A nurse is converting an infant's weight in lb and oz to kg. The infant weighs 9 lb
4 oz. What is the infant's weight in kg? (Round to the nearest tenth.)
4.2 kg
Rationale:
1. 9 lb 4 oz = 9 + (4/16) lb = 9.25 lb
2. 9.25/2.2 = x
3. x = 4.204545 kg
4. x = 4.2 kg (rounded)
A nurse is preparing to administer immunizations to a preschooler. Which of the
following actions should the nurse take?
A. Request the preschooler's parent leave the room during the injections.
B. Tell the preschooler that the injections are not going to hurt.
C. Tell the preschooler to remain quiet during the injections.
D. Have the preschooler blow bubbles during the injections.
D. Have the preschooler blow bubbles during the injections.
Rationale:
A. The nurse should allow the preschooler's parents to stay with the preschooler during
injections to decrease the child's anxiety and pain. The parent should reassure the
preschooler by speaking softly and remaining close.
B. The nurse should not tell the preschooler that the injections will not hurt. The nurse
should tell the preschooler what the injections might feel like using non-pain descriptors,
such as hot or sharp.
C. The nurse should encourage the preschooler to verbalize pain during the injections.
The nurse should tell the child to concentrate on yelling at a volume that corresponds
with the level of pain they are feeling.
D. The nurse should use distraction as a nonpharmacological pain management
technique for a preschooler. The nurse should have the preschooler blow bubbles
during the injections.
A nurse is preparing to administer 0.9% sodium chloride (0.9% NaCl) 15 mL/kg IV
to infuse over 8 hours to a school-age kid who weighs 22 kg. The nurse should
set the IV pump to deliver how many mL/hour? (Round to the nearest whole
number.)
41 mL/hour
Rationale:
1. (15 mL/kg) x (22 kg) = 330 mL
, 2. 330 mL/8 hours = x
3. x = 41.25 mL/hour
4. x = 41 mL/hour (rounded)
A charge nurse is reviewing techniques for the safe administration of
medications to children with a newly licensed nurse. Which of the following
statements should the nurse make?
A. "Confirm chemotherapy medication dosages using a body surface area
nomogram."
B. "Ask preschoolers their name to confirm their identity prior to administering
medication."
C. "Calculate medication dosages based on a child's age, not their weight."
D. "Use paper cups to administer liquid dosages of medications."
A. "Confirm chemotherapy medication dosages using a body surface area nomogram."
Rationale:
A. The nurse should use a nomogram to calculate a child's body surface area prior to
administering high risk medications, such as chemotherapy, to ensure safe
administration of medication.
B. The nurse should ask the parent or guardian of a preschooler to confirm the child's
identity prior to administering medications. A preschooler might inadvertently provide
the wrong name when asked.
C. The nurse should calculate medication dosages based on a child's weight, not their
age, due to differences in size of children of the same age.
D. The nurse should use plastic cups to administer medications to children. Paper cups
should not be used for administering liquid medications, because they are not sturdy
and can collapse.
A nurse is converting a preschool-age child's weight in lb to kg. The preschool-
age child weighs 44 lb. How many kg does the child weigh?
20 kg
Rationale:
1. 44/2.2 = x
2. x = 20 kg
A nurse is preparing to administer D5W 7 mL/kg to infuse over 6 hours to a
toddler who weighs 11 kg. The nurse should set the IV pump to deliver how many
mL/hour? (Round to the nearest whole number.)
13 mL/hour
Rationale:
1. (7 mL/kg) x (11 kg) = 77 mL
2. 77 mL/6 hours = x
3. x = 12.833333 mL/hour
4. x = 13 mL/hour (rounded)
A nurse is converting an infant's weight from lb and oz to kg. The infant weighs
13 lb 8 oz. How many kg does the infant weigh? (Round to the nearest tenth.)
