A client diagnosed with type II diabetes controlled with a biguanide medication and a history of liver disease is scheduled for a computed tomography (CT) scan with contrast medium of the abdomen to evaluate pancreatic function.
Which intervention should the nurse implement?
Administer a laxative to cleanse the bowel before the CT scan.
Administer the biguanide medication as scheduled.
Advise the client to fast for 24 hours before the CT scan.
Ensure the client is adequately hydrated before the CT scan.
The Correct Answer is D
Choice A rationale
Administering a laxative is not necessary for a CT scan of the abdomen with contrast. Laxatives are typically used for bowel preparation for procedures like colonoscopies.
Choice B rationale
Biguanide medications such as metformin should be held before and after the administration of contrast medium to prevent lactic acidosis, particularly in clients with liver disease.
Choice C rationale
Fasting for 24 hours is not required before a CT scan with contrast medium. Typically, clients are asked to fast for a few hours prior to the procedure.
Choice D rationale
Ensuring the client is adequately hydrated helps to protect kidney function and reduce the risk of contrast-induced nephropathy. Hydration is especially important for clients with a history of liver disease.

Correct Answer is B
Explanation
Choice A rationale
Checking the blood pressure is not the priority action in this case. The symptoms described may suggest compartment syndrome, which is a medical emergency and requires immediate intervention.
Choice B rationale
The correct action is to notify the health care provider immediately as this may indicate compartment syndrome, a serious complication that can occur after fractures and can lead to permanent damage if not treated promptly.
Choice C rationale
Assessing the incision for redness is not appropriate in this scenario as the symptoms suggest a more severe underlying issue such as compartment syndrome, which requires urgent attention.
Choice D rationale
Repositioning the leg may provide temporary relief but does not address the potential underlying issue of compartment syndrome. The priority is to notify the health care provider.
Correct Answer is C
Explanation
Choice A rationale
Clamping the chest tube can cause increased pressure in the pleural space and is not appropriate without specific indications.
Choice B rationale
Increasing the wall suction may not relieve the burning sensation and could potentially cause harm.
Choice C rationale
Repositioning the client can help alleviate the burning sensation by adjusting the position of the chest tube and the lung.
Choice D rationale
Stripping the chest tube is not recommended as it can increase intrathoracic pressure and cause damage.
