Problem 1 - Clinical Nursing Skills and Techniques

Question

The nurse is assessing the axillary temperature of a confused patient with a fever. Which actions by the nurse will best help provide an accurate measurement? (Select all that apply.) 1 Drying the axilla before placing the thermometer probe 2 Holding the thermometer probe in place 3 Placing the patient in a supine position 4 Checking that the patient has not had anything to eat or drink recently

Step-by-Step Solution

Answer

Drying the axilla and holding the thermometer in place provide an accurate measurement.

Step 1: Understanding Axillary Temperature

Axillary temperature is taken in the armpit, and it's important to ensure proper conditions for an accurate reading. This involves considering the environment in the axilla and ensuring the thermometer is used correctly.

Step 2: Drying the Axilla

Option 1 suggests drying the axilla before placing the thermometer probe. A dry environment prevents moisture from affecting the thermometer's reading, which can enhance accuracy. This action is beneficial for getting an accurate reading.

Step 3: Securing the Thermometer Probe

Option 2 suggests holding the thermometer probe in place. Ensuring the thermometer is held against the skin consistently and in the correct spot increases accuracy by preventing any shifts or incorrect placements.

Step 4: Patient's Position

Option 3 involves placing the patient in a supine position. While patient positioning can help relax the patient, it does not directly influence the accuracy of an axillary temperature reading. Hence, it might not be directly related to getting a more accurate measurement.

Step 5: Food and Drink Consumption

Option 4 is about checking if the patient has had anything to eat or drink recently. This applies more to oral temperature readings and is irrelevant to axillary measurement accuracy.

Step 6: Conclusion

Based on the options, holding the thermometer in place and drying the axilla (options 1 and 2) are actions that directly affect the accuracy of the axillary temperature reading.

Key Concepts

Axillary Temperature

Axillary temperature refers to the measurement of body heat taken at the armpit. This method is often used in settings where more invasive techniques are not suitable and is considered safe, especially for vulnerable groups like infants and confused patients. When measuring axillary temperature, it is crucial to ensure that the environment around the armpit is controlled and consistent for the most accurate reading.
To get a reliable temperature reading, the axilla (or armpit) should be free from sweat and moisture, as these can skew results. Additionally, it’s necessary to account for the ambient temperature, as it may affect the skin temperature around the axilla. It is a non-invasive method, which although generally less accurate than oral or rectal measurements, is practical and less likely to cause discomfort or distress to those being assessed.

Thermometer Probe Placement

Proper placement of the thermometer probe is vital for accurate temperature readings. For an axillary reading, the probe should be snugly tucked into the center of the armpit. This placement ensures that the probe captures the true body temperature as opposed to a reading influenced by the surrounding air.
Before placing the probe, it is a best practice to dry the axilla thoroughly. Moisture can insulate the skin, leading to a reading that might be cooler than the core body temperature. Once positioned, the probe should be held firmly in place until the device signals that the measurement is complete, preventing any shifts or displacements. It’s also crucial to ensure there is no clothing between the skin and the thermometer probe during measurement.

Patient Positioning

Patient positioning can play a role in the comfort and cooperation of the individual during temperature measurement. While positioning doesn’t directly impact axillary temperature's accuracy, it ensures that the patient remains relaxed and non-resistant, thus facilitating a proper reading.
Ideally, the patient should be seated upright or lying in a relaxed position where their arm can comfortably rest against their side. This position helps keep the thermometer probe secure and ensures consistent contact with the skin. A supine position, where the patient lies on their back, might be beneficial, particularly for patients with limited mobility, as it promotes ease of access to the armpit and stabilizes their arm.

Temperature Accuracy

Temperature accuracy in a clinical setting is critical for reliable assessment and treatment. While axillary temperatures are generally less precise than other methods like oral or rectal temperature readings, ensuring the correct technique improves their reliability.
To enhance the accuracy of an axillary temperature, you must dry the skin, properly place and secure the probe, and maintain consistent conditions throughout the measurement process. Also, ensure the probe remains in place without any movement until a reading is gathered. Avoid interference like drafts or clothing pressing against the probe which can skew results.

• Use the right type of thermometer designed for axillary temperature readings.
• Calibrate the thermometer according to the manufacturer's instructions to ensure ccurate results.

By following these guidelines, the likelihood of obtaining a correct reading is significantly enhanced, aiding in the timely and appropriate medical evaluation of the patient.
