Prior to administering warfarin to a client with a history of atrial fibrillation, what lab result should the nurse review?

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: 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: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.

Correct Answer: A

Rationale: The correct answer is to monitor potassium levels. Spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium and excrete sodium. Monitoring potassium levels closely is essential because spironolactone can cause hyperkalemia (high potassium levels). Sodium levels are not typically affected by spironolactone. Calcium and magnesium levels are also not directly impacted by spironolactone, making choices B, C, and D incorrect.

Correct Answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.
