A client brings their 5-year-old child to the clinic for a routine visit. The nurse needs to measure the child's height. What technique should the nurse use?

A. Correct. Having the child stand against a wall and marking their height with a pen provides an accurate measurement of height in children who are able to stand.

B. Incorrect. Instructing the child to lie down on the examination table is not the appropriate method for measuring height in a standing child.

C. Incorrect. Using a tape measure to measure the distance from head to toe is not as accurate as having the child stand against a wall for measurement.

D. Incorrect. Estimating height based on age and weight is not a reliable method for obtaining an accurate measurement.

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.
