A client is to receive LR 1000 ml over 8 hours. The IV tubing drop rate is 60 gtts/ml. What is the correct rate (gtts/min)? DOCUMENT ANSWER AS: RATE gtts/min (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 ["125"]
Calculate the total volume to be infused in drops.
Total drops = Total volume (mL) × Drop factor (gtts/mL)
= 1000 mL × 60 gtts/mL
= 60000 gtts
Calculate the total infusion time in minutes.
Total infusion time (minutes) = Total hours × 60 minutes/hour
= 8 hours × 60 minutes/hour
= 480 minutes
Calculate the IV flow rate in drops per minute (gtts/min).
IV rate (gtts/min) = Total drops / Total infusion time (minutes)
= 60000 gtts / 480 minutes
= 125
=125 gtts/min

Correct Answer is ["35"]
Explanation
Calculate the total infusion time in minutes.
Infusion time in minutes = 2 hours × 60 minutes/hour
= 120 minutes
Calculate the total number of drops to be infused.
The total volume remaining is 350 mL
Drip factor is 12 gtts/mL.
Total drops = Total volume (mL) × Drop factor (gtts/mL)
Total drops = 350 mL × 12 gtts/mL
= 4200 gtts
Calculate the IV flow rate in drops per minute (gtts/min).
IV rate (gtts/min) = Total drops / Total infusion time (minutes)
= 4200 gtts / 120 minutes
= 35
=35 gtts/min
Correct Answer is B
Explanation
A. surgery has caused an episode of supraventricular tachycardia: While stress or surgery can trigger arrhythmias, the ECG shown demonstrates a sinus tachycardia pattern (narrow QRS complexes with identifiable P waves before each QRS), not supraventricular tachycardia (SVT), which typically has a very rapid, regular rhythm often without visible P waves.
B. is febrile which is causing the heart rate to be elevated: The client has a temperature of 102°F (38.8°C), which can increase metabolic demand and lead to sinus tachycardia. Fever is a common and expected cause of elevated heart rate, especially when accompanied by infection, such as the client’s post-op wound infection.
C. is in heart failure and the heart rate is elevated to compensate: There is no evidence from the scenario (no dyspnea, crackles, edema, or reduced BP) that supports heart failure. The elevated HR is more directly related to the fever and infection, not cardiac decompensation.
D. probably has a low oxygen saturation causing an increased respiratory rate: The respiratory rate is slightly elevated (22/min), but there is no mention of hypoxia or oxygen saturation levels. Tachycardia secondary to hypoxia would require clinical indicators of respiratory distress or desaturation, which are not demonstrated.
