HESI RN Nursing Care of Children Exam
VERSION 15
- / 3
- "Your child should be able to scribble spontaneously using a crayon at the age of
15 months."
Rationale: The nurse should teach the parent that at the age of 15 months, the toddler should be able to scribble spontaneously, and at the age of 18 months, the toddler should be able to make strokes imitatively.
- A nurse is caring for a toddler and is preparing to administer 0.9% sodium chloride 100 mL IV
to infuse over 4 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) 25 gtt
Rationale: 100ml/4 hr x 60gtt/1mlx 1 hr/60min= 6000/240= 25 gtt
Ratio and Proportion
STEP 1: What is the unit of measurement to calculate? gtt/min
STEP 2: What is the volume needed? 100 mL
STEP 3: What is the total infusion time? 4 hr
STEP 4: Should the nurse convert the units of measurement? Yes (min does not equal hr)
- hr/60 min = 4 hr/X min
X = 240 min
STEP 5: Set up an equation and solve for X. 2 / 3
Volume (mL)/Time (min) = drop factor (gtt/mL) = X 100 mL/240 min x 60 gtt/mL = X gtt/min
X = 25
STEP 6: Round if necessary.
STEP 7: Reassess to determine whether the amount to administer makes sense. If the prescription reads 100 ml of 0.9% sodium chloride IV to infuse over 4 hr, it makes sense to administer 25 gtt/min. The nurse should set the manual IV infusion to deliver0.9% sodium chloride IV at 25 gtt/min.
Dimensional Analysis
STEP 1: What is the unit of measurement to calculate? gtt/min
STEP 2: What is the volume needed? 100 mL
STEP 3: What is the total infusion time? 4 hr
STEP 4: Should the nurse convert the units of measurement? Yes (min does not equal hr)
STEP 5: Set up an equation and solve for X.
X = Quantity / 1 mL x Conversion (hr) / Conversion (min) x Volume (mL) / Time (hr) X gtt/min = 60 gtt/1 mL x 1 hr/ 60 min x 100 mL/4 hr X = 25
