A nurse is preparing to administer triamcinolone 40 mg IM to a child. Available is triamcinolone 80 mg/mL. What is the total mL the nurse should 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 ["0.5"]
To calculate the total milliliters of triamcinolone to administer, you would use the formula: \[Total Volume = (Ordered Dose) / (Concentration)\]. For an ordered dose of 40 mg and a concentration of 80 mg/mL, the calculation would be 40 mg divided by 80 mg/mL, which equals 0.5 mL. Therefore, the nurse should administer 0.5 mL of triamcinolone.

Correct Answer is ["300"]
Explanation
To calculate the infusion rate in mL/hr, you can use the formula: (Total Volume in mL) / (Time in hours) = Rate in mL/hr. For lactated Ringer's 150 mL to be infused over 30 minutes, you would first convert the time to hours, which is 0.5 hours (since 30 minutes is half an hour). Then, divide the total volume by the time: 150 mL / 0.5 hours = 300 mL/hr.
Correct Answer is ["3.8"]
Explanation
To calculate the dosage of acetaminophen for the toddler, first convert the weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The toddler weighs 26.4 lbs, which is approximately 12 kg (26.4 lbs ÷ 2.2 lbs/kg). The prescribed dose is 10 mg/kg, so the toddler's dose is 120 mg (12 kg x 10 mg/kg). Since the available medication is 160 mg/5 mL, divide the dose needed by the concentration to find the volume: 120 mg ÷ (160 mg/5 mL) = 3.75 mL. Therefore, the nurse should administer 3.8 mL per dose, rounding to the nearest tenth.
