Which of the following clump and adhere to the wall of the injured blood vessel to begin the process of hemostasis?

A.

White blood cells

B.

Antibodies

C.

Red blood cells

D.

Platelets

Answer and Explanation

The Correct Answer is D

White Blood Cells (WBCs): WBCs are part of the immune system and play a role in fighting infections. However, they are not directly involved in hemostasis or clot formation.

Antibodies: Antibodies are proteins produced by the immune system to recognize and neutralize foreign substances (antigens). They do not directly participate in clot formation.

Red Blood Cells (RBCs): RBCs carry oxygen and carbon dioxide but are not directly involved in clotting. They do not adhere to the vessel wall during hemostasis.

Platelets: Platelets are small cell fragments in the blood. They clump together (aggregate) at the site of injury to form a temporary plug (platelet plug). Platelets adhere to the injured vessel wall and release chemicals that initiate clotting.

Correct Answer is D

Explanation

A. Temperature of 100.8 Degrees Fahrenheit (38.2 Degrees Celsius): Fever can indicate a potential adverse reaction to the medication or may be a sign of infection, which could complicate the patient's condition. While a fever can be a sign of an infection, it's not a typical adverse effect for alteplase

B. Skin rash with urticaria: Skin rash and urticaria (hives) can indicate an allergic reaction to alteplase. Allergic reactions can range from mild to severe and may necessitate discontinuation of the medication and administration of appropriate treatment, such as antihistamines or corticosteroids, depending on the severity of the reaction but it's less common than bleeding.

C. Wheezing with labored breathing: Wheezing and labored breathing can indicate a severe allergic reaction or anaphylaxis to alteplase but again, bleeding is a more prominent concern.

D. Bruising and epistaxis: Alteplase increases the risk of bleeding due to its thrombolytic activity. Bruising and epistaxis (nosebleeds) are common manifestations of bleeding associated with alteplase therapy. Monitoring for these signs helps detect potential bleeding complications early, allowing for prompt intervention to minimize further bleeding and manage the patient's condition appropriately.

Correct Answer is {"dropdown-group-1":"A"}

Explanation

A. Whole: Complementary and alternative medicine (CAM) emphasizes treating the entire person, considering physical, mental, emotional, and spiritual aspects of health. It aims to restore balance and promote overall well-being.

B. Diseased: CAM focuses on addressing the root cause of illness, not just treating the symptoms of a disease. While disease management can be a part of CAM, it's not the sole focus.

C. Partial: CAM doesn't focus on treating only a part of the person. It aims for a comprehensive approach.

D. Impaired: While CAM can be used to address impairments, it has a broader scope that encompasses promoting overall health and preventing illness, not just treating existing limitations
