A nurse is preparing to administer fluconazole 42 mg PO to an infant. The nurse should recognize that this is equivalent to how many g? (Round the answer to the nearest thousandth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.042"]

To convert milligrams (mg) to grams (g), one must remember that 1 gram is equivalent to 1000 milligrams. Therefore, to find the equivalent in grams for 42 mg, the amount in milligrams should be divided by 1000. Doing the math, 42 mg divided by 1000 gives 0.042 grams. When rounding this to the nearest thousandth, it remains 0.042, as the fourth decimal place is not significant enough to round up the third decimal place. Hence, 42 mg is equivalent to 0.042 g.

Explanation

To calculate the volume of penicillin G benzathine injection required, divide the prescribed dose by the concentration available. In this case, 1,200,000 units prescribed divided by 600,000 units per mL results in 2 mL.

Correct Answer is ["1.2"]

Explanation

To calculate the dosage of prochlorperazine for the adolescent, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The adolescent weighs 103 lb, which is approximately 46.82 kg (103 ÷ 2.2). Next, multiply the weight in kilograms by the dosage prescribed, which is 0.13 mg/kg. This results in a total dosage of 6.09 mg (46.82 kg × 0.13 mg/kg). Finally, divide the total dosage by the concentration of the available medication to find out how many mL to administer. The available prochlorperazine injection has a concentration of 5 mg/mL, so you would administer 1.22 mL (6.09 mg ÷ 5 mg/mL). Rounded to the nearest tenth, the nurse should administer 1.2 mL per dose.
