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 B
Explanation
B. The correct angle for insulin injections is typically 90 degrees when administering into areas with adequate subcutaneous tissue, such as the abdomen or thigh.
A. Insulin injections should not be administered rapidly, as this can cause discomfort or bruising at the injection site. Additionally, a 20-gauge needle is too large for insulin injections, which typically require smaller gauge needles.
C. Insulin injections are typically administered using insulin syringes, not tuberculin syringes. Additionally, the recommended angle for insulin injections is 90 degrees, not 15 degrees.
D. The Z-track method is a technique used to minimize medication leakage or staining of the skin when administering certain medications, particularly those with irritating properties or medications given intramuscularly.
