A 17-year-old adolescent reports flu-like symptoms and is brought to the emergency room. What intervention should the nurse implement first?

Correct Answer: B

Rationale: The correct answer is to place a mask on the client. This intervention is crucial in preventing the spread of infections like the flu, especially in a healthcare setting where the risk of transmission is high. Assessing the client's temperature (Choice A) can be important but is not the priority in this situation. Obtaining a chest X-ray (Choice C) and determining the client's blood pressure (Choice D) are not the immediate interventions needed for a 17-year-old reporting flu-like symptoms.

Correct Answer: C

Rationale: The correct answer is C: During acute illness. Checking blood glucose during acute illness is crucial as stress can elevate glucose levels. This monitoring is essential regardless of the client's age or the type of diabetes they have. Checking before going to bed (choice A) may be important for some individuals, but it's not as universally necessary as during acute illness. Checking after meals (choice B) and prior to exercising (choice D) are important times for monitoring blood glucose, but they are not as universally applicable as during acute illness.

Correct Answer: A

Rationale: Excessive bruising and elevated blood glucose are common symptoms of Cushing's syndrome. The nurse should first check the client's blood glucose level to assess and address the hyperglycemia promptly. Administering insulin or IV fluids would be premature without knowing the current blood glucose level. Checking the skin for bruising, although important for overall assessment, does not address the immediate concern of elevated blood glucose.

Correct Answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

Correct Answer: B

Rationale: When a client with multiple sclerosis is receiving intravenous methylprednisolone, the nurse's priority action is to monitor for signs of infection. Corticosteroids like methylprednisolone can suppress the immune system, increasing the risk of infection. Monitoring for signs of infection allows for early detection and prompt intervention. Monitoring blood glucose levels may be important in clients receiving corticosteroids for prolonged periods, but it is not the priority in this case. Encouraging increased oral fluid intake is generally beneficial but not the priority over monitoring for infection. Checking the client's temperature is important but not the priority action compared to monitoring for signs of infection.
