Question 1 of 5
The healthcare provider has ordered 1000 mL of 0.9% sodium chloride to be administered intravenously over 5 hours. The drop factor on the tubing is 15 drops/mL. How many milliliters per hour and how many drops per minute will you administer?
Correct Answer: 1000 mL ÷ 5 hr = 200 mL/hr. 200 mL/hr ÷ 60 min = 3.33 mL/min × 15 drops/mL = 49.95 drops/min, rounded to 50. Thus, 200 mL/hr and 50 drops/min.

Question 4 of 5
After taking the medication guaifenesin (Mucinex), the client complains of coughing up phlegm. What is the best response by the nurse?
Correct Answer: Guaifenesin is an expectorant that loosens mucus, making coughing up phlegm a normal response. It's not indicative of more pathology, an allergic reaction, or a need for investigation unless symptoms worsen unusually.

A nurse is caring for a client who has deep vein thrombosis. The client has been receiving IV heparin for the past 5 days and now has a new prescription for oral warfarin in addition to the heparin.
