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.)

A. Kawasaki disease is a systemic vasculitis that predominantly affects medium-sized arteries, including the coronary arteries of the heart. The inflammation of the blood vessels can lead to coronary artery aneurysms and other cardiovascular complications if not promptly treated.

B. The respiratory system is not primarily affected by Kawasaki disease. While Kawasaki disease is a systemic illness that can cause fever and inflammation, it primarily affects the cardiovascular system, with inflammation of blood vessels, particularly the coronary arteries.

C. The integumentary system (skin, hair, nails) is not primarily affected by Kawasaki disease. Although some children with Kawasaki disease may develop a rash, particularly in the acute phase of the illness, skin involvement is not the primary feature of the disease.

D. Gastrointestinal symptoms, such as abdominal pain, vomiting, or diarrhea, can occur in Kawasaki disease but they are not the primary focus of the disease. Kawasaki disease primarily affects the cardiovascular system, leading to inflammation of blood vessels and potential complications such as coronary artery aneurysms.

A. Decreased cardiac output in heart failure can lead to poor perfusion of the extremities, resulting in cool skin and decreased urine output due to reduced renal perfusion and impaired kidney function.

D. Poor feeding is often observed due to increased respiratory effort, tachypnea, and fatigue associated with heart failure. Additionally, infants may exhibit failure to thrive or inadequate weight gain despite increased caloric intake due to metabolic demands and inefficient utilization of nutrients.

E. Tachypnea and respiratory distress occur due to pulmonary congestion and increased respiratory effort in response to heart failure. Infants may exhibit signs such as nasal flaring, grunting, retractions, and cyanosis.

B. Bradycardia and hypotension are not typical manifestations of heart failure in infants. Instead, infants with heart failure often present with tachycardia (rapid heart rate) as a compensatory mechanism to maintain cardiac output. Hypotension may occur in severe cases but is not a common finding.

C. Increased appetite and excessive weight gain are not typical manifestations of heart failure in infants. Infants with heart failure often experience poor feeding and failure to thrive due to inadequate cardiac output and oxygen delivery to meet metabolic demands.
