Correct Answer: A

Rationale: The correct answer is A: Administer a bronchodilator immediately. Wheezing in a client with asthma indicates bronchoconstriction, which can compromise airflow. Administering a bronchodilator is the priority intervention as it helps to open the airways, relieve bronchoconstriction, and improve breathing. Increasing the oxygen flow rate (choice B) may be necessary but is not the priority when the airways are constricted. Performing a chest x-ray (choice C) is not the immediate action needed in this situation. Placing the client in a high Fowler's position (choice D) may provide some relief, but administering a bronchodilator to address the bronchoconstriction is the priority intervention.

Correct Answer: D

Rationale: During a tonic-clonic seizure, the nurse should loosen restrictive clothing to prevent injury and ease the client to the floor to ensure safety. Placing any object, such as a tongue depressor, in the client's mouth is contraindicated as it may cause harm. Restraint should not be used as it can lead to injury. Beginning CPR is not indicated during a seizure unless the client experiences cardiac arrest, which is a rare complication of seizures.

Correct Answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.

Correct Answer: B

Rationale: The correct answer is B: Prothrombin time (PT) and International Normalized Ratio (INR). These lab values are crucial for monitoring the effectiveness of warfarin, an anticoagulant medication. PT measures the time it takes for blood to clot, while INR standardizes these results. Ensuring the client's PT/INR levels are within the therapeutic range is essential to prevent clotting or excessive bleeding. Choices A, C, and D are incorrect as they are not directly related to monitoring warfarin therapy in a client with atrial fibrillation.

Correct Answer: B

Rationale: The most critical instruction to include in the discharge teaching plan for a liver transplant client is to take immunosuppressant medications as prescribed. This is vital to prevent organ rejection and ensure the success of the transplant. While ensuring daily follow-up with the healthcare provider is important for monitoring progress, avoiding crowds for the first two months after surgery helps reduce the risk of infections but is not as crucial as medication adherence. Returning to work in three months is a consideration but not the most important aspect immediately post-transplant.
