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:

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:

Bradycardia, or a slow heart rate, is not typically an early sign of circulatory overload.

Choice B rationale:

Dyspnea, or difficulty breathing, is an early sign of circulatory overload. This occurs because the heart is unable to pump the excess blood effectively, leading to fluid buildup in the lungs.

Choice C rationale:

Flushing, or reddening of the skin, is not typically an early sign of circulatory overload.

Choice D rationale:

Vomiting is not typically an early sign of circulatory overload.
