Signs and symptoms of peripheral arterial disease may include which one of the following?
Strong pulses in the feet
Cyanosis of skin when feet are elevated
Skin that is warm to the touch
Excessive hair growth on the toes
The Correct Answer is B
A. Strong pulses in the feet is incorrect because peripheral arterial disease (PAD) is characterized by weak or absent pulses in the lower extremities due to arterial narrowing or obstruction, which reduces blood flow to the limbs.
B. Cyanosis of skin when feet are elevated is correct because PAD causes impaired arterial blood flow, and when the legs are elevated, less oxygen-rich blood reaches the tissues, leading to pale or bluish discoloration (cyanosis). This is often accompanied by cool skin, delayed capillary refill, and pain with exertion (claudication).
C. Skin that is warm to the touch is incorrect because the affected limbs in PAD are typically cool or cold, reflecting poor blood perfusion. Warmth would suggest adequate blood flow or inflammation, not arterial insufficiency.
D. Excessive hair growth on the toes is incorrect because PAD usually results in hair loss on the lower legs and toes, along with thin, shiny skin. Hair loss occurs because reduced blood supply limits nutrients and oxygen needed for hair growth.

Correct Answer is A
Explanation
A. Transport oxygen from the lungs to the tissues is correct because erythrocytes (red blood cells) contain hemoglobin, a protein that binds oxygen in the lungs and carries it to tissues and organs throughout the body. Hemoglobin also plays a role in transporting a small portion of carbon dioxide back to the lungs, but the primary function of erythrocytes is oxygen delivery.
B. Form blood clots to stop bleeding is incorrect because this is the function of platelets (thrombocytes), which aggregate at sites of vascular injury to initiate clot formation and prevent excessive blood loss.
C. Remove carbon dioxide from the body is incorrect because, although erythrocytes assist in transporting some carbon dioxide from tissues to the lungs, this is not their main purpose. Carbon dioxide removal is a secondary function compared with oxygen transport.
D. Produce antibodies for immune responses is incorrect because antibody production is performed by B lymphocytes (a type of white blood cell). Erythrocytes do not have immune functions and are solely involved in gas transport.
Correct Answer is D
Explanation
A. Leukopenia is incorrect because leukopenia refers to a reduction in the number of white blood cells (WBCs). This condition can occur in bone marrow suppression, viral infections, autoimmune disorders, or chemotherapy. A low WBC count indicates weakened immune defense, which is the opposite of leukocytosis.
B. Thrombocytopenia is incorrect because thrombocytopenia refers to a decrease in platelets, the blood components responsible for clotting. While low platelets can lead to bleeding complications, they are not related to white blood cell counts or immune responses.
C. Thrombocytosis is incorrect because thrombocytosis refers to an increase in platelet count, which may occur during inflammation, infection, or certain bone marrow disorders. Although platelets can play a role in the inflammatory response, thrombocytosis specifically affects clotting, not the number of white blood cells.
D. Leukocytosis is correct because leukocytosis is an increase in the total number of white blood cells in the blood. It is a common response to infection, inflammation, stress, trauma, or tissue injury. White blood cells are crucial components of the immune system that help the body identify, attack, and destroy pathogens. In clinical practice, leukocytosis is often used as a diagnostic marker for infections or inflammatory conditions, and the differential count can provide more detailed information about which type of WBC is elevated (neutrophils, lymphocytes, eosinophils, etc.), helping guide treatment decisions.
