The nurse is educating her patient on the pumping efficacy of the heart.
The nurse knows that the patient understands the teaching when the patient states:

Choice A rationale:

Increased deep tendon reflexes are not typically associated with anaphylaxis. This is more commonly seen in conditions affecting the nervous system.

Choice B rationale:

While erythema of the skin can occur in anaphylaxis, it is not the most indicative symptom of this condition.

Choice C rationale:

Bradycardia is not typically associated with anaphylaxis. Anaphylaxis is more likely to cause tachycardia, or a rapid heart rate.

Choice D rationale:

Hypotension, or low blood pressure, is a common symptom of anaphylaxis. This occurs due to widespread vasodilation in response to the allergen.

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.
