A nurse is caring for a client who has a prescription for a continuous passive motion (CPM) machine following a total knee arthroplasty. Which of the following actions should the nurse take?
Turn off the CPM machine during mealtime.
Maintain the client's affected hip in an externally rotated position.
Instruct the client how to adjust the CPM settings for comfort.
Store the CPM machine under the client's bed when not in use.
The Correct Answer is A
- A. Correct. The nurse should turn off the CPM machine during mealtime, as it can interfere with the client's ability to eat and drink comfortably. The nurse should also turn off the CPM machine when transferring or repositioning the client, or when performing wound care or other interventions on the affected leg.
- B. Incorrect. The nurse should maintain the client's affected hip in a neutral position, as external rotation can cause malalignment of the prosthesis and impair healing. The nurse should use pillows or wedges to support the leg and prevent rotation or abduction of the hip joint.
- C. Incorrect. The nurse should not instruct the client how to adjust the CPM settings, as this can compromise the prescribed range of motion and speed of the device. The nurse should follow the provider's orders and check with them before making any changes to the CPM settings. The nurse should also monitor the client's pain level and administer analgesics as needed to facilitate compliance with the therapy.
- D. Incorrect. The nurse should not store the CPM machine under the client's bed when not in use, as this can pose a safety hazard and damage the equipment. The nurse should place the CPM machine on a stable surface near the bed and ensure that it is plugged into a grounded outlet and has adequate battery backup in case of power failure.

Correct Answer is A
Explanation
- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.
- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.
- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.
- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs
Correct Answer is A
Explanation
Irritability.
The rationale for each choice is as follows:
- A. Irritability: Correct. Irritability is one of the signs of hypoglycemia, which occurs when blood glucose levels fall below 70 mg/dL (3.9 mmol/L). Other signs include shakiness, sweating, hunger, headache, confusion, and blurred vision.
- B. Increased urination: Incorrect. Increased urination is one of the signs of hyperglycemia, which occurs when blood glucose levels rise above 180 mg/dL (10 mmol/L). Other signs include thirst, dry mouth, fatigue, nausea, and fruity breath odor.
- C. Vomiting: Incorrect. Vomiting is not a specific sign of hypoglycemia or hyperglycemia, but it can occur as a complication of either condition if left untreated or poorly managed.
- D.Facial flushing: Incorrect. Facial flushing is not a sign of hypoglycemia or hyperglycemia, but it can occur as a side effect of some medications used to treat diabetes, such as niacin or rosiglitazone.
