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: The correct answer is to instruct the client to step up with the unaffected leg first. This action is crucial as it ensures proper balance and safety when ascending stairs with crutches. By stepping up with the unaffected leg first, the client can maintain stability and reduce the risk of falls. Choices A, C, and D are incorrect. Moving both crutches up first (Choice A) may lead to imbalance and difficulty in weight distribution. Leaning forward on the crutches before stepping up (Choice C) can compromise the client's stability and increase the risk of falling. While holding onto the handrail for support (Choice D) is important, stepping up with the unaffected leg first takes precedence to establish a secure and safe movement up the stairs.

Correct Answer: A

Rationale: The correct procedure for inserting a nasogastric (NG) tube involves measuring the tube to ensure the appropriate length for insertion and using lubrication to reduce discomfort and aid in smooth insertion. Choice B is incorrect as measuring the tube is essential for proper placement. Choice C is incorrect as lubrication helps in easing the insertion process. Choice D is incorrect as checking the placement comes after insertion and should not be done simultaneously with the insertion process.

Correct Answer: C

Rationale: The correct response is C: 'It includes end-of-life care instructions.' An advance directive is a legal document that outlines a client's preferences for medical treatment and end-of-life care in case they are unable to communicate. Choice A is incorrect because an advance directive focuses on healthcare decisions, not funeral arrangements. Choice B is incorrect as organ donation is a separate process from advance directives. Choice D is incorrect as advance directives do not provide legal guardianship rights, but rather specify healthcare wishes.
