A nurse is preparing to administer vancomycin 50 mg PO daily divided into four equal doses. The amount available is vancomycin 125 mg capsules. How many capsules should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Convert the client’s weight from pounds to kilograms. 198 lb ÷ 2.2 = 90 kg

Result: 90 kg

Step 2: Calculate the total daily dose of vancomycin. 15 mg × 90 kg = 1350 mg/day

Result: 1350 mg/day

Step 3: Divide the total daily dose by 2 to get the dose per administration (since it is given every 12 hours). 1350 mg/day ÷ 2 = 675 mg

Result: 675 mg

Final Answer: The nurse should administer 675 mg of vancomycin with each dose.

Choice A reason:

The statement “Provide bedtime rituals” is correct. Establishing a consistent bedtime routine can help toddlers feel more secure and relaxed, which can promote better sleep. Bedtime rituals might include reading a story, singing a lullaby, or having a warm bath before bed. These activities signal to the child that it is time to wind down and prepare for sleep.

Choice B reason:

The statement “Encourage play exercises in the evening” is incorrect. While physical activity is important for overall health, engaging in stimulating play exercises right before bedtime can make it harder for toddlers to settle down and fall asleep. It is better to encourage quiet, calming activities in the evening.

Choice C reason:

The statement “Explain the source of the toddler’s fears” is not the most effective approach for promoting sleep. While addressing fears is important, the explanation alone may not be sufficient to help the toddler feel secure enough to sleep. Providing comfort and reassurance through bedtime rituals is more effective in creating a sense of safety.

Choice D reason:

The statement “Turn off the room light” is partially correct but not the best standalone solution. While a dark environment can promote sleep, some toddlers may feel more secure with a nightlight. The focus should be on creating a calming and comfortable sleep environment, which includes but is not limited to adjusting the lighting.
