A nurse is planning care for a client who is an hr postoperative following a coronary artery bypass grafting. Which of the following assessments should the nurse plan to perform first?

A. Initiate cardiac monitoring for the client: Cardiac monitoring is important but should not occur before assessing the client's immediate circulatory status. Monitoring provides information about electrical activity but does not replace the need to confirm whether the client has a pulse, which determines the next steps in emergency care.

B. Establish an IV access: Establishing IV access is useful for administering emergency medications, but it should not occur until the nurse determines whether the client has a pulse. Interventions requiring vascular access are secondary to assessing airway, breathing, and circulation.

C. Palpate for the client's carotid pulse: The first priority in an unresponsive but breathing client is to assess circulation by checking for a carotid pulse. Determining whether the client has a pulse guides the nurse to initiate CPR if pulseless or continue supportive care if the pulse is present. This assessment directs all subsequent actions in the emergency response.

D. Apply a blood pressure cuff: Measuring blood pressure is part of a full assessment but is not the first action in an unresponsive client. Vital signs can be obtained after confirming pulse and ensuring that immediate life-threatening conditions are addressed.

A. Limiting protein intake: While some clients with kidney disease may need to moderate protein intake, routine protein restriction is not the primary strategy to prevent diabetic nephropathy. Excessive restriction can lead to malnutrition and is not as effective as controlling underlying risk factors.

B. Controlling hypertension: Maintaining blood pressure within the target range is a key intervention to prevent or slow the progression of diabetic nephropathy. Hypertension accelerates kidney damage in diabetes, so controlling blood pressure helps preserve renal function and reduces the risk of complications.

C. Decreasing potassium intake: Reducing potassium intake is only necessary for clients who develop hyperkalemia due to kidney impairment. It is not a preventive measure for nephropathy in clients with normal kidney function. Routine potassium restriction is not indicated without lab evidence.

D. Voiding every 2 hr: Frequent voiding is not a preventive strategy for nephropathy. While monitoring urine output can help detect changes in kidney function, scheduled voiding does not protect against kidney damage caused by diabetes or hypertension.
