A nurse is working with an interdisciplinary disaster committee to develop a community-wide emergency response plan in the event of a nonbiological or chemical incident. The nurse should include which of the following agencies to be notified immediately after calling 911?

Choice A reason: Obtain a 12-lead ECG

Obtaining a 12-lead ECG is a critical action when a client has a potassium level of 6.8 mEq/L, which indicates hyperkalemia. Hyperkalemia can cause serious cardiac dysrhythmias, including life-threatening arrhythmias such as ventricular fibrillation or asystole. An ECG can help detect these abnormalities early, allowing for prompt intervention to prevent cardiac complications. The ECG may show characteristic changes such as peaked T waves, widened QRS complexes, and prolonged PR intervals, which are indicative of hyperkalemia.

Choice B reason: Suggest that the client use a salt substitute

Suggesting that the client use a salt substitute is not appropriate in this situation. Many salt substitutes contain potassium chloride, which can further increase the potassium level in the blood. For a client with hyperkalemia, it is crucial to avoid additional sources of potassium to prevent exacerbating the condition. Therefore, recommending a salt substitute could be harmful.

Choice C reason: Advise the client to add citrus juices and bananas to her diet

Advising the client to add citrus juices and bananas to her diet is also inappropriate. Both citrus juices and bananas are high in potassium and can contribute to an increase in serum potassium levels. For a client with hyperkalemia, it is essential to limit dietary potassium intake to help lower the potassium levels in the blood. Encouraging the consumption of high-potassium foods would be counterproductive and potentially dangerous.

Choice D reason: Obtain a blood sample for a serum sodium level

While obtaining a blood sample for a serum sodium level can be part of a comprehensive assessment, it is not the immediate priority in managing hyperkalemia. The primary concern with a potassium level of 6.8 mEq/L is the risk of cardiac dysrhythmias. Therefore, obtaining an ECG to monitor the heart’s electrical activity is the most urgent and appropriate action. Once the immediate risk is addressed, further laboratory tests, including serum sodium levels, can be conducted as part of the overall assessment and management plan.

Choice A reason: Low-Grade Fever

Low-grade fever is a common early symptom of rheumatoid arthritis (RA). It is often associated with the body’s inflammatory response to the autoimmune activity occurring in the joints. While it can persist throughout the disease, it is not considered a late manifestation.

Choice B reason: Weight Loss

Weight loss can occur in RA due to chronic inflammation and its effects on metabolism and appetite. However, it is more commonly seen in the early to middle stages of the disease rather than as a late manifestation. Persistent inflammation can lead to muscle wasting and weight loss, but these are not specific to the advanced stages of RA.

Choice C reason: Anorexia

Anorexia, or loss of appetite, is another symptom that can be present in RA. It is often related to the chronic inflammation and pain associated with the disease, which can reduce a person’s desire to eat. Like weight loss, anorexia can occur at various stages of RA and is not specifically a late manifestation.

Choice D reason: Knuckle Deformity

Knuckle deformity is a late manifestation of rheumatoid arthritis. As RA progresses, the chronic inflammation can lead to joint damage and deformities, particularly in the hands and fingers. This includes changes such as ulnar deviation, swan neck deformities, and boutonnière deformities. These deformities result from the destruction of joint tissues and the formation of scar tissue, which can significantly impair hand function.
