A nurse expects to hear which percussion sounds over muscles and tissues?

Choice A rationale

Vitiligo is a condition caused by the destruction or malfunction of melanocytes, the cells responsible for producing melanin pigment. This leads to the development of white patches on the skin, as melanin is absent in these areas. Vitiligo is an autoimmune condition and can affect any part of the body, including the skin, hair, and mucous membranes.

Choice B rationale

Excess apocrine glands in the feet are not related to vitiligo. Apocrine glands are sweat glands found primarily in the underarm and genital areas and are responsible for the secretion of a thick, odorless fluid. Their overactivity does not result in the white patches seen in vitiligo.

Choice C rationale

Impetigo is a bacterial skin infection characterized by red sores, blisters, and crusting. It is not related to vitiligo and does not cause depigmentation. Impetigo is treated with antibiotics, whereas vitiligo requires different management strategies to address the loss of pigment.

Choice D rationale

Vitiligo is not caused by an excess of melanin pigment. Rather, it is the result of melanin loss or the absence of melanocytes in certain areas of the skin, leading to the characteristic white patches.

Choice A rationale

Functional incontinence occurs when an individual cannot reach the bathroom in time due to physical or cognitive limitations. It is not related to stress or pressure on the bladder but rather to external factors that impede timely access to toileting facilities.

Choice B rationale

Reflex incontinence is characterized by involuntary loss of urine due to a lack of signal awareness or detrusor muscle overactivity. It is typically associated with neurological conditions such as spinal cord injuries or multiple sclerosis. This type of incontinence does not involve stress-related triggers like coughing or sneezing.

Choice C rationale

Stress incontinence involves the involuntary leakage of urine during activities that increase intra-abdominal pressure, such as coughing, sneezing, laughing, or physical exertion. This type of incontinence is commonly seen in women, particularly after childbirth or during menopause, due to weakened pelvic floor muscles or sphincter dysfunction.

Choice D rationale

Urge incontinence is characterized by a sudden and intense urge to urinate, often resulting in involuntary urine leakage before reaching the bathroom. It is typically caused by overactive bladder muscles or nerve signals and is not specifically triggered by actions like coughing or sneezing.
