A nurse is preparing to administer acetaminophen 10/mg/kg PO to a preschool child for fever. The child weighs 22 lb. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

C. Muscle weakness and lack of coordination contribute to difficulties with balance and coordination, leading to frequent falls and clumsiness in children with DMD.

A. DMD typically presents with symptoms such as difficulty climbing stairs, a waddling gait, and calf muscle hypertrophy, rather than atrophy.

B. Delayed fine-motor development is not a typical manifestation of Duchenne muscular dystrophy. DMD primarily affects muscle strength and function rather than fine motor skills.

D. Ambulating by holding onto furniture is not typical in Duchenne muscular dystrophy. As the disease progresses, children with DMD typically experience difficulty walking and may eventually require the use of assistive devices such as wheelchairs or orthoses for mobility.

A. Wheezing. Cystic fibrosis can cause airway obstruction due to thickened mucus, leading to wheezing and difficulty breathing, especially during respiratory infections or exacerbations.

B. A barrel-shaped chest is often seen in advanced stages of cystic fibrosis. It results from hyperinflation of the lungs due to air trapping, chronic lung disease, and repeated respiratory infections. The chest appears rounded and enlarged, similar to the shape of a barrel.

D. Clubbing of fingers and toes is a common finding in cystic fibrosis. It is caused by chronic hypoxia and inadequate oxygenation of tissues, leading to changes in the nail beds and fingertips. Clubbing typically develops over time in individuals with chronic respiratory conditions, including cystic fibrosis.

C. Thin, watery mucous is not expected in cystic fibrosis. Instead, cystic fibrosis is characterized by thick, sticky mucus due to dysfunction of the exocrine glands, leading to blockages in the airways, pancreas, and other organs.

E. Rapid growth spurts are not typically associated with cystic fibrosis. In fact, children with cystic fibrosis may experience growth failure or delayed growth due to malabsorption of nutrients, chronic illness, and increased energy expenditure.
