A nurse in an emergency department is caring for a child who reports being sexually abused by a family member. Which of the following actions should the nurse take?

Pyrexia, also known as fever, refers to an elevated body temperature that is above the normal range. The normal body temperature is typically around 37°C (98.6°F), and a temperature of 38.4°C (101.1°F) indicates a fever.

Alternative Choices:

1. "tachycardia" due to "heart rate of 92/min"

• Incorrect. Tachycardia refers to an abnormally high heart rate, usually above 100 beats per minute (bpm) in adults. A heart rate of 92/min is within normal limits and does not qualify as tachycardia.

2. "hypertension" due to "blood pressure of 130/78 mm Hg"

• Incorrect. Hypertension is defined as having a blood pressure reading consistently above 140/90 mm Hg. The reading of 130/78 mm Hg falls into the elevated category but does not reach the threshold for hypertension.

3. "respiratory distress" due to "respiratory rate of 18/min"

• Incorrect. A respiratory rate of 18 breaths per minute is considered normal for adults, so this finding does not indicate respiratory distress.

4. "obesity" due to "current BMI of 29.9"

• Partially correct. A BMI of 29.9 places the client in the "overweight" category, just below the threshold for obesity (BMI of 30 or higher). However, the presence of pyrexia is the more immediate clinical concern based on the provided vital signs.

Choice A rationale:

Changing the inner cannula on a tracheostomy is within the legal scope of practice for registered nurses. Nurses are trained to perform tracheostomy care, including changing the inner cannula. This procedure is within the nursing scope of practice and does not require a physician's intervention.

Choice B rationale:

Inserting a tunneled central venous catheter (such as a Hickman line) is a specialized procedure that generally falls under the scope of practice for advanced practice nurses (such as nurse practitioners or clinical nurse specialists) or physicians. RNs typically do not have the required training or authority to perform this invasive procedure.

Choice C rationale:

Irrigation of an external ear canal is within the legal scope of practice for registered nurses. Ear irrigation is a common nursing procedure used to remove impacted cerumen (earwax) and foreign bodies from the ear canal. Nurses are trained to perform this procedure safely and effectively.

Choice D rationale:

Administering blood products, including platelet transfusions, is within the legal scope of practice for an RN. RNs are responsible for preparing, verifying, and administering blood products according to institutional policies and procedures. This includes monitoring the patient during and after the transfusion for any adverse reactions.
