A nurse is caring for a client who has methicillin-resistant Staphylococcus aureus (MRSA) in an abdominal wound. The nurse enters the room to check the client's pulse. Which of the following items should the nurse wear?

Choice A reason: A systemic infection would affect the entire body or multiple systems, not just the urinary tract. While a urinary tract infection can become systemic if it leads to sepsis, the scenario provided does not specify such progression.

Choice B reason: A health care-associated infection (HAI) is an infection that a patient acquires while receiving treatment for another condition within a healthcare setting. Since the infection occurred after the insertion of a urinary catheter in a hospital, it is considered an HAI.

Choice C reason: An endogenous infection originates from the host's own microbial flora. The scenario does not provide enough information to determine if the infection was caused by the client's own flora or by external sources.

Choice D reason: An exogenous infection comes from outside the body. While the urinary tract infection could be exogenous, the scenario suggests it is more likely to be health care-associated due to the timing and context of the catheter insertion.

Choice A reason: The carotid pulse sites should not be checked bilaterally at the same time because palpating both carotid arteries simultaneously can restrict blood flow to the brain and may also stimulate the vagus nerve, potentially causing bradycardia or even syncope.

Choice B reason: The popliteal pulse, located at the back of the knee, can be checked bilaterally without the risk of restricting blood flow to vital organs or stimulating a vagal response.

Choice C reason: The femoral pulse, found in the groin area, can also be checked bilaterally as it does not pose the same risks as the carotid pulse when checked simultaneously.

Choice D reason: The brachial pulse, located on the inside of the arm just above the elbow, is another site that can be checked bilaterally without significant risk.
