What is the most appropriate next step when a client with an NG tube attached to low suctioning becomes nauseated, and the nurse observes a decrease in the flow of gastric secretions?

Correct Answer: B

Rationale: The correct answer is to irrigate the NG tube with sterile water. When a client with an NG tube attached to low suctioning becomes nauseated and there is a decrease in the flow of gastric secretions, it indicates a possible blockage in the tube. Irrigating the tube with sterile water can help clear the blockage, allowing for proper suctioning and relieving the client's nausea. Increasing the suction pressure (Choice A) can further worsen the issue by potentially causing harm to the client. Turning the client on their side (Choice C) may not address the underlying problem of tube blockage. Replacing the NG tube with a new one (Choice D) should only be considered if other interventions, like irrigation, fail to clear the blockage.

Correct Answer: D

Rationale: The correct answer is to replace the NG tube with a new one. When a client with an NG tube experiences nausea and decreased gastric secretions, it indicates a possible problem with the tube itself. Replacing the tube ensures proper functioning and can alleviate the symptoms. Increasing the suction pressure (Choice A) can worsen the client's condition. Turning the client onto their side (Choice B) may be helpful in some situations but does not address the underlying issue. Irrigating the NG tube with sterile water (Choice C) is not the priority and may not resolve the problem.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy. When a client with a tracheostomy is experiencing respiratory distress, the priority intervention is to clear the airway by suctioning the tracheostomy to remove secretions that may be obstructing the air passage. Administering a bronchodilator (Choice A) may be considered if bronchospasm is present, but the immediate focus should be on clearing the airway. Notifying the physician (Choice C) is important but should not delay the immediate intervention of suctioning. Increasing the oxygen flow rate (Choice D) may provide temporary relief, but addressing the root cause of the distress by suctioning is the priority.

Correct Answer: B

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures better stability and support for the client while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice C is incorrect as advancing the cane too far with each step may compromise balance. Choice D is incorrect because advancing the cane and the strong leg together may not provide adequate support for the weaker leg.

Correct Answer: B

Rationale: Irrigating the NG tube with sterile water is the most appropriate strategy for a client with an NG tube experiencing nausea and decreased gastric secretions. This intervention helps in relieving blockages within the tube and can help reduce nausea by ensuring proper drainage. Increasing the suction pressure (Choice A) can lead to complications and should not be done without healthcare provider orders. Turning the client onto their side (Choice C) is a general measure for patient comfort but does not directly address the issue with the NG tube. Replacing the NG tube with a new one (Choice D) is not necessary unless there are specific indications like tube damage or dislodgement.
