A nurse is assessing a 10-year-old child's radial pulse. What is the appropriate technique for counting the pulse?
Use the index and middle fingers to palpate the pulse.
Use the thumb to apply pressure to the radial artery.
Apply strong pressure to detect the pulse rhythm.
Count the pulse for 10 seconds and multiply by 6.
The Correct Answer is A
A. Correct. Using the index and middle fingers to palpate the pulse provides a more accurate assessment of the radial pulse.
B. Incorrect. Using the thumb to apply pressure to the radial artery can inadvertently compress the artery, leading to an inaccurate pulse reading.
C. Incorrect. Applying strong pressure may interfere with the pulse assessment and is not necessary for detecting the pulse rhythm.
D. Incorrect. Counting the pulse for 10 seconds and multiplying by 6 is a valid method, but using the index and middle fingers for palpation is preferred for accuracy.

Correct Answer is B
Explanation
A. Incorrect. Pulling the child's earlobe down and back is a technique used for straightening the ear canal in older children and adults, not for using a tympanic thermometer.
B. Correct. When using a tympanic thermometer, it's important to gently insert the probe into the ear canal and ensure a proper seal. This helps to obtain an accurate temperature reading.
C. Incorrect. Holding the thermometer in place for 1-2 minutes is not the correct technique for tympanic temperature measurement. It may lead to an inaccurate reading.
D. Incorrect. Using an oral thermometer for a 2-year-old child is not the recommended method, as it may not provide an accurate temperature reading.
