Nursing Elites

1. What is the appropriate needle size for insulin injection?

• A. 18G, 1 ½” long
• B. 22G, 1” long
• C. 22G, 1 ½” long
• D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.

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. A client is being instructed on how to perform pursed-lip breathing. Which of the following should be included in the plan of care?

• A. Take quick breaths upon inhalation.
• B. Place your hand over your stomach.
• C. Take a deep breath in through your nose.
• D. Puff your cheeks upon exhalation.

Correct answer: C

Rationale: Pursed-lip breathing is a breathing technique that involves inhaling slowly through the nose and exhaling gently through pursed lips. This technique helps improve breathing efficiency and can be beneficial for individuals with respiratory conditions. Instructing the client to take a deep breath in through the nose is essential for proper execution of pursed-lip breathing, making choice C the correct answer.

4. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

5. 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.
