Question

The nurse is caring for a client with type 2 diabetes who has a current blood glucose of 155 mg/dL and the following vitals: Temperature 100.9 degrees F, blood pressure 142/88 mmHg, heart rate of 90, and respirations of 20 bpm. Which finding is of most concern?

Answers

  1. Temperature
    • Rationale:

      This answer is correct because the client has a fever. A fever is an indication of an infection. Infections raise blood sugar levels. The client already has an elevated blood sugar level. It is important to treat the underlying infection to maintain the client’s blood glucose levels.

  2. Blood pressure
    • Rationale:

      This answer is not correct because although blood pressure is elevated, it is not the primary concern. If the infection is not addressed, the blood glucose can raise further and cause complications.

  3. Heart rate
    • Rationale:

      This answer is not correct because the heart rate is within normal range. The primary concern is the client’s fever.

  4. Respirations
    • Rationale:

      This answer is not correct because the respirations are normal. The primary concern is the client’s fever.

Overview

An elevated body temperature indicates infection. An infection in the body needs to be addressed because it raises blood glucose and can lead to diabetic ketoacidosis.

Explanation

Learning Outcomes

An elevated body temperature indicates infection. It is important to treat the underlying infection to maintain the client’s blood glucose levels. An infection in the body needs to be addressed because it raises blood glucose and can lead to diabetic ketoacidosis. The client already has an elevated blood sugar level. Infection causes a stress response and increases cortisol and adrenaline. These hormones inadvertently raise blood sugar levels by working against insulin.

Test Taking Tip

Practice the process of elimination and critically think about the client’s status: Temperature and blood pressure are abnormal. Which values can most adversely affect the diabetic client?
