The nurse is assessing a client who recently had an upper respiratory infection and now presents to the emergency department with lower extremity numbness and difficulty swallowing. Based on these findings, this client is at greatest risk for which pathophysiological condition?

The laboratory results show a fasting 1-hour glucose screen level of 164 mg/dL and a fasting blood sugar level of 168 mg/dL from a 3-hour oral glucose tolerance test, both of which are above the normal range. Additionally, a two-hour postprandial glucose level of 220 mg/dL is also elevated. These findings suggest the possibility of gestational diabetes mellitus (GDM), a condition of glucose intolerance that arises during pregnancy.

According to the American Diabetes Association, GDM is diagnosed if two or more plasma glucose levels meet or exceed certain thresholds, which include a fasting glucose concentration of 95 mg/dL, a 1-hour glucose concentration of 180 mg/dL, and a 2-hour glucose concentration of 155 mg/dL. The patient's values surpass these thresholds, indicating that further evaluation and management for GDM may be necessary.

A. Acetaminophen 650 mg PO every 6 hours for temperature greater than 101.0° F (38.3° C): While managing fever is important, it is not as immediate a priority as ensuring the client's breathing and hydration.

B. Start a peripheral IV: Establishing a peripheral IV line is crucial for administering medications and fluids. This is essential for the client's hydration and potential intravenous medication needs.

C. Chest x-ray: Although a chest x-ray is important for diagnosing the cause of the symptoms, it can be done after the client’s immediate needs for oxygen and IV access are addressed.

D. NPO: Keeping the client NPO is necessary, but it doesn't require immediate action compared to oxygenation and IV access.

E. Start oxygen 3 L/minute via nasal cannula: The client is experiencing difficulty breathing, so providing supplemental oxygen is a priority to ensure adequate oxygenation and alleviate respiratory distress.

F. Sputum culture: Obtaining a sputum culture is important for diagnosis, but it can wait until after the client is stabilized with oxygen and IV access.

G. Place the client on a cardiorespiratory monitor: Monitoring the client's cardiac and respiratory status is important, but ensuring oxygenation and IV access takes precedence.

H. Run 0.9% sodium chloride IV infusion at 150 mL/hour: While starting the IV infusion is important, it follows the establishment of the IV line and oxygen administration.
