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)].

Move Client D into an isolation room 24 hours before surgery.

Ask the dietitian to add a banana to Client C's breakfast tray.

Increase Client A's oxygen to 4 liters a minute per cannula.

Verify that Client B has two units of packed cells available.

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

Choice D rationale:

Taking zolpidem before bedtime is the correct information to include in the education. Zolpidem is a medication used for the short-term treatment of insomnia and should be taken immediately before going to bed to facilitate sleep onset.

Choice A rationale:

Crushing zolpidem to increase absorption is not recommended. The medication should be taken whole and not crushed or chewed.

Choice B rationale:

Storing zolpidem at room temperature is correct. Like many medications, zolpidem should be stored at a controlled room temperature, away from moisture and heat.

Choice C rationale:

Administering zolpidem with a meal is not necessary and may delay the onset of its effects. It is typically taken on an empty stomach for faster absorption.

A. Check femoral site for hematoma formation. B. Stimulate the client to take deep breaths. C. Evaluate the integrity of the IV insertion site. D. Assess distal lower extremity capillary refill.

Correct Answer is A

Explanation

Choice A rationale:

Checking the femoral site for hematoma formation is the most appropriate action in response to the client's complaint of pain at the right groin insertion site after a cardiac catheterization. Hematoma formation is a potential complication of this procedure and can lead to further complications if not addressed promptly. Checking for hematoma allows the nurse to assess for bleeding and take appropriate measures to manage it.

Choice B rationale:

Stimulating the client to take deep breaths is not the most immediate action needed in this situation. While deep breathing is important for respiratory function, the client's pain at the groin site requires immediate assessment to rule out complications.

Choice C rationale:

Evaluating the integrity of the IV insertion site is not the primary concern in this case. The client's pain is localized to the groin site, which is where the cardiac catheterization was performed. Checking for hematoma formation at this site takes precedence.

Choice D rationale:

Assessing distal lower extremity capillary refill is important for assessing peripheral perfusion, but it is not the most immediate action needed when a client complains of pain at a specific site, such as the right groin insertion site after a cardiac catheterization. Checking for hematoma and assessing for bleeding should come first.
