ATI PN NURSING CARE OF CHILDREN PROCTORED EXAM VERSION 4 d. "Your child should be able to scribble spontaneously using a crayo n at the age of 15 months." Rationale: The nurse should teach the parent that at the age of 15 month s, the toddler should be able to scribble spontaneou sly, and at the age of 18 month s, the toddler should be able to make stroke s imitatively. 3. A nurse is caring for a toddler and is preparing to admini ster 0.9% sodium chloride 100 mL IV to infu se over 4 hr. The drop factor of the manual IV tubing i s 60 gtt/ mL. The nur se should set the manual IV infusion to deliver how many gtt /min? (Round the answer to the nearest who le number. U se a leading zero if it applies. Do not u se a tr ailing z ero.) 25 gtt Rationale: 100ml/4 hr x 60gtt/1 mlx 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 vol ume n eeded? 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) 1 hr/60 min = 4 hr/X min X = 240 min STEP 5: Set up an equation and solve for X. Volume (mL)/Time (min) = drop factor (gtt/mL) = X 100 mL/240 m in x 60 gtt/mL = X gtt /min X = 25 STEP 6: Round if necessary. STEP 7: Reassess to determine wh ether the amount to admini ster 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 d eliver0.9% 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 vol ume n eeded? 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 equ ation 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
