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 D
Explanation
Choice A rationale:
Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.
Choice B rationale:
Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.
Choice C rationale:
Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.
Choice D rationale:
Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.
Correct Answer is D
Explanation
- A. Instructing the client about the importance of regular medical appointments is important, but not the priority. The nurse should first ensure that the client knows how to manage their blood glucose levels and administer insulin at home.
- B. Encouraging the client to participate in daily exercise is beneficial, but not the priority. The nurse should first ensure that the client knows how to monitor their blood glucose levels and adjust their insulin dose accordingly.
- C. Explaining proper foot care techniques to the client is essential, but not the priority. The nurse should first ensure that the client knows how to prevent and treat hypoglycemia and hyperglycemia, which can have serious complications.
- D. Ensuring that the client understands the medication regimen is the priority. The nurse should teach the client about the types, actions, doses, and administration times of insulin, as well as how to store and dispose of it safely.
