A nurse is preparing to administer 5 mL of digoxin elixir PO to a toddler. The nurse should recognize that this is equivalent to how many tsp? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

The conversion of milliliters to teaspoons is a common calculation in medical dosing. For the administration of 5 mL of digoxin elixir PO, the equivalent in teaspoons would be approximately 1.01442 teaspoons. When rounding to the nearest whole number, as per medical dosing guidelines which often require precise measurements to ensure safety, the amount would be 1 teaspoon. It's important to use a leading zero if it applies to indicate less than one, and not to use a trailing zero as it could be mistaken for a larger dose. Therefore, the nurse should recognize that 5 mL is equivalent to 1 teaspoon.

Correct Answer is ["1"]

Explanation

To calculate the dosage of phenytoin for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 38 lb, which is approximately 17.27 kg (38 lb / 2.2). Next, multiply the child's weight in kilograms by the dosage prescribed: 5 mg/kg/day. For this child, that would be 86.36 mg/day (17.27 kg * 5 mg/kg). Since the dose is divided every 12 hours, the amount per dose would be 43.18 mg (86.36 mg/day divided by 2). With phenytoin 50 mg chewable tablets available, the nurse would administer one tablet per dose.

Correct Answer is ["3.9"]

Explanation

To calculate the dosage of prednisolone syrup for the toddler, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The toddler weighs 26 pounds, which is approximately 11.82 kilograms (26 / 2.2). The prescribed dose is 2 mg/kg/day, so the total daily dose is 23.64 mg (11.82 kg * 2 mg). This total daily dose should be divided into two equal doses to be given every 12 hours, resulting in 11.82 mg per dose. With the prednisolone syrup concentration of 15 mg/5 mL, use the formula: (desired dose * volume of one dose) / concentration of the drug to find the volume of syrup per dose. Therefore, the volume for each dose is (11.82 mg * 5 mL) / 15 mg, which equals 3.94 mL. After rounding to the nearest tenth, the nurse should administer 3.9mL per dose.
