1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. Which of the following indicates a hazard for a client on oxygen therapy?

• A. A 'No Smoking' sign is on the door.
• B. The client is wearing a synthetic gown.
• C. Electrical equipment is grounded.
• D. Matches are removed.

Correct answer: B

Rationale: The correct answer is that the client is wearing a synthetic gown. A synthetic gown might generate sparks of static electricity, which can be a fire hazard, especially in the presence of oxygen. Clients on oxygen therapy should wear cotton gowns to minimize the risk of fire. The other options are not hazards for a client on oxygen therapy: having a 'No Smoking' sign on the door promotes safety by preventing smoking, ensuring electrical equipment is grounded reduces the risk of electrical hazards, and removing matches decreases the risk of fire hazards.

3. After assigning tasks, what is the nurse's primary responsibility?

• A. Assigning any tasks that were not completed to the next nursing shift
• B. Documenting completion of each task
• C. Allowing each staff member to make judgments when performing the tasks
• D. Following up with each staff member regarding the performance of the task and the outcomes related to implementation of the task

Correct answer: D

Rationale: The nurse's primary responsibility after assigning tasks is to follow up with each staff member regarding the task's performance and outcomes. This ensures accountability and quality care delivery. Allowing staff members to make judgments independently can compromise patient safety if they lack the necessary knowledge or experience. While documenting task completion is important, it should follow the follow-up to assess outcomes. Assigning incomplete tasks to the next shift is not ideal as it may result in unmet patient needs and increased workload for the next shift.

4. A nurse is performing suctioning through an adult client's tracheostomy tube. The nurse notes that the client's oxygen saturation is 89% and terminates the procedure. Which action would the nurse take next?

• A. Rechecking the pulse oximetry reading
• B. Calling the respiratory therapist
• C. Calling the healthcare provider
• D. Oxygenating the client with 100% oxygen

Correct answer: D

Rationale: The nurse should monitor the client's heart rate and pulse oximetry during suctioning to assess the client's tolerance of the procedure. Oxygen desaturation to below 90% indicates hypoxemia. If hypoxia occurs during suctioning, the nurse must terminate the procedure and oxygenate the client with 100% oxygen to address the hypoxemia promptly and ensure the client's safety. Rechecking the pulse oximetry reading is important, but the priority is to address the hypoxemia by providing oxygen. Contacting the healthcare provider or respiratory therapist is not necessary at this time as the nurse can manage the hypoxemia with oxygenation. Oxygenating the client with 100% oxygen is the immediate action required in this situation.

5. A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?

• A. Submerge the end of the chest tube in a bottle of sterile water
• B. Clamp the chest tube with a Kelly clamp
• C. Call the health care provider
• D. Instruct the client to inhale and hold his breath

Correct answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.
