AEMT IV Therapy and Fluid Administration 3

Question 1

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?

Accepted Answer

167 gtt/min

Answer

Drip rate = (Volume × drop factor) / time = (1,000 × 10) / 60 = 167 gtt/min.

Question 2

Which of the following best describes a hypertonic solution?

Accepted Answer

A solution with higher osmolality than plasma that draws fluid into the vascular space

Answer

Hypertonic solutions have osmolality greater than plasma and draw water from interstitial and intracellular spaces into the vascular compartment.

Question 3

Air embolism is a potentially fatal complication of IV therapy. To prevent it, you should:

Accepted Answer

Prime the IV tubing to remove all air before connecting to the catheter

Answer

Priming (flushing air out of) the IV tubing before connecting it to the patient prevents air from entering the venous system.

Question 4

In a patient with suspected traumatic brain injury (TBI), which IV fluid is MOST appropriate?

Accepted Answer

Isotonic saline (0.9% NS) or LR, avoiding hypotonic solutions

Answer

Hypotonic fluids lower plasma osmolality and worsen cerebral edema in TBI; isotonic crystalloids are used to maintain perfusion without increasing brain swelling.

Question 5

A patient develops redness, pain, and warmth tracking up the arm from the IV site. This is MOST consistent with:

Accepted Answer

Phlebitis or early cellulitis

Answer

Red streaking with warmth and tenderness traveling proximally from an IV site indicates phlebitis (vein inflammation) or early cellulitis.
