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 is an early sign that suctioning is required for a client with a tracheostomy?

• A. Bradycardia
• B. Irritability
• C. Confusion
• D. Hypotension

Correct answer: B

Rationale: Irritability is an early sign that suctioning is necessary to clear the airway in a client with a tracheostomy. When secretions build up in the tracheostomy tube, the client may become irritable due to the discomfort and the compromised airway. Bradycardia, confusion, and hypotension are not typically early signs that suctioning is required. Bradycardia may occur if the airway becomes severely compromised, confusion may be a late sign of hypoxia, and hypotension is not directly related to the need for suctioning in a client with a tracheostomy.

3. A charge nurse is teaching new staff members about factors that increase a client's risk of becoming violent. Which of the following risk factors should the nurse include as the best predictor of future violence?

• A. Experiencing delusions.
• B. Male gender.
• C. Previous violent behavior.
• D. A history of being in prison.

Correct answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.

4. A nurse is planning to irrigate and dress a clean, granulating wound for a client. Which of the following actions should the nurse take?

• A. Irrigate the wound with normal saline.
• B. Apply a wet-to-dry gauze dressing.
• C. Use a cotton ball to cleanse the wound.
• D. Administer an analgesic after the dressing change.

Correct answer: A

Rationale: The correct answer is to irrigate the wound with normal saline. Normal saline is the preferred solution for wound irrigation as it is isotonic and gentle, promoting healing in granulating wounds. Choice B, applying a wet-to-dry gauze dressing, is not appropriate for clean, granulating wounds as it can cause trauma to the wound bed upon removal. Choice C, using a cotton ball to cleanse the wound, is not ideal as cotton fibers can adhere to the wound and cause contamination. Choice D, administering an analgesic after the dressing change, is important for pain management but is not directly related to irrigating and dressing the wound.

5. A nurse is reviewing the plan of care for a client who is postoperative following a hip replacement. Which of the following interventions should the nurse implement to prevent venous thromboembolism?

• A. Instruct the client to perform ankle pumps
• B. Administer anticoagulant therapy as prescribed
• C. Maintain the client in a prone position
• D. Encourage the client to ambulate as tolerated

Correct answer: B

Rationale: The correct intervention to prevent venous thromboembolism in a postoperative client following hip replacement is to administer anticoagulant therapy as prescribed. Anticoagulants help prevent blood clots from forming. Instructing the client to perform ankle pumps helps prevent blood clots by promoting circulation. Maintaining the client in a prone position can increase the risk of venous stasis and thrombus formation. Encouraging the client to ambulate as tolerated also helps prevent venous thromboembolism by promoting blood flow and preventing stasis.
