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.)

Answer and Explanation

The Correct Answer is ["3.1"]

1kg = 2.205lbs Weight in kgs= 9.979
Desired dose= 10mg/kg Dose= 99.79mg
Volume= desired dose/ available concentration per ml Volume= 99.79mg/ 32
Volume= 3.12mls
Therefore, the nurse should administer 3.1mls

Correct Answer is C

Explanation

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. Petechial and purpuric rashes are noted on the child's trunk B. Neck flexion causes adduction and flexion movements of the lower extremities C. The child is not able to extend the leg when the thigh is flexed anteriorly at the hip D. The child complains of muscle and joint pain

Correct Answer is C

Explanation

C. This is characteristic of Kernig's sign. Kernig's sign is elicited when the thigh is flexed at the hip and then attempts to extend the leg at the knee are met with resistance or pain due to inflammation of the meninges.

A. Petechial and purpuric rashes are associated with meningococcal meningitis, not specifically with Kernig's sign. These rashes result from bleeding into the skin and are a characteristic feature of meningococcal sepsis. However, they are not directly related to Kernig's sign.
B. This observation describes Brudzinski's sign, not Kernig's sign. Brudzinski's sign occurs when passive flexion of the neck causes involuntary flexion of the hips and knees due to meningeal irritation.
D. Muscle and joint pain can be symptoms of meningitis, but they are not specific to Kernig's sign. Kernig's sign specifically refers to resistance or pain experienced when attempting to extend the leg at the knee.
