A nurse is caring for a client who has diabetes mellitus and cool, clammy skin. The client begins having a seizure. Which of the following treatments should the nurse administer?

Anticipated:

• Metoprolol 5 mg every 2 to 3 min up to three doses
• Oxygen at 2 L/min via nasal cannula
• Draw electrolytes along with Hgb and Hct
• Morphine 6 mg IV bolus every 3 hr as needed for pain
• Nitroglycerin 0.4 mg SL now may repeat every 5 min up to 3 doses

Nonessential:

• Obtain daily weight

Contraindicated:

• Atropine 0.5 mg IV bolus every 5 min up to 2 mg

Rationale:

• Metoprolol 5 mg every 2 to 3 min up to three doses: Beta-blockers reduce myocardial oxygen demand by decreasing heart rate and blood pressure, making them beneficial in acute coronary syndrome. They should be used cautiously in patients with signs of heart failure or bradycardia.
• Oxygen at 2 L/min via nasal cannula: Supplemental oxygen is recommended for clients with acute coronary syndrome when oxygen saturation is below 94% to optimize myocardial oxygen supply and prevent ischemia.
• Draw electrolytes along with Hgb and Hct: Electrolytes are critical in evaluating myocardial function, and hemoglobin/hematocrit levels help assess perfusion and oxygen-carrying capacity.
• Morphine 6 mg IV bolus every 3 hr as needed for pain: Morphine is used to relieve severe chest pain in myocardial infarction and reduce myocardial oxygen demand by decreasing anxiety and preload.
• Nitroglycerin 0.4 mg SL now may repeat every 5 min up to 3 doses: Nitroglycerin dilates coronary arteries, improving oxygen delivery to the myocardium, and reduces preload and afterload, alleviating chest pain. It is a first-line treatment for angina and myocardial infarction but should be avoided in cases of hypotension.
• Obtain daily weight: Daily weight monitoring is primarily used for fluid balance assessment in conditions like heart failure rather than for acute myocardial infarction management.
• Atropine 0.5 mg IV bolus every 5 min up to 2 mg: Atropine is used to treat bradycardia. However, the client is tachycardic, so atropine would worsen the condition and is contraindicated.

• Infection: Poor glycemic control, indicated by an elevated hemoglobin A1c of 9.5%, leads to impaired immune function, delayed wound healing, and increased risk of postoperative infections. Chronic hyperglycemia promotes bacterial growth, reduces leukocyte function, and compromises vascular integrity, further predisposing the client to infections.
• Deep vein thrombosis (DVT): Postoperative immobility, increased coagulation, and endothelial injury increase DVT risk. However, BUN of 15 mg/dL is within the normal range and does not indicate dehydration or hemoconcentration, which would contribute to thrombus formation.
• Hypovolemia: Reduced blood volume typically presents with signs such as hypotension, tachycardia, and elevated BUN/creatinine ratio. Preoperative hypertension does not indicate hypovolemia and is more commonly associated with chronic vascular resistance rather than acute fluid loss.
• BUN of 15 mg/dL: A BUN level within the normal range does not suggest an increased risk for DVT or fluid imbalance. It primarily reflects renal function and hydration status, neither of which are significantly altered in this case.
• Preoperative hypertension: While chronic hypertension is a cardiovascular risk factor, it does not indicate hypovolemia, which would present with dehydration-related signs such as orthostatic hypotension, tachycardia, and decreased urine output.
• Hemoglobin A1c: A value of 9.5% indicates poor long-term glycemic control, which impairs immune function and slows wound healing. Elevated glucose levels reduce neutrophil function, impair macrophage activity, and increase oxidative stress, all of which contribute to a heightened infection risk.
