Nursing Elites

1. A client with dementia is at risk of falling. What is the best intervention to prevent injury?

• A. Place the client in a room close to the nurses' station
• B. Use a bed exit alarm
• C. Encourage family members to stay with the client at all times
• D. Raise all four side rails

Correct answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.

2. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

3. A client has an NG tube that needs irrigation every 8 hours. Which solution should be used to irrigate the tube to maintain fluid and electrolyte balance?

• A. Tap water
• B. Sterile water
• C. 0.9% sodium chloride
• D. 0.45% sodium chloride

Correct answer: C

Rationale: The correct answer is 0.9% sodium chloride. This solution is isotonic and helps maintain electrolyte balance during irrigation, preventing fluid and electrolyte imbalances. Tap water (choice A) may cause electrolyte imbalances due to its hypotonic nature. Sterile water (choice B) is hypotonic and can lead to electrolyte disturbances. 0.45% sodium chloride (choice D) is hypotonic and may also disrupt electrolyte balance when used for irrigation.

4. What is the best nursing intervention for a patient with hyperkalemia?

• A. Administer potassium-wasting diuretics
• B. Encourage a low-potassium diet
• C. Administer potassium supplements
• D. Administer IV fluids

Correct answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

5. A client with type 2 diabetes mellitus is being taught about insulin administration by a nurse. Which of the following instructions should the nurse include?

• A. Inject insulin into the muscle
• B. Rotate injection sites with each dose
• C. Store insulin at room temperature
• D. Massage the injection site after administration

Correct answer: B

Rationale: The correct instruction that the nurse should include is to rotate injection sites with each dose. This practice is essential to prevent tissue damage and ensure proper insulin absorption. Option A is incorrect because insulin should not be injected into the muscle, but rather into the subcutaneous tissue. Option C is incorrect as insulin should be stored in the refrigerator to maintain its effectiveness. Option D is incorrect as massaging the injection site after administration can lead to faster absorption and potentially hypoglycemia.
