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
D) should only be considered if other interventions, like irrigation, fail to clear the blockage.

Rationale: The correct answer is A: Chest pain radiating to the arm and shortness of breath. These are classic signs of an acute myocardial infarction.
Choice B is incorrect because nausea, vomiting, and high fever are not typical signs of a heart attack.

Rationale: Increasing fiber intake is the most appropriate nursing intervention for a client experiencing constipation. Fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Encouraging the client to remain in bed may exacerbate constipation by reducing movement and promoting inactivity. While stool softeners can be beneficial, they are typically used as a short-term solution and may not address the underlying issue of low fiber intake. Regular exercise is important for overall bowel health; however, in the immediate management of constipation, increasing fiber intake is the most effective intervention.

Rationale: The correct answer is A. High cholesterol and hypertension are significant risk factors for stroke. Regular exercise is an effective way to prevent stroke by managing these risk factors.
Choice B is incorrect as while obesity and smoking are risk factors, preventing stroke through medication and weight loss is not the primary method.
Choice C is incorrect as diabetes and alcohol consumption are risk factors, but preventing stroke through regular checkups is not as direct as managing cholesterol and hypertension.
Choice D is incorrect as lack of exercise and a poor diet are indeed risk factors, but the prevention of stroke through lifestyle changes needs to specifically address high cholesterol and hypertension.
