What is an integumentary manifestation of anaphylactic shock?

Cyanosis.

Urticaria.

Petechiae.

Ecchymosis.

Answer and Explanation

The Correct Answer is B

Choice A reason: Cyanosis. Cyanosis, or a bluish tint to the skin, indicates significant hypoxemia or poor oxygenation. While it can occur in severe anaphylaxis, it is not a primary integumentary manifestation.

Choice B reason: Urticaria. Urticaria, or hives, is a common integumentary manifestation of anaphylactic shock. It appears as raised, red, itchy welts on the skin due to an allergic reaction.

Choice C reason: Petechiae. Petechiae are small, pinpoint hemorrhages under the skin and are not typically associated with anaphylactic shock. They are more related to conditions involving bleeding or clotting disorders.

Choice D reason: Ecchymosis. Ecchymosis, or bruising, is not a characteristic manifestation of anaphylactic shock. It is more related to trauma or bleeding disorders.

Correct Answer is B

Explanation

Choice A reason: Respiratory acidosis. Respiratory acidosis occurs when there is inadequate ventilation, leading to increased carbon dioxide levels in the blood. Hyperventilation would not cause respiratory acidosis.

Choice B reason: Respiratory alkalosis. Hyperventilation results in excessive expulsion of carbon dioxide, leading to a decrease in carbonic acid levels in the blood. This causes respiratory alkalosis, which is expected in the early stages of hypovolemic shock as the body attempts to compensate for decreased oxygen delivery.

Choice C reason: Metabolic acidosis. Metabolic acidosis results from an accumulation of acid or loss of bicarbonate in the body. It is typically seen in the later stages of shock when lactic acid builds up due to anaerobic metabolism.

Choice D reason: Metabolic alkalosis. Metabolic alkalosis occurs due to an excessive loss of acids (e.g., through vomiting) or an accumulation of bicarbonate. Hyperventilation does not cause metabolic alkalosis.

A. Stroke volume x heart rate. B. Afterload x preload. C. Ejection fraction x blood pressure. D. Systolic x diastolic BP.

Correct Answer is A

Explanation

Choice A reason: Stroke volume x heart rate. Cardiac output is the volume of blood the heart pumps per minute, calculated by multiplying the stroke volume (the amount of blood ejected with each heartbeat) by the heart rate (the number of beats per minute).

Choice B reason: Afterload x preload. Afterload and preload are important factors influencing cardiac function but do not directly calculate cardiac output. Afterload refers to the resistance the heart must overcome to eject blood, and preload refers to the initial stretching of the heart muscle prior to contraction.

Choice C reason: Ejection fraction x blood pressure. Ejection fraction is a measure of the percentage of blood ejected from the heart with each beat, and blood pressure is the force exerted by circulating blood on the walls of blood vessels. These factors influence cardiac function but do not directly calculate cardiac output.

Choice D reason: Systolic x diastolic BP. Systolic and diastolic blood pressure are measurements of pressure during heartbeats and between beats, respectively. They are not used to calculate cardiac output.
