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. Contacting the facility chaplain to visit with the client may be helpful for some clients who have spiritual needs or concerns, but it does not address the client's expressed desire to go home. The nurse should respect the client's wishes and preferences and not impose their own beliefs or values on them.
- B. Explaining the process of leaving the facility against medical advice may discourage the client from pursuing their goal of going home and imply that they are making a wrong decision. The nurse should not judge or coerce the client, but rather provide them with information and support to make an informed choice.
- C. Making a referral for social services is the best action for the nurse to take, as it will help the client access resources and services that can facilitate their discharge planning and home care arrangements. The social worker can also assist with financial, legal, or emotional issues that may arise from the terminal diagnosis.
- D. Encouraging the client to continue with inpatient care may go against the client's wishes and values, and may cause them more distress and suffering. The nurse should respect the client's autonomy and dignity and support their quality of life goals.
Correct Answer is C
Explanation
- A. Palpate the degree of edema. This is incorrect because palpating the degree of edema requires clinical judgment and skill, which are beyond the scope of practice of an AP. -
B. Regulate IV pump fluid rate. This is incorrect because regulating IV pump fluid rate is a nursing responsibility that involves calculating and adjusting the infusion rate based on the client's condition and orders.
- C. Measure the client's daily weight. This is correct because measuring the client's daily weight is a routine task that can be delegated to an AP, as long as the nurse provides clear instructions and monitors the results. The client's daily weight is an indicator of fluid balance and can help evaluate the effectiveness of treatment.
- D. Assess the client's vital signs. This is incorrect because assessing the client's vital signs requires interpretation and analysis of data, which are nursing functions that cannot be delegated to an AP.
