When calculating a drip rate using a macro-drip IV set (10 gtt/mL), what is the drip rate for 1,000 mL to be infused over 60 minutes?
Answer: 167 gtt/min
Drip rate = (Volume × drop factor) / time = (1,000 × 10) / 60 = 167 gtt/min.
Which of the following best describes a hypertonic solution?
Answer: A solution with higher osmolality than plasma that draws fluid into the vascular space
Hypertonic solutions have osmolality greater than plasma and draw water from interstitial and intracellular spaces into the vascular compartment.
Air embolism is a potentially fatal complication of IV therapy. To prevent it, you should:
Answer: Prime the IV tubing to remove all air before connecting to the catheter
Priming (flushing air out of) the IV tubing before connecting it to the patient prevents air from entering the venous system.
In a patient with suspected traumatic brain injury (TBI), which IV fluid is MOST appropriate?
Answer: Isotonic saline (0.9% NS) or LR, avoiding hypotonic solutions
Hypotonic fluids lower plasma osmolality and worsen cerebral edema in TBI; isotonic crystalloids are used to maintain perfusion without increasing brain swelling.
A patient develops redness, pain, and warmth tracking up the arm from the IV site. This is MOST consistent with:
Answer: Phlebitis or early cellulitis
Red streaking with warmth and tenderness traveling proximally from an IV site indicates phlebitis (vein inflammation) or early cellulitis.
You are ordered to administer 250 mg of a drug dissolved in 100 mL NS over 30 minutes using a 60 gtt/mL microdrip set. What is the drip rate?
Answer: 200 gtt/min
(100 mL × 60 gtt/mL) / 30 min = 200 gtt/min.
