A 17-year-old patient, dying of heart failure, wants to have organs removed for transplantation after death. Which action by the nurse is correct?
Notify the health care provider about the patient's desire to donate organs.
Contact the United Network for Organ Sharing after talking with the patient.
Instruct the patient to talk with parents about the desire to donate organs.
Prepare the organ donation form for the patient to sign while still oriented.
The Correct Answer is C
A. Notifying the health care provider is not the most appropriate first action, as parental consent is needed.
B. Contacting the United Network for Organ Sharing is premature without consent from the parents.
C. Since the patient is a minor, parental consent is generally required for organ donation. Instructing the patient to discuss this desire with their parents is essential for obtaining legal consent.
D. Preparing the organ donation form is also premature, as minors cannot legally consent without parental approval.

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.
