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
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.

To determine how many tablets of digoxin 0.125 mg are needed to administer a total dose of 0.25 mg, divide the desired dose by the dose per tablet:
0.25 mg (desired dose) ÷ 0.125 mg (dose per tablet) = 2 tablets
Therefore, the nurse should administer 2 tablets of digoxin 0.125 mg to the client to achieve a total dose of 0.25 mg.
Correct Answer is C
Explanation
A. Hypothermia: Clopidogrel is not typically associated with temperature regulation and wouldn't cause hypothermia.
B. Hypotension: While some medications can cause low blood pressure (hypotension), clopidogrel is not a common culprit.
C. Black stools: This can be a sign of upper gastrointestinal bleeding, which is a potential side effect of clopidogrel. Clopidogrel inhibits platelet aggregation, which can increase bleeding risk.
D. Constipation: Constipation is not a common side effect of clopidogrel.
