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 A
Explanation
A. The P wave represents atrial depolarization, which is initiated by the SA node, the heart's natural pacemaker.
B. The AV node is responsible for conducting impulses from the atria to the ventricles but does not initiate the P wave.
C. The Bundle of His transmits the electrical impulses to the ventricles but is not directly associated with the P wave.
D. Purkinje fibers are involved in ventricular depolarization, which corresponds to the QRS complex, not the P wave.
Correct Answer is B
Explanation
A. A Yankauer suction tip catheter is used for suctioning secretions and does not assess cardiac function or afterload.
B. A blood pressure cuff is essential for measuring blood pressure, which can indicate increased afterload through elevated systemic vascular resistance.
C. An oxygen cannula is used for delivering supplemental oxygen and does not provide information about cardiac afterload.
D. A pulse oximeter measures oxygen saturation, which is not directly related to assessing cardiac afterload.
