Correct Answer: B

Rationale: Taking calcium supplements with meals is a crucial instruction for a client with osteoporosis. Calcium absorption is enhanced when taken with food, and proper calcium intake is essential for managing osteoporosis effectively by promoting bone health and density. Avoiding weight-bearing exercises (Choice A) is incorrect because these exercises help improve bone strength. Limiting vitamin D intake (Choice C) is also incorrect as vitamin D is necessary for calcium absorption. Increasing caffeine intake (Choice D) is not recommended as caffeine can interfere with calcium absorption.

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: B

Rationale: Fever and chills are classic signs of a transfusion reaction. These symptoms indicate that the body is having a response to the transfused blood, possibly due to incompatibility or an immune reaction. Elevated blood pressure (choice A) is not a typical sign of a transfusion reaction. Increased urine output (choice C) and bradycardia (choice D) are also not characteristic signs of a transfusion reaction. It is crucial to recognize symptoms of a transfusion reaction promptly to prevent further complications and ensure appropriate management.

Correct Answer: B

Rationale: The correct answer is B: Improved hemoglobin levels. Erythropoietin (Epogen) stimulates red blood cell production, leading to an increase in hemoglobin levels in clients with chronic renal failure. Monitoring hemoglobin levels is crucial to assess the effectiveness of erythropoietin therapy in managing anemia associated with chronic renal failure. While increased urine output, decreased blood pressure, and stable potassium levels are important parameters to monitor in clients with renal failure, they are not direct indicators of the effectiveness of erythropoietin therapy.

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.
