Correct Answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

Correct Answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

Correct Answer: C

Rationale: Clear lung sounds indicate that the antibiotics are effectively treating the bacterial pneumonia by resolving the infection and reducing the inflammation in the lungs, leading to improved air exchange and ventilation. Increased respiratory rate (Choice A) and decreased oxygen saturation (Choice B) are indicative of ongoing respiratory distress and ineffective treatment. Elevated white blood cell count (Choice D) suggests a persistent infection rather than effective treatment.

Correct Answer: C

Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a common complication post-thyroidectomy due to inadvertent parathyroid gland removal. Immediate intervention is required to prevent severe hypocalcemia manifestations like tetany or seizures. Hoarseness and a sore throat are common after a thyroidectomy due to surgical trauma and irritation to the vocal cords, not requiring immediate intervention. Difficulty swallowing can be expected due to postoperative swelling or edema, but it should be monitored closely. A temperature of 100.2�F is a mild fever and may be a normal postoperative response, not necessitating immediate intervention unless accompanied by other concerning symptoms.

Correct Answer: A

Rationale: Exercising in a swimming pool is beneficial for adolescents with juvenile rheumatoid arthritis as it reduces stress on the joints while allowing movement and strengthening. The buoyancy of water supports the body, making exercises easier and less painful, while also providing resistance to strengthen muscles. This form of exercise can help improve joint mobility and overall function without causing excessive strain on the joints. Choices B, C, and D are incorrect because splinting affected joints, performing passive range of motion exercises, or beginning a training program of lifting weights and running can potentially exacerbate symptoms and cause additional stress on the joints, which is not recommended for individuals with juvenile rheumatoid arthritis.
