Hypotonic, Hypertonic, & Isotonic IV Solution Quiz for Nursing Students & NCLEX Exam

This fluid & electrolyte quiz is designed to test your knowledge on hypotonic, hypertonic, and isotonic solutions. In addition, you will be quizzed on your ability to understand how osmosis works in these type of osmolarity conditions.

In many of your nursing school classes and for the NCLEX exam, you will have to know how hypotonic, hypertonic, and isotonic solutions work on the cell and the nursing interventions when administrating these type of fluids.

Quiz on Isotonic, Hypotonic, & Hypertonic Solutions

1. When the cell presents with the same concentration on the inside and outside with no shifting of fluids this is called?
A. Hypotonic
B. Hypertonic
C. Isotonic
D. Osmosis
The answer is C: Isotonic

2. Which of the following is not a hypertonic fluid?
A. 3% Saline
B. D5W
C. 10% Dextrose in Water (D10W)
D. 5% Dextrose in Lactated Ringer’s
The answer is B: D5W

3. What type of fluid would a patient with severe hyponatremia most likely be started on?
A. Hypotonic
B. Hypertonic
C. Isotonic
D. Colloid
The answer is B: Hypertonic

4. When administering a hypertonic solution the nurse should closely watch for?
A. Signs of dehydration
B. Pulmonary Edema
C. Fluid volume deficient
D. Increased Lactate level
The answer is B: Pulmonary Edema

5. A patient with cerebral edema would most likely be order what type of solution?
A. 3% Saline
B. 0.9% Normal Saline
C. Lactated Ringer’s
D. 0.225% Normal Saline
The answer is A: 3% Saline. A patient with cerebral edema would be ordered a HYPERTONIC solution to decrease brain swelling. The solution would remove water from the brain cells back into the intravascular system to be excreted. 3% Saline is the only hypertonic option.

6. _______ solutions cause cell dehydration and help increase fluid in the extracellular space.
A. Hypotonic
B. Osmosis
C. Isotonic
D. Hypertonic
The answer is D: Hypertonic

7. D5W solutions are sometimes considered a hypotonic solution as well as an isotonic solution because after the body metabolizes the dextrose the solution acts as a hypotonic solution.
True
False
The answer is TRUE. D5W is classified as a ISOTONIC fluid BUT after adminstration the body metabolizes the dextrose and the fluid left over is a hypotonic solution.

8. Which solution below is NOT a hypertonic solution?
A. 5% Dextrose in 0.9% Saline
B. 5% Saline
C. 5% Dextrose in Lactated Ringer’s
D. 0.33% saline (1/3 NS)
The answer is D: 0.33% saline (1/3 NS)

9. Which patient below would NOT be a candidate for a hypotonic solution?
A. Patient with increased intracranial pressure
B. Patient with Diabetic Ketoacidosis
C. Patient experiencing Hyperosmolar Hyperglycemia
D. All of the options are correct
The answer is A: Patient with increased intracranial pressure

10. Which condition below could lead to cell lysis, if not properly monitored?
A. Isotonicity
B. Hypertonicity
C. Hypotonicity
D. None of the options are correct
The answer is C: Hypotonicity

11. ________ fluids remove water from the extracellular space into the intracellular space.
A. Hypotonic
B. Hypertonic
C. Isotonic
D. Colloids
The answer is A: Hypotonic

12. Isotonic fluids cause shifting of water from the extracellular space to the intracellular space.
True
False
The answer is FALSE. HYPOTONIC fluids cause shifting of water from the extracellular space to the intracellular space (not isotonic)

13. A patient is being admitted with dehydration due to nausea and vomiting. Which fluid would you expect the patient to be started on?
A. 5% Dextrose in 0.9% Saline
B. 0.33% saline
C. 0.225% saline
D. 0.9% Normal Saline
The answer is D: 0.9% Normal Saline

14. The doctor orders an isotonic fluid for a patient. Which of the following is not an isotonic fluid?
A. 0.9% Normal Saline
B. Lactated Ringer’s
C. 0.45% Saline
D. 5% Dextrose in 0.225% saline
The answer is C: 0.45% Saline
