Correct Answer: C

Rationale: Encouraging the client to use a stool softener is the appropriate intervention for constipation. Stool softeners help to soften the stool, making it easier to pass and relieving constipation without straining the client. Monitoring bowel sounds (Choice A) may be relevant for other gastrointestinal issues but is not specifically indicated for constipation. Increasing activity (Choice B) can be helpful in some cases, but it is not the first-line intervention for constipation. Encouraging bed rest (Choice D) can worsen constipation by reducing mobility and promoting inactivity.

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: 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.

Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. In SIADH, there is excessive release of antidiuretic hormone, causing water retention and dilutional hyponatremia. Polyuria (choice A) is increased urination, which is not a typical finding in SIADH. Dehydration (choice B) is the loss of body fluids, which is opposite to the fluid retention seen in SIADH. Hyperglycemia (choice D) is elevated blood sugar levels and is not directly related to SIADH.

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.
