A nurse is caring for a client with an NG tube who reports nausea and a decrease in gastric secretions. What is the nurse's next step?

Correct Answer: B

Rationale: The correct next step for the nurse is to irrigate the NG tube with sterile water. This action helps relieve blockages that may be causing the symptoms of nausea and decreased gastric secretions. Administering an antiemetic (Choice A) may mask the underlying issue without addressing the possible blockage. Increasing the suction setting (Choice C) is not indicated without first addressing the potential blockage. Replacing the NG tube (Choice D) is also premature before attempting to clear any obstructions.

Correct Answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, which should be limited in clients with heart failure to prevent electrolyte imbalances. While leafy green vegetables and whole grains are generally healthy options, they are not typically restricted in heart failure patients. Potatoes, although they contain potassium, are not as high in potassium as bananas and are not usually restricted as strictly.

Correct Answer: C

Rationale: The correct method for teaching a client to use a cane when they have left-leg weakness is to maintain two points of support on the floor at all times. This approach ensures stability and helps the client maintain balance while using the cane. Choice A is incorrect because the cane should be used on the stronger side of the body to provide additional support. Choice B is incorrect as advancing the cane and the strong leg together may compromise stability. Choice D is incorrect as advancing the cane too far with each step can lead to imbalance and falls.

Correct Answer: A

Rationale: The correct answer is to check for air leaks in the tubing every 4 hours when caring for a client with a chest tube. This responsibility is crucial because it ensures proper chest tube function and helps prevent complications such as pneumothorax or hemothorax. Clamping the chest tube (Choice B) can lead to serious issues by causing a tension pneumothorax. Encouraging deep breathing and coughing (Choice C) is important for respiratory hygiene but is not directly related to chest tube care. Keeping the client in a high Fowler's position (Choice D) may be beneficial for some conditions but is not specific to chest tube management.

Correct Answer: B

Rationale: The correct answer is to check for air leaks in the tubing. Air leaks can compromise the function of the chest tube, leading to inadequate drainage and potentially causing complications for the client. Clamping the chest tube periodically is incorrect as it could lead to a buildup of fluid or air in the pleural space. Keeping the client in a prone position is not necessary for chest drainage, as the positioning may vary depending on the specific situation. Administering diuretics may not be directly related to monitoring the chest tube for proper function and is not a routine intervention for chest tube management post-op.
