A patient's blood pressure (BP) reading is 142/91 mm Hg. How would the nurse classify the BP?
Normal.
Prehypertension.
Hypertension, stage 1.
Hypertension, stage 2.
The Correct Answer is C
Choice A rationale:
A normal blood pressure reading is typically around 120/80 mm Hg. The given reading of 142/91 mm Hg indicates elevated blood pressure.
Choice B rationale:
Prehypertension is defined as systolic blood pressure between 120-139 mm Hg or diastolic blood pressure between 80-89 mm Hg. The diastolic reading of 91 mm Hg places this patient in the stage 1 hypertension category.
Choice D rationale:
Hypertension, stage 2, is characterized by a systolic blood pressure of 140 mm Hg or higher and a diastolic blood pressure of 90 mm Hg or higher. While the systolic reading meets the criteria, the diastolic reading of 91 mm Hg falls into the stage 1 hypertension category.

Correct Answer is C
Explanation
Choice A rationale:
Serotonin is a neurotransmitter that plays a role in mood regulation, sleep, and other functions in the body. It is not a component that forms an adhesive bridge between platelets and vascular subendothelial structures in the clotting process.
Choice B rationale:
Platelet factor III is not a component that forms an adhesive bridge between platelets and vascular subendothelial structures in the clotting process. Platelet factor III is not widely recognized in the context of clotting; it is more commonly referred to as tissue factor and is involved in the extrinsic pathway of coagulation.
Choice C rationale:
Von Willebrand factor (VWF) is a protein that plays a crucial role in hemostasis. It forms an adhesive bridge between platelets and vascular subendothelial structures, particularly at sites of vascular injury. VWF helps platelets adhere to the injured vessel wall, leading to the formation of a stable blood clot. This process is essential for preventing excessive bleeding. A deficiency or dysfunction in VWF can lead to von Willebrand disease, a bleeding disorder characterized by prolonged bleeding times.
Choice D rationale:
Adenosine diphosphate (ADP) is a molecule released by platelets when they are activated. ADP helps in the aggregation of platelets, but it does not directly form an adhesive bridge between platelets and vascular subendothelial structures.
Correct Answer is D
Explanation
Choice A rationale:
This statement is incorrect. Mexican Americans do not have higher rates of good blood pressure control compared to other populations.
Choice B rationale:
This statement is incorrect. Mexican Americans are not more likely to receive treatment for hypertension compared to other populations.
Choice C rationale:
This statement is incorrect. While hypertension is prevalent among Mexican Americans, stating they have the highest prevalence of hypertension in the world is inaccurate. The prevalence of hypertension is influenced by various factors and can vary across different regions globally.
