A school nurse is using the Weber's test to check a child's hearing acuity.
Which of the following actions should the nurse take?

Measure the amount of time the child can hear the sound.

Obtain a tympanogram reading prior to initiating the test.

Place a vibrating tuning fork on the top of the child's head.

Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Measuring the amount of time the child can hear the sound is not the correct action when performing Weber's test. Weber's test is used to assess hearing acuity and lateralization. In this test, a vibrating tuning fork is placed in the middle of the patient's forehead, and the patient is asked if the sound is heard equally in both ears or if it is louder in one ear. This helps identify whether there is a conductive or sensorineural hearing loss. The duration of hearing the sound is not relevant to this test.

Choice B rationale:

Obtaining a tympanogram reading is not necessary before initiating Weber's test. Tympanometry assesses the movement of the eardrum in response to changes in air pressure and can help diagnose conditions like middle ear effusion or eustachian tube dysfunction. However, Weber's test focuses on lateralization of sound and does not require tympanogram readings.

Choice C rationale:

Placing a vibrating tuning fork on the top of the child's head is the correct action for performing Weber's test. By doing so, the nurse can assess whether the sound is perceived equally in both ears or if it is lateralized to one ear. If the sound is lateralized, it can provide valuable information about the type of hearing loss the child may have, whether it's conductive or sensorineural.

Choice D rationale:

Holding a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears is not the correct technique for Weber's test. Placing the tuning fork directly on the patient's forehead is essential for accurate assessment. Holding it close to the ears can lead to misinterpretation of the test results.

Correct Answer is C

Explanation

- A. The LPN and AP lower the side rails before lifting the client up in bed is incorrect. This is a safe practice that prevents injury to the client and staff by providing more space for movement and reducing the risk of falling.

- B. Prior to lifting the client, the LPN and AP raise the bed to waist level is incorrect. This is a safe practice that prevents injury to the client and staff by reducing the need for bending and lifting.

- C. The LPN and the AP grasp the client under his arms to lift him up in bed is correct. This is an unsafe practice that can cause injury to the client's shoulders, neck, and axillae by applying excessive pressure and friction. The LPN and AP should use a draw sheet or a mechanical lift device to move the client up in bed.

- D. The LPN and the AP ask the client to flex his knees and push his heels into the bed as they lift is incorrect. This is a safe practice that encourages active participation from the client and reduces the workload for the staff by using leverage.

A. Adjust the crutches for comfort as needed. B. Use a three-point gait. C. Wear leather-soled shoes. D. Advance the affected leg first when walking upstairs.

Correct Answer is B

Explanation

- A. Adjust the crutches for comfort as needed. This is incorrect because the crutches should be adjusted to fit the client's height and arm length, and should not be changed without proper guidance.

- B. Use a three-point gait. This is correct because this gait allows the client to avoid putting weight on the affected leg and maintain balance and stability.

- C. Wear leather-soled shoes. This is incorrect because leather-soled shoes can be slippery and increase the risk of falls and injuries.

- D. Advance the affected leg first when walking upstairs. This is incorrect because the client should advance the unaffected leg first when walking upstairs, and the affected leg first when walking downstairs.
