A patient is diagnosed with left ear unilateral sensorineural hearing loss. During the performance of the Weber test, the nurse expects lateralization of the sound/vibration to the:

Left temporal bone

Both ears equally

Right ear

Left ear

Answer and Explanation

The Correct Answer is C

Choice a reason:
The left temporal bone would be the expected site of lateralization for sound in a Weber test if the patient had conductive hearing loss in the left ear. However, with unilateral sensorineural hearing loss, the sound typically lateralizes to the opposite ear, which is the ear with better hearing.
Choice b reason:
Lateralization to both ears equally during the Weber test would suggest either normal hearing or symmetrical hearing loss. In the case of unilateral sensorineural hearing loss, the sound is not perceived as equal in both ears because the affected ear does not hear as well as the unaffected ear.
Choice c reason:
In a patient with unilateral sensorineural hearing loss in the left ear, the Weber test will lateralize to the right ear, which is the ear with normal hearing. This occurs because the inner ear on the affected side is not able to transmit the sound as effectively as the unaffected side, making the sound seem louder in the ear with better hearing.
Choice d reason:
Lateralization to the left ear in the Weber test would indicate conductive hearing loss in the left ear, not sensorineural hearing loss. In sensorineural hearing loss, the sound vibrates to the ear with better cochlear function, which would be the right ear in this case.

Correct Answer is A

Explanation

Choice a reason:
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones. This can lead to a variety of symptoms, including hoarseness, fatigue, and weight gain. The hoarseness can be due to the effect of hormone deficiency on the vocal cords, while fatigue and weight gain are common due to the slowed metabolism associated with hypothyroidism.

Choice b reason:
Gingivitis is inflammation of the gums and does not typically cause hoarseness, fatigue, or weight gain. It is more commonly associated with symptoms like red, swollen gums and bleeding during brushing or flossing.

Choice c reason:
Aphthous ulcers, also known as canker sores, are small, shallow lesions that develop on the soft tissues in the mouth or at the base of the gums. While they can be painful and cause difficulty with eating and speaking, they do not cause systemic symptoms such as hoarseness, fatigue, or weight gain.

Choice d reason:
Dysphagia, or difficulty swallowing, can lead to hoarseness if there is an associated throat disorder. However, it is not typically associated with systemic symptoms like fatigue and weight gain unless it is part of a broader condition that affects the body's metabolism or energy levels.

A. Overweight B. Obesity Class I C. Normal weight D. Obesity

Correct Answer is A

Explanation

Choice a reason:
A BMI of 27 falls into the 'Overweight' category according to the standard BMI classification. The 'Overweight' range is defined as a BMI of 25 to 29.9. This indicates that the person's weight is higher than what is considered healthy for a given height.

Choice b reason:
'Obesity Class I' is characterized by a BMI of 30 to 34.9. Since the client's BMI is 27, it does not reach the threshold for this category.

Choice c reason:
The 'Normal weight' category ranges from a BMI of 18.5 to 24.9. With a BMI of 27, the client exceeds the upper limit of the normal weight range.

Choice d reason:
The term 'Obesity' generally refers to a BMI of 30 or higher, which encompasses Obesity Class I, II, and III. Since the client's BMI is 27, it is below the obesity range.
