A nurse is caring for a client who has sustained a gasoline burn to 25% of the body. Which of the following is a priority safety concern when caring for this client?

A. Metabolic acidosis:

Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (<22 mEq/L) due to an excess of acids in the body or a loss of bicarbonate. However, in the given ABG values, the pH is low (7.22), but the bicarbonate level is elevated (28 mEq/L), which does not align with metabolic acidosis. Therefore, metabolic acidosis is not the correct interpretation in this case.

B. Respiratory acidosis:

Respiratory acidosis occurs when there is inadequate removal of carbon dioxide (CO2) by the lungs, leading to an accumulation of CO2 in the blood and a decrease in pH. In the ABG values provided, the pH is low (7.22), and the PaCO2 is elevated (68 mm Hg), indicating respiratory acidosis as the primary disturbance. This interpretation is supported by the elevated PaCO2 and the low pH, making it the correct choice based on the given data.

C. Respiratory alkalosis:

Respiratory alkalosis results from hyperventilation, leading to excessive elimination of CO2 and a decrease in PaCO2 levels. However, in the ABG values presented, the PaCO2 is elevated (68 mm Hg), which contradicts the expected decrease seen in respiratory alkalosis. Therefore, respiratory alkalosis is not the correct interpretation of the ABG values in this case.

D. Metabolic alkalosis:

Metabolic alkalosis is characterized by a high pH (>7.45) and a high bicarbonate level (>26 mEq/L) due to excessive loss of acids or an increase in bicarbonate levels. However, in the ABG values provided, the pH is low (7.22), and the bicarbonate level is elevated (28 mEq/L), which is not consistent with metabolic alkalosis. Therefore, metabolic alkalosis is not the correct interpretation based on the given data.

1. A. How many people live in your home?

   This question pertains to social and environmental factors but is not directly related to assessing skin inflammation on the chest. While social factors can impact overall health, such as stress levels or exposure to infectious agents, the number of people living in the client's home is unlikely to be directly related to a new skin inflammation unless there are specific circumstances, such as sharing personal care products or close contact with others who have similar skin issues.

   B. Did you have a recent exposure to irritants?

   This question is highly relevant to assessing a new skin inflammation on the chest. Exposure to irritants or allergens can trigger or worsen skin conditions, such as contact dermatitis or allergic reactions. By asking about recent exposure to potential irritants like new detergents, soaps, fabrics, chemicals, or environmental factors, the nurse can gather important information to identify possible triggers for the skin inflammation.

   C. Is nausea associated with your rash?

   Nausea is typically not directly associated with a skin rash or inflammation unless there is a systemic condition or allergic reaction causing both symptoms. While it's important to assess for any systemic signs or symptoms that may be related to the skin condition, such as fever or malaise, specifically asking about nausea may not provide relevant information about the skin inflammation on the chest.

   D. What is your body mass index?

   Body mass index (BMI) is a measure of body weight relative to height and is not directly related to assessing a new skin inflammation on the chest. While obesity or changes in body weight can sometimes contribute to skin issues, such as friction-related dermatitis or hormonal changes affecting skin health, BMI alone is not a primary assessment parameter for localized skin conditions unless there are specific concerns related to weight-related skin problems.
