Correct Answer: B

Rationale: Phlebitis, inflammation of a vein, is a complication that requires prompt action. The most appropriate next step is to discontinue the IV infusion and notify the healthcare provider. Applying a warm compress, increasing the IV flow rate, or applying an ice pack are not appropriate interventions for phlebitis. Warm compresses may worsen inflammation, increasing the IV flow rate could exacerbate the condition, and ice packs are not recommended for phlebitis.

Correct Answer: B

Rationale: The correct answer is to wipe the drainage port after emptying. This action helps reduce the risk of infection by maintaining cleanliness. Positioning the drainage bag below the bladder (choice A) is incorrect as it should be positioned below the level of the bladder to prevent backflow of urine. Inserting the catheter using sterile technique (choice C) is not necessary for routine emptying of the drainage bag. Avoiding cleansing the urinary meatus (choice D) is incorrect as proper hygiene should be maintained to prevent infections.

Correct Answer: B

Rationale: The priority when managing a client with a chest tube postoperatively is to check for air leaks and ensure the proper functioning of the chest tube. This is crucial to prevent complications such as pneumothorax or hemothorax. Clamping the chest tube intermittently can lead to a buildup of pressure in the pleural space and should not be done without a specific medical indication. Encouraging deep breathing and coughing helps with lung expansion but is not the priority over ensuring the chest tube's proper function. Encouraging frequent coughing may increase the risk of dislodging the chest tube or causing complications.
