The nurse suspects that a patient has polycythemia vera based on which finding in the patient's laboratory reports? Select all that apply.
One, some, or all responses may be correct.

Choice B rationale:

A decrease in plasma renin levels is not a known cause of primary hypertension. Primary hypertension often has no identifiable cause, and it is a diagnosis of exclusion.

Choice C rationale:

Too much plaque in the blood vessels describes atherosclerosis, which is a risk factor for hypertension but not the direct cause of primary hypertension. Plaque buildup narrows arteries and increases resistance, contributing to elevated blood pressure.

Choice D rationale:

Kidney disease can cause secondary hypertension but is not the most common cause of primary hypertension. Primary hypertension, also known as essential hypertension, is the most common form, and its exact cause remains unknown in many cases.

Choice A rationale:

Taking a daily walk is a beneficial activity for patients with venous leg ulcers. Walking promotes blood circulation, which can aid in wound healing. This statement indicates that the patient understands the importance of physical activity for their condition.

Choice B rationale:

Trying to lose weight is another positive step for a patient with venous leg ulcers, especially if the patient is overweight. Excess body weight can put additional pressure on the veins in the legs, worsening venous insufficiency. Losing weight can alleviate this pressure and improve venous circulation, supporting the healing process of leg ulcers.

Choice C rationale:

Wearing stockings after getting out of bed is a proper technique for managing venous leg ulcers. Compression stockings help improve blood flow in the legs and reduce swelling, which is beneficial for patients with venous insufficiency and leg ulcers. This statement indicates that the patient understands the importance of wearing compression stockings consistently.

Choice D rationale:

Not wearing knee-high socks that are tight around the calf is essential advice for patients with venous leg ulcers. Tight clothing, including socks or stockings, can impede blood circulation in the legs, worsening venous insufficiency and delaying wound healing. This statement indicates the need for further education because the patient should avoid any tight clothing around the affected area to promote optimal blood flow and wound healing.
