Correct Answer: B

Rationale: The correct answer is B: 'Monitor the client's weight daily to assess fluid balance.' When caring for a client with heart failure on fluid restriction, it is essential to monitor their weight daily to evaluate fluid balance accurately. This helps healthcare providers assess if the client is retaining excess fluid, a common issue in heart failure. Choices A, C, and D are incorrect. Encouraging the client to drink water throughout the day contradicts fluid restriction. Limiting fluid intake during meals may not provide a comprehensive assessment of fluid balance, and weighing the client once a week is not frequent enough to detect rapid changes in fluid status that could worsen heart failure symptoms.

Correct Answer: B

Rationale: The correct answer is B: 'Keep the oxygen equipment away from heat sources.' Placing oxygen equipment near heat sources can lead to fire hazards due to the flammability of oxygen. Cotton bedding or wool blankets are not directly related to oxygen safety measures. Allowing electronic devices near the oxygen supply can increase the risk of fire due to potential sparks or heat generated.

Correct Answer: C

Rationale: The correct method for teaching a client to use a cane when they have left-leg weakness is to maintain two points of support on the floor at all times. This approach ensures stability and helps the client maintain balance while using the cane. Choice A is incorrect because the cane should be used on the stronger side of the body to provide additional support. Choice B is incorrect as advancing the cane and the strong leg together may compromise stability. Choice D is incorrect as advancing the cane too far with each step can lead to imbalance and falls.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid lying down after meals.' This instruction is important for clients with GERD as it helps reduce reflux symptoms. Lying down after meals can worsen GERD symptoms by allowing stomach acid to flow back into the esophagus. Choice B is incorrect because eating large meals can actually increase acid production and exacerbate GERD symptoms. Choice C is incorrect as carbonated beverages can trigger acid reflux in individuals with GERD. Choice D is also incorrect because consuming spicy foods can irritate the esophagus and lead to increased reflux symptoms.

Correct Answer: D

Rationale: In the scenario described, the manic client is in the seclusion room, and it is most appropriate for the nurse to serve the meal to the client in the seclusion room. This action helps maintain the client's nutritional needs while managing their behavior. Taking the client to the dining room with 1:1 supervision (Choice A) may pose safety risks both for the client and others. Informing the client they may go to the dining room when they control their behavior (Choice B) may not be feasible in a manic state. Holding the meal until the client is able to come out of seclusion (Choice C) can lead to nutritional deficiencies and does not address the immediate need for nutrition during the episode of mania.
