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

NPO status (nothing by mouth) is not a relevant intervention in this situation. It would be indicated for a patient with gastrointestinal issues or prior to a procedure, but it does not address the potential consequences of rapid fluid administration.

Restricting oral intake would not reverse or mitigate the effects of fluid overload that may have already occurred.

It's important to prioritize assessment of the patient's respiratory status, as fluid overload can lead to pulmonary edema, a serious complication.

Rationale for Choice B:

Elevating the head of the bed to high Fowler's position can be helpful in easing breathing for patients with respiratory distress, but it's not the most immediate priority in this case.

Assessing the patient's respiratory status directly through respiratory rate and lung sounds will provide more comprehensive information about potential fluid overload and guide further interventions.

Rationale for Choice C:

Measuring the client's temperature is not directly relevant to the concern of rapid fluid administration.

While fever could be a sign of infection, which might warrant fluid administration, it's not the primary concern in this scenario.

The priority is to assess for potential fluid overload, which could manifest as respiratory distress. Rationale for Choice D:

Checking the client's respiratory rate and lung sounds is the most appropriate action for the nurse to take in this situation.

Rapid infusion of 900 mL of fluid within a short period could lead to fluid overload, which can manifest as: Increased respiratory rate

Crackles in the lungs Shortness of breath Hypoxia

Early identification of these signs is crucial for prompt intervention and prevention of serious complications.
