A nurse is reinforcing teaching with a group of adolescents about safety. Which of the following information should the nurse include in the teaching?

Answer: B. Reposition the probe every 2 hours.

Rationale:

• A. Warm the skin prior to probe placement:While cold fingers can lead to inaccurate readings,warming the skin is not an essential step and is not routinely recommended in clinical practice.
• B. Reposition the probe every 2 hours:This iscorrect.Continuous pressure from the probe in one spot can cause skin breakdown and pressure injuries.Repositioning the probe every 2 hours helps to prevent this and ensure accurate readings.
• C. Tape the wire to the palm of the hand:This is incorrect.The pulse oximeter probe should be placed on a vascular site,such as a fingertip or earlobe.Taping the wire to the palm would not provide accurate readings.
• D. Apply the sensor to the index fingernail:This is incorrect.The fingernail does not have sufficient blood flow for accurate pulse oximetry readings.The probe should be placed on the fleshy pad of the fingertip.

Therefore, the most important action for the nurse to take is to reposition the probe every 2 hours to prevent skin breakdown and ensure accurate readings.

Additional Points:

• The nurse should also choose a clean and dry site for probe placement.
• The probe should be snug but not too tight.
• The nurse should monitor the child for signs of skin breakdown,such as redness,swelling,or pain.
• If the child is restless or active,the nurse may need to secure the probe with additional tape or a special wrap.

Choice A rationale:
Iron 100 mcg/dL The normal range for serum iron levels can vary based on age and gender, but typically, a range of 50 to 150 mcg/dL is considered normal. The provided value of 100 mcg/dL falls within this range and is not a cause for concern. Elevated iron levels can be indicative of hemochromatosis or other disorders, but this value is not concerning.
Choice B rationale:
Hemoglobin 8 g/dL Hemoglobin levels can vary by age and gender, but in general, a hemoglobin level of 8 g/dL is low and suggestive of anemia, a condition characterized by a reduced ability of the blood to carry oxygen. Anemia can lead to fatigue, weakness, and other symptoms, and the nurse should report this finding to the healthcare provider for further evaluation and management.
Choice C rationale:
Sodium 140 mEq/L The normal range for serum sodium levels is typically around 135 to 145 mEq/L. The provided value of 140 mEq/L falls within this normal range and is not a cause for concern. Deviations from this range can indicate various conditions, including dehydration or overhydration, but this value is within an acceptable range.
Choice D rationale:
Calcium 9 mg/dL The normal range for serum calcium levels can vary, but generally, a range of 8.5 to 10.5 mg/dL is considered normal. The provided value of 9 mg/dL falls within this range and is not significantly abnormal. Abnormal calcium levels can be indicative of various conditions, including thyroid disorders or kidney problems, but this value is not concerning.
