Correct Answer: C

Rationale: Using a hydrocolloid dressing is the appropriate care for a stage 2 pressure ulcer because it provides a moist healing environment, promotes healing, and helps to prevent infection. Cleaning the area with normal saline (Choice A) is important but not the primary treatment for a stage 2 pressure ulcer. Applying antibiotic ointment (Choice B) may not be necessary unless there is a sign of infection. Changing the dressing daily (Choice D) may disrupt the healing process and is not recommended unless the dressing is soiled or compromised.

Correct Answer: B

Rationale: Methimazole is the correct answer. It is commonly used to manage hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine (Choice A) is actually a medication used to treat hypothyroidism by supplementing thyroid hormones. Propylthiouracil (Choice C) is another anti-thyroid medication used in the management of hyperthyroidism. Prednisone (Choice D) is a corticosteroid and is not typically used in the treatment of hyperthyroidism.

Correct Answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

Correct Answer: B

Rationale: Glycosylated hemoglobin (HbA1c) is the most accurate test for long-term management of blood glucose levels in individuals with diabetes mellitus. HbA1c reflects average blood glucose levels over the past 2-3 months, providing valuable information on the effectiveness of treatment and disease control. Postprandial blood glucose, glucose tolerance test, and fasting blood glucose are essential for monitoring blood glucose levels at specific times but do not offer the same insight into long-term disease management as HbA1c.

Correct Answer: A

Rationale: The best method to monitor fluid balance in a patient receiving diuretics is to monitor daily weight. Daily weighing is a precise way to assess changes in fluid status as it reflects variations in total body water. Monitoring intake and output (choice B) is also important but may not provide as accurate a measurement as daily weight. Monitoring blood pressure (choice C) is essential but does not directly measure fluid balance. Monitoring edema (choice D) is helpful to assess fluid status visually but may not be as sensitive as daily weight measurements in detecting subtle changes in fluid balance.
