A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?

Choice A reason: Suctioning the ET removes secretions obstructing airflow, increasing peak airway pressure. Mucus buildup narrows the airway, triggering alarms. Clearing secretions restores patency, reduces pressure, and prevents complications like atelectasis or hypoxia, critical for effective ventilation in mechanically ventilated clients.
Choice B reason: Verifying ET placement ensures the tube is in the trachea. Misplacement, like esophageal intubation, increases airway resistance, elevating peak pressure. Confirmation via capnography or X-ray prevents hypoxia, ensuring proper ventilation and safety in clients on mechanical ventilators.
Choice C reason: Checking for kinks in ventilator tubing addresses mechanical obstructions raising peak airway pressure. Kinks restrict airflow, triggering alarms. Straightening tubing restores normal gas delivery, reducing resistance and maintaining effective ventilation, preventing hypoxia in mechanically ventilated clients.
Choice D reason: Administering a bronchodilator relieves bronchospasm, a common cause of high peak airway pressure. Bronchoconstriction narrows airways, increasing resistance. Bronchodilators relax smooth muscles, improving airflow and reducing pressure, addressing reversible causes like asthma in ventilated clients.
Choice E reason: Increasing tidal volume exacerbates high peak airway pressure, risking barotrauma or lung injury by forcing air against resistance. Addressing underlying causes like secretions or bronchospasm is safer, as higher volumes do not resolve the root issue, potentially worsening outcomes.

Choice A reason: Removing restraints immediately risks safety, as the client’s calm state may not be sustained. Restraints require gradual removal after ensuring sustained behavioral stability, per facility policy and safety standards. Frequent monitoring is needed to assess ongoing safety, making this action premature and potentially unsafe.
Choice B reason: Encouraging group therapy is inappropriate while the client remains in restraints, as it does not address the immediate need to evaluate their behavior for safe restraint removal. Therapy may be beneficial later, but ongoing monitoring is the priority to ensure safety and compliance with restraint protocols.
Choice C reason: Continuing to monitor the client every 15 minutes ensures safety while assessing sustained calm and cooperative behavior. This adheres to restraint protocols, which require frequent checks to evaluate the need for continued restraint, prevent complications, and plan for safe removal, making it the correct action.
Choice D reason: Administering a sedative to maintain calm behavior is inappropriate without a current medical order or ongoing aggression. Sedatives carry risks like oversedation or respiratory depression. Monitoring the client’s behavior is the priority to determine if restraints can be safely discontinued, making this action unnecessary and potentially harmful.
