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. Which of the following findings should the nurse anticipate in the medical record of a client with a pressure ulcer?

• A. Serum albumin level of 3 g/dL
• B. Braden scale score of 20
• C. Norton scale score of 18
• D. Hemoglobin level of 13 g/dL

Correct answer: A

Rationale: The correct answer is A: Serum albumin level of 3 g/dL. A serum albumin level of 3 g/dL indicates poor nutrition, which is commonly seen in clients with pressure ulcers. Choice B, a Braden scale score of 20, is incorrect because a higher Braden scale score indicates a lower risk of developing pressure ulcers. Choice C, a Norton scale score of 18, is incorrect as it is a tool used to assess the risk of developing pressure ulcers, not a finding in a client with an existing pressure ulcer. Choice D, a hemoglobin level of 13 g/dL, is unrelated to pressure ulcers and does not directly reflect the nutritional status associated with this condition.

3. A nurse is reinforcing teaching about food selection with a client who has a moderate burn injury. Which of the following foods should the nurse recommend as being high in vitamin C?

• A. Tomatoes
• B. Carrots
• C. Avocados
• D. Apricots

Correct answer: A

Rationale: Tomatoes are high in vitamin C, which is crucial for wound healing, making them an excellent recommendation for a client with a burn injury. Carrots, avocados, and apricots are not as rich in vitamin C compared to tomatoes, and therefore, they are not the best choice for promoting healing in this scenario.

4. A client is having difficulty voiding after removal of an indwelling urinary catheter. What should the nurse do?

• A. Assess for bladder distention after 6 hours
• B. Encourage the client to use a bedpan in the supine position
• C. Restrict the client's intake of oral fluids
• D. Pour warm water over the client's perineum

Correct answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This action helps stimulate voiding post-catheterization by promoting relaxation and providing sensory input. Assessing for bladder distention after 6 hours (Choice A) is important but not the immediate intervention needed for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not effectively address the issue of post-catheterization voiding difficulty. Restricting the client's intake of oral fluids (Choice C) is not appropriate and can lead to dehydration, which is not helpful in promoting voiding.

5. A nurse is reviewing the plan of care for a client who is receiving oxygen therapy. Which of the following interventions should the nurse include to prevent complications?

• A. Check the client's oxygen saturation every 2 hours
• B. Provide humidified oxygen
• C. Instruct the client to perform deep breathing exercises
• D. Use an oxygen mask for delivery

Correct answer: B

Rationale: The correct answer is B: Provide humidified oxygen. Providing humidified oxygen helps prevent dryness and irritation of the respiratory tract during oxygen therapy. This intervention is crucial in preventing complications such as mucous membrane dryness and potential damage to the airways. Checking the client's oxygen saturation every 2 hours (choice A) is essential for monitoring the client's response to therapy but does not directly prevent complications. Instructing the client to perform deep breathing exercises (choice C) is beneficial for respiratory function but does not directly address preventing complications related to oxygen therapy. Using an oxygen mask for delivery (choice D) is a common method of administering oxygen but does not specifically focus on preventing complications like dryness and irritation.
