Correct Answer: D

Rationale: The correct intervention for the nurse to include in the plan of care for a client undergoing total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. Changing the tubing at regular intervals helps reduce the risk of infection associated with central venous catheters. Monitoring electrolyte levels daily (Choice A) is important but not specific to TPN. Weighing the client daily (Choice B) is important for monitoring fluid status but not directly related to TPN. Monitoring blood glucose levels every 6 hours (Choice C) is essential for clients receiving TPN, but changing the tubing is a more critical intervention to prevent infections.

Correct Answer: A

Rationale: The correct answer is to insert a chest tube. In managing a patient with a suspected pneumothorax, the priority is to relieve the pressure from the pneumothorax by inserting a chest tube. Monitoring respiratory status (choice B) is important but comes after ensuring proper management of the pneumothorax. Administering oxygen (choice C) can help support oxygenation but does not address the underlying issue of pressure in the thoracic cavity. Calling for assistance (choice D) can be done concurrently with managing the pneumothorax, but the immediate intervention to address the pneumothorax itself is chest tube insertion.

Correct Answer: B

Rationale: The correct answer is to ensure oxygen tanks are kept upright at all times. This is important to prevent the tanks from falling over, which can lead to injuries or tank damage. Choice A is incorrect because oxygen tanks should not be stored in a closet when not in use, as this can lead to poor ventilation and potential hazards. Choice C is incorrect because smoking near oxygen tanks poses a significant fire risk. Choice D is incorrect because while it is important to keep oxygen equipment away from heat sources, ensuring the tanks are kept upright is a more critical safety measure.

Correct Answer: B

Rationale: Performing a wound culture before applying antibiotics is crucial to identify the specific pathogen causing the infection. This helps in selecting the most effective antibiotics for treatment. Changing the wound dressing, applying a wet-to-dry dressing, or cleansing the wound are important interventions but should follow the assessment and identification of the infecting organism through a wound culture to guide appropriate treatment.

Correct Answer: A

Rationale: Using a bed exit alarm system is crucial in minimizing the risk of injury for a client with dementia. This intervention helps alert staff when the client is attempting to leave the bed, reducing the chances of falls. Raising all four side rails while the client is in bed (Choice B) can lead to restraint-related issues and is not recommended unless necessary for safety reasons. Applying a soft wrist restraint (Choice C) is generally not the first choice in managing clients with dementia due to the risk of complications and loss of mobility. Dimming the lights in the client's room (Choice D) may not directly address the risk of injury associated with dementia and may even increase the risk of falls due to poor visibility.
