Correct Answer: B

Rationale: Encouraging passive range-of-motion exercises is the most appropriate intervention to help relieve symptoms of joint pain and stiffness in clients with severe rheumatoid arthritis. These exercises help maintain joint mobility, prevent muscle contractures, and reduce stiffness in the affected joints. Passive range-of-motion exercises can also improve circulation to the joints, promoting healing and reducing pain. Applying cold packs may help with inflammation and pain temporarily, but it does not address the long-term joint mobility issues associated with rheumatoid arthritis. Muscle relaxants are not typically indicated for managing joint pain and stiffness in rheumatoid arthritis. While nutrition is important for overall health, providing a high-calorie diet is not a direct intervention for relieving joint pain and stiffness in this context.

Correct Answer: A

Rationale: Placing the client in High Fowler's position is beneficial for individuals with left-sided heart failure experiencing dyspnea and orthopnea. This position helps to reduce venous return, decrease preload, and enhance respiratory function, thereby relieving the symptoms mentioned. Choice B, the supine position, is not recommended as it may exacerbate dyspnea and orthopnea by increasing preload. Choice C, the Trendelenburg position, is incorrect as it involves the feet being positioned higher than the head, which is not suitable for heart failure patients. Choice D, the Sims' position, is a lateral position used for rectal examination and is not indicated for relieving dyspnea and orthopnea in heart failure.

Correct Answer: C

Rationale: The correct instruction for a client prescribed salmeterol (Serevent) is to use it twice daily for long-term control. Salmeterol is a long-acting bronchodilator that is not intended for acute asthma attacks or as-needed use for wheezing. Choice A is incorrect because salmeterol is not used for acute asthma attacks. Choice B is incorrect as salmeterol is not meant to replace the albuterol inhaler but rather used for long-term control. Choice D is incorrect because salmeterol should not be used as needed; it is a maintenance medication for asthma.

Correct Answer: D

Rationale: Decreased vital capacity is the most critical assessment finding in a client with Guillain-Barr© syndrome as it indicates respiratory compromise. This requires immediate intervention to ensure adequate ventilation and prevent respiratory failure, a common complication of this syndrome. Monitoring and maintaining respiratory function are vital in these clients to prevent complications such as respiratory distress, hypoxia, and respiratory failure. Loss of deep tendon reflexes and ascending weakness are typical manifestations of Guillain-Barr© syndrome but do not require immediate action compared to compromised respiratory function. New onset of confusion may be a concern but is not as immediately life-threatening as decreased vital capacity.

Correct Answer: C

Rationale: To prevent autonomic dysreflexia in clients with spinal cord injuries, it is crucial to ensure the client's bladder is emptied regularly. Bladder distention is a common trigger for autonomic dysreflexia in these clients. Keeping the bladder empty helps prevent the complications associated with autonomic dysreflexia, such as dangerously high blood pressure. Choices A, B, and D are incorrect. Restricting fluid intake can lead to dehydration, keeping the room warm is not directly related to preventing autonomic dysreflexia, and limiting high-fiber foods is not a primary intervention for this condition.
