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 B
Explanation
A. Root cause analysis:
Root cause analysis is a method used to identify the underlying causes of adverse events or errors. While it is important for quality improvement and risk management, it does not specifically involve using research and scientific data to guide clinical decision-making in client care.
B. Evidence-based practice:
Evidence-based practice (EBP) involves integrating the best available evidence from research studies with clinical expertise and patient preferences to guide decision-making in client care. By utilizing research and scientific data, nurses can identify effective interventions and strategies to improve client outcomes.
C. Benchmarking:
Benchmarking involves comparing performance metrics or outcomes against standards or best practices. While benchmarking can inform quality improvement efforts, it does not directly involve using research and scientific data to guide clinical decision-making.
D. Standardization:
Standardization involves implementing consistent processes or protocols to improve quality and safety. While standardization is important for ensuring consistency in care delivery, it does not necessarily rely on research and scientific data to inform clinical decision-making as evidence-based practice does.
Correct Answer is D
Explanation
A. "Opioid narcotics are restricted for the client because of the risk for addiction":
This statement is not accurate and may contribute to unnecessary fear or misunderstanding about opioid use. While there is a risk of opioid addiction, it is generally low when opioids are used appropriately for pain management, especially in end-of-life care settings where the focus is on comfort and symptom management.
B. "Using opioid narcotics will limit options available for future management of pain":
This statement is misleading and may cause unnecessary concern. In end-of-life care, the priority is to provide effective pain relief and maximize comfort for the client. Opioid narcotics are an essential component of pain management in palliative and hospice care and do not necessarily limit future pain management options.
C. "The use of opioid narcotics is restricted to when death is imminent":
This statement is not accurate. Opioid narcotics can be used for pain management at various stages of illness, including but not limited to end-of-life care. While opioids are commonly used in palliative and hospice care settings, they may also be indicated for pain management in other clinical contexts.
D. "The dosage of the opioid narcotic is unlimited":
This statement is the most appropriate response. In end-of-life care, the goal of pain management is to relieve suffering and maximize comfort. Opioid dosages are titrated based on the client's pain intensity and response, and there is no strict limit to the dosage if needed to achieve adequate pain control. The priority is to ensure that the client is comfortable and free from pain as much as possible, even if higher doses of opioids are required.
