A patient with CAD is asking the nurse about the mechanisms of the heart.
It would be appropriate for the nurse to respond that when the left ventricle contracts, it pushes blood through the semilunar valve to the:
Pulmonary vein.
Pulmonary artery.
Aorta.
Inferior vena cava.
The Correct Answer is C
Choice A rationale:
This statement is incorrect because the pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.
Choice B rationale:
This statement is incorrect because the pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.
Choice C rationale:
This statement is correct. When the left ventricle contracts, it pushes blood through the aortic semilunar valve into the aorta, the largest artery in the body.
Choice D rationale:
This statement is incorrect because the inferior vena cava carries deoxygenated blood from the lower half of the body to the right atrium, not from the left ventricle.

Correct Answer is B
Explanation
Choice A rationale:
While calling 911 is important, it is not the first action the nurse should take. The nurse should first assess the victim’s condition.
Choice B rationale:
The first action when someone is choking is to ask if they can speak. If they can speak, it means air is still passing through the windpipe.
Choice C rationale:
The jaw-thrust maneuver is used to open the airway in an unconscious victim, not in a choking victim.
Choice D rationale:
Abdominal thrusts (Heimlich maneuver) are used when the victim cannot speak, indicating a complete airway obstruction.
Correct Answer is B
Explanation
Choice A rationale:
Metabolic acidosis would likely present with rapid, deep breathing (Kussmaul respirations), not slow and shallow breathing.
Choice B rationale:
The client’s symptoms of vomiting (which can cause a loss of stomach acid), dizziness, palpitations, and numbness and tingling in the extremities and around the mouth are consistent with metabolic alkalosis.
Choice C rationale:
Respiratory alkalosis would likely present with rapid breathing, not slow and shallow breathing.
Choice D rationale:
Respiratory acidosis would likely present with rapid, shallow breathing, not slow and shallow breathing.
