The nurse enters a room of a patient who is acutely short of breath. Which action should the nurse take first?

D. Restlessness can be an early sign of hypoxia. Chest wall movement provides information about the effort and effectiveness of breathing, and the color of the nails can indicate cyanosis, which is a sign of poor oxygenation. These data points are directly related to assessing respiratory status and the severity of pneumonia.

A. Hiccups, sweating, and blood pressure can provide useful information about the patient's condition, they do not directly indicate the severity of respiratory distress or oxygenation status. Hiccups can be a sign of diaphragmatic irritation, sweating can indicate fever or infection, and blood pressure is a general vital sign but not specific to respiratory function.
B. Capillary refill can provide information about peripheral perfusion, and the amount of sputum can be relevant to respiratory status, particularly in an infection like pneumonia. Trembling might indicate fever or anxiety but is less directly related to respiratory status compared to other signs.
C. Pupil size and sneezing are not directly related to respiratory function in pneumonia. Pain location could be relevant if it indicates pleuritic pain, but this set of data does not provide the most critical information for assessing respiratory function and oxygenation in a patient with pneumonia.

C. Raisins are a source of carbohydrates, particularly simple sugars like glucose and fructose, which can quickly raise blood sugar levels during an episode of hypoglycemia. However, they do not contain protein, which can help sustain blood sugar levels over time. Raisins may provide a rapid increase in blood sugar but may not be as effective at preventing subsequent episodes of hypoglycemia.
A. Cheese is a source of protein and contains very little carbohydrate. While protein can help stabilize blood sugar levels, it may not provide a rapid increase in blood sugar during an episode of hypoglycemia. Cheese alone may not be the most effective choice for treating low blood sugar promptly.
B. Beef jerky is primarily a source of protein and may not contain enough carbohydrates to quickly raise blood sugar levels during an episode of hypoglycemia. While protein can help stabilize blood sugar over time, it may not provide the rapid increase in blood sugar needed to address acute hypoglycemia.
D. Chocolate, especially dark chocolate with a high cocoa content, contains carbohydrates in the form of sugar and fat. While it can quickly raise blood sugar levels due to its sugar content, it may not provide sustained energy due to its low protein content.
