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 D
Explanation
A. The superior vena cava is responsible for returning deoxygenated blood from the upper body to the heart and is not directly involved in myocardial ischemia.
B. The carotid artery supplies blood to the brain and is not the primary focus in the context of myocardial infarction.
C. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is not involved in coronary circulation.
D. The coronary arteries supply blood to the heart muscle itself. Ischemia during a myocardial infarction occurs when these arteries are blocked or narrowed, leading to a lack of blood flow and oxygen to the heart tissue.
Correct Answer is C
Explanation
A. While monitoring cardiac output can provide insights into heart function, it does not directly determine the presence of dysrhythmias.
B. Peripheral extremity circulation is influenced by cardiac output but is not the primary focus of monitoring it.
C. Cardiac output is essential for determining the heart's ability to meet the body's oxygenation requirements; low cardiac output can lead to inadequate oxygen delivery.
D. Ventilation status refers to the respiratory function and is not directly assessed through cardiac output measurements.
