The nurse is caring for a child who weighs 75 lb. The medication ordered for the child has a therapeutic dosage range of 33 mg/kg per day to 48 mg/kg per day. The medication ordered is to be given 4 times per day. Which dosages would be appropriate for the nurse to administer to this child in one dose?
280 mg per dose.
375 mg per dose.
408 mg per dose.
250 mg per dose.
The Correct Answer is B
Choice A reason: For a 75-lb child (34 kg), the daily dose range is 1122-1632 mg (33-48 mg/kg). Divided by 4, each dose is 280.5-408 mg. 280 mg is slightly below the minimum, making this borderline and incorrect compared to a dose within the safe therapeutic range for administration.
Choice B reason: A 75-lb child weighs 34 kg (75 ÷ 2.2). The daily dose range is 1122-1632 mg (33-48 mg/kg), so per dose (÷4) is 280.5-408 mg. 375 mg falls within this range, aligning with pediatric pharmacology, making it the correct dosage to administer per dose.
Choice C reason: For a 75-lb child (34 kg), the daily dose range is 1122-1632 mg (33-48 mg/kg), with each dose (÷4) being 280.5-408 mg. 408 mg is at the maximum but within range, making this correct but less optimal than 375 mg, which is safer within the therapeutic window.
Choice D reason: A 75-lb child (34 kg) requires 1122-1632 mg daily (33-48 mg/kg), so each dose (÷4) is 280.5-408 mg. 250 mg is below the minimum, risking underdosing, making this incorrect compared to 375 mg, which is safely within the therapeutic range for the child.

Correct Answer is B
Explanation
Choice A reason: Saying the flowers aren’t alive and removing them avoids the child’s question, missing a chance to discuss death. Asking about dying opens dialogue, making this evasive and incorrect compared to the nurse’s opportunity to engage the dying child in a meaningful conversation.
Choice B reason: Acknowledging the flowers’ death and asking what dying is like invites the child to share thoughts, facilitating discussion about their own mortality. This aligns with pediatric palliative care communication, making it the most appropriate response to encourage the child to open up about dying.
Choice C reason: Calling the flowers uncheerful and removing them dismisses the child’s observation, closing off discussion about death. Asking about dying fosters dialogue, making this superficial and incorrect compared to the nurse’s role in supporting the dying child’s emotional expression and exploration.
Choice D reason: Offering to trash the flowers ignores the child’s reference to death, missing a chance to explore their thoughts. Asking about dying encourages openness, making this abrupt and incorrect compared to the nurse’s opportunity to facilitate a conversation about death with the child.
Correct Answer is C
Explanation
Choice A reason: Picking up the child without assessment risks disrupting a potentially critical condition, as quiet lying may indicate pain or altered consciousness. Checking consciousness and pain ensures safety, making this premature and incorrect compared to prioritizing a thorough evaluation of the child’s quiet state.
Choice B reason: Leaving the child in a flexed position assumes no issue without assessing consciousness or pain, which quiet behavior may mask. Evaluating the child’s status is critical, making this passive and incorrect compared to actively checking for underlying issues in the child’s quiet presentation on the bed.
Choice C reason: Checking the level of consciousness and pain scale determines if the child’s quietness indicates distress, pain, or neurological issues, ensuring appropriate care. This aligns with pediatric assessment protocols, making it the correct action to address the child’s condition lying quietly on the bed.
Choice D reason: Assuming the child is sleeping on the parent’s lap is incorrect, as the child is on the bed, and quietness may indicate distress. Assessing consciousness and pain is essential, making this inaccurate and incorrect compared to evaluating the child’s true condition in this scenario.
