Which factors may contribute to hypertension? (Select All that Apply.)
Decreased stimulation of the sympathetic nervous system (SNS).
Decreased elasticity of blood vessels.
Increased peripheral vascular resistance (PVR).
Decreased fluid volume.
Increased blood viscosity.
Correct Answer : B,C,E
(A) Decreased stimulation of the sympathetic nervous system (SNS): The sympathetic nervous system (SNS) plays a key role in regulating blood pressure. When the SNS is stimulated, it causes vasoconstriction, or narrowing of the blood vessels, which increases blood pressure. Therefore, decreased stimulation of the SNS would typically lead to vasodilation, or widening of the blood vessels, which would lower blood pressure, not increase it.
(B) Decreased elasticity of blood vessels: As people age, their blood vessels can lose elasticity, which can lead to hypertension. When blood vessels are elastic, they can easily expand and contract with each heartbeat, maintaining a healthy blood pressure. But when they become stiff or rigid, they can’t expand as easily, causing the pressure inside to increase.
(c) Increased peripheral vascular resistance (PVR): Peripheral vascular resistance is the resistance that blood must overcome to flow through the blood vessels. The more resistance, the harder the heart has to work to pump blood through the body, which can lead to increased blood pressure. Factors that can increase PVR include vasoconstriction, or narrowing of the blood vessels, and increased blood viscosity, or thickness.
(D) Decreased fluid volume: Decreased fluid volume, or hypovolemia, would typically lead to a decrease in blood pressure, not an increase. This is because blood pressure is directly related to the volume of blood in the blood vessels. When there’s less blood, the pressure inside the blood vessels is usually lower.
(E) Increased blood viscosity: Blood viscosity refers to the thickness of the blood. When blood is thicker, it’s harder for it to flow through the blood vessels, which increases the resistance to blood flow, leading to increased blood pressure.

Correct Answer is D
Explanation
A. A critical pathway for clients who have had a stroke:
Critical pathways are structured multidisciplinary care plans that outline essential steps in the care of patients with specific conditions. While critical pathways are valuable tools for standardized care, they are not specifically focused on health promotion activities for clients with hypertension.
B. Standards of care for monitoring clients who have a history of blood pressure elevation:
Standards of care typically outline the minimum level of care that should be provided to clients based on evidence-based practice. While monitoring clients with a history of blood pressure elevation is important, it does not encompass the comprehensive health promotion activities related to hypertension.
C. Acute care facility protocols for clients experiencing an abrupt change in mental status:
Acute care facility protocols are designed to guide the management of acute changes in a patient's condition. While relevant to patient care, these protocols do not specifically address health promotion activities for clients with hypertension.
D. Clinical practice guidelines for the management of high blood pressure:
Clinical practice guidelines provide evidence-based recommendations for the management of specific health conditions. They typically include information on health promotion activities, risk factor modification, lifestyle interventions, and pharmacological management for clients with hypertension. Therefore, clinical practice guidelines are the most appropriate resource for information on health promotion activities for clients with hypertension.
Correct Answer is A
Explanation
A. Provide educational material written at an eighth-grade reading level: This is correct. Health education materials should be written at a level that is easily understandable by the majority of patients. An eighth-grade reading level is often recommended to ensure that the information is accessible to a wide range of patients.
B. Ensure privacy for the client: This is also correct. Privacy is a fundamental right of all patients and is particularly important when discussing sensitive topics such as preoperative care. Ensuring privacy can help the patient feel more comfortable and facilitate open communication.
C. Start with the least important information: This is not recommended. When providing education, it’s generally best to start with the most important information. Patients may be anxious or overwhelmed, and they may not remember everything that is discussed. By starting with the most important information, you increase the chances that the patient will remember and understand the key points.
D. Dim the lights in the client’s room: While creating a comfortable environment is important, dimming the lights is not specifically related to preoperative teaching. The focus should be on providing clear, understandable information and addressing the patient’s questions and concerns.
