A nurse is caring for a client who suddenly develops chest pain and dyspnea. Which of the following actions should the nurse take first

A. Active movement is present: The presence of active movement in the fingers and toes of the affected arm indicates that nerve and muscle function are intact, which is a positive finding. It indicates there is no impairment in function of the affected arm.

B. Pain is 4 on scale of 0 to 10: A pain level of 4 is moderate pain and might be expected after a fracture. As long as pain is being managed appropriately with prescribed medications and no other concerning symptoms are present, it does not necessarily require immediate reporting.

C. Capillary refill is less than 2 seconds: A capillary refill time of less than 2 seconds is normal. This suggests good blood flow to the affected arm and is not an issue that needs reporting.

D. Skin is cool to the touch: A cool skin temperature on the affected arm could indicate impaired circulation, possibly due to swelling or tightness of the cast, which could lead to compartment syndrome—a serious condition that requires immediate intervention. Therefore, this finding should be reported to the provider immediately.

• request a prescription for an increase in statin medication: Although the client's total cholesterol is elevated at 230 mg/dL, adjusting lipid management is not the immediate priority during an acute chest pain episode. The immediate focus should be stabilizing airway, breathing, and circulation.
• prepare the client for cardiac catheterization: Cardiac catheterization may ultimately be needed to assess coronary artery blockages, but before this, the client must be stabilized with oxygen and medications to control chest pain and improve oxygenation.
• administer oxygen at 2 L/min via nasal cannula: The client’s oxygen saturation dropped to 92% on room air, which is low for someone experiencing chest pain and possible myocardial ischemia. Administering supplemental oxygen improves myocardial oxygen supply and reduces cardiac workload, addressing airway and breathing priorities.
• check a STAT cardiac troponin: The client’s initial troponin level was normal, but troponin can take several hours to rise after myocardial injury. While monitoring serial troponins is important, managing oxygenation and chest pain relief takes precedence right now.
• administer sublingual nitroglycerin: After ensuring oxygenation, sublingual nitroglycerin should be administered to relieve chest pain by dilating coronary arteries and decreasing myocardial oxygen demand. It helps reduce ischemia and may prevent further cardiac injury.
• request a prescription for a beta-blocker: Beta-blockers help control heart rate and blood pressure but are not the immediate first-line response for active chest pain and oxygen desaturation. Oxygen and nitroglycerin must be prioritized first to address the acute ischemic event.
