A nurse evaluates the following arterial blood gas values in a patient: pH 7.48, PaO 98 mm Hg, PaCO 28 mm Hg, and HCO - 22 mEq/L (22 mmol/L). Which patient condition does the nurse correlate with these results?

A. Cool the burn with ice water:

Not recommended: Cooling a burn with ice water directly is not recommended as it can lead to further tissue damage and complications. Instead, the burn should be cooled with cool (not cold) running water for a limited time and then covered with a clean, dry cloth.

B. Administer opioid analgesics:

Recommended: Severe burns can cause excruciating pain, and opioid analgesics are often necessary to manage this pain effectively. However, the specific opioid, dosage, and route of administration should be determined by the healthcare provider based on the client's condition and pain level.

C. Administer systemic antibiotics:

Not routinely recommended: Unless there are signs of infection or the burn involves deep tissue damage, systemic antibiotics are not typically administered prophylactically for burn injuries. However, if there are signs of infection, such as redness, swelling, warmth, or drainage from the burn site, antibiotic therapy may be initiated based on culture and sensitivity results.

D. Administer benzodiazepines for anxiety management:

Considered: Severe burns can cause significant psychological distress and anxiety in patients. Benzodiazepines may be considered to manage acute anxiety and agitation in these situations. However, the decision to administer benzodiazepines should be made based on the client's overall condition, vital signs, and response to non-pharmacological interventions for anxiety.

E. Lay the head of the bed flat:

Not recommended: In a client with severe burns who is experiencing increased work of breathing, anxiety, and rapid breathing, it is generally more beneficial to elevate the head of the bed slightly (semi-Fowler's position) to improve respiratory mechanics and reduce anxiety-related respiratory distress.

A. Diarrhea and vomiting for 36 hours:

Diarrhea and vomiting can lead to metabolic acidosis due to loss of bicarbonate and increased hydrogen ion concentration in the blood. However, the ABG values provided indicate respiratory alkalosis (high pH and low PaCO2), which is not consistent with metabolic acidosis caused by diarrhea and vomiting. Therefore, this choice does not correlate with the ABG values.

B. Chronic obstructive pulmonary disease (COPD):

COPD is a respiratory condition characterized by airflow limitation and increased airway resistance. It can lead to respiratory acidosis due to retention of carbon dioxide (PaCO2 levels would be elevated). The ABG values in the scenario show respiratory alkalosis (low PaCO2), which is the opposite of what would be expected in COPD. Therefore, this choice does not correlate with the ABG values provided.

C. Anxiety-induced hyperventilation:

Anxiety-induced hyperventilation is a common cause of respiratory alkalosis. During hyperventilation, there is excessive elimination of carbon dioxide (PaCO2 levels decrease), leading to an increase in pH (alkalosis). The ABG values in the scenario show a high pH (7.48) and low PaCO2 (28 mm Hg), consistent with respiratory alkalosis seen in hyperventilation due to anxiety.

D. Diabetic ketoacidosis and chronic obstructive pulmonary disease (COPD):

Diabetic ketoacidosis (DKA) is a metabolic condition characterized by hyperglycemia, ketosis, and metabolic acidosis (low pH and low bicarbonate levels). COPD, as mentioned earlier, can lead to respiratory acidosis due to retained carbon dioxide. Neither of these conditions correlates with the ABG values provided, which show respiratory alkalosis (high pH and low PaCO2). Therefore, this choice does not correlate with the ABG values.
