A patient is admitted for pain in the arm and jaw. The patient is later diagnosed with angina.
What type of pain does the arm and jaw pain most likely represent?

Choice A rationale:

Avoiding crossing legs at the knees is a correct practice for people with PVD. It helps to prevent constriction of blood flow in the legs. When legs are crossed, pressure is applied to the veins in the lower leg, which can impede blood flow. This can lead to several problems, including:

Increased risk of blood clots Worsening of swelling in the legs Increased pain and discomfort Potential skin damage

Reinforcing this practice with the client is important.

Choice B rationale:

Not going barefoot is also a correct practice for people with PVD. It helps to protect the feet from injuries and infections. People with PVD may have reduced sensation in their feet, making them more susceptible to injuries they may not notice. Additionally, PVD can impair wound healing, so even minor injuries can become serious problems.

Reinforcing this practice with the client is important.

Choice C rationale:

Using a thermometer to check bath water temperature is not directly relevant to PVD management. While it's generally a good safety practice to avoid excessively hot water, which can burn the skin, it's not specifically related to the blood flow issues associated with PVD.

This statement indicates a need for further teaching to focus on PVD-specific self-care measures.

Choice D rationale:

Wearing stockings with elastic tops is generally recommended for people with PVD. These stockings, often referred to as compression stockings, help to improve blood flow in the legs by applying gentle pressure. This can help to reduce swelling, pain, and the risk of blood clots.

Reinforcing this practice with the client is important.

Choice A rationale:

Pallor, or paleness, is not a typical sign of phlebitis. It can be associated with other conditions such as anemia, decreased blood flow, or shock. In the context of IV therapy, pallor at the insertion site might suggest a problem with blood flow, such as infiltration or a clot, but it's not a direct indication of inflammation.

Choice B rationale:

Coolness at the IV site is also not a characteristic sign of phlebitis. It could potentially suggest infiltration of the IV fluids into the surrounding tissues, but it's not a primary indicator of inflammation. Phlebitis typically involves warmth and redness due to the inflammatory response.

Choice C rationale:

Erythema, or redness, is the hallmark sign of phlebitis. It's caused by the dilation of blood vessels in the area as part of the inflammatory response. The redness is often accompanied by warmth, swelling, and tenderness along the vein.

Mechanism of erythema in phlebitis:

When the inner lining of the vein (endothelium) is irritated or damaged by the IV catheter, it releases inflammatory mediators. These mediators cause the blood vessels to dilate, leading to increased blood flow and redness in the area.

The redness is often more pronounced along the path of the vein, rather than just at the insertion site.

Choice D rationale:

Drainage from the IV site can be a sign of infection, but it's not a primary feature of phlebitis. If drainage is present, it's important to assess for other signs of infection, such as pus, fever, or increased pain.
