A nurse is preparing to administer 40 mg of furosemide IV. Available is furosemide 10 mg/mL. How many mL should the nurse administer per dose?

Choice A reason: Dependent rubor

Dependent rubor is a reddish discoloration of the skin that occurs when the leg is in a dependent position (hanging down). This condition is typically associated with arterial insufficiency rather than chronic venous insufficiency. Arterial insufficiency occurs when there is inadequate blood flow through the arteries, leading to symptoms such as pain, cramping, and changes in skin color. Dependent rubor is a sign of poor arterial circulation and is not commonly seen in venous insufficiency.

Choice B reason: Thick, deformed toenails

Thick, deformed toenails can be a sign of fungal infections or other conditions affecting the nails, but they are not specifically indicative of chronic venous insufficiency. While individuals with chronic venous insufficiency may have poor circulation that can contribute to nail problems, this symptom is not a primary or common finding associated with the condition. Instead, it is more often related to other underlying health issues.

Choice C reason: Hair loss

Hair loss on the legs can occur due to various reasons, including poor circulation. However, it is more commonly associated with arterial insufficiency rather than chronic venous insufficiency. In arterial insufficiency, the reduced blood flow can lead to hair loss, shiny skin, and other changes in the lower extremities. Chronic venous insufficiency primarily affects the veins and leads to symptoms such as swelling, varicose veins, and skin changes.

Choice D reason: Edema

Edema, or swelling, is a hallmark symptom of chronic venous insufficiency. This condition occurs when the veins in the legs are unable to effectively return blood to the heart, leading to blood pooling in the lower extremities. The increased pressure in the veins causes fluid to leak into the surrounding tissues, resulting in swelling. Edema is often more pronounced at the end of the day or after prolonged periods of standing or sitting. Managing edema is a key aspect of treating chronic venous insufficiency, and it often involves the use of compression stockings, elevation of the legs, and other measures to improve venous return.

Choice A reason: Use Wool Blankets on Your Bed

Using wool blankets is not recommended for clients on home oxygen therapy. Wool and other materials that can generate static electricity pose a fire hazard when used around oxygen. Instead, clients should use cotton or other non-static generating materials to reduce the risk of fire.

Choice B reason: Do Not Adjust the Oxygen Flow Rate

This statement indicates an understanding of the teaching. Clients should not adjust the oxygen flow rate unless instructed by their healthcare provider. The prescribed flow rate is set to meet the client’s specific needs, and any changes could lead to inadequate oxygenation or other complications.

Choice C reason: Store Unused Oxygen Tanks Horizontally

This statement is incorrect. Oxygen tanks should be stored upright and secured to prevent them from falling over. Storing tanks horizontally can increase the risk of damage and potential leaks, which can be hazardous.

Choice D reason: Check Your Oxygen Equipment Once Each Week

While it is important to regularly check oxygen equipment, doing so only once a week may not be sufficient. Clients should check their equipment daily to ensure it is functioning properly and to identify any issues that need to be addressed promptly.
