A nurse is reviewing laboratory results for a client who has metabolic alkalosis. Which of the following blood gas values should the nurse expect?

A. Attempting to force an object into the oral cavity during muscle contraction causes dental trauma or jaw fractures. It significantly increases the risk of aspiration if the object breaks or triggers a gag reflex. Modern clinical guidelines strictly prohibit the insertion of any device into the mouth during active convulsions. Airway patency is maintained by placing the client in a lateral position.

B. Tracking the exact duration of the ictal phase is a critical nursing responsibility for clinical assessment. This data determines the necessity for emergency benzodiazepines if the event lasts longer than 5 minutes. Precise timing helps differentiate between a self-limiting seizure and dangerous status epilepticus. The nurse must record the start and end times to guide medical intervention.

C. Lowering the side rails during a seizure increases the risk of the client falling from the height of the bed. Standard seizure precautions require that side rails remain raised and should be padded to prevent blunt force trauma. Ensuring the patient stays within the safe boundaries of the bed is a primary safety goal.

D. Physical restraints can cause severe musculoskeletal injuries such as fractures or dislocations during the forceful involuntary movements of the clonic phase. Restricting the extremities creates unnecessary resistance against powerful muscle contractions. The nurse should clear the immediate area of hard objects rather than holding the client down.

A) Place the client in Sims' position for catheter insertion: Sims' position (side-lying position) is not typically used for central venous catheter insertion. The client is usually placed in a supine or Trendelenburg position to help facilitate insertion and decrease the risk of air embolism during the procedure.

B) Prepare the client for a chest x-ray to verify catheter placement: After the insertion of a central venous catheter, a chest x-ray is routinely performed to verify the correct placement of the catheter in the superior vena cava or right atrium. This is essential to ensure the catheter is properly positioned and to check for complications like pneumothorax or inadvertent placement in the lung.

C) Use clean technique when changing the catheter dressing: When changing the dressing for a central venous catheter, sterile technique is required, not clean technique. Sterile technique minimizes the risk of infection, which is a major concern when caring for central venous access devices.

D) Verify the amount of TPN solution the client is receiving every 4 hr: While it is important to monitor the amount of TPN being infused and assess for complications, verifying the exact amount every 4 hours is not a standard procedure. Typically, TPN is managed and adjusted by the healthcare provider based on lab results, weight, and clinical status, but constant monitoring of the solution is not required.
