Nursing Elites

1. 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.

2. 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.

3. A nurse is reinforcing home safety instructions with the parent of a newborn. Which of the following statements should the nurse include in the instructions?

• A. Place your baby's crib away from heat vents
• B. Place the crib close to a heater
• C. Place the crib near a window
• D. Place soft toys in the crib

Correct answer: A

Rationale: The correct answer is A: 'Place your baby's crib away from heat vents.' Placing the crib away from heat vents is essential to prevent the baby from becoming overheated and to reduce the risk of Sudden Infant Death Syndrome (SIDS). Choice B is incorrect because placing the crib close to a heater increases the risk of overheating and poses a fire hazard. Choice C is incorrect as placing the crib near a window exposes the baby to drafts and temperature fluctuations. Choice D is incorrect as soft toys in the crib can pose a suffocation risk to the newborn.

4. What is the first intervention for a patient in shock?

• A. Administer fluids
• B. Monitor blood pressure
• C. Provide oxygen
• D. Call for assistance

Correct answer: A

Rationale: The correct answer is to administer fluids. In a patient experiencing shock, the priority is to address inadequate perfusion by restoring circulating blood volume. Administering fluids helps improve perfusion and oxygen delivery to vital organs. Monitoring blood pressure, providing oxygen, and calling for assistance are important steps but administering fluids is the initial and most critical intervention in the management of shock.

5. What is the initial step a nurse should take when irrigating a wound?

• A. Wear sterile gloves while removing the old dressing
• B. Cleanse the wound from the center outward
• C. Apply a warm compress to the wound
• D. Use a 20 mL syringe to irrigate the wound

Correct answer: B

Rationale: The correct first action when irrigating a wound is to cleanse the wound from the center outward. This method helps remove debris and pathogens effectively, reducing the risk of infection. Choice A is incorrect because wearing sterile gloves should be done before starting the wound irrigation but is not the first action in the process. Choice C is incorrect as applying a warm compress is not the initial step in wound irrigation. Choice D is also incorrect as using a syringe to irrigate the wound comes after cleansing the wound.
