A client tells the nurse of concerns about possibly having a stomach ulcer because the client is experiencing heartburn and a dull gnawing pain that is relieved by eating. Which is the best response by the nurse?

Choice A reason: Before administering IV fluids containing potassium chloride, it is crucial to ensure that the client has adequate urinary output, typically between 30 to 60 mL/hr. This indicates good kidney function, which is necessary for the excretion of potassium to prevent hyperkalemia, a potentially life-threatening condition.

Choice B reason: While magnesium levels can affect potassium levels, they are not the most critical assessment before potassium infusion. However, it is important to monitor magnesium levels as part of the overall electrolyte balance, especially in diabetic ketoacidosis.

Choice C reason: The size of the IV catheter is important for administration purposes, but it is not the most critical assessment data before starting potassium infusion. The catheter size affects the flow rate and comfort during infusion but does not impact the decision to start the infusion.

Choice D reason: Serum glucose level is a vital parameter to monitor in diabetic ketoacidosis, but it is not the most critical assessment before starting potassium infusion. The primary concern with potassium infusion is kidney function, as assessed by urinary output.

Choice A reason: Applying sequential compression stockings when in bed is a recommended postoperative intervention for bariatric surgery patients. It helps prevent deep vein thrombosis (DVT) by promoting venous return and reducing venous stasis, which is particularly important in patients with obesity due to their increased risk for DVT.
Choice B reason: Maintaining strict bedrest for 12 hours after surgery is not typically recommended as it can increase the risk of complications such as DVT and pulmonary embolism. Early mobilization is generally encouraged to promote circulation and respiratory function.
Choice C reason: Providing chilled beverages is not a specific nursing intervention indicated in the immediate postoperative period for bariatric surgery patients. Fluid intake should be carefully monitored and regulated, but the temperature of the beverages is not a primary concern.
Choice D reason: Changing position frequently is an important postoperative intervention to prevent complications such as pressure ulcers and to promote lung expansion, especially in patients with obesity who are at higher risk for these issues.
Choice E reason: Encouraging coughing and deep breathing is essential after bariatric surgery to help clear the airways, prevent atelectasis, and improve oxygenation. This is particularly important for this patient who has a history of sleep apnea and reported diminished breath sounds postoperatively.
Choice F reason: Observing for signs and symptoms of dumping syndrome is relevant for bariatric surgery patients, as this syndrome can occur when food moves too quickly from the stomach to the small intestine. However, this is more of a long-term concern rather than an immediate postoperative intervention.
Choice G reason: Keeping the client NPO (nothing by mouth) is a common immediate postoperative order, but as the patient progresses, they will be started on a liquid diet and advanced as tolerated. Therefore, it is not a nursing intervention that would be indicated indefinitely.
Choice H reason: Maintaining the head at a 45-degree angle can help improve respiratory function by reducing pressure on the diaphragm, which is especially beneficial for patients with obesity and a history of sleep apnea, as in this case.
