The nurse explains to the patient that blood pressure measures
The amount of pressure exerted by the veins and arteries on the heart
The amount of blood volume within the blood vessels
The amount of resistance within the veins during heart contraction
The amount of force being placed on arteries by blood
The Correct Answer is D
A. The amount of pressure exerted by the veins and arteries on the heart.: This is not accurate. Blood pressure specifically measures the force exerted by blood on the walls of arteries, not veins, and not the pressure they exert on the heart.
B. The amount of blood volume within the blood vessels.: This is incorrect. Blood pressure is related to blood volume, but it specifically measures the force against the arterial walls.
C. The amount of resistance within the veins during heart contraction.: Blood pressure refers to arterial pressure, not venous resistance.
D. The amount of force being placed on arteries by blood.: This is correct. Blood pressure measures the force of blood pushing against the walls of the arteries as the heart pumps blood through the circulatory system.

Correct Answer is C
Explanation
A. Provide names of support groups: While support groups can offer emotional and educational support, they do not address the immediate financial barrier to obtaining necessary medications.
B. Schedule an annual physical examination: Regular check-ups are important, but they do not directly address the issue of medication affordability and access to care.
C. Refer the patient to a free clinic: Free clinics often provide low-cost or no-cost medications and healthcare services, which can help the patient access the necessary treatments and follow-up care.
D. Refer the patient for financial assistance: Financial assistance programs can be helpful, but they might take time to apply and be approved. Immediate referral to a free clinic can provide more immediate support.
Correct Answer is ["A","B","E"]
Explanation
A. "It is caused by a tumor of the adrenal gland.": This statement is incorrect as a tumor of the adrenal gland (like a pheochromocytoma) would cause secondary hypertension, not primary hypertension, which has no identifiable cause.
B. "The cause can be identified with magnetic resonance imaging.": Primary hypertension does not have a specific identifiable cause, and imaging like MRI cannot pinpoint a cause for it. This statement indicates a misunderstanding.
C. "The cause is unknown.": This statement is correct for primary hypertension, as it is characterized by having no identifiable underlying cause.
D. "There are no tests to identify the cause.": This is correct for primary hypertension since it has no specific identifiable cause. The diagnosis is based on excluding other potential causes of secondary hypertension.
E. "An arteriogram will show why hypertension is occurring.": An arteriogram might identify blockages or other issues in the arteries, but it will not show the cause of primary hypertension. This indicates a need for further teaching.
