Final answer:
The nurse should retake the temperature using a different method to ensure accuracy, because the first reading might be affected by factors such as thermometer's uncertainty or malfunction. Only after confirming an abnormal temperature should further steps be considered, including documenting or consulting a healthcare provider if necessary.
Step-by-step explanation:
The correct option : 1
The appropriate action by the nurse after obtaining an abnormally low oral temperature measurement on a child who appears well would be to retake the temperature using a different method. This is because the first measurement may be inaccurate due to various reasons such as the thermometer's uncertainty, improper positioning of the thermometer, the child's recent ingestion of cold or hot food or drink, or even device malfunction. Documenting the temperature and continuing to monitor the child would be the next step after confirming the temperature with a more reliable measurement.
Administering medication to reduce the temperature is not appropriate, as a low temperature does not demand such an intervention. Notifying the healthcare provider immediately is not necessary unless the repeated temperature reading confirms an abnormal reading or other concerning symptoms are present. An understanding of the principles related to body temperature regulation and the potential impact of thermometer uncertainty is essential in clinical practice. A thermometer with a high degree of uncertainty can lead to misinterpretation of a patient's true body temperature, necessitating a retake with a more accurate device or alternative method.
