The nurse is caring for four clients: Client A, who has emphysema and whose oxygen saturation is 94%; Client B, with a postoperative hemoglobin of 8.2 mg/dL (82 g/L); Client C, newly admitted with a potassium level of 3.8 mEq/L (3.8 mmol/L); and Client D, scheduled for an appendectomy who has a white blood cell (WBC) count of 14,000 mm (14 x 10^9/L). Which intervention should the nurse implement? Reference Range:. Hemoglobin [14 to 18 g/dL (140 to 180 g/L)]. Potassium [3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)]. White Blood Cell [5000 to 10,000/mm² (5 to 10 x 10^9/L)].

The correct answer is Choice D. Choice A rationale: Moving Client D into an isolation room 24 hours before surgery is not necessary. The client’s white blood cell (WBC) count is 14,000 mm (14 x 10^9/L), which is higher than the normal range of 5000 to 10,000/mm² (5 to 10 x 10^9/L). This indicates that the client may have an infection. However, it is not standard practice to isolate clients scheduled for surgery based solely on an elevated WBC count. Other factors, such as the presence of specific infectious diseases, would dictate the need for isolation. Choice B rationale: Asking the dietitian to add a banana to Client C’s breakfast tray is not necessary. The client’s potassium level is 3.8 mEq/L (3.8 mmol/L), which is within the normal range of 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Therefore, there is no need to increase the client’s potassium intake. Choice C rationale: Increasing Client A’s oxygen to 4 liters a minute per cannula is not necessary. The client has emphysema and their oxygen saturation is 94%, which is within the normal range. Increasing the oxygen flow rate could lead to oxygen toxicity or suppress the client’s respiratory drive, leading to respiratory depression or failure. Choice D rationale: Verifying that Client B has two units of packed cells available is the correct intervention. The client’s postoperative hemoglobin level is 8.2 mg/dL (82 g/L), which is lower than the normal range of 14 to 18 g/dL (140 to 180 g/L). This indicates that the client is anemic and may require a blood transfusion. Therefore, it is important to ensure that packed cells are available if needed.
