A patient came with a right ear sensorineural hearing loss. What should the nurse expect while performing the Weber test?

lateralization of the sound/vibration to both ears equally

lateralization of the sound/vibration to the left ear.

bone conduction(BC) is greater than air conduction (AC)

lateralization of the sound/vibration to the right ear.

Answer and Explanation

The Correct Answer is B

A) Lateralization of the sound/vibration to both ears equally: The Weber test is used to assess unilateral hearing loss and would not show equal lateralization in the presence of unilateral sensorineural hearing loss. Equal lateralization would suggest normal hearing or symmetrical hearing loss, which is not the case here.
B) Lateralization of the sound/vibration to the left ear: In sensorineural hearing loss, sound is perceived to lateralize to the unaffected ear. Therefore, with right ear sensorineural hearing loss, the sound will lateralize to the left ear, indicating that the left ear has better hearing capability.
C) Bone conduction (BC) is greater than air conduction (AC): This finding is characteristic of conductive hearing loss, not sensorineural hearing loss. In sensorineural hearing loss, air conduction is typically greater than or equal to bone conduction, but the Weber test focuses on lateralization rather than BC versus AC.
D) Lateralization of the sound/vibration to the right ear: If the sound were to lateralize to the affected ear in sensorineural hearing loss, it would suggest that the affected ear is hearing better, which contradicts the nature of sensorineural hearing loss. The sound will actually lateralize to the better-hearing, unaffected ear.

Correct Answer is A

Explanation

A) Asymmetrical shape: One of the key "ABCD" characteristics of malignant melanoma is asymmetry. Melanomas often have an irregular shape where one half does not match the other, unlike benign moles, which are typically symmetrical. This characteristic helps in distinguishing malignant lesions from benign ones.
B) Diameter less than 6mm: Malignant melanomas are often larger than 6 mm in diameter, especially as they progress. While smaller lesions can still be malignant, a diameter less than 6 mm is not a distinguishing feature for melanoma. Typically, melanomas are identified as growing larger over time.
C) Color is uniform: Malignant melanomas usually exhibit multiple colors or uneven pigmentation rather than uniform color. Uniform color is more characteristic of benign moles. Melanomas can show a mix of colors, including shades of brown, black, and sometimes red or white.
D) Borders well demarcated: Malignant melanoma often has irregular, not well-defined borders. The edges of a melanoma are usually uneven or not clearly defined, unlike benign moles, which typically have smooth, well-demarcated borders.

A. Pelvic examination B. Transillumination C. Bladder percussion D. Digital rectal examination

Correct Answer is D

Explanation

A. Pelvic examination: A pelvic examination is generally used to assess the reproductive organs in females rather than the prostate. It does not provide a direct assessment of the prostate gland in males.
B. Transillumination: Transillumination is a technique used to detect fluid-filled cysts or masses in areas such as the scrotum or breast. It is not used to assess the prostate gland.
C. Bladder percussion: Bladder percussion is used to assess bladder size and fullness, typically to diagnose conditions related to bladder dysfunction. It does not provide information about the prostate.
D. Digital rectal examination: A digital rectal examination (DRE) is the standard method used to assess the size, shape, and consistency of the prostate gland. It allows the clinician to feel the prostate through the rectal wall and is essential for evaluating prostate health.
