The nurse is taking care of a patient who is newly diagnosed with heart disease. The patient is asking questions about how blood flows through the heart.
The nurse responds, when the left ventricle contracts, it pushes blood through a valve to the:
Pulmonary artery.
Aorta.
Inferior vena cava.
Pulmonary vein.
The Correct Answer is B
Choice A rationale:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.
Choice B rationale:
The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen.
Choice C rationale:
The inferior vena cava carries deoxygenated blood from the lower half of the body back to the right atrium of the heart, not from the left ventricle.
Choice D rationale:
The pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.

Correct Answer is ["B","D","E"]
Explanation
The correct answers are B, D, and E.
Choice A Reason: The provider’s name is not an acceptable client identifier for medication administration. The provider’s name is associated with the person who prescribes or orders the medication, not the client who is to receive it. It does not reliably identify the individual for whom the service or treatment is intended.
Choice B Reason: The client’s full name is a primary and acceptable identifier. It is unique to the individual and is used to match the service or treatment to that individual. It is one of the most common identifiers used in healthcare settings to ensure that the correct patient receives the correct medication.
Choice C Reason: The facility room number is not an acceptable identifier. Room numbers can change if patients are moved, and they are not unique to an individual. Therefore, they do not reliably identify the person for whom the service or treatment is intended.
Choice D Reason: An identification number the facility assigns, such as a medical record number, is an acceptable identifier. It is unique to the client and is used across healthcare settings to track patient information, including medication administration.
Choice E Reason: The client’s telephone number can be considered an acceptable identifier, especially in settings where other identifiers might not be available. It is unique to an individual and can be used to verify the client’s identity.
