A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.2"]
Toddler's weight: 26.4 lb
1 lb = 0.453592 kg (conversion factor)
Weight in kilograms = 26.4 lb × 0.453592 kg/lb ≈ 11.979 kg
Calculate the total dosage based on the toddler's weight:
Total dosage = 10 mg/kg × 11.979 kg
≈ 119.79 mg
Determine the volume of acetaminophen solution needed based on the concentration provided: Available concentration: 80 mg/0.8 mL
Dosage required: 119.79 mgUsing the formula:
Volume (mL) = Dosage required (mg) / Concentration (mg/mL)
= 119.79 mg / 80 mg/0.8 mL
≈ 1.2 mL

Correct Answer is A
Explanation
A. Nystatin oral suspension is typically swished around the mouth before swallowing to ensure adequate coverage of affected areas, such as the oral mucosa. This helps to maximize the medication's contact with fungal infections in the mouth.
B. This instruction is not necessary for nystatin oral suspension. Nystatin oral suspension can be taken with or without food, as directed by the healthcare provider. Therefore, there is no specific requirement to take it with meals.
C. This instruction is not necessary for nystatin oral suspension. Using a straw is not typically recommended for taking oral medications unless specifically instructed by a healthcare provider. Therefore, this instruction is not relevant to the administration of nystatin oral suspension.
D. This instruction is not necessary for nystatin oral suspension. While drinking water after taking medication is generally a good practice to ensure proper swallowing and hydration, it is not specifically required for nystatin oral suspension.
Correct Answer is D
Explanation
D. Chills are a hallmark sign of febrile nonhemolytic reactions. These reactions typically present with fever, chills, and occasionally rigors (shivering). They are caused by recipient antibodies reacting to donor leukocytes or cytokines present in the transfused blood components.
A. Dyspnea (difficulty breathing) is not typically associated with febrile nonhemolytic reactions. It is more commonly seen in acute hemolytic reactions or transfusion-related acute lung injury (TRALI).
B. Urticaria (hives) is more commonly associated with allergic transfusion reactions rather than febrile nonhemolytic reactions.
C. Vomiting is not a characteristic feature of febrile nonhemolytic reactions. It may occur in some cases of transfusion reactions, but it is not specific to febrile nonhemolytic reactions.
