A client's insulin dosage is 16 units of regular insulin in the morning. The client should be taught to expect the insulin peak within:

A. While epinephrine is crucial in cases of anaphylaxis, it should not be the first action taken. The immediate priority is to stop the offending medication.
B. While assessing vital signs is important, it is not the first action. The primary concern is to halt the exposure to the potential allergen.
C. The first action in this situation should be to immediately stop the infusion of the antibiotic. This prevents further exposure to the allergen and is critical to managing the potential anaphylactic reaction.

D. While providing oxygen may be necessary later if the client is hypoxic, the immediate priority is to stop the infusion of the antibiotic first. Administering oxygen is important but comes after halting the offending agent.

A. Lethargy can occur in DKA due to the effects of hyperglycemia, acidosis, and dehydration. Even if the client is oriented, confusion about the reason for care suggests an altered mental state, which can be common in DKA.
B. This ABG indicates alkalosis (pH > 7.45), which is not typical for DKA. In DKA, we would expect a lower pH (acidosis). This set of values does not align with the expected clinical picture of DKA.
C. This ABG shows a pH of 7.31, indicating acidosis. The low HCO3 (17) supports metabolic acidosis, which is characteristic of DKA. This finding is consistent with the expected laboratory results in a patient experiencing DKA.
D. A heart rate of 52 (bradycardia) is not a common finding in DKA. In fact, tachycardia (elevated heart rate) is typically observed due to dehydration and compensatory mechanisms. Bradycardia would not be expected in this context.
E. A respiratory rate of 31, particularly if deep (known as Kussmaul respirations), is a classic sign of metabolic acidosis, including DKA. Kussmaul respirations are the body’s attempt to compensate for acidosis by increasing carbon dioxide elimination.
