The nurse is providing lifestyle change education for a client to slow the progression of coronary artery disease. Which statement(s) made by the client should the nurse recognize as needing additional education? (Select all that apply.)

Choice A: Yellow-tinged sputum is not a critical finding for the nurse to report, as this is a common sign of pneumonia and does not indicate an adverse reaction to meropenem. This is a distractor choice.

Choice B: Nausea and headache are not urgent findings for the nurse to report, as these are mild side effects of meropenem and can be managed with supportive measures. This is another distractor choice.

Choice C: Watery diarrhea is an important finding for the nurse to report, as this can indicate a serious complication of meropenem, such as Clostridioides difficile infection, which can cause severe dehydration, electrolyte imbalance, and sepsis. Therefore, this is the correct choice.

Choice D: Increased fatigue is not a significant finding for the nurse to report, as this can be related to the client's underlying condition and does not suggest a problem with meropenem. This is another distractor choice.

Choice A: Securing chest tube to the stretcher for transport is a good practice, but it is not the most important action. The chest tube should be secured to prevent accidental dislodgement or kinking, but it does not affect the function of the chest tube or the drainage system.

Choice B: Administering PRN pain medication prior to transport is a compassionate action, but it is not the most important action. The client may experience pain due to the chest tube, the intubation, or the underlying condition, but pain relief is not a priority over maintaining adequate ventilation and drainage.

Choice C: Marking the amount of chest drainage on the container is a useful action, but it is not the most important action. The amount of chest drainage should be recorded and reported to monitor the client's status and detect any complications, such as hemorrhage or infection, but it does not affect the immediate function of the chest tube or the drainage system.

Choice D: Keeping the chest tube container below the site of insertion is the most important action for the nurse to take. The chest tube container should be kept below the level of the client's chest to maintain a gravity-dependent pressure gradient that allows air and fluid to drain from the pleural space. If the container is raised above the site of insertion, it can cause backflow of air or fluid into the pleural space, which can compromise ventilation and cause tension pneumothorax.
