A client in the recovery room following a procedure is unable to void, so the nurse obtains a prescription to perform a straight catheterization. After inserting the catheter, the nurse observes that the client has an immediate output of 500 mL of clear yellow urine. Which action should the nurse implement next?

Choice A reason: This is a correct answer because continuing to monitor the client for signs of an infection is important to detect any recurrence or complication of MRSA infection. MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious skin, soft tissue, bone, joint, or bloodstream infections. The nurse should assess the client's vital signs, wound appearance, pain level, and laboratory results.

Choice B reason: This is not a correct answer because calling the healthcare provider for a prescription for linezolid is not necessary unless the client has an active MRSA infection that requires treatment. Linezolid is an antibiotic that can be used to treat MRSA infections, but it has potential side effects and interactions that need to be considered. The nurse should not prescribe or administer antibiotics without a valid order.

Choice C reason: This is a correct answer because collecting multiple sets of blood cultures for MRSA screening is important to identify any asymptomatic bacteremia or sepsis that could result from MRSA infection. MRSA can enter the bloodstream through wounds, catheters, or surgical sites and cause life-threatening complications such as endocarditis, osteomyelitis, or pneumonia. The nurse should obtain blood samples from different sites and times and send them to the laboratory for analysis.

Choice D reason: This is a correct answer because placing the client on contact transmission precautions is important to prevent the spread of MRSA to other clients, staff, or visitors. Contact transmission precautions include wearing gloves and gowns when entering the client's room, using dedicated or disposable equipment, and performing hand hygiene before and after contact with the client or their environment.

Choice E reason: This is not a correct answer because obtaining a sputum specimen for culture and sensitivity is not relevant to the client's history of MRSA wound infection. Sputum culture and sensitivity is a test that can be used to diagnose respiratory infections caused by bacteria, fungi, or viruses. The nurse should only obtain a sputum specimen if the client has signs or symptoms of a respiratory infection, such as cough, fever, chest pain, or dyspnea.

Choice A: Conversion of the client's PPD test from negative to positive is not the most important information for the nurse to note, as this is an expected finding for a client who has been exposed to tuberculosis and does not affect the administration of isoniazid. This is a distractor choice.

Choice B: History of intravenous drug abuse is not the most important information for the nurse to note, as this is not directly related to the use of isoniazid and does not contraindicate its administration. This is another distractor choice.

Choice C: Current diagnosis of hepatitis B is the most important information for the nurse to note, as this can increase the risk of hepatotoxicity and liver damage from isoniazid, which requires close monitoring and possible dose adjustment. Therefore, this is the correct choice.

Choice D: Length of time of the exposure to tuberculosis is not the most important information for the nurse to note, as this does not influence the dosage or frequency of isoniazid and does not indicate any complication or adverse reaction. This is another distractor choice.
