Nursing Elites

1. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?

• A. Hydrostatic pressure
• B. Osmosis and osmolality
• C. Diffusion
• D. Active transport

Correct answer: B

Rationale:

2. Place a washcloth between the skin and tourniquet

• A. Provide a bed bath instead of letting the client take a shower
• B. Use sterile technique when changing the dressing.
• C. Disconnect the intravenous fluid tubing prior to the clients bath.
• D. Use a plastic bag to cover the extremity with the device

Correct answer: D

Rationale:

3. A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?

• A. Furosemide (Lasix) 40 mg intravenous push
• B. Sodium bicarbonate 100 mEq diluted in 1 L of D5W
• C. Mechanical ventilation
• D. Indwelling urinary catheter

Correct answer: B

Rationale:

4. A nurse assesses a client who is experiencing an acid-base imbalance. The clients arterial blood gas values are pH 7.34, PaO2 88 mm Hg, PaCO2 38 mm Hg, and HCO3 19 mEq/L. Which assessment should the nurse perform first?

• A. . Cardiac rate and rhythm
• B. Skin and mucous membranes
• C. Musculoskeletal strength
• D. Level of orientation

Correct answer: A

Rationale:

5. While assessing a patient's peripheral IV site, you note edema around the insertion site. How should you document this complication related to IV therapy?

• A. Air emboli
• B. Phlebitis
• C. Infiltration
• D. Fluid overload

Correct answer: C

Rationale: Infiltration is the administration of a nonvesicant solution or medication into the surrounding tissue, typically due to the dislodgement or perforation of the vein wall by the IV cannula. It is characterized by edema around the insertion site, leakage of IV fluid, discomfort, coolness, and a decrease in flow rate. In this scenario, the presence of edema indicates infiltration, not air emboli, phlebitis, or fluid overload. Air emboli refer to air bubbles in the bloodstream, phlebitis is inflammation of the vein, and fluid overload is an excessive volume of fluid in the circulatory system.
