Correct Answer: D

Rationale: The correct answer is D: Serum albumin 3.5 g/dL. A low serum albumin level indicates protein deficiency, which can be a complication of TPN therapy and requires prompt intervention. The other laboratory findings provided (serum calcium 8.5 mg/dL, blood glucose level 120 mg/dL, and serum sodium 138 mEq/L) are within normal ranges and do not specifically indicate complications related to TPN therapy.

Correct Answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial to monitor in patients receiving warfarin therapy. INR measures the blood's ability to clot and is used to ensure that patients are within the therapeutic range for warfarin therapy. This is important to prevent both clotting disorders and bleeding complications. Monitoring potassium levels (choice B) is not directly related to warfarin therapy. Platelet count (choice C) and sodium levels (choice D) are important parameters but are not as critical to monitor specifically for patients on warfarin therapy.

Correct Answer: D

Rationale: The correct answer is D: 'Avoid taking aspirin while using this medication.' Enoxaparin is an anticoagulant medication, and taking aspirin concurrently can increase the risk of bleeding. Choices A, B, and C are incorrect. A nurse should not instruct the client to rub the injection site after administration as it may cause irritation. Pinching the skin while administering the injection is not recommended for enoxaparin injections. Aspirating before administering the medication is also unnecessary as enoxaparin is administered subcutaneously, not intramuscularly.

Correct Answer: D

Rationale: Corrected Rationale: Chicken breast is an excellent source of protein, which is essential for wound healing due to its role in tissue repair and regeneration. Fish is also a good source of protein, but chicken breast is a more commonly recommended option for wound healing due to its high protein content and lower fat content compared to some types of fish. Bananas and white bread, on the other hand, are not high-protein foods and do not provide the necessary nutrients for wound healing.

Correct Answer: B

Rationale: Redness and warmth in the calf can indicate a deep vein thrombosis (DVT), which is a serious complication following hip replacement surgery. It is crucial to report this finding promptly for further evaluation and intervention. The other options, heart rates of 88/min and 96/min, are within normal limits for an adult and may not require immediate reporting. A urine output of 30 mL/hr is concerning for decreased kidney perfusion, but the priority in this case is the potential DVT due to its severe implications.
