Correct Answer: A

Rationale: The correct action is to commend the client for selecting a high biological value protein, as scrambled eggs provide a good protein source for clients with chronic renal failure. Protein is essential for maintaining muscle mass and overall health in these clients. Reminding the client to avoid protein is incorrect as it may lead to protein-energy malnutrition, which is a common concern in chronic renal failure. Suggesting orange juice for absorption is not relevant to the situation, as protein absorption is not a primary concern in this context. Encouraging the client to attend classes on dietary management of chronic renal failure is important for overall education but is not the immediate action needed in response to the client's breakfast choice.

Correct Answer: D

Rationale: In this scenario, the nurse should instruct the client to take deep, rhythmic breaths as a nonpharmacological pain management technique. Deep, rhythmic breathing helps with relaxation and pain management, potentially reducing the perception of pain. Encouraging the client to apply a heating pad for 2 hours at a time (Choice A) is not recommended as prolonged heat application can lead to tissue damage and is not suitable for mild back pain. Applying an ice pack for 1 hour (Choice B) may not be appropriate for mild back pain as cold therapy is more commonly used for acute injuries. Removing distractions from the client's room (Choice C) may help create a more calming environment, but it does not directly address the client's pain.

Correct Answer: B

Rationale: Reflecting is the correct answer as it involves echoing back the client's feelings and concerns, helping them explore their thoughts. In this scenario, the nurse mirrors the client's statement to encourage the client to delve deeper into their emotions. Pacing involves matching the rate and flow of communication, paraphrasing is restating in different words, and restating is repeating what the client said without adding new information. Therefore, choices A, C, and D are not the appropriate clarifying technique demonstrated in the situation described.

Correct Answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

Correct Answer: A

Rationale: Cheddar cheese is the correct answer as it is a good source of complete protein that contains all essential amino acids required for maintaining a positive nitrogen balance for wound healing. Complete proteins provide all essential amino acids needed by the body. White rice, apples, and green beans do not offer complete proteins like cheddar cheese, making them inadequate choices for this purpose.
