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 A

Explanation

- A. Pink, frothy sputum is a characteristic finding of pulmonary edema, which is caused by fluid accumulation in the alveoli and interstitial spaces of the lungs. This impairs gas exchange and leads to hypoxia and respiratory distress.

- B. Bradycardia is not expected in pulmonary edema. The client is more likely to have tachycardia due to increased sympathetic stimulation and decreased cardiac output.

- C. Flushed, dry skin is not expected in pulmonary edema. The client is more likely to have pale, cool, and clammy skin due to peripheral vasoconstriction and decreased perfusion.

- D. Wheezing is not a specific finding of pulmonary edema. It may indicate bronchospasm or asthma, which are different conditions that affect the airways rather than the alveoli.

A. The client reports a decrease in episodes of nausea. B. The client reports a decrease in breast tenderness. C. The client reports a decrease in headaches. D. The client reports a decrease in urinary frequency.

Correct Answer is A

Explanation

A is correct because ginger tea is an herbal remedy that has been shown to reduce nausea and vomiting in pregnancy.

B is incorrect because ginger tea does not have any effect on breast tenderness, which is a common symptom of pregnancy caused by hormonal changes.

C is incorrect because ginger tea does not have any effect on headaches, which can be caused by various factors such as dehydration, stress, or caffeine withdrawal in pregnancy.

D is incorrect because ginger tea does not have any effect on urinary frequency, which is a common symptom of pregnancy caused by increased blood volume and pressure on the bladder.
