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 caring for a client who is 1 day postoperative and is unable to ambulate. Which of the following actions should the nurse take to promote the client's venous return?

• A. Encourage deep breathing exercises
• B. Maintain the client in a supine position
• C. Apply a sequential compression device
• D. Massage the client's legs

Correct answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.

3. What are the complications of untreated deep vein thrombosis (DVT)?

• A. Pulmonary embolism and stroke
• B. Kidney failure and hypertension
• C. Liver failure and electrolyte imbalance
• D. Fluid overload and bradycardia

Correct answer: A

Rationale: Corrected Rationale: Untreated DVT can lead to complications such as pulmonary embolism and stroke. Pulmonary embolism occurs when a blood clot from the leg travels to the lungs, potentially blocking blood flow and causing respiratory distress. Stroke can occur if a blood clot dislodges from the leg veins, travels to the brain, and obstructs a blood vessel, leading to brain tissue damage. Both of these complications are life-threatening if not managed promptly. The other choices (B, C, D) do not represent common complications of untreated DVT and are therefore incorrect.

4. A nurse is providing discharge instructions to a client who has a prescription for the use of oxygen in his home. Which of the following should the nurse teach the client about using oxygen safely in his home?

• A. Family members who smoke should be at least 10 ft away from the client when oxygen is in use
• B. Nail polish should not be used near a client who is receiving oxygen
• C. A 'No Smoking' sign should be placed on the front door
• D. Cotton bedding and clothing should be replaced with items made from wool

Correct answer: C

Rationale: The correct answer is C. Placing a 'No Smoking' sign on the front door is crucial for fire safety when using oxygen at home. Choice A is incorrect as family members who smoke should not be around the client when oxygen is in use, not just at a distance. Choice B is not directly related to oxygen safety. Choice D is also irrelevant as the type of bedding and clothing material does not impact oxygen safety.

5. A nurse is reinforcing teaching about ways to reduce solid fat consumption with a client who has an elevated cholesterol level. Which of the following instructions should the nurse include?

• A. Use oils with trans fats
• B. Choose lean cuts of beef
• C. Avoid purchasing beef that is a loin cut
• D. Purchase chicken instead of lamb

Correct answer: B

Rationale: The correct answer is B: 'Choose lean cuts of beef.' Selecting lean cuts of beef is crucial in reducing solid fat consumption for individuals with high cholesterol levels. Lean cuts contain less saturated fat compared to fatty cuts, thus aiding in managing cholesterol levels. Option A is incorrect as oils with trans fats should be avoided since they contribute to unhealthy fats. Option C is not directly related to reducing solid fat consumption. Option D, while suggesting a leaner meat option, does not address the issue of solid fat consumption as directly as choosing lean cuts of beef.
