IV Therapy Questions and Answers

1.

The goals of IV therapy include all of the following except
- A.
  
  Restore acid-base balance
- B.
  
  Maintain or replace fluids, electrolytes, vitamins, proteins, fats, and calories in patients who can not maintain adequate intake by mouth.
- C.
  
  Restore volumes of blood components
- D.
  
  Administer safe and effective infusions of medicines by using the appropriate arterial access
- E.
  
  Provide nutrition by resting the gastrointestinal tract.
Correct Answer
D. Administer safe and effective infusions of medicines by using the appropriate arterial access

Explanation
The goals of IV therapy include restoring acid-base balance, maintaining or replacing fluids, electrolytes, vitamins, proteins, fats, and calories in patients who cannot maintain adequate intake by mouth, restoring volumes of blood components, and Providing nutrition by resting the gastrointestinal tract. Administering safe and effective infusions of medicines by using the appropriate arterial access is not one of the goals of IV therapy.

The extracellular compartment contains about how much of the body’s weight?
- A.
  
  20%
- B.
  
  30%
- C.
  
  40%
- D.
  
  50%
Correct Answer
A. 20%

Explanation
The extracellular compartment refers to the fluid that is present outside the cells in the body. This includes the fluid in the blood vessels (plasma) and the fluid between the cells (interstitial fluid). The correct answer of 20% suggests that approximately one-fifth of the total body weight is present in the extracellular compartment.

What is the compartment within the spaces between the cells that are outside of the vascular compartment called?
- A.
  
  Interstitial compartment
- B.
  
  Intravascular compartment
- C.
  
  Extracellular compartment
- D.
  
  None of these
Correct Answer
A. Interstitial compartment

Explanation
The space between and around bodily tissue is called the interstitial compartment. It refers to the fluid-filled spaces surrounding cells where interstitial fluid exists. Interstitial fluid provides a medium for the exchange of nutrients, gases, and waste products between the cells and the blood vessels in the surrounding tissues. It also contains the lymphatic system.

What are solutions that have fewer dissolved particles than the blood are called?
- A.
  
  Isotonic solution
- B.
  
  Osmotic solution
- C.
  
  Hypertonic solution
- D.
  
  Hypotonic solution
Correct Answer
D. Hypotonic solution

Explanation
A hypotonic solution is a solution that has a low solute and higher water concentration than the blood. In this solution, water moves into the cells through osmosis, causing them to swell or burst. Sometimes, a slightly hypotonic solution like 0.45% sodium chloride may be used to rehydrate the cells.

All of the following are signs and symptoms of water excess or deficit except...
- A.
  
  Muscle twitching
- B.
  
  Coma
- C.
  
  Tachycardia
- D.
  
  Oliguria
- E.
  
  Mild decrease in temperature
Correct Answer
E. Mild decrease in temperature

Explanation
A mild decrease in temperature is not a sign or symptom of water excess or deficit. Water excess or deficit can lead to various symptoms such as muscle twitching, coma, tachycardia (rapid heart rate), and oliguria (decreased urine output). However, a mild decrease in temperature is not typically associated with water imbalance.

What are the three types of IV fluids?
- A.
  
  Isotonic
- B.
  
  Hypotonic
- C.
  
  Hypertonic
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above.” Isotonic fluids have the same concentration of solutes as blood, hypotonic fluids have a lower concentration of solutes, and hypertonic fluids have a higher concentration of solutes than blood. Therefore, all three types of fluids play different roles in maintaining the balance of fluids and electrolytes in the body.

By explaining the procedure, the patient can also provide informed consent, which is essential in any medical intervention. Additionally, explaining the procedure helps to establish trust and rapport between the healthcare provider and the patient, creating a more comfortable and cooperative environment for the venipuncture.

Correct Answer
B. To increase blood supply to the area

Explanation
The rationale for having the patient open and close their fist several times is to increase blood supply to the area. This repetitive movement helps to stimulate blood flow and circulation, which can be beneficial for drawing blood.

  3 days
- B.
  
  4 days
- C.
  
  5 days

The standard dwell time for a catheter is typically 3 days or less. This means that the catheter should be left in place for a maximum of 3 days before it needs to be replaced or removed. Keeping the catheter in place for longer periods increases the risk of infection and other complications. Therefore, it is important to adhere to the recommended dwell time to ensure patient safety and minimize potential complications.
