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. A nurse is assisting with a presentation at a community center about personal disaster preparedness. Which of the following strategies should the nurse recommend for preparing a home disaster supply kit?

• A. Store enough water for 3 days
• B. Maintain communication with family
• C. Prepare only non-perishable food
• D. Prepare multiple escape routes

Correct answer: A

Rationale: The correct answer is A: 'Store enough water for 3 days.' When preparing a home disaster supply kit, it is crucial to include enough water to last at least 3 days. This is because clean drinking water may not be readily available during a disaster situation. Choice B, 'Maintain communication with family,' is important for coordination but not directly related to preparing a supply kit. Choice C, 'Prepare only non-perishable food,' is also important but does not address the specific recommendation for water. Choice D, 'Prepare multiple escape routes,' is crucial for evacuation planning but does not pertain to the contents of a home disaster supply kit.

3. What is the most important intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Monitor airway patency
• C. Provide bronchodilators
• D. Call for assistance

Correct answer: A

Rationale: Administering oxygen is crucial in managing a patient experiencing respiratory distress. Oxygen therapy helps to improve oxygen levels in the blood, supporting vital organ functions. While monitoring airway patency is important, administering oxygen takes precedence in ensuring the patient receives an adequate oxygen supply. Providing bronchodilators may be beneficial in certain respiratory conditions, but the immediate priority in distress is to address oxygenation. Calling for assistance is essential, but the immediate intervention to support the patient's respiratory function is administering oxygen.

4. A nurse is reinforcing teaching about using a cane with a client who has left-leg weakness. What instruction should the nurse give?

• A. Use the cane on the weaker side
• B. Advance the cane and the strong leg together
• C. Maintain two points of support on the floor at all times
• D. Advance the cane 30 to 45 cm with each step

Correct answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

5. What are the key signs of hyperglycemia?

• A. Increased thirst and frequent urination
• B. Decreased appetite and low blood pressure
• C. Weight loss and nausea
• D. Increased sweating and confusion

Correct answer: A

Rationale: The correct answer is A: Increased thirst and frequent urination. These are classic signs of hyperglycemia, indicating elevated blood sugar levels. Choice B is incorrect as hyperglycemia usually presents with increased appetite rather than decreased appetite and low blood pressure. Choice C is incorrect as weight loss is more commonly associated with uncontrolled diabetes rather than hyperglycemia. Choice D is incorrect as increased sweating and confusion are not typical signs of hyperglycemia.
