Correct Answer: B

Rationale: The correct answer is B because the client should press the button when feeling fetal movement to track the baby's activity. Choice A is incorrect because the client should press the button during movements. Choice C is incorrect as the button should be pressed during fetal movements, not contractions. Choice D is irrelevant to the instructions for the nonstress test.

Correct Answer: A

Rationale: Encouraging oral fluid intake is a crucial nursing intervention in managing a patient with fluid volume deficit. By encouraging oral fluid intake, the patient can increase hydration levels, helping to correct the deficit. Administering IV fluids may be necessary in severe cases or when the patient is unable to tolerate oral intake. Monitoring urine output and checking electrolyte levels are essential aspects of assessing fluid volume status, but they are not direct interventions for correcting fluid volume deficit. Monitoring skin turgor and capillary refill are important assessments for fluid volume status but are not direct management strategies.

Correct Answer: C

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.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps improve oxygenation by preventing airway collapse, slowing down the breathing rate, and promoting better gas exchange. Administering oxygen at 2L/min via nasal cannula is not the first-line intervention as it can cause oxygen toxicity in COPD patients. Positioning the client in high Fowler's position may improve ventilation but does not specifically address the breathing technique required for COPD. Encouraging deep breathing and coughing is generally not recommended for clients with COPD as it can lead to air trapping and increased work of breathing.

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.
