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 A
Explanation
- A is correct because facilitating an interdisciplinary conference at the new facility for the family can help address their concerns, provide information about the client's plan of care, and promote continuity of care.
- B is incorrect because referring the client and family to a social worker for assistance and a follow-up meeting is not enough to address their immediate concerns and does not involve other members of the health care team.
- C is incorrect because reassuring the client's family that the same provider will provide care at the new facility may not be true and does not address their specific concerns about the level of care.
- D is incorrect because telling the family that the rehabilitation facility has an excellent client care record is not enough to address their specific concerns and may sound dismissive.
Correct Answer is ["A","B","C","E"]
Explanation
Correct answer: A, B, C, E
Rationale:
- A: Alternate eating solid foods and liquids is recommended. This can help prevent dehydration and malnutrition, as well as reduce the risk of vomiting by avoiding overfilling the stomach.
- B: Eat every 2 to 3 hr is recommended. This can help maintain blood glucose levels and prevent hunger-induced nausea.
- C: Drink warm ginger ale when nauseated is recommended. Ginger has antiemetic properties and can help soothe the stomach and reduce nausea.
- E: Recommended actions is correct. The nurse should indicate which actions are recommended for the client.
- D: Increase intake of high-fat foods is contraindicated. High-fat foods can delay gastric emptying and worsen nausea and vomiting. The client should eat low-fat, bland, and easy-todigest foods instead.
