Correct Answer is D
Explanation
Choice A rationale
Lubricating the thermometer before inserting it into the ear is not a standard practice for using a tympanic thermometer. Tympanic thermometers are designed to be used without lubrication, and using lubrication could interfere with the accuracy of the reading.
Choice B rationale
Holding the thermometer in place for a full three minutes is unnecessary for tympanic thermometers. These thermometers provide quick readings, usually within a few seconds, and holding it for longer does not improve accuracy.
Choice C rationale
Pulling the client’s auricle down and back is the correct technique for infants and young children. For adults, the correct technique is to pull the auricle up and back to straighten the ear canal for an accurate reading.
Choice D rationale
Using positive reinforcement to affirm that the procedure is being performed correctly is the appropriate action. The UAP is using the correct technique by pulling the client’s auricle up and back, which is the proper method for adults.
Correct Answer is D
Explanation
Choice A rationale
Inspecting crutches to ensure rubber tips are intact is important for safety, but it does not indicate an understanding of the proper crutch walking technique. Proper crutch walking involves using the crutches correctly to avoid injury and ensure mobility.
Choice B rationale
Practicing bicep and triceps isometric exercises can help strengthen the muscles needed for crutch walking, but it does not demonstrate an understanding of the actual crutch walking technique. The focus should be on how the crutches are used during walking.
Choice C rationale
Progressing to foot touchdown and weight-bearing of the affected leg is a part of the rehabilitation process, but it does not specifically indicate proper crutch walking technique. Proper crutch walking involves the correct use of crutches to support the body weight.
Choice D rationale
Bearing body weight on the palms of hands during the crutch gait is the correct technique for three-point gait crutch walking. This method ensures that the weight is distributed properly and reduces the risk of injury to the underarms and shoulders.
