Correct Answer: A

Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.

Correct Answer: D

Rationale: The correct answer is D: Upper body muscle strength. The ability to use a trapeze bar requires adequate upper body strength to support the weight and facilitate repositioning. While assessing pain, coordination, and cognitive status are important, the priority is determining if the client can physically manage the trapeze bar safely. Without sufficient upper body muscle strength, the client may not be able to use the trapeze bar effectively and safely. Assessing balance and coordination is also important but secondary to ensuring the client has the required upper body strength. Cognitive status is crucial for understanding instructions related to using the trapeze bar, but it is not the most critical assessment in this scenario. Pain assessment is essential for overall care but does not directly impact the client's ability to use a trapeze bar like upper body muscle strength does.

Correct Answer: B

Rationale: For a client with severe neutropenia, it is crucial to recommend a snack that is low in bacteria to reduce the risk of infection. Yogurt with fresh berries is an excellent choice as it is not only low in bacteria but also provides nutritional value. Baked apples with raisins (choice A) may not be ideal as the preparation process could introduce bacteria. Avocados and cheese (choice C) may not be the best option due to their potential bacterial content. Fresh fruit salad (choice D) may have a higher risk of bacterial contamination compared to yogurt with fresh berries.

Correct Answer: A

Rationale: The correct first action for the nurse is to stop the transfusion and notify the healthcare provider. These symptoms suggest a transfusion reaction, and stopping the transfusion is crucial to prevent further complications. Notifying the healthcare provider ensures timely intervention and appropriate management for the client's condition. Monitoring vital signs, administering diphenhydramine, or preparing to administer an antihistamine can be considered after stopping the transfusion and seeking guidance from the healthcare provider. However, the immediate priority is to halt the transfusion and inform the provider.

Correct Answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.
