The healthcare provider prescribes a 5% dextrose injection with 20 units of regular insulin for a client with a serum potassium level of 6.0 mEq/L (6.0 mmol/L) and glucose level of 180 mg/dL (10.0 mmol/L). Which evaluation is most important for the nurse to include in this client's plan of care?

Reference Range:

Potassium [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]

Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Choice A reason: After cardiac catheterization, monitoring the client's vital signs and telemetry pattern is crucial, especially when symptoms like weakness and dizziness are reported. These symptoms could indicate serious complications such as bleeding, arrhythmia, or cardiac tamponade. Monitoring vital signs can help detect hypotension, hemorrhage, or other hemodynamic instabilities. Telemetry is crucial for detecting arrhythmias that may require immediate intervention.

Choice B reason: Palpating and comparing pedal pulse volumes is an important step to assess for vascular complications such as thrombosis or embolism. However, it is not the immediate priority when a client reports systemic symptoms like weakness and dizziness, which could be signs of more serious conditions.

Choice C reason: Measuring post-procedure intake and output is part of routine postoperative care to ensure proper fluid balance. While important, it is not the most critical action to take when a client is experiencing acute symptoms that could indicate life-threatening complications.

Choice D reason: Removing the dressing and observing the site might be indicated if there is suspicion of bleeding or hematoma formation at the catheterization site. However, since the dressing is reported to be dry and intact, and the client is experiencing systemic symptoms, the priority is to assess for potential systemic complications first.

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.
