1. A client is to receive a transfusion of packed RBCs. Which of the following actions should the nurse take?

• A. Prime IV tubing with 0.9% sodium chloride
• B. Use a 24-gauge IV catheter
• C. Obtain filterless IV tubing
• D. Place blood in the warmer for 1 hr

Correct answer: A

Rationale: Prior to administering a blood transfusion, it is essential to prime the IV tubing with 0.9% sodium chloride to prevent hemolysis of the blood cells. Using a smaller gauge IV catheter (e.g., 20 or 22 gauge) is recommended for blood transfusions to prevent hemolysis. Filterless IV tubing is contraindicated for blood transfusions as it does not have a filter to trap potential blood clots or debris. Warming blood is unnecessary and could lead to the development of bacteria in the blood product. Therefore, the correct action for the nurse to take is to prime the IV tubing with 0.9% sodium chloride.

2. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.

3. When preparing to administer an IM injection that is irritating to the subcutaneous tissue, what is the best action to prevent tracking of the medication?

• A. Use a small gauge needle
• B. Apply ice on the injection site
• C. Administer at a 45° angle
• D. Use the Z-track technique

Correct answer: D

Rationale: The Z-track technique is the best action to prevent tracking of the medication when administering an IM injection that is irritating to the subcutaneous tissue. This technique involves pulling the skin to the side before administering the injection and then releasing the skin after the injection. By doing so, a zig-zag pathway is created, preventing the medication from leaking into the subcutaneous tissue and reducing irritation. Options A, B, and C are incorrect. Using a small gauge needle may not prevent tracking of the medication. Applying ice on the injection site or administering at a 45° angle does not specifically address preventing tracking of the medication in cases where the injection is irritating to the subcutaneous tissue.

4. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

5. A healthcare professional is assessing a client who has experienced a left-hemispheric stroke. Which of the following is an expected finding?

• A. Impulse control difficulty
• B. Poor judgement
• C. Inability to recognize familiar objects
• D. Loss of depth perception

Correct answer: C

Rationale: Patients who have experienced a left-hemispheric stroke may exhibit symptoms of agnosia, which is the inability to recognize familiar objects or people. This occurs due to damage to the right hemisphere of the brain, which is responsible for visual and spatial perception. Impulse control difficulty, poor judgment, and loss of depth perception are not typically associated with left-hemispheric strokes.
