Correct Answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.

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: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

Correct Answer: B

Rationale: The correct answer is B: 'Describe the pain you are experiencing.' This question is the most effective as it prompts the client to provide detailed information about the nature of the pain, including its characteristics, intensity, and location. This detailed description can help the nurse in assessing the possible cause and severity of the pain. Choices A, C, and D are not as effective as they are either too general ('Tell me how you are feeling right now'), redundant ('Can you tell me more about your back pain?'), or focused only on timing and severity ('When did the pain start and how severe is it?').

Correct Answer: D

Rationale: Acupuncture has been effective for the client previously, supporting continued use.
