Correct Answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

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: A

Rationale: The correct answer is to administer IV fluids. This intervention is the priority as it helps rapidly restore hydration in patients with dehydration by delivering fluids directly into the bloodstream. Monitoring intake and output (choice B) is important but comes after providing immediate fluid resuscitation. Administering oral fluids (choice C) may not be sufficient for a patient with dehydration who requires rapid rehydration. Providing electrolyte replacement (choice D) is essential but often follows fluid resuscitation to correct any electrolyte imbalances resulting from dehydration.

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.

Correct Answer: B

Rationale: Encouraging fluid intake is the best intervention for a patient with constipation. Fluids help soften stools, making them easier to pass. While stool softeners and laxatives can also help with constipation, they are more of a short-term solution and may not address the root cause. A high-fiber diet is beneficial for preventing constipation in the long run, but in the immediate situation of constipation, fluid intake is key.
