Correct Answer is A

Explanation

Choice A rationale
Serving cooked fruit with meals is an appropriate intervention for a client with a low WBC count after chemotherapy. Cooking fruit helps eliminate potential pathogens, reducing the risk of infection.
Choice B rationale
Reporting temperatures greater than 39.5°C (102.3°F) lasting more than 4 hours is not appropriate. A lower threshold for fever should be used, as even a slight increase in temperature can indicate infection in immunocompromised clients.
Choice C rationale
Placing the client in a room with negative-pressure airflow is not necessary for clients with low WBC counts. This intervention is typically used for clients with airborne infections.
Choice D rationale
Instructing the client to use an incentive spirometer every 4 hours is beneficial for lung health but does not directly address the risk of infection associated with low WBC counts.

A. Acetone breath. B. Fever. C. Serum glucose 800 mg/dL (74 to 106 mg/dL). D. Serum bicarbonate 15 mEq/L (21 to 28 mEq/L). E. Insidious onset.

Correct Answer is ["B","C","E"]

Explanation

Choice A rationale
Acetone breath is a characteristic symptom of diabetic ketoacidosis (DKA), not hyperosmolar hyperglycemic syndrome (HHS). In DKA, the body produces ketones, leading to a fruity or acetone-like breath odor. HHS, on the other hand, does not typically involve significant ketone production.
Choice B rationale
Fever can be a manifestation of HHS, often due to an underlying infection or illness that precipitates the hyperglycemic state. Infections are common triggers for HHS, leading to elevated body temperature.
Choice C rationale
Serum glucose levels of 800 mg/dL are indicative of HHS. HHS is characterized by extremely high blood glucose levels, often exceeding 600 mg/dL, without significant ketoacidosis.
Choice D rationale
Serum bicarbonate levels of 15 mEq/L are more indicative of DKA rather than HHS. In HHS, bicarbonate levels are usually within the normal range because there is no significant ketoacidosis.
Choice E rationale
Insidious onset is a hallmark of HHS. The condition develops gradually over days to weeks, unlike DKA, which has a more rapid onset.
