Question 3 Explanation:

Percent means parts per hundred. 1/125 = x/100 which means 125x = 100 which means x = 0.8

Question 4 |

An order is written for 500 mL of NS to infuse at 40 gtt/min. How long would it take to infuse the NS if the set delivers 10 gtt/mL?

100 minutes | |

125 minutes | |

40 minutes | |

50 minutes |

Question 4 Explanation:

10 gtt/mL means 10 drops per mL. So for 500 mL you will get: 10 X 500 = 5,000 drops. The flow rate is 40 gtt/min, which means 40 drops per minute, so divide total drops by 40 to get the number of minutes: 5,000/40 = 125.
