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

White blood cells

Antibodies

Red blood cells

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 C

Explanation

A. Nausea and vomiting: Nausea and vomiting can occur with epoetin alfa, but it's not the most common side effect.

B. Orthostatic hypotension: This is not a common side effect of epoetin alfa. Orthostatic hypotension is a decrease in blood pressure upon standing.

C. Hypertension: Epoetin alfa stimulates the production of red blood cells. When the red blood cell count increases too quickly, it can lead to increased blood pressure, which is the most common adverse effect.

D. Dizziness: Dizziness can occur with epoetin alfa, but it's less common than hypertension.

A. Most CAM therapies are totally ineffective B. Additional treatment may not be needed C. Patients must be warned that most CAM therapies are dangerous D. CAM therapies could interact with prescription and OTC medications

Correct Answer is D

Explanation

A. Most CAM therapies are totally ineffective: Incorrect. Dismissing all CAM therapies as ineffective without considering individual cases could lead to overlooking potentially helpful treatments for patients.

B. Additional treatment may not be needed: Incorrect. Collecting information about CAM use allows healthcare providers to assess the overall treatment regimen comprehensively.

C. Patients must be warned that most CAM therapies are dangerous: Incorrect. While some CAM therapies may carry risks, it's not accurate to generalize that most CAM therapies are dangerous.

D. CAM therapies could interact with prescription and OTC medications: Correct. Understanding potential interactions between CAM therapies and conventional medications is essential for patient safety and optimal treatment outcomes.
