A nurse in the emergency department is assessing an older adult client who has community-acquired pneumonia. Which of the following findings should the nurse expect?

A. The client is likely experiencing an allergic reaction to penicillin, such as anaphylaxis, which can cause symptoms like itching, dizziness, and difficulty breathing. The first step is to stop the infusion immediately to prevent further exposure to the allergen.
B. Elevating the head of the bed might be helpful if the client is experiencing respiratory distress, but stopping the infusion is the priority action.
C. Auscultating the client's breath sounds may be useful later to assess the severity of respiratory distress, but it is not the first action in an acute allergic reaction.
D. Calling the provider is important, but the immediate priority is stopping the infusion to prevent further harm from the allergic reaction.

A. Obtain a prescription for supplemental oxygen: This is the correct answer. The patient is experiencing hypoxia, and ensuring adequate oxygenation is the priority. Oxygen supplementation is essential to correct the hypoxia, which can exacerbate metabolic disturbances like diabetic ketoacidosis (DKA). Improving oxygenation will also support other treatments, such as insulin administration, by improving tissue perfusion.
B. Obtain a prescription to administer insulin: While insulin is a key treatment for DKA, addressing hypoxia first is more urgent. Hypoxia can impair the effectiveness of insulin and other therapies, so stabilizing the patient’s oxygen levels should be prioritized before insulin administration.
C. Obtain a prescription to administer intravenous fluids: Administering fluids is important in DKA management, especially for rehydration and correcting electrolyte imbalances. However, addressing hypoxia first is the priority to stabilize the patient and ensure optimal perfusion for further interventions like fluid resuscitation.
D. Obtain a prescription to check the client's glucose level: This is not necessary, as the glucose level is likely already elevated, which is characteristic of DKA. The focus should be on stabilizing the patient's airway and oxygenation before monitoring glucose levels or starting insulin.
