A nurse is preparing to administer acetaminophen 15 mg/kg PO to a preschool child for fever. The child weighs 30 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.)
The Correct Answer is ["6.4"]
Convert the child's weight from pounds to kilograms:
Weight in pounds: 30 lb
Conversion: 1 lb ≈ 0.454 kg
Weight in kg: 30 lb× 0.454 kg/lb =13.62 kg
30lb×0.454kg/lb=13.62kg
Calculate the dose in mg:
Dose: 15 mg/kg
15 mg/kg ×13.62kg=204.3 mg
Determine the volume to administer:
Available concentration: 160 mg/5 mL
Volume in mL:
204.3 mg ÷160 mg/5 mL
= 204.3mg×5ml ÷160mg
=6.4mL
The nurse should administer 6.4 mL of acetaminophen.

Correct Answer is D
Explanation
A. Stand above the child's eye level when speaking: The nurse should be at eye level with the child to facilitate lip reading and better communication.
B. Talk directly into the child's impaired ear: This can be uncomfortable and is not effective. The nurse should speak directly to the child, allowing them to use any residual hearing or hearing aids.
C. Speak loudly to the child: Speaking loudly can distort the sounds and make understanding more difficult for hearing-impaired individuals.
D. Speak slowly while facing the child: Speaking slowly and facing the child ensures that they can read lips and facial expressions, which aids in understanding.
Correct Answer is C
Explanation
A. "You will need to take the entire prescription of antibiotics even if your symptoms improve." Atopic dermatitis is typically not treated with antibiotics unless there is a secondary bacterial infection. The standard treatment usually involves topical corticosteroids and emollients.
B. "The doctor will remove the lesions with liquid nitrogen." This is incorrect as liquid nitrogen is used for treating warts and certain types of skin lesions, not atopic dermatitis.
C. "The doctor might recommend an antihistamine to help control your symptoms." This is a correct statement. Antihistamines can help reduce itching and provide relief, which is a common symptom of atopic dermatitis.
D. "You can relieve your child's discomfort by applying warm compresses to the lesions." Warm compresses are not typically recommended for atopic dermatitis. Cool compresses or baths are more beneficial to reduce itching and inflammation.
