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 will you administer and how many drops per minute?
Correct Answer: C
Rationale: Rate: 1000 mL / 5 hr = 200 mL/hr. Drops/min: (1000 mL × 15 drops/mL) / (5 × 60 min) = 50 drops/min.
Question 2 of 5
A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
Correct Answer: A
Rationale: Using the formula (volume × drop factor) / time in minutes: (1000 mL × 10 gtt/mL) / 360 min = 27.78 gtt/min, rounded to 28 gtt/min.
Question 3 of 5
The nurse is teaching a client about digestion. Which statement reflects that the client understands the teaching?
Correct Answer: D
Rationale: Digestion is the breakdown of food into absorbable molecules, as correctly stated. Other options describe unrelated processes.
Question 4 of 5
What are the risk factors associated with peptic ulcer disease?
Correct Answer: A,D,E
Rationale: Family history, smoking, and excessive caffeine increase peptic ulcer risk. Blood type A is not a risk factor, and acetaminophen is safer than NSAIDs.
Question 5 of 5
Which type of laxative causes peristalsis by irritating the bowel?
Correct Answer: C
Rationale: Stimulant laxatives, like bisacodyl, irritate the bowel lining to stimulate peristalsis, promoting bowel movements. Stool softeners moisten stool, saline/osmotic laxatives draw water into the intestines, and bulk-forming laxatives increase stool bulk without irritation.
