Correct Answer: B

Rationale: Weighing the client daily to monitor fluid balance is crucial for clients with heart failure. This intervention helps assess for fluid retention or depletion, providing valuable information for managing the condition effectively. Encouraging increased fluid intake (Choice A) is contraindicated in heart failure as it can worsen fluid overload. Restricting fluid intake during meals (Choice C) may lead to dehydration, which is harmful for clients with heart failure. Limiting daily activity (Choice D) is not recommended as appropriate activity levels should be encouraged for overall well-being, under guidance to prevent excessive fatigue.

Correct Answer: B

Rationale: The correct answer is to monitor the client's weight daily to assess fluid balance in clients with chronic heart failure. Monitoring weight helps in detecting fluid retention or fluid loss, which is crucial in managing heart failure. Encouraging fluid intake to prevent dehydration (choice A) may worsen fluid overload in heart failure patients. Limiting sodium intake (choice C) is essential but not the most important intervention compared to monitoring weight. Restricting daily activity (choice D) is not recommended as it is important for clients with heart failure to engage in appropriate levels of physical activity to maintain their overall health.

Correct Answer: D

Rationale: During a 12-lead ECG, the client needs to remain still to obtain accurate readings. Therefore, instructing the client to remain still is essential. Choices A, B, and C are incorrect because fasting is not necessary for an ECG, providing a warm blanket is not a standard procedure, and applying cold compresses may interfere with the ECG results.

Correct Answer: B

Rationale: The correct answer is B: 'Keep oxygen tanks upright at all times.' Oxygen tanks should be stored in an upright position to prevent leaks and accidents. Choice A is incorrect as smoking should never be allowed near oxygen due to the risk of fire. Choice C is incorrect as oxygen equipment should be stored in a well-ventilated area, not in a closet. Choice D is incorrect as oxygen tanks must be kept a minimum of 5 to 10 feet away from heat sources to prevent combustion. Therefore, the best practice is to keep oxygen tanks upright to ensure safety.

Correct Answer: C

Rationale: The correct answer is C: Restore the client's self-control. When managing a physically assaultive client, the nurse's responsibility is to help the client regain control over their actions and emotions. This is crucial in preventing harm to themselves and others. Restricting the client to the room (Choice A) may escalate the situation and is not a therapeutic approach. Placing the client under one-to-one supervision (Choice B) is important for safety but does not address the root cause of the behavior. Clearing the area of other clients (Choice D) is necessary for safety but does not directly address the client's self-control. Therefore, the priority in managing an assaultive client is to focus on restoring their self-control.
