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.

Correct Answer is ["30"]

Explanation

To calculate the dosage of dexamethasone in milliliters for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 66 pounds, which is approximately 30 kilograms (66 / 2.2). According to the prescription, the child requires 0.2 mg of dexamethasone per kilogram per day. So, for a 30 kg child, the total daily dosage is 6 mg (30 kg * 0.2 mg/kg). This total daily dose should be divided into two doses, which means each dose will be 3 mg (6 mg / 2). Given that the available elixir concentration is 0.5 mg per 5 mL, to administer a 3 mg dose, the nurse would need 30 mL of the elixir (3 mg / 0.5 mg * 5 mL). Therefore, the nurse should administer 30 mL per dose.

A. Give the client two troches in the morning and two troches in the evening. B. Withhold oral intake until the troche dissolves in the client's mouth. C. Tell the client to keep the troche under the tongue for 5 min before swallowing it. D. Instruct the client to swallow the troche with 240 mL. (8 oz) water.

Correct Answer is B

Explanation

A. Give the client two troches in the morning and two troches in the evening. This option misinterprets the frequency of administration; the prescription is for four times a day, not twice.
B. Withhold oral intake until the troche dissolves in the client's mouth. Nystatin troches are designed to dissolve slowly in the mouth, allowing the medication to come into contact with the mucous membranes to treat fungal infections effectively. The client should avoid eating or drinking until the troche has fully dissolved to ensure maximum effectiveness.
C. Tell the client to keep the troche under the tongue for 5 min before swallowing it. Troches should dissolve completely in the mouth, not just be held under the tongue for a specific time.
D. Instruct the client to swallow the troche with 240 mL (8 oz) water. Troches should not be swallowed whole with water; they need to dissolve in the mouth to be effective.
