A nurse is teaching a client about the uses of chamomile. Which of the following information should the nurse include in the teaching?

Choice A reason: Discussing the visitation policy is important for the client’s overall hospital experience but does not directly relate to the prevention of postoperative complications. Visitation policies help manage the flow of visitors and ensure the client gets adequate rest, but they do not address specific postoperative risks.

Choice B reason: Instructing the client about the use of a sequential compression device is crucial for preventing deep vein thrombosis (DVT) and pulmonary embolism, which are common postoperative complications. Sequential compression devices (SCDs) help improve blood circulation in the legs, reducing the risk of blood clots forming during periods of immobility after surgery.

Choice C reason: Teaching the client how to use the PCA pump (patient-controlled analgesia) is important for pain management but does not directly prevent postoperative complications. Proper pain management can aid in recovery by allowing the client to move and breathe more effectively, but it is not a primary preventive measure for complications like DVT or infections.

Choice D reason: Reviewing the pain scale helps the client communicate their pain levels effectively, which is important for managing postoperative pain. However, like the PCA pump, it does not directly prevent complications. Effective pain management can contribute to overall recovery but is not a standalone preventive measure.

Choice A reason: 0.9% sodium chloride, also known as normal saline, is not the best choice for interim fluid replacement when TPN is delayed. While it can maintain hydration and electrolyte balance, it does not provide the necessary calories that TPN supplies. TPN solutions are rich in dextrose, amino acids, and lipids, which are essential for patients who cannot receive nutrition through their gastrointestinal tract.

Choice B reason: Dextrose 5% in water (D5W) provides some calories but not enough to meet the nutritional needs of a patient who is dependent on TPN. D5W contains 5 grams of dextrose per 100 mL, providing 170 calories per liter. This is insufficient for patients who require high-calorie intake due to their inability to eat or absorb nutrients normally.

Choice C reason: Dextrose 10% in water (D10W) is the most appropriate choice for interim fluid replacement when TPN is delayed. D10W provides 10 grams of dextrose per 100 mL, offering 340 calories per liter. This higher concentration of dextrose helps to maintain the patient’s caloric intake and prevent hypoglycemia until the next TPN container is available.

Choice D reason: Lactated Ringer’s solution is primarily used for fluid and electrolyte replacement. It contains sodium, potassium, calcium, chloride, and lactate, but it does not provide the necessary calories that TPN supplies. Therefore, it is not suitable for maintaining the nutritional needs of a patient who is dependent on TPN.
