Correct Answer: A

Rationale: The correct answer is A because observing the patient for abnormal bleeding is an appropriate action to monitor for potential complications of warfarin therapy. This aligns with the nursing role in assessing and monitoring patient responses to treatment. B is incorrect as increasing warfarin dose without physician order can lead to adverse effects. C is incorrect as altering the dose without medical advice can be dangerous. D is incorrect as administering Vitamin K would counteract the effects of warfarin, which is used to prevent blood clotting.

Correct Answer: B

Rationale: The correct answer is B: Hematuria. Bacillus Calmette-Guerin (BCG) is commonly used in the treatment of bladder cancer. It works by stimulating the immune system to attack and destroy cancer cells in the bladder. One of the common side effects of BCG instillations is hematuria, which is the presence of blood in the urine. This can occur due to irritation of the bladder lining by the BCG solution, leading to inflammation and bleeding. It is important for the nurse to educate the client about this potential side effect so they are aware of what to expect during treatment. A: Renal calculi - BCG therapy is not commonly associated with the formation of renal calculi. C: Delayed ejaculation - Delayed ejaculation is not a common side effect of BCG therapy. D: Impotence - Impotence is not a common side effect of BCG therapy.

Correct Answer: C

Rationale: The correct answer is C: Avoiding the use of carbonated beverages. Carbonated beverages often have high sodium content, which can contribute to increased sodium intake. By avoiding these beverages, the client can significantly reduce their sodium consumption. Explanation: 1. Carbonated beverages often contain added sodium for flavor enhancement. 2. By avoiding carbonated beverages, the client eliminates a significant source of hidden sodium in their diet. 3. This dietary practice directly targets reducing sodium intake without compromising other nutritional aspects of the diet. Summary of other choices: A: Increasing the use of dairy products - Dairy products do not necessarily impact sodium intake significantly. B: Using an artificial sweetener in coffee - Artificial sweeteners do not contribute to sodium intake. D: Using catsup for cooking and flavoring food - Catsup is high in sodium and would not help in reducing sodium intake.

Correct Answer: A

Rationale: The correct answer is A: 11mg/dl. This patient is likely experiencing hypocalcemia, indicated by positive Trousseau's and Chvostek's signs. These signs suggest neuromuscular irritability due to low calcium levels. A serum calcium level of 11mg/dl is higher than normal, indicating possible hyperparathyroidism causing high calcium levels. Choices B, C, and D are lower than normal, which would exacerbate symptoms rather than alleviate them.

Correct Answer: C

Rationale: The correct answer is C, Disturbed body image related to the incision scar. This is the most appropriate nursing diagnosis as the client's concern about wearing a scarf around his neck post-surgery indicates a potential disturbance in body image. This diagnosis addresses the client's emotional response to physical changes, which is common in surgical patients. Choice A is incorrect because impaired physical mobility is not directly related to the client's worry about wearing a scarf. Choice B is incorrect as ineffective denial does not directly address the client's specific concern about body image. Choice D is also incorrect as the risk of injury is not the primary issue in this scenario; it is more about the client's perception of their appearance post-surgery. In summary, the client's worry about wearing a scarf post-surgery indicates a disturbance in body image, making choice C the most appropriate nursing diagnosis.
