A nurse is caring for a client with varicose veins. which clinical manifestations should the nurse expect with this diagnosis?
vova2212 [387]
The clinical manifestations should the nurse expect are reports of leg fatigue, tortuous veins in the legs and pain in lower extremities when standing.

In addition, leg fatigue is a communal clinical manifestation triggered by venous stasis and insufficient tissue oxygenation. The vein walls deteriorate and dilate causing distended, bulging veins that look tortuous and darkened. As vein walls weaken and dilate venous pressure increases and the valves turn out to be useless in which vein stasis and inadequate oxygenation end result is limb discomfort. The discolored toenails effect from a fungus below the nail or chronic hypoxia, not varicose veins, confined to a small area of heat in a calf is a mark of thrombophlebitis and reddened zones on a leg are symptomatic of thrombophlebitis.

5. body tube

Explanation:

The correct order starting from next to the object is

1. coverslip

2. objective lens

3. revolving nosepiece

4. body tube

5. body tube

A cover slip is a glass that is used to cover the specimen before observing through a microscope. Thus it is the nearest to the object.

Objective lens is the one which is near to the object hence it comes after the coverslip.

Revolving nose piece is a setup to which the objective lenses are attached thus it will come after the objective lens

Body tube is the hollow and tubular structure that forms the upper part of microscope.

While ocular lens also known as eyepiece are the farthest from the object , hence they come at the last.
