Correct Answer: D

Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.

Correct Answer: C

Rationale: The most accurate method to confirm the proper placement of a nasogastric tube is by examining a chest x-ray obtained after the tubing was inserted. This visual assessment allows healthcare providers to directly visualize the position of the tube in relation to anatomical landmarks, ensuring it is correctly placed in the stomach. Aspirating gastric contents or hearing air pass may provide some information but are not as definitive as a chest x-ray for confirming placement. Checking the remaining length of tubing is not a reliable method for determining proper placement as it does not indicate where the tip of the tube lies within the body.

Correct Answer: B

Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client's care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.

Correct Answer: A

Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.

Correct Answer: D

Rationale: The correct response when a student nurse is caught taking a copy of a client's medication administration record is to explain that the records are hospital property and cannot be removed. It is essential to educate the student about the confidentiality and security of patient information, emphasizing that even with the client's consent, such actions are unacceptable. Option A is not the immediate action needed, as addressing the student directly should come first. Option B involves notifying another party before addressing the student directly. Option C is incorrect because even if the client gave permission, patient records are confidential and cannot be shared without authorization.
