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 A
Explanation
Choice A rationale:
The provider prescribes 20 mEq of KCL. The bottle is labeled as 10 mEq/mL. Therefore, to administer 20 mEq, the nurse should give 2 mL (20 mEq ÷ 10 mEq/mL = 2 mL).
Choice B rationale:
Administering 2.5 mL would give 25 mEq of KCL, which is more than the prescribed dose.
Choice C rationale:
Administering 1.5 mL would give 15 mEq of KCL, which is less than the prescribed dose.
Choice D rationale:
Administering 1 mL would give 10 mEq of KCL, which is half the prescribed dose.
