Correct Answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the risk of hyperglycemia. TPN solutions are high in glucose, and clients may be at risk of developing hyperglycemia if the infusion rate is too high or if there are underlying issues such as insulin resistance. Monitoring serum potassium (choice A) is important but not the most crucial value to monitor in clients receiving TPN. Serum sodium (choice C) and serum calcium (choice D) are not directly impacted by TPN administration and are less likely to be affected compared to blood glucose levels.

Correct Answer: C

Rationale: Expectoration of blood is a potential complication following SMR surgery, as it may indicate bleeding postoperatively. In contrast, occipital headache (choice A) is not a common complication associated with SMR surgery. Periorbital crepitus (choice B) is more related to facial fractures or certain infections rather than SMR surgery. Changes in vocalization (choice D) are not typically associated with complications following SMR surgery.

Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to initiate contact precautions. MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacterium that spreads through direct contact. Contact precautions involve wearing gloves and gowns to prevent the spread of infection to other patients or healthcare workers. Force-feeding oral fluids, requesting a nutrition consult, or limiting visitors to immediate family only are not the most appropriate actions in this scenario. These actions do not directly address the need to prevent the spread of MRSA, which is crucial in a healthcare setting.

Correct Answer: A

Rationale: Using tracheostomy covers when outdoors is essential to protect the tracheostomy from dust and debris, reducing the risk of infection. Tracheostomy covers help maintain cleanliness and prevent foreign particles from entering the stoma. Choice B is incorrect because cleaning the tracheostomy with alcohol can be too harsh and drying for the skin surrounding the stoma, leading to skin irritation. Choice C is incorrect as tracheostomy tubes are typically replaced only when clinically indicated or as per the healthcare provider's instructions, not routinely every week, to prevent unnecessary risks and complications. Choice D is incorrect as covering the tracheostomy with a wet cloth when sleeping can create a moist environment ideal for bacterial growth, increasing the risk of infection and skin breakdown. It is important to keep the tracheostomy site clean, dry, and protected to maintain optimal hygiene and prevent complications.
