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.
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. Incorrect. The nurse should educate the parent on the importance of nebulizer treatments to deliver medications that thin and loosen mucus in the airways.
- B. Incorrect. The nurse should advise the parent to contact the provider if the child has a fever, which could indicate an infection or inflammation in the lungs.
- C. Correct. The nurse should initiate a request for a high-frequency chest compression vest, which is a device that vibrates the chest wall and helps mobilize mucus from the lungs.
- D. Incorrect. The nurse should encourage the parent to support the child's participation in team sports, which can improve lung function and social skills.
Correct Answer is D
Explanation
- A is incorrect because IV tubing for total parenteral nutrition should be changed every 24 hours to prevent infection.
- B is incorrect because abdominal distention is not an expected effect of total parenteral nutrition. It could indicate a complication such as fluid overload or bowel obstruction.
- C is incorrect because gastric residual is not relevant for total parenteral nutrition, which bypasses the gastrointestinal tract.
- D is correct because weight measurement is an important indicator of fluid balance and nutritional status for clients receiving total parenteral nutrition.
