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:

Cellular hypoxia occurs when cells do not receive enough oxygen to meet their metabolic demands. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the tissues. A hemoglobin level of 10.8 g/dL is below the normal range for adults (14-18 g/dL), indicating that the client has anemia. Anemia reduces the oxygen-carrying capacity of the blood, which can lead to cellular hypoxia.

Here is a detailed explanation of how anemia can lead to cellular hypoxia:

Decreased oxygen-carrying capacity: Anemia results in fewer red blood cells or reduced hemoglobin levels within those cells. As a consequence, the blood's ability to transport oxygen to the tissues is diminished.

Impaired oxygen delivery: Oxygen is transported to the tissues through the bloodstream, attached to hemoglobin within red blood cells. With fewer red blood cells or reduced hemoglobin, the delivery of oxygen to the tissues is compromised.

Decreased oxygen availability at the cellular level: As oxygen delivery is impaired, less oxygen is available to the cells for metabolic processes. This insufficient oxygen supply leads to cellular hypoxia.

Impaired cellular function: Cells require oxygen to produce energy through a process called aerobic respiration. Cellular hypoxia disrupts this process, leading to impaired cellular function.

Tissue and organ dysfunction: When a significant number of cells within a tissue or organ experience hypoxia, the function of that tissue or organ can be compromised. This can manifest in various symptoms and complications, depending on the affected organs.

Common signs and symptoms of cellular hypoxia:

Fatigue Weakness

Shortness of breath Pale skin

Dizziness Headache Chest pain

Tachycardia (rapid heart rate) Cognitive impairment

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.
