The nurse is assessing the chest shape of a patient.
Which chest configuration describes a sunken in sternum and costal cartilage?

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.

Choice A rationale

An elliptical chest describes the typical shape of a healthy chest with a lateral dimension greater than the anteroposterior dimension. This shape allows for normal expansion and contraction of the lungs during breathing. An elliptical chest does not indicate any deformity or abnormality in the sternum or costal cartilage.

Choice B rationale

Pectus excavatum, also known as funnel chest, is a congenital deformity where the sternum and costal cartilage are sunken inward, creating a concave appearance of the chest. This condition can range in severity and may affect respiratory function and exercise tolerance in some individuals. Surgical correction may be considered for severe cases.

Choice C rationale

A standard chest describes a chest without any deformities or abnormalities, typically with a normal elliptical shape. This term does not denote any specific condition or configuration and implies a healthy, non-deformed chest.

Choice D rationale

Barrel chest is characterized by an increased anteroposterior diameter of the chest, giving it a round or barrel-like appearance. This condition is often seen in individuals with chronic obstructive pulmonary disease (COPD) or emphysema, where the lungs are chronically overinflated, causing the chest to expand and lose its normal shape.
