygen requirements, prompting hyperventilation as a compensatory mechanism.
C. Decreased drive to breathe would not lead to hyperventilation; rather, it might result in hypoventilation or respiratory distress.
D. Infection destroying lung tissues would typically lead to respiratory distress or failure, not directly cause hyperventilation without the context of increased metabolic needs.
