What assessment is best for distinguishing between hypoxemia and hypercapnia?

A. Meconium ileus is a common early sign of cystic fibrosis in newborns. It occurs when the meconium, which is the first stool of a newborn, becomes thick and sticky, leading to a blockage in the intestines. This is often one of the first signs of cystic fibrosis in infants.

B. Cyanosis, while indicative of oxygenation problems, is not a specific sign of cystic fibrosis in newborns. It may be seen in many respiratory or cardiac conditions.

C. Yellow, seedy, loose stools are more commonly associated with normal newborn digestion or conditions like lactose intolerance or gastrointestinal infections, not specifically cystic fibrosis.

D. Coughing is a symptom of cystic fibrosis, but it typically develops later as the disease progresses and affects the lungs, rather than being an early sign in newborns.

A. Overactive bladder refers to the condition where there is a sudden and uncontrollable urge to urinate, often associated with urgency and frequency, but it is not caused by exertional stimuli.

B. Stress incontinence is the type of urinary incontinence that occurs when physical activity or exertion, such as coughing, sneezing, laughing, or lifting, increases abdominal pressure and leads to involuntary leakage of urine.

C. Functional incontinence refers to the inability to reach the bathroom in time due to physical or cognitive impairments, such as mobility issues or dementia, rather than exertional triggers.

D. Urge incontinence is the sudden and intense urge to urinate, often leading to involuntary loss of urine. It is not typically caused by exertion but by an overactive bladder.
