A nurse is caring for a preschooler who has heart failure and a new prescription for furosemide 4 mg/kg every 8 hr. The child weighs 16 kg (35 lb). Available is furosemide oral solution 40 mg/5 mL. How many mL 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.)
The Correct Answer is ["8"]
Calculation:
- Calculate the desired dose in milligrams (mg) per administration.
Desired dose (mg) = 4 mg/kg × 16 kg
= 64 mg.
Available concentration of the medication = 40 mg/5 mL.
- Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL))
= 64 mg / (40 mg / 5 mL)
= 8 mL.

Correct Answer is ["A","C","E"]
Explanation
A. Ensure the scale is balanced to "0" before weighing the infant: It is important to calibrate the scale to "0" before weighing the infant to ensure an accurate measurement. This step helps to avoid any errors in weight assessment.
B. Place a stadiometer on the top of the infant's head to measure their length: A stadiometer is typically used for measuring height in older children and adults, but for infants, a length board (not a stadiometer) should be used.
C. Cover the scale with a clean sheet of paper: This is essential for hygiene and to provide a clean, warm surface for the infant, especially when they are undressed for weighing.
D. Obtain the infant's weight with their diaper on: To obtain an accurate weight, the infant should be weighed without the diaper. A diaper adds weight that could affect the accuracy of the measurement.
E. Measure the infant's length from the crown of the head to the heels of the feet: For accurate length measurements in infants, the measurement should be taken from the crown of the head to the heels of the feet while the infant is lying flat on a length board.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"C"}
Explanation
Rationale for Correct Choices:
- Consult the child life specialist for guidance: A child life specialist can help the parent navigate the difficult conversation with their adolescent, providing strategies for addressing sensitive topics like metastasis and death.
- Reinforce teaching to the parent regarding the adolescent's potential emotional responses: Educating the parent on common emotional responses helps them prepare for and better support their adolescent through this challenging time.
Rationale for Incorrect Choices:
- Encourage the parent to hide their emotions from their adolescent: Hiding emotions can create barriers to trust and communication, which can make the adolescent feel isolated or confused.
- Instruct the parent to withhold the test results from their adolescent: Withholding important information can prevent the adolescent from understanding their condition and making informed decisions about their care.
- Discourage the parent from discussing the possibility of death with their adolescent: Avoiding discussions about death can prevent the adolescent from processing their emotions and understanding the reality of their situation.
- Collaborate with the RN to initiate a referral for admission to hospice care: Hospice care should only be considered after emotional support and clear communication have been established, not prematurely without addressing emotional needs first.
